Alarm Condition for Boolean Trigger Item in Alarm Manager WebIQ

[teknofluida]

Alarm condition for Boolean type trigger item didn't work. If I chose TRUE then it's always TRUE even the trigger item is FALSE. As an example I use variable boolean for TempMaxWarn from ctrlX PLC that when the temp is over 55, then the variable is TRUE. But in the alarm info it's still sending warning even the temp is under 55. What's the solution for boolean type trigger that when the trigger is TRUE then alarm true and when the trigger is FALSE then it's not sending alarm to alarm table/info? Thank you

When choosing "TRUE (always active)" as an alarm trigger it will always be active regardless of the specified item, because that is what "always active" means. The same applies to "FALSE (always active)", just vice versa:

For boolean values simply check for "equal 1" or "equal 0".

For raising an alarm when a numeric item is e.g. >55 use "greather than 55".

Are we using decimal? Because when I tried using binary, an error pop-up appeared.

This is all documented in the manual:
"The argument of the alarm condition can be specified either decimal, hexa-decimal (i.e. 0x03) or binary (i.b. 0b011). The number format must be chosen in the intended select-box (right to the Alarm Condition) and using the appropriate number format."

So using the default "decimal" is the way to go - unless you want to use "binary" which simply is binary notation of the number or "hex" which is the hexadecimal notation. But there's no need to make it more complex than you need.
