Instrument Control 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|
Instrument Control Toolbox supports the MODBUS interface over TCP/IP or Serial RTU. It is supported on the following platforms.
Microsoft® Windows® 64-bit
The Instrument Control Toolbox MODBUS support works on the MATLAB® command line only. It is not available in the Test & Measurement Tool.
