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".
Please Note
If possible, the option of using the " Network via client [
}
48] " protocol should be selected for performance
reasons.
4.1.7.3 Netzwerk via DCOM
If you need to allow data exchange between an OPC client and the TwinCAT OPC server over a network via
DCOM, this DCOM access type must be configured beforehand.
The following steps describe the necessary settings for the PC on which the TwinCAT OPC server is
installed.
Prerequisites

already set up for network operation (i.e. they have configured network cards running the TCP/IP protocol).
