Interface Health Points
44
Update Interval: Based on heartbeat tag update.
Description:
Counts number of all values (inputs, outputs, triggered inputs) being sent to Historian before
exception processing occurs. This tag will update based on the the update rate of the
heartbeat tag and may report zero for update intervals where no data was sent to Historian. If
the value stops updating in Historian then this is an indication that the interface has stopped
collecting data.
Message Counter
ExDesc Keyword: [UI_MSGCOUNT]
Update Interval: Every 60 Seconds.
Description:
The Message Counter tag keeps track of the number of messages the interface has logged to
the pipc.log file since interface start-up. The value of this tag is used solely for ad-hoc
queries and diagnostics. It is a general rule-of-thumb that if the interface is logging a large
number of messages, there is probably a problem that should be investigated.
Output Rate
ExDesc Keyword: [UI_OUTPUTRATE]
Update Interval: Based on heartbeat tag update interval and each performance summary
interval.
Description:
Counts number of output tag events that are sent to Historian before exception processing.
Output tags update based on some event and cannot be scheduled for an update rate.
Therefore, the value of these tags will be updated at the same rate as the heartbeat tag and
will reset after the performance summary interval.
Note: If no output points are defined, the digital state value of “No Result” will be written
to the point.
Output Bad Value Rate
ExDesc Keyword: [UI_OUTPUTBVRATE]
Update Interval: Based on heartbeat tag update interval and each performance summary
interval.
