SpectroWATCH Event Variable 7 used in a custom Event Table is not working as expected.

Issue/Introduction

We have a SpectroWatch configured on a model where the threshold is set on an enumerated Integer list attribute on the device. For example:

0 = bad
1 = good
2 = notpresent

The threshold of the watch is configured if the value is not equal to 1, the assert a custom event.

A custom Event Table was created with the following:

0 bad
1 good
2 notpresent

In the Event Format file, we add the event table to convert the numeric value to the text value in the Event Table.

{T mytable 7}

When the threshold is exceeded or matched in a SpectroWatch, the SpectroWatch passes the value that value to the event as Event Variable 7.

We are expecting to see the text value in the associated event. However, no value is seen.

 

Environment

Version: Any
Component: SpectroWatch

Cause

The SpectroWatch sends the value of Event Variable 7 to the event as a text string. Text and octet string Event Variables cannot be used in an Event Table.

Reference the "About Event Table Files" section of the documentation for more information.

Resolution

You can use an Event Condition rule on the event generated from the threshold exceeded. 

If text "0" then event 1 stating "bad"
If text "2" then event 2 stating "not present".

Then have the reset event clear alarms asserted by events 1 and 2.

Please reference the "Working with Event Rules" section of the documentation for more information on configuring an Event Condition rule.
