Modbus Interface Supported Features

Modbus Capabilities

Industrial Communication Toolbox™ supports the Modbus^® interface over TCP/IP or Serial RTU. You can use it to communicate with Modbus servers, such as controlling a PLC (Programmable Logic Controller), communicating with a temperature controller, controlling a stepper motor, sending data to a DSP, reading bulk memory from a PAC controller, or monitoring temperature and humidly on a Modbus probe.

Using the Modbus interface, you can do the following tasks, which correspond to the Modbus function codes listed in the table.

Functionality	Modbus Function Code
Read and write coils	1, 5, 15
Read discrete inputs	2
Read and write holding registers	3, 6, 16
Read input registers	4
Perform mask writes on holding registers	22
Perform write/read (in one operation) on holding registers	23
