Installation Requirements The installation of the M1550 shall comply with all local and national fire and electrical codes, i.e. NFPA 70, National Electric Code. In order to provide proper fire and electrical shock protection, the M1550 shall be powered from an isolated power source, use 14 AWG supply wiring provided with an 8A over current protection fuse. The fuse shall be located at the secondary of the source to properly protect the power supply secondary conductors. Field wiring should use 60°C copper conductors. The pluggable terminal blocks will accept 12-26 AWG wire. The wire should be stripped 0.310” and the terminal block tightened to the recommended torque, 0.79 N-m (7.0 lb-in.) Use appropriate gauge wire for the control circuit loads. Minimum 22 AWG wire is recommended for the Discrete Inputs. Minimum 22 AWG, twisted, shielded wire is recommended for the Analog Inputs and Analog Outputs. 14 AWG wire is recommended for the Discrete (Relay) Outputs. DC control signals should be segregated from AC power and AC control wiring by using separate wire ducts and separate conduit. The M1550 is an open type device that requires an appropriate enclosure, suitable to the installation site. The surrounding air temperature of the M1550 should not exceed 50°C (122°F).

Lithium Battery Replacement The internal lithium battery is a technician replaceable item. Caution: the lithium battery used in this device may present a fire or chemical burn hazard if mistreated. Do not recharge, disassemble, heat above 100°C (212°F) or incinerate. Replace battery with Panasonic, Part No. BR-2/3A or Micro-Comm Part No. BAT-004-3 only. Use of another battery may present a risk of fire or explosion. To replace the battery, remove all power to the unit. Caution – power to the relay contacts may be supplied from other equipment. Un-plug all of the terminal blocks and communications cables. Un-mount the unit and remove the four screws on the sides of the unit. Place the unit on a clean working surface and lift the mounting base from the face plate. The battery is located in the center of the face plate, clipped into the battery holder labeled J15. Use a small blade screwdriver to pry the battery clip to the side and up. Then pry on the other side to fully remove the battery clip. At this point the battery is held in place by the battery holder contact spring force and it is simple to remove the battery with your fingers. Place a new battery in the battery holder, matching the orientation of the “+” and “-“ markings on the battery to the battery holder. Replace the battery clip by pressing it into place. Mate the mounting base to the face plate and re-install the four screws. Re-mount the unit and plug all of the cables back into the unit. Dispose of the battery properly. Keep away from children. Do not disassemble and do not dispose of in fire.

Dip switches set both the address of the module and the baud rate used by the RS-485 connection to the RTU. ON 1 2 3 4 5 6 7 8
Switches 1-7 set the address (binary): Module #1 = switches 1-7 OFF Module #2 = switch 1 ON, 2-7 OFF Module #3 = switch 2 ON, 1,3-7 OFF etc. The baud rate is set using switch 8: 9600 baud = switch 8 off 19200 baud = switch 8 on The default baud rate used by the RTU is 9600 baud. This can be changed in the RTU Configuration 32 program if necessary. The normal COM3 Mirco-Comm I/O polling loop will take around 2.6 seconds to update all modules at 9600 or around 0.7 seconds at 19200 baud. Micro-Comm I/O protocol on COM3 currently supports (4) EDI16, (4) EDO16, (4) EAO4 and (2) EAI8 modules. All modules use Modbus RTU protocol and will be communicated with automatically using the “MicroComm I/O” protocol or can be communicated with manually using the MESSAGE() or MIOMSG() functions in script.

Use BKSP if you need to backspace. • Press ENTER when done with each entry. Special Modes: • Type .123 to get into the debug mode. Then hit the ENTER key to see a menu of choices. • Type .456 to get into the view communications screen. All radio communication data will then appear on the display. Press the up arrow to get out of this mode. • Type .741 to temporarily go from CTU32 mode to display mode. Note: This will only work if “hankshake” is disabled ahead of time since the RTS line will normally be off - see setup below. NOTE: The display communicates with the RTU using a serial cable (9 pin to RJ-11). The protocol options should be set to 9600 baud, 8 data bits, none parity, echo disabled. These are the factory defaults. To set a display back to factory defaults, hold down the PERIOD, ZERO and F1 keys during power up and then press the F1 key to load the defaults. The default for “handshake” is “enabled” (this will need to be disabled if you plan to use the temporary display mode described above). To change these parameters, press the PERIOD, ZERO and F1 keys any time after power up.

M1550 Configuration Program Installation RTU Configuration 32 is required for programming the M1550 PLC. RTU Configuration 32 is currently available for Windows NT/2000/XP and Mac OS X. To Install the Windows version, follow the steps below: When upgrading to a new version of the program, go to the Control Panels in Windows and double-click on Add/Remove Programs. Look through the list and remove any old versions of RTU Configuration. 1) Insert the CD into the CD-ROM Drive. 2) RUN the SETUP program located on the CD-ROM. 3) Follow the prompts and do a typical install. 4) After installation, the program icon will appear in the Start menu’s Program list.
