TwinCAT Modbus TCP Server

The TwinCAT Modbus TCP Server represents a connection of TwinCAT controls to the Modbus TCP world. Modbus TCP is a simple, manufacturer-neutral and open protocol. It is the “de facto” standard for control systems. The TwinCAT Modbus TCP Server represents a simple gateway between Modbus TCP and TwinCAT ADS devices. It can operate as a server or as a client. In server mode, TwinCAT memory areas are mapped directly to Modbus memory areas. In client mode, a number of PLC blocks are available that can be used to read inputs and input registers and to write coils and registers. The server is started directly with the start of TwinCAT. It is configured via an XML file.
