If the on Of the DO module is off in the System cabinet,
then what is the Procedure to check weather the Module is
working or not.
Answer Posted / ahmed samy
Make forcing from PLC programming software to any output Channel in that DO, if output is on, LED is on means module is ok, otherwise it's faulty.
Other idea, is to replace module with similar one in the rack, if it's still off in second position that means it has a problem
