Now define a channel to the target device which should be connected via the set
gateway:
Press button Scan network to search for available devices in your local network.
You should at least find the PLC installed with the PLC Designer setup: It will be
displayed indented below the gateway: instead of "WST06 [003C]" shown in the
picture below you should find the name and address of your computer. If your PLC is
not found, check if it is running, see (6).
Now select the PLC (device) entry and press button Set active path.
This will set this communication channel as the active one, which means that all
actions concerning communication will exactly refer to this channel. Notice this later
when you may have set up several communication channels in your project.
Close the Communication dialog with OK to apply the settings.
