AC30 EtherNet IP Option
Diagnostic Event
A single diagnostic event may be created. The severity is fixed as
Minor Recoverable.
This is represented on the network through the CIP Identity Object:
Identity Object (01h)
Instance #1
Attribute #5 (Status)
Bit #8 (Minor Recoverable Faults)
Three AC30 parameters are associated with the diagnostic event:
0187 Comms Event Set
A rising edge signal from FALSE to TRUE will create a diagnostic
event. The
Comms Event Clear
parameter must be set FALSE.
0188 Comms Event Clear
A rising edge signal from FALSE to TRUE will remove a diagnostic
event. The
Comms Event Set
parameter must be set to FALSE.
0186 Comms Event Active
This parameter indicates if a diagnostic event is active or not.
Note: The rising edge signals for Comms Event Set and Comms
Event Clear must be held for at least 10ms in FALSE and at least
10ms in TRUE to take effect.
When a diagnostic event is active the Module Status LED will flash
red.