When running the configuration program for the first time you will need to look at the serial port setup screen to make sure you have the correct COM port number selected. The port setup is located in the program’s “Edit - Preferences...” menu. Connection to the RTU is by means of a Null-modem cable from the computer’s RS-232 port to the RTU’s COM2 port (display port).
- 20 -
RTU Information Screen The RTU Information screen contains version, date, checksums, user information, address switch settings as well as a picture of the RTU. This information about the RTU will be available after the user has read the Personality Module. The Job Name and Site Name fields can be changed if necessary and the User Name and Last Programmed will reflect who made the most recent change. All the “User” information is sent to the RTU whenever the personality data is uploaded.
- 21 -
Configuration Parameters
The screen below shows a sample RTU Configuration dialog box. This screen is where all the operational parameters stored in the Personality Module can be changed (radio communications parameters, output timer settings, automote control settings and stop/start setpoints). To retrieve the personality data from an RTU, click on the blue down arrow icon or select Read Personality Data from the Transfer menu. After making changes, click the blue up arrow icon or select Program Personality Data from the Transfer menu.
- 22 -
RTU Configuration Parameters Model Number
The model of the RTU being configured is selected and shown here.
Protocol
The protocol selection for the radio communications port (COM1). Options include Micro-Comm RTU32, DF1 Half-Duplex Slave, DF1 Half-Duplex Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave, Modbus RTU Master or Modbus/TCP.
Baud Rate
This selects the speed for the radio communications port (COM1). 110, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bps are supported.
Parity
Parity checking mode (Even, Odd or None). Even parity should normally be selected when using Micro-Comm RTU protocol.
Data Bits
The number of data bits used by the radio port (5, 6, 7 or 8). This should normally be set to 7 for MicroComm RTU communications.
Stop Bits
The number of stop bits used by the radio port (1 or 2). This should normally be set to 2 for MicroComm RTU communications.
PTT
Time in milliseconds that will occur after the radio is keyed and before the data is sent out the radio port. This should normally be set to 250 msec or more for Micro-Comm RTU communications using conventional radios. Data radios will allow for much lower PTT times (50 msec or less).
Enable Modem
When this option is checked, the M1550 will turn on the internal 600 (or 110) baud radio modem. Leave this box un-checked when using an external radio modem.
Ant. Outputs
The range of 8 discrete outputs to use when a remote is doing Antenna/Radio switching. RTU32 protocol can only specify an 8 bit mask so this selection allows it to be applied to outputs 1-8 or 9-16.
Ant. Default
Discrete ouput number to leave on for Radio #1 when doing Antenna/Radio switching at a remote.
Station #
For use with Modbus or DF1 protocols ONLY. This sets the station # for this RTU as used by the protocol on all of the communication ports.
COM2 Protocol
Communication protocol used on COM2. This can be Micro-Comm Display, Micro-Comm RTU32, Micro-Comm CTU32, DF1 Half-Duplex Slave or Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave or Master, Modbus/TCP, Web Server, EtherNet/IP SLC and EtherNet/IP CLX (compact logix).
COM2 Baud
This selects the speed for the COM2 port. The default is 9600 baud for compatibility with the Micro-Comm Display Module.
COM2 PTT
Time in msecs that will pass after RTS is turned on and before data is sent out COM2. The default is 0 which will leave the RTS turned on all the time.
COM3 Protocol
Communication protocol used on COM3. This can be Micro-Comm I/O, DF1 Half-Duplex Slave or Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave or Master, Modbus/TCP, MicroComm Display, Micro-Comm RTU32, CTU32, EtherNet/IP SLC and EtherNet/IP CLX (compact logix).
COM3 Baud
Communications speed for the Micro-Comm I/O modules or for Modbus RTU / DF1 communication. The default is 9600 baud.
- 23 -
Timer Settings
The timer settings control how long the RTU will wait to energize or de-energize a relay output when it has been told to come on or go off. These timers will always be used regardless of the mode of operation - Micro-Comm CTU control, Script Language, Modbus or DF1.
Stop/Start Setpoints 1-32
These setpoints can be labeled and accessed from the Micro-Comm Display module and then used in script for control. Stop and Start setpoints are scaled using the analog selected in the Stop/Start Labels screen.
Use 8-bit Remote Setpoints
This option will force the remote setpoint protocol (used by SCADAview) to use 8-bit (LSB) values. This may be required if the central is a C2000 or earlier.
Pulse Dividers
These sets the number of pulses that must occur before the pulse input counter is incremented. Normally this will be set to 1.
COM4 Settings
The options for COM4 are similar to that of COM1 with the additional “Mode” option.
- 24 -
Ethernet (COM5) Settings
The options for the ethernet port are configured with the screen shown below:
Protocol
The protocol selection for the Ethernet Port (COM5). Options include Micro-Comm RTU32, DF1 HalfDuplex Slave, DF1 Half-Duplex Master, DF1 Full-Duplex, DF1 Radio Modem, Modbus RTU Slave, Modbus RTU Master, Modbus/TCP, Micro-Comm CTU32, Web Server, EtherNet/IP SLC and EtherNet/ IP CLX (compact logix).
