Network via TwinCAT ADS

The TwinCAT OPC server performs the communication with the TwinCAT components (PLC run-time systems, bus terminal controllers etc.) via TwinCAT ADS. Since these services are also available in the network, the TwinCAT OPC server can also communicate with TwinCAT components that exist in the network.

You will find the settings needed for ADS communication over a network in the ADS Reference.

Network via TwinCAT ADS 1:

Settings in the OPC server

An ADS communication partner is always specified by two parameters: These are what is known as the "AdsAmsNetId" (e.g. 1.2.3.4.5.6) and the "PortId" (e.g. 801 for the first PLC run-time system).

If ADS is to be used to exchange data with, for example, the first PLC run-time system on another PC, then the AdsAmsNetId of the target PC, and "801" as the PortId, must be entered in the OPC server under "Device settings".

Network via TwinCAT ADS 2:

If possible, the option of using the "Network via client" protocol should be selected for performance reasons.
