System data types for connections to telecontrol servers or remote stations
You can configure the connection to the telecontrol server assigned to the S7-1200 or to a
remote station that can be reached via the telecontrol server with TCON_WDC. The address
data of the telecontrol server assigned to the CP can be found in STEP 7 in the "Telecontrol
interface > Mode" tab of the CP. The telecontrol server or a remote station is addressed
using the host name or the IP address.
The "RemoteWdcAddress" parameter of TCON_WDC specifies the Access ID of the
The "RemoteWdcAddress" parameter of TCON_WDC specifies the Access ID of the
connection partner.