Mode
This selects whether COM5 will be a TCP Server, TCP Client or UDP Mode (client/server).
IP Address
TCP/IP Address of the M1550 PLC on the network.
Subnet Mask
Selects the class of the local network (usually either 255.255.255.0 or 255.255.0.0)
Gateway
The address of the local network router (if any).
Reverse-Poll
Enabling reverse-poll when using CTU32 protocol will allow multiple computers (up to 4 using client mode) to receive status updates.
Local TCP Port
Port number used when we are a TCP Server. Our default is 4001. It will be forced to 44818 when using EtherNet/IP. It should also be changed to 502 when using Modbus/TCP protocol.
Max. Connect
The maximum number of clients that can connect to us when we are a TCP Server (1 - 4).
Destination IPs
If the mode is a TCP Client, these are the addresses and port numbers that the PLC will connect to.
Local Listen Port
Port number on which we will receive data from the other PLCs when using UDP Mode. This can be the same port as used for transmitting data. (4001 is our default).
UDP Ranges
When using UDP Mode, these ranges of IP addresses and port numbers will all be sent data when the PLC transmits. Note: Do not include the PLC’s own IP Address in these ranges.
The “Network Search” button will scan the local network for our PLCs. - 25 -
Analog Labels and Scaling Factors To change analog labels and scaling factors, click on the blue water tower icon or select Analog Labels & Scales from the View menu. The labels and scales are retrieved/sent to the RTU during reading/writing of the personality module configuation data. Up to 32 analog levels can be displayed and they will always appear in the order entered in the setup screen. If an analog label is left blank it will not show up on the display. When analog levels are displayed, the offset is first added to the raw analog value and the result is then multiplied by the range value. (This matches the Micro-Comm SCADAview program). A Range/Preset calculator (shown below) can be displayed by right-clicking and selecting the menu option.
- 26 -
Output Timer Labels To change the 20 character output timer display labels, click on the clock icon or select Timer Labels from the View menu. The labels are retrieved/sent to the RTU during reading/writing of the configuration data. These labels are normally used for pumps and provide both ON and OFF delays entered on the MicroComm Display Module. Note: Lines where the label is left blank will not be accessible from the Display Module.
- 27 -
Stop/Start Setpoint Labels
Stop/Start labels are used on the Display Module to allow the operator to change operational parameters such as Pump Stop/Start setpoints, High/Low alarms and Pump Restore/Cutoffs. Along with the 20 character label is a selection for what type of setpoint (Stop/Start, High/Low etc.) and which analog input # will be used for scaling and units. Note: Lines where the label is left blank will not be accessible from the Display Module.
- 28 -
X Variable Labels
User variables are the 16-bit unsigned integer X1-X32 script language variables that can be used for any purpose. By entering a label in the User Variable Labels setup screen, the current value will be shown and can be changed on the Display Module.
- 29 -
Discrete I/O Labels
Labels for both 32 discrete inputs and 32 discrete outputs are user defined in the RTU Configuration 32 software. These labels may be used to display pump calls, pump runs, valve positions, alarms etc. A 12-character label is used to name the input or output along with a 6-character ON label and a 6-character OFF label to describe the on or off state. If the input or output name is left blank it will not appear on the display and if no discretes are labeled the display will just skip over the entire section (inputs or outputs). The screen below shows the Discrete Input Labels setup screen:
- 30 -
User Memory Screens User memory screens allow for display and entry of data stored in user memory (locations 0-15999 in the M1550). The raw data type can be either 16 bit or 32 bit (using 2 consecutive user memory locations) and can be displayed as numeric, discrete labels or binary numbers. The user memory screens are accessed by arrowing all the way down to the bottom row of the MicroComm display. The sample screens below show how a 32bit flow total could be displayed and how a pump HOA selector could be configured.

User Memory Database Editor The User Memory Database screen provides the capability of reading, programming and editing all user memory locations (0-15999) as well as saving and loading a comma seperated (.CSV) database file. This file could then be used for data logging/trending or saving a backup copy of important data such as flow totals, runtimes etc. The screen shown below is accessed from either the Utilities menu or by selecting “Read User Memory” from the Transfer menu.
Right-clicking on this screen will bring up a menu with options to “Read User Memory”, “Program User Memory”, “Save CSV File...” and “Load CSV File...”. Double-clicking on a cell will put it into edit mode and a new integer value can be entered. The data will be displayed and entered in decimal unless the “Display User Memory and X Variables in Hex” is selected in the preferences. This screen can also be made to show “live” data like the user memory data table viewer by selecting the “Auto-Refresh User Memory Database Window” option in the application preferences. NVRAM Database In addition to the User Memory Database, there is also a very similar NVRAM Database window which can be used to download and save data from the RTU’s personality module. This could be used for longterm data logging since it currently supports 65000 words of data. The script commands NVREAD, NVWRITE and NVCOPY are used to manage this data.

