ModbusTCP Server - Overview

On the CX80xx you can exchange data over a very widespread protocol with the aid of the ModbusTCP.
Use the documentation

TwinCAT ModbusTCP server

for this. The server is already installed on the CX80xx.

The X001 or X101/102 interfaces may be used.

Note

CX8091

The Modbus/TCP server is not part of the image of the CX8091.

Note

Required libraries

The corresponding libraries are located in the TwinCAT\Lib directory on the MicroSD card
and can be copied to the programming system using an SD card reader.

Note

CX8010, CX803x, CX805x, CX8080, CX8093, CX8095

The Modbus TCP can only be used with the X001 interface.
