It polls the information provided by the device and sends to it commands and parameters. information that represents the dynamics of a functionality (e.g. the CB or a protection algorithm). It can be managed (i.e. set/reset) only by the device itself. after a protection trip, with relevant opening command to the release, CB stays in CLOSED state. In this case, the device tries to open the CB by starting a back-up procedure. Meanwhile, the device tries also to open the CB using the YO (through the I/O). command equal to CB Reset

Device RTU Framing

The allowed inter-character silent interval has been relaxed from ‘at least 2 characters’ to ‘at least 4 characters’ (the same silent interval to recognize the end of a message). This means:

2.2.1.

Silent interval < 4 char between two characters inside the message

In this case the receiver filters the silent interval and the following characters will be appended to those already received. The difference from the protocol specification is: 1.

Silent interval < 2 char between two characters inside the message Transmitter

Silent interval

4 char 1

2

4 char 1

...

3

n 4 char

Receiver 3

n 4 char

...

The behaviour is exactly as specified by the protocol. 2.

Silent interval  2 char and < 4 char between two characters inside the message The received characters are NOT flushed and the following ones will be appended. Silent interval

Transmitter 4 char 1

Note that after flushing, the standard protocol specification allows:  reception of the remaining characters of a partially received message  reception of a completely new message

The device behaviour doesn’t cover the second case because it always appends new incoming characters to the previous ones, leading to a CRC error. So the behaviour is exactly the same if and only if the incoming characters are NOT a new message. In this case the received packet will lead to a CRC error and the CRC error counter will be incremented.

2.2.2.

Silent interval  4 char between two characters inside the message

If the message transmission is NOT ended, all the previously received characters are managed as a message because this is exactly the protocol specification regarding the end of a message.

2.2.3.

New frame before 4 character silent interval at the end of a frame

In this case the receiver filters the silent interval and the following characters (of the new frame) will be appended to those already received. This will lead to a CRC error. Silent interval

Transmitter 4 char 1

So the CRC error counter will count both the ‘real’ CRC errors and the inter-character errors.

MODBUS MAP

Data format LINT (Acronym 1.3.1) (4 byte = 2 word = 2 register) is transferred with low significant part at lower modbus address (LOW-HIGH) Register i LS word Register i + 1 MS word Instead within WORD data the most significant byte is transferred first (as in MODBUS RTU standard) MS byte LS byte Since the PR122/P and PR332/P information set is a subset of PR123/P and PR333/P set, it was decided to represent them in only one general map from which is possible to deduce information of each device. PR123/P PR333/P

PR122/P PR332/P

For this purpose in each table it was foreseen a column named PR12x/PR33x in which, row by row, are shown the device and the product execution where the information has mean. The explanation of how to read column PR12x/PR33x follows: PR12x Meaning PR33x 3 Information available for PR123/P and PR333/P LSI/LSIG and NOT available for other units 3 Information available for PR123/P and PR333/P LSIG and NOT available for other units G 2/3 Information available for PR122/P and PR332/P LSI/LSIG, PR123/P and PR333/P LSI/LSIG and NOT available for S other units 2/3 Information available for PR122/P and PR332/P LSIG, PR123/P and PR333/P LSIG and NOT available for other units G 2/3 Information available for PR122/P and PR332/P LI/LSI/LSIG, PR123/P and PR333/P LSI/LSIG 2/3 The contained information in the line is worth for PR122/P, PR332/P and PR123/P,PR333/P Rc versions and is NOT Rc AVAILABLE for the other units The contained information in the line is worth for PR332/P and PR333/P versions and is NOT AVAILABLE for the 233x/333x PR122/P and PR123/P units The contained information in the line is worth for PR122/P and PR123/P versions and is NOT AVAILABLE for the 233x/333x PR332/P and PR333/P units MM The contained information in the line is worth for PR332/P MM unit and is NOT AVAILABLE for all the others units MM Not available for PR332/P MM unit Table 26 Code meaning WARNING: Parameters declared NOT AVALAIBLE for a unit are treated in the same way than the others, they are saved and checked in validity range but they are not used by the protections. Reading parameters declared NOT AVAILABLE could return not consistent data in respect to the ones previously programmed. Example: Program on PR122 the directional protection (NOT AVAILABLE for PR122) with the following data:  Prot D configuration = 0x0001 (Prot enable = ON)  Prot D Prot threshold Forward = 1 In Programming will be accepted because data is valid but D protection will remain disabled, therefore reading the parameters just programmed will return:  Prot D configuration = 0x0000 (Prot enable = OFF)  Prot D Prot threshold Forward = 1 In

RELAYS AND DATA LOGGER “CUSTOM” SETTING

Through the system bus it is possible to configure data logger trigger and programmable relays function in a more sophisticated mode, in the following way: Writing in “Data logger Trigger Type” or “Loc Bus Relay X Function” or “PX Function” registers (a value greater than list values) is possible to configure custom functionality as described in the following table. 15 OR AND

WORD (bits) 14 13 12 11 10 9 8 7 Byte placement (offset from 0x100 address) in the STATE; numeration start from 1.