RTU Script Language Editor To enter or edit the Script Language Code, click on the script icon or select “Script Editor” from the View menu. Script language can be retrieved from the RTU by clicking the Read button shown at the bottom of the editor window or by selecting Read RTU Script from the Transfer menu. Lines starting with a single quote character are comments and do not get sent to the RTU when programming. Comments are saved in the .S5C configuration file and can optionally be saved to the RTU in place of the revision notes. After entering lines of code the user can click the Check button to make sure the syntax looks ok and to see how many bytes of code have been used. Currently the main script code can’t be larger than 16894 bytes. The code is then programmed into the RTU personality module by clicking the Program button or by selecting Program RTU Script in the Transfer menu. Script subroutines are edited by selecting the subroutine number from the list in the lower-left corner of the screen. Each subroutine can be read, programmed and checked separately using this editor. Currently each subroutine can be up to 2110 bytes.
- 33 -
Revision Notes Editor To enter or edit the Revision Notes for the RTU, click on the notepad icon or select Revision Notes from the View menu. The screen below shows some sample notes - they can be script comments, software description, revision history, variable tables or anything else desired. The Read and Program buttons are used to retreive or store the notes in the personality module. Revision notes are also saved in the .S5C configuration file. If the option “Use Commented Script for Revision Notes” is turned on in the preferences, this screen will be filled in with the current commented script whenever it is opened. It can then be programmed into the personality module in addition to the un-commented (compiled) script. The user will also then be asked if the commented script should be programmed whenever the configuration or compiled script is programmed. Commented scripts can be read back from an RTU and imported into the actual script by right-clicking and selecting the “Import Commented Script” menu option (shown below).
- 34 -
Data Table Viewer The Data Table Viewer screen allows the operator to see and change I/O variables, User variables and the Stop/Start setpoints in real-time when connected to an RTU. This screen can be very useful when debugging script language code. The User Memory data table can display all user memory (a range of 64 locations at a time) and will allow for changing these values. Analog inputs and Stop/Start setpoints are displayed as raw 12-bit numbers (0-4095) or can optionally be scaled based on the range/offset values entered in the analog setup screen. Pressing the “S” key on this display will toggle scaling on and off. Discrete inputs and outputs are shown as either 1 or 0 (on or off). When the “Force I/O” option is selected, the I/O variables shown in red may be changed to the desired value by clicking on the readout box, typing a new value and pressing enter. When the “Disable Script” option is also checked, the script will stop running and any I/O that it was controlling will then be accessible.
- 35 -
Display Module Emulator
The display module is an optional hardware component to a M1550 PLC which allows an operator to see levels and change setpoints. When programming the M1550 with the RTU Configuration 32 software the operator can use the Display Module Emulator screen to see what the display module would show. This can be very useful since both the display module and the programming software may be using the same com port on the RTU.
- 36 -
Debug Terminal The Debug Terminal screen allows the user to interact directly with the RTU over the programming port (COM2 or COM3) or with other third-party serial equipment. It will display incoming data using ASCII, Modbus or DF1 mode based on the “Display Mode” selection in the lower-left hand corner of the screen. Protocol analysis of master messages (requests) can be done by selecting “RTU32-Decode”, “ModbusDecode” or “DF1-Decode”. Data logging can also be done by clicking on the “Log Data...” button and typing in a file name. Radio communications on COM1 can be monitored on COM2 - COM5 by clicking on the “COM1” button, COM2 can be monitored on COM3-COM5 by clicking the “COM2” button etc,etc. The “Debug” button will enter a hardware debugging mode where outputs can be turned on and off, inputs can be read, the clock can be set etc. Press the Enter key when in this mode to get a menu.

The parameters are as follows: gnum group number (1-128) uloc memory location for the start of the crontol group data structure genable group enable flag (1=enable, 0=disable) - group will alternate when disabled gtype group type (1=normal, 2=normal + RTU HOAs, 3=discrete given # of pumps, 4=discrete given # of pumps + RTU HOAs), 5=pump-down, 6=pump-down + RTU HOAs) clevel analog control level for comparison with stop/starts or the required # of pumps if using a type 3 group psaddr primary pump station address (0-255 = HH-WW) npumps number of pumps to control at the primary address (1-8) spump starting pump output number at the primary address (1-8) penables pump enable binary mask (0=no pumps enabled, 65535=16 pumps enabled) failsecs number of seconds to wait for a run before failing a pump (0=no fail) Optional parameters (psaddr2, npumps2, spump2 etc.) can be used to define up to 3 more pump station addresses and outputs to be controlled by the group. The maximum total number of controlled pumps is 16. The GROUP() function will return the current # of pump calls. IF(x,y,z)
If x is true evaluate y else evaluate z (else is optional). Multiple statements may be used for y or z by separating them with a colon. Example: IF(DI1, DO1=1:DO2=1, DO1=0:DO2=0)
LABEL(x)
Marks a line in the script that could be jumped to using the GOTO(x) function. This should be by itself on a line of script - see the GOTO(x) function for more info.
