Appendix A. What is Modbus TCP/IP?

Modbus is a communication protocol developed by Modicon in 1979.

Different versions of Modbus used today include Modbus RTU (based on serial communication like RS485 and RS232), Modbus ASCII and Modbus TCP, which is the Modbus RTU protocol embedded into TCP packets.

Modbus TCP is an Internet protocol. The protocol embeds a Modbus frame into a TCP frame so

that a connection oriented approach is obtained thereby making it reliable. The master query’s the

slave and the slave responds with the reply. The protocol is open and hence highly scalable.

Modbus Message Structure

Modbus devices communicate using a master-slave (client-server) technique in which only one device (the master/client) can initiate transactions (called queries). The other devices (slaves/servers) respond by supplying the requested data to the master, or by taking the action requested in the query.

A master’s query will consist of a slave address (or broadcast address), a function code defining

the requested action, any required data, and an error checking field. A slave’s response consists of fields confirming the action taken, any data to be returned, and an error checking field.

 Address specifies the address of the receiver.  Function Code specifies the message type.  Data is the data block.  Checksum specifies the numerical check value for testing the validity of the protocol.

A.1. Address

The first byte of information in the message structure of Modbus is the receiver’s address. The valid addresses are in the range of 0 to 247. Addresses from 1 to 247 are given to individual Modbus devices and 0 is used for broadcast.

A.2. Function Codes

The second byte in the frame structure is the function code. The function code describes what the slave is required to do. Valid function codes are between 1 and 255. The slave uses the same function code as the request to answer it. Only when error occurs in the system, the highest bit of

the function code will be made ‘1’. Hence the master will know if the message has been

transmitted correctly or not.

PET-7H24M Series User Manual, version 1.0.0 P.81

A.3. Data Field

The data field consists of messages sent between master and slave. The messages contain additional information about the action to be taken by the slave or any information requested by the slave. When the slave does not require this information the data field can be nonexistent.

A.4. Error Check

The error check performed in Modbus/RTU is Cyclic Redundancy Check (CRC). Both the transmitting device and the receiver compute CRC. Two bytes are used for this purpose and generally one bit errors are detected by this method.
