SpectroWATCH: Need to compare previous value to current and alarm if previous value is greater

[Karen Brooks]

All,

I'm not sure is this is possible solely within SpectroWATCH (10.4.2). Below in a nutshell

I have an OID (Integer data type) I need to query. I've added that as an attribute.

1. get and store value of OID as a previous value
2. get current value of same OID
3. Compare - if previous value is > than current value, generate an alarm.
4. If current value is > than previous, clear the alarm.

I've tried with two and three watches to accomplish this.

The issue I'm running into is that I cannot set a proper threshold.  I can set the threshold where previous is greater than current, however the reset is perhaps what's problematic.  I'm not sure since I get a user syntax error and cannot save.

I did see an older tip on using an Event Procedure for a similar requirement, but hoping I won't need to do this.

Any and all ideas are welcome.

There are 3 watches at this point:

W1: Contains the previous value in expression:  DELTA(cEigrpNbrCount.#)
        Evaluate by Poll
        No Threshold

W2:  Contains current value in expression:  cEigrpNbrCount.#
         Evaluate by Poll
         No Threshold

W3: Contains W1 in expression:  PRU_Previous_cEigrpNbrCount.#
        Evaluate by Poll
        Threshold (See image in previous post) - NO Alarm configured to generate yet
