Modbus Explorer

Read and write to Modbus coils and registers

Description

The Modbus Explorer enables you to read and write to registers through Instrument Control Toolbox™ without having to write a MATLAB® script.

The Modbus Explorer offers a user interface to easily set up read and write operations, and a live plot to see the values. The read table allows you to easily organize and manage reads for multiple addresses, such as different sensors and switches on a PLC. The app supports a subset of the MATLAB Modbus functionality. You can do the following in the Modbus Explorer:

  • Read coils, inputs, input registers, and holding registers. This is the functionality of the Modbus read function.

  • Write to coils and holding registers. This is the functionality of the Modbus write function.

The app does not support the functionality of the Modbus writeRead function or the maskWrite function.