Bits mask to be monitored in the byte

Table 65 relay and Datalogger custom setting Bit 7 ÷ 0: bit mask used bye trigger or function. Bit 14 ÷ 8: byte offset in the device STATE. Bit 15: if 0 means OR function among selected bits (mask), if 1 means AND function. Example 1: to configure data logger trigger type to stop when at least one of the listed conditions occur ( L tripped, S tripped, I tripped and G tripped) the value to write is: Bit 7 ÷ 0 = 00101011 (1 in correspondence of desired bits). Bit 14 ÷ 8 = 00001111 = 15 ( byte containing conditions is the 15th of STATE). Bit 15 = 0 (OR function). Therefore Data logger Trigger Type = 0x0F2B Example 2: to configure data logger trigger type to stop when all the listed conditions occur (UV Timing, RV Timing and RP timing) the value to write is: Bit 7 ÷ 0 = 10100010 (1 in correspondence of desired bits). Bit 14 ÷ 8 = 0001001 = 9 ( byte containing conditions is the 15th of STATE). Bit 15 = 1 (AND function). Therefore Data logger Trigger Type = 0x19A2

MEASURE HISTORY DATA STRUCTURE

The measure history log (0) contains the following information:  Marker  History code  Saving period  Day  Hour + minute  Total mean active power  Total maximum active power  Maximum current and relative phase  Maximum line voltage and relative phase  Minimum line voltage and relative phase The Marker (word length) is a general code for all non-volatile memory structure used to distinguish valid data (marker = 0x0000) from not valid data (marker = 0x5555) The history code has 3 types of recorded data: Nr. 0 = Normal record. Nr. 1 = First record after a supply power-up. Nr. 2 = First record after a saving period change.

Saving period mean, in the case nr.0 and nr.2, the elapsed time in minutes from previous record. In case nr.1 an almost empty structure is recorded only to show power supply returns; only Marker and History code have mean. Day, hour and minutes are the time-stamp of structure recording time. Could take place the following situations with e.g. saving period = 1hour. 1. Normal situation (history code 0): 1h

For e.g. after 27minutes from last recording time the Saving period is changed to 10minutes (history code 2): 1h

WAVEFORM AND HARMONICS

Sending a “start acquisition waveform + harmonics” command the acquisition of waveform samples (4.17) and the relative harmonics calculation can be obtained. There are two available commands: 1. Start acquisition: the waveform device resource is allocated to system bus, samples are acquired simultaneously from several channel and the harmonic calculation starts on selected channel. When calculation finish the glitch STATE bit “waveform available” is set. 2. Stop acquisition: the waveform device resource is released and become available for other requests (e.g. from HMI device); an eventual harmonic calculation in progress will be concluded before releasing the resource. Start acquisition command need a parameter field defining on which channel the harmonic calculation takes place; following table explains parameter and result link. Parameter value (L1) (L2) (L3) (Ne) (V12) (V23) (V31)

Table 57 Waveforms

Table 44 Harmonic measures L1 harmonic calc L2 harmonic calc L3 harmonic calc Ne harmonic calc V12 harmonic calc V23 harmonic calc V31 harmonic calc

Samples from L1, L2, L3 and Ne currents acquired simultaneously. Samples from V12, V23, and V31 line voltages acquired simultaneously.

Table 66 waveform and harmonics WARNING: All currents or all line voltages are acquired simultaneously but only for the selected channel there will be the harmonic calculation. Therefore sending a start command on a different channel ( in the same current or voltage block) allows to don’t start a new acquisition but only to calculate harmonics; sending command on the same channel it will generate a refresh of all samples before harmonic calculation.

Allocated resource WARNING: While the resource is allocated none could use it (an exception busy response will be returned); the STATE flag “waveform session status” show the allocation There is a 5minutes allocation timeout of resource once expired the resource is released. To continue the resource allocation 5minutes more it is sufficient to send a new start acquisition command before timeout ending

= 5,7 V = 922V = 0,5 In * 5,7 V = 16 In * 922V = 29,5 Hz (with hysteresis up to 31 Hz) = 80,5 Hz (with hysteresis up to 79 Hz) =2% = 500 %

Note: the measure of frequency is subject hysteresis in the intervals 29,5 Hz ÷ 31 Hz and 79 Hz ÷ 80,5 Hz, therefore it is valid in the range 31 Hz ≤ freq ≤ 79 Hz.

CONTACT WEAR

The contact wear is calculated as the usury sum owed at every single CB open and it’s explicit in % (0 ÷ 100[%]): It’s available in format 0 ÷ 65000 (0=0%, 65000=100%), therefore to obtain the percentage is necessary to divide the value for 650. Model
