Using a Gateway

Case a: One gateway
If the CP you want to check with diagnostic functions can only be reached via a
gateway, you must select the device and specify its node address in the local
network.
You must also specify the S7 subnet ID of the destination network:
The subnet ID consists of two numbers separated by a dash:
- One number for the project
- One number for the subnet
You will find the subnet ID in the object properties of the subnet in the STEP 7
project. The subnet ID is also printed out with the network configuration.