LISTEN(saddr, uloc, lostime [, ant#, rly1, ant1, rly2, dbrly, tbrly, pdaddr, pdoff, pdmask] ) Defines station addresses to listen for when using either Micro-Comm RTU/RTU32 (automote messages or replies), old-style PDU messages or Modbus RTU Slave replies. When using MicroComm protocol, this function returns a “1” as long as the station is not in LOS. Also, the actual time in seconds since a reply was heard can be found in the station data structure. The parameters are: saddr address number (0-255 = HH-WW) or Modbus Slave address to listen for uloc starting user memory location for the station data structure lostime time in seconds before the LOS bit will be set in the station status byte ant#, rly1, ant1, rly2, dbrly, tbrly - optional parameters that a central may need to talk to a non-polled remote (for remote HOA or Control Group information). These parameters are the same as shown for the MESSAGE function. pdaddr old-style PDU string address to listen for (PDU parameters are also optional) pdoffset starting location in pdu string for this station’s data pdmask data that is expected to be in the PDU string for this station (see the MPDU function) Example: X1=LISTEN(@PI,200,480) This would listen for station address “PI” and save the station data structure starting at user memory location 200. X1 will equal 1 as long as the station is not in LOS (480 seconds). Note: When using Modbus RTU Slave protocol, the reply data is just saved in a block starting at the uloc. The Modbus replies must be to “Read Holding Register” messages (4x registers). MAVG(uloc, nwords) Returns the average value from a given range of user memory locations: uloc = the starting user memory address nwords = number of words to average
- 42 -
MCOPY(src, dst, nwords) Copies data from one area of user memory to another using the following: src - starting user memory location for the source data dst - starting user memory location for the destination data nwords - the number of words (16bit numbers) to copy Example: To copy the first 10 words from uloc 100-109 to uloc 200-209 MCOPY(100,200,10) MCRC(uloc, nwords) Returns the CRC 16-bit checksum of a given range of user memory locations: uloc = the starting user memory address nwords = number of words MDATA(uloc, d1 [,d2, d3, ...]) This function simply copies the given data words into consecutive user memory locations and returns the total number of words copied. uloc - starting user memory location for the data d1, d2, d3, ... - data words to place into memory (can be as many as needed) MDECTOHEX(dval, uloc, nchars) Converts an integer value to an ASCII hex string of characters located in user memory. dval - value to convert (16 bit unsigned integer) uloc - starting user memory location of the hex string nchars - number of hex characters (1-4) MDISPLAY(row, column [,editflag]) Changes what is being displayed on the Micro-Comm Display Module by moving to the given row and column. The “row” should be one of the following: 1=Analog Input Labels, 2=Discrete Inputs, 3=Discrete Outputs, 4=Timer Settings, 5=Stop/Starts, 6=X Variable Labels, 7=User Memory Screens. If the optional editflag parameter is set to “1”, the displayed screen will immediately go into edit mode (just as if the user had pressed Enter). Example: This will change the display to user memory screen #1 whenever an alarm input on DI3 goes on. The user memory screen should be set up to show an alarm message. IF(OSR(DI3,0),MDISPLAY(7,1,0)) ‘ uses the one-shot function so that it won’t keep doing it.

MIOMSG(port, type, timeout, addr, ref, offset, npts, uloc, lostries) Sets up a high-speed (background task) Micro-Comm I/O-Modbus RTU message loop. Unlike normal user messages, these can have timeouts as small as 30 msec. port - communications port number (3, 4 or 5) type - message type (0=Read, 1=Write, 21=User Memory Setpoints) timeout - amount of time in milliseconds to wait for a response addr - address of the modbus slave device (0 to 247) ref - modbus reference location in the slave to start reading or writing offset - offset added to the reference location npts - number of data points to read or write uloc - user memory location for the data lostries - number of polling tries before done bit goes to 0 (returned value) Example: X1=MIOMSG(3,0,50,0,40001,0,8,100,4) ‘reads analog input module (AI1-AI8) MLCALC(oper, uloc1, uloc2, ruloc) Allows 32 bit math (unsigned long integer) functions to be performed on user memory data. oper - operation to be performed (1=add, 2=subtract, 3=multiply, 4=divide, 5=raise to power) uloc1 - user memory location of the first long integer uloc2 - user memory location of the second long integer ruloc - user memory location for the result Example: MLCALC(1,113,213,10) ‘M10=M113+M213 MPDU(uloc, saddr, pdmask) Adds old-style PDU data to a range of user memory locations. It returns the total number of words copied to user memory. This is used in conjuction with Type 18 messages to send old-style PDU strings. uloc - the starting user memory address saddr - station address to get the data from (0=HH - 255=WW) pdmask - bit mask with b0-b8 set based on what data is to be copied: (b0=Analog A, b1=Analog B, b2=Discretes, b3=Flow Rate, b4=IEM, b5=Pump 1-4 C/F, b6=Pump 5 C/F, b7=Analogs C,D, b8=Analogs E,F) Note: All analog data should be scaled to 8-bit. MREAD(uloc)
Returns the 16bit word stored in user memory location uloc (0-15999).
