For configuration control for centrally arranged modules, use the HW identifier for
•
the CPU.
If you have selected the CPU in the network view or device view, you can find the
HW identifier on the System constants tab of the Inspector window.
Use the value of the system constant "Local Configuration".
For configuration control for distributed I/O, use the HW identifier of the interface
•
module.
If you have selected the interface module in the network view or device view, you
can find the HW identifier on the System constants tab of the Inspector window.
Use the value of the system constant "<Name_of_interface_module> Head".
