Data can be exchanged between two TwinCAT systems on two PCs using TCP/IP. The exchange takes place asynchronously with respect to the cycle and depends on the network load – a local area network is advantageous for this purpose. For TCP/IP links, there are the ADSWrite and ADSRead function blocks for the exchange of data. An exchange via a field bus is also possible, in which case one PC is the master and the other is the slave.
