Hi,
In previous versions of DeltaV (we are using 11.3), when the profibus cable was disconnected(had comms loss), we got a lot of alarms in the alarm list. Now, we don't get anything. Is it a setting somewhere we are missing, or our profibus isn't set up correctly, or this is the normal behavior in version 11.3?
Thanks,
Tibor
In contrast with FF instruments, Profibus devices do not have their own faceplates or alarms.
The alarms which you should get should come from all the control modules which have I/O assigned to the disconnected section. These shouldb be PVBAD / MODBAD alarms.
If you are not getting anything, check that the disconnected section is used in your control strategy and that these alarms in the control modules are enabled.
