The added I/O modules appear in the PLC configuration under the "WAGO
750-343" slave along with their fixed addresses. You can declare your own
variables for the inputs and outputs of these I/O modules.
To declare variables, proceed as follows:
1.
Click on the "Resources" tab and open the PLC configuration.
2.
Double click beside the arrow on the entry "AT" and enter a variable name.
In this example, the names "PB_Input_Bit" and "PB_Output_Bit" were
assigned.