- 48 -
MSGDONE(port, type, uloc [, sparam]) Returns the done status for a message given the port number, message type and uloc (these 3 parameters should uniquely identify the message). If both type and uloc are zero, a value of “1” will only be returned if all messages for the given port are done. The done bit can also be set or cleared using the optional “sparam” parameter. If the optional “sparam” parameter is 0 or 1, the done bit will be set accordingly. Other parameter values will do the following: 2 = returns the done counter (0-65535) 3 = returns the fail counter (0-65535) 4 = returns the done percentage x 100 (0-100% = 0-10000) 5 = resets both the done and fail counters Note: Whenever the done or fail count rolls over to zero, both counters will be reset and percentage will go to 10000. Also, done and fail counters are incremented whenever a message is successful or unsuccessful (unlike the done bit status which get’s cleared based on the message command’s “lostries” parameter). MSGNUM(port)
Returns the current user message number pending on the given communications port (1-5). The message number is it’s location in the script with relation to other messages on the same port. Message numbering starts at “1”.
MSUM(uloc, nwords) Returns the sum of a given range of user memory locations: uloc = the starting user memory address nwords = number of words to sum MSYNC(sync#, uloc1, uloc2, nwords) Keeps two blocks of user memory in sync. If a word in block 1 changes, block 1 will be copied to block 2 and vice versa. The parameters are: sync# - a unique sunc function number (1-64) uloc1 - starting user memory location for block 1 uloc2 - starting user memory location for block 2 nwords - the number of words to keep in sync (block size) Note: Block 1 is the “master” so if both blocks change, block 1 will be copied to block 2. Example: MSYNC(1, 100, 200, 100) ‘keeps M100-M199 in sync with M200-M299 MWRITE(uloc, y) Writes the 16bit variable or constant y to the user memory location specified by uloc (locations from 0-15999 are supported). NVCOPY(src, dst, nwords, direction) Copies a block of data from the personality module NVRAM to User Memory or from User Memory to NVRAM given the following parameters: src - source uloc or nvloc location depending on direction of copy dst - destination uloc or nvloc location depending on direction of copy nwords - number of 16bit words to copy direction - 0=NVRAM to User Memory, 1=User Memory to NVRAM NVREAD(nvloc)
Returns a 16bit word stored in the personality module NVRAM location nvloc (0-65471)
NVWRITE(nvloc,y) Writes the 16bit variable or constant y to the personality module NVRAM location specified by nvloc (locations 0-65471 are supported) OSR(x, osr#)
One-shot rising function. This function will return a “1” only once whenever the x parameter goes from 0 to non-zero (false to true). The osr# parameter must be a unique number (0-255) for each OSR() function used in script. Example: IF (OSR(DI1,0),X1=X1+1) ‘counts the number of times DI1 goes on...

PID(t, ai#, ao#, p, i, d, min, max, start, dband, period) Sets the parameters for a real-time PID module. Setting “ai#” to 0 disables the PID. When reenabled, the analog output will start again at the “start” value. A total of 8 PIDs (one for each analog output) can be running at the same time. The PID will use a scaled value for the analog input and will internally keep track of a “raw” analog output value so that it can be scaled in the script as well. The PID() function will return the “raw” analog output. t = target setpoint (0-4095) ai# = analog input # used (1-64) ao# = analog output # used (1-8) p = proportional term x 1000 (0-65535) i = integral term x 1000 (0-65535) d = derivative term x 1000 (0-65535) min = minimum analog output (0-4095) max = maximum analog output (0-4095) start = starting value for analog output (0-4095) dband = deadband (output will hold when input is this close to the target) period = time period in seconds for the PID calculation Example: AI1=SCALE(AI1,819,3604,0,255) ‘scale AI1 300# xdcr 4-20ma => 0-255 psi PID(X1,1,1,100,10,6,0,1000,500,20,4) ‘PID using AI1,AO1 and X1 target (0-255) AO1=SCALE(AO1,0,1000,819,4095) ‘scale AO1 0-1000 => 4-20ma output PITOAI(pi#, ai#, maxp, maxa, maxt) Sets the parameters for real-time pulse to analog conversion. pi# - pulse input # (1 - 64) ai# - analog input # (1 - 64) maxp – maximum pulses-per-sec x 100 maxa - maximum analog input reading (0 to 65535) maxt - maximum # of seconds between pulses before AI goes to zero. Example: PITOAI(1,3,1000,4095,2) This converts a pulse of 0-10pps on PI1 to a value of 0-4095 on AI3. If 2 seconds goes by without seeing a pulse, AI3 will be set to 0. PMEM(x)
Returns a byte from the RAM copy of the personality module configuration (locations 0-127). Refer to the personality module memory map for more info. Some locations will return current status information.
