ED 15063-5

Modbus Protocol Information Compatibility The MicroTech II Chiller Unit Controller can be configured in an interoperable Modbus network. The controller must have the corresponding Modbus Communication Module installed. The MicroTech II Chiller Unit Controller conforms to the Modbus Standards published at www.Modbus.org. See the Reference Documents on page 4.

Protocol Definitions The Modbus protocol is a standardized Application Level (OSI Level 7) protocol used in interoperable Industrial Control networks. Modbus provides the communication infrastructure necessary to integrate products manufactured by different vendors and to integrate control services that are now independent. It specifies how requests from the client are sent to a server and how servers reply. The client constructs a PDU (protocol data unit) and sends it to a specific server or broadcasts it to all servers. The PDU contains a function code that defines the action the client is requesting from the server(s). The PDU also includes a data field that further defines the action to the server, for example, the location of the data to be read. A normal reply from a server includes the same function code and a response data field. In the case of a read operation, the response data field contains the requested data. In the case of a write operation, the response data field contains an echo of the write data of the request command. If the server detects an error in the transmission, the reply to the client includes and exception function code and the response data field contains an exception code. Controllers can communicate on standard Modbus networks using one of two transmission modes: ASCII or RTU. Users select the serial port communication parameters (baud rate, parity mode, etc), during configuration of the controller. The mode and serial parameters must be the same for all devices on a Modbus network. Transmission mode determines how information is packed into the message fields and decoded. In RTU mode, each byte contains two hexadecimal characters, and in ASCII mode, each byte contains one ASCII character. The MicroTech II Chiller Unit Controller uses the RTU mode only. The MicroTech II Chiller Unit Controller uses the following data structure: 8 data bits, 1 or 2 stop bits, and no parity bit. It uses data transmission rates from 1200 to 19200 bps.

Valid Function Codes The MicroTech II Chiller Unit Controller supports eight public function codes. Function Code

Description

Definition

04 (0x04)

Read Input Registers

05 (0x05)

Write Single Coil

This function code reads status from 1 to 2000 contiguous coils in a remote device. This function code reads status from 1 to 2000 contiguous discrete inputs in a remote device. This function code reads the contents of a contiguous block of holding registers in a remote device. This function code reads from 1 to approx. 125 contiguous input registers in a remote device. This function code writes a single output to either ON or OFF in a remote device.

06 (0x06)

Write Single Register

This function code writes a single holding register in a remote device.

15 (0x0F)

Write Multiple Coils

16 (0x10)

Write Multiple Registers

01 (0x01)

Read Coils

02 (0x02)

Read Discrete Inputs

03 (0x03)

Read Holding Registers

7

This function code forces each coil in a sequence of coils to either ON or OFF in a remote device. This function code writes a block of contiguous registers (1 to approx. 120 registers) in a remote device.

ED 15063-5

Valid Error Codes The MicroTech II Chiller Unit Controller supports three error or exception codes. Error Codes Description Definition 01 02 03

Illegal Function Illegal Data Address Illegal Data Value

The function code received in the query is not an allowable action for the server (or slave). The data address received in the query is not an allowable address for the server (or slave). A value contained in the query data field is not an allowable value for server (or slave).

Modbus Data Point Each data point accessible from a Modbus network is described with a table that gives the data type and index. If the data point represents an enumerated variable, the enumerations are also listed.

Example Data Point: Chiller Enable This output data point indicates the current state of the chiller. The OFF state is represented by 0, and the ON state is represented by 1. (D2) Data Type

Index

Measurement

Units

Valid Range

Coil

2

Chiller State

NA

0 = Disable (Off) 1 = Enable (On)

Data Type

Data is represented as either single-bit elements or 16-bit elements. A single-bit element is referred to as a Discrete Input when it refers to read-only data and as a Coil when it refers to read-write data. A 16-bit element is referred to as a Input Register when it refers to read-only data and as an Holding Register when it refers to read-write data. Index

There can be as many as 65,536 elements of each data type in a Modbus device. Data elements are numbered from 1 to 65,536 in each type. Data elements are addressed with an index in the range from 0 to 65,535. The index is not the address of the data element in the unit controller memory. The index is used in Modbus PDUs to specify the location of the data in the unit controller. This means, for example, that data element number 1 is addressed using index 0 in the PDU. Valid Range

Some properties are standard data types and some are enumerated sets. If the property value represents a range of values, e.g., temperature or pressure, a range of values is given. If the property value is an enumerated set, all enumerated values and corresponding meaning are given.

Configuring the Unit Controller The MicroTech II Chiller Unit Controller and the Modbus Communication Module together are designed, programmed, and configured at the factory to be a chiller unit controller accessible over a Modbus network. No additional programming is required to make this a chiller unit controller. The unit controller is ready to operate with the default values of the various parameters set at the factory. Default values may be changed with the unit keypad or via the network. Parameters must be adjusted to accommodate your particular network. See the appropriate Operation Manual for default values and keypad operating instructions and the Modbus Communication Module Installation Manual (see Reference Documents section for manual part numbers.) When you have integrated the unit into your network, you can monitor and control unit operation from your workstation. At a minimum, you can: • Display and monitor data points • Turn the unit on or off • Operate the unit safely

Alarms Alarm Classes Modbus alarms in a MicroTech II unit controller are divided into three classes: Faults, Problems, and Warnings. Fault alarms have the highest severity level. Problem alarms have medium severity level. Warning alarms have the lowest severity level.

Fault Alarms Fault alarms require an acknowledgment from the operator. These alarms indicate that the compressor is shut down.

Problem Alarms Problem alarms do not cause compressor shutdown but limit operation of the chiller in some way.

Warning Alarms A warning is enunciated whenever an abnormal condition exists which does not affect chiller operation.

Alarm Handling One Modbus network variable indicates an alarm condition and one network variable clears alarms. To determine the particular alarm condition, you must read the status of the 16 Active Alarms Holding Registers.

Alarm Digital Output This network data point indicates whether an alarm condition has occurred. This variable must be polled for alarm notification. (D3) Data Type Coil

Index 4

Measurement NA

Units

Valid Range 0 = No Alarm 1 = Alarm

Clear Alarms This input data point clears all active alarms. It cannot clear all alarms in the Fault category (alarms that shut down the chiller). They would have to be cleared at the chiller panel. The alarms that cannot be cleared over the network (but can be cleared at the chiller) are: (D24) • Low Evaporator Pressure • High Condenser Pressure (by pressure sensor) • High Condenser Pressure (by pressure switch) • Low Oil Pressure • Freeze Protection • High Motor Temperature

Note: The above list is for centrifugal chillers. The flow loss alarm is the only alarm that can be remotely cleared on all other types of chillers. Data Type Coil

Active Alarms The Active Alarms Holding Registers contain a single bit for each alarm condition. You must read the status of these registers to determine the particular alarm condition indicated by the Alarm Digital Output. Table 3 defines the bit location for each alarm condition.
