Hardware Monitoring AC500
i am trying to implement a monitoring of the AC500 I/O modules. For example i want a alarm if the supply is lost on one of them. This would be a PLC ok signal which is deactivated when one/several modules starts to malfunctioning. The PLC ok signal should be activated again when the module is "OK".
I have tried to use the function blocks "DIAG_INFO" togheter with the DIAG_Get. But dont understand how i could monitor whehter the alarm is active or not when i have read it once.
thanks in advance:)