POLYNOMIAL(x, xexp, c, cexp, a1, a1exp, a2, a2exp, a3, a3exp, a4, a4exp, rexp) Computes the result of a 4th degree polynomial function: f(x) = const + a1*x + a2*x^2 + a3*x^3 + a4*x^4 x = given variable x xexp = exponent multiplier for x (10^xexp) c = constant value cexp = exponent multiplier for contant (10^cexp) a1,a2,a3,a4 = polynomial parameters a1exp,a2exp,a3exp,a4exp = exponent multipliers for parameters a1-a4 (10^aexp) rexp = exponent multiplier for the return value (10^rexp) Example: M1=POLYNOMIAL(M0,0,17879,-3,-40821,-4,34023,-5,-40364,-7,14639,-9,2) This computes the following polynomial and return the result *100. f(M0) = 17.879 - 4.0821*M0 + 0.34023*M0^2 - 0.0040364*M0^3 + 0.000014639*M0^4 POW(x, xexp, y, yexp, rexp) Returns the value of x raised to the y power. Pre-scaling and post-scaling is done using the given exponent parameters. The result is rounded up to the nearest unsigned integer value. Equation used is: result = ( (x * 10^xexp) ^ (y * 10^yexp) ) * (10^rexp) Example: X2=POW(222,-3,2,-1,4) would return a value of 7401 computed using: (0.222^0.2)*10000 = 7401

PUMPFAIL(callvar, runvar, tsec#, failsecs) Returns a “1” if the call variable has been equal to “1” for more than the fail seconds while the run variable is zero. This fail will clear on it’s own if the run occurs at some later time. The parameter parameters are: callvar - call variable or expression (usually an output) runvar - run variable or expression (usually an input) tsec# - TSEC timer # to be used (1-224) failsecs - seconds before fail is generated Example: X1=PUMPFAIL(DO1TD,DI1,1,240) RAMP(ramp#, startValue, endValue, rtimeSec) This will return the start value when first called and then will ramp up (or down) to the given ending value over the given period of time (in seconds). The parameters are: ramp# a unique number for the function (1-8) startValue value to start with (when the function is first called) endValue value returned at the end of the ramp time rtimeSec time period in seconds for the ramp to occur Example: AO1=RAMP(1,819,4095,120) This would ramp analog output #1 from 819 to 4095 over a 2 minute period. RESPOND(saddr, uloc [,protocol [,nobuild] ]) Defines an additional station address for the RTU to respond as when polled with RTU32 protocol or Modbus protocol if optional flag is set. The parameters are: saddr station address number (0-255 = HH-WW) uloc memory location for the station data structure protocol when this optional parameter is a “1”, the given address and uloc will apply to Modbus protocol instead of RTU32. In this case, the uloc defines a new starting location for the Holding Registers (4x0001). All other Modbus data types will remain the same. nobuild when this optional parameter is set to “1”, the station status and timestamp will not be updated locally - this may need be used if all the station’s data is being read from another RTU using a protocol other than RTU32. Example: RESPOND(129,3200) defines RTU32 address “PI” with station data located at 3200. REPLYWITH(saddr, MR) Forces the reply message type to use when responding with RTU32 protocol. This could be used, for instance, to send certain data only when necessary (report-by-exception). The parameters are: saddr station address (0-255 = HH-WW) MR read message type to reply with (see RTU32 Protocol table) - a value of 255 will cancel the forced reply and go back to what is asked for. RUNCOUNTER(cnum, cvar, uloc) Counts the number of “on” cycles for the given variable. The counter is incremented whenever the value of cvar goes from zero to non-zero. The parameters are: cnum unique counter number (1-128) cvar variable or expression to count uloc user memory location used to store the counter (16 bit) RUNTIMER(tnum, tvar, uloc) Provides a run-time meter on the given variable. The run time is incremented in 10ths of hours while the value of tvar is non-zero. The parameters are: tnum unique timer number (1-128) tvar variable or expression to time uloc user memory location used to store the timer (16 bit) - 10ths of hours
- 51 -
SCALE(raw, rmin, rmax, smin, smax) Returns a scaled value given the actual raw value, the minimum/maximum raw values and the minimum/maximum scaled values. Example: AI1=SCALE(AI1,819,4095,0,4095) SELECT(test, value1, statement1 [, value-n, statement-n]) Similar to the IF function, SELECT will evaluate the given test expression and execute one of the statements based on it’s value. If the test expression is equal to value1, statement1 will be executed. If test is equal to value2, statement2 will be executed and so forth. Multiple statements may also be used by separating them with a colon. Example: SELECT(X1,100,DO1=1,200,DO2=1,300,DO3=1) This will turn on a discrete output based on the value of X1. SFTABLE(addr1, addr2, antmask, timeout) Modbus RTU, DF1 Half-Duplex and DF1 Radio Modem protocols allow for relaying messages via the “Store & Forward” method when using COM1. A lookup table is used to translate incoming message addresses to a relayed-to station address. The following parameters sets up an entry in the Store & Forward table: addr1 address the master is using for the remote station being relayed to addr2 address this RTU will use to get the data from the remote station antmask antenna mask used for switching radios or antennas during the relay - this is an 8-bit mask applied to either