The gateway will be installed with the installation of Intouch.
It is configured using the "System Platform Management Console".
With older Intouch versions it is called FsGateway. The configuration is the same.
Please make sure that the Poke Mode is changed to "Control Mode", otherwise not all values will be written into the PLC, write operations will be optimized away.
Please note the point after the connection name at "OPC Item ID Prefix" here "PLC1."
Gateway restart
Afterwards the gateway must be restarted, please do not forget.
The gateway is now ready to connect to the OPC server.