DO1-DO8 or DO9-DO16 based on the configuration selection timeout amount of time in milliseconds the RTU will wait for a response SQR(x [, xexp, rexp]) Returns the square root of x with optional parameters for pre-scaling and post-scaling. Equation used is: result = sqrt( (x*10^xexp) ) * 10^rexp Example: X1=SQR(256,-3,4) would return a value of 5060. SDATA(saddr, word#) Returns the value of a given word number from the “Station Data Structure” for Micro-Comm stations obtained using the MESSAGE() or LISTEN() functions. The station data structure is shown later in this manual. Example: X1=SDATA(@TH, 4) returns the value for AI1 from station TH. SSTATUS(saddr, bit#) Returns the state of a given status bit number from the “Station Status” word for Micro-Comm stations obtained using the MESSAGE() or LISTEN() functions. The following bits are defined: b7 (LOS) set when station goes into Loss of Signal (user defined) b6 (Data Valid) set when the received data is less than three cycles (tries) old b4 (Control Valid) set when data is first received and cleared at LOS Example: X1=SSTATUS(@TH, 7) returns a “1” if station TH is in LOS. SUB1(x)-SUB20(x)
Calls a subroutine and returns the EXIT(x) value to the main script routine. Currently up to 20 subroutines are supported. Values can be passed to a subroutine using the following syntax: SUB1(x1,x2,x3,x4,x5) Where x1 through x5 are 16bit integer variables or constants passed by value to the subroutine. They become local variables referenced as L1 through L16 from within the subroutine. Example: The following shows the main script and a subroutine. The subroutine totals up the three values passed and returns the result to the main script. The main script stores the result in the X1 variable. Main Script: X1=SUB1(1,2,3) Subroutine #1: L4=L1+L2+L3 EXIT(L4)

TCLOCK(iTime, rTime, iDay, PFRate, CLevel, CStop, OvrStop, OvrStart, uloc) This is a timeclock control function that provides for time inhibit/restore, prefill and override setpoints. The return value and the given user memory location will have it’s bits set as follows: b0=time inhibited, b1=prefill call, b2=override call (level below the override start) The parameters are: iTime - inhibit time (military time format 0-2359) rTime - restore time iDay - inhibit day-of-week (0=every day, 1-7=Sunday-Saturday) PFRate - prefill rate in units/hour (units the same as CLevel) CLevel - control analog level CStop - normal control stop setpoint (top-off level for prefill) OvrStop - override stop setpoint OvrStart - override start setpoint uloc - user memory location to use for the inhibit and call bits TIME(x) Returns a system time value based on the requrested parameter number. The parameters available are as follows: 0 - Seconds since power-up (rollover at 65535) 4 - Year (0-99) 1 - Day of the week (Sunday = 1) 5 - Hours (0-23) 2 - Month (1-12) 6 - Minutes (0-59) 3 - Day (1-31) 7 - Seconds (0-59 8 - Seconds since being polled by a central on COM1 - stops at 65535 secs (for central LOS) 9 - Seconds since being polled by a PC using CTU32 protocol on COM2-COM5 (for PC LOS) 10 - Seconds since polled by master on COM2, 11 - Seconds since polled by master on COM3 12 - Seconds since polled by master on COM4, 13 - Seconds since polled by master on COM5 TOTALIZE(pi#, ppc, uloc, nwords [,maxdelta]) This totalizes one of the high-speed pulse inputs given the following: pi# - pulse input register number (1-64) ppc - pulses per totalizer count uloc - user memory location for the totalizer register nwords - totalizer storage size in # of words (1 or 2) maxdelta - optional parameter to set the maximum change in pulse count that will be considered valid (the default is 32767). This can be used to avoid problems with external pulse registers. Example: TOTALIZE(1,1200,13,2) - increments a 32bit totalizer (2 words starting at user memory location 13), every time PI1 increases by 1200 (this could be a flow meter with 1200 pulses per 1000 gallons). XCOPY(msrc, mdst, nwords) Copies data from one location in the RTU to another (including I/O locations) given the following parameters: msrc - start modbus location for the source data mdst - start modbus location for the destination data nwords - the number of words (16bit values) to copy Note: msrc and mdst locations will correspond to the Modbus reference location shown in the DF1Modbus protocol table minus 400000. Supported memory locations include all the I/O data (1-166), X Variables (201-424) and User Memory Locations (3000-11999). Example: To copy the first 16 discrete inputs to X2, the command is XCOPY(1,202,1)

Micro-Comm Script Language - RTU Processing Flow Chart Much like a PLC processing ladder logic, the script is executed in a continuous loop. All I/O is read and written outside of the script so all changes made to inputs or outputs will actually occur when the script finishes.
Read Inputs (analogs, pulses, discretes)
Respond to Interrogations Update the User Display Run Script General Housekeeping...
Write Outputs (start timers etc.)
Note: The M1550 can now respond to interrogations during script. This can cause undesired results when reading/writing user memory while this same memory is being manipulated in script. See the “MEMLOCK” variable for information on how to enable this feature. (setting MEMLOCK equal to 0 will allow incoming communications to access user memory)
