Ignition 7.9.5 - isAlarmActiveFiltered - wildcards for relative tagpath

Ignition
1

Hi @KathyApplebaum,

We try to use the new expression in 7.9.5 isAlarmActiveFiltered

We have gateway tags inside an UDT with the following expression

Tag1 :

forceQuality(isAlarmActiveFiltered("..[.]/*_AH", "*", "*", 3, 3, 0, 1, 0),192)

Tag2 :

forceQuality(isAlarmActive("..[.]/*_AH","*"),192)

We have an active alarm with priority 3,
Tag1 = 0 instead of 1 as expected
Tag2 = 1

Can we use "…[.] " or these kinds of widcards for relative tagPaths in isAlarmActiveFiltered ???
It seem to be mandatory to have a path with an explicit tag provider (as for example “[default]”) in isAlarmActiveFiltered

Hey @mazeyrat,
The provider name is only required in the tagPath on gateway-scoped expressions, otherwise the function assumes the default provider.

The isAlarmActiveFiltered function uses the same tagPathParser that isAlarmActive uses, so wildcards should all work the same way . However, I think the syntax in your example is a bit off. If you’re specifying a provider, it should be the first item in the string.

So in your example it should be something like:

forceQuality(isAlarmActiveFiltered("[.]../*_AH", "*", "*", 3, 3, 0, 1, 0),192)

Yes @Michael.Stofan,

forceQuality(isAlarmActive("[.]../*_AH","*"),192)

is OK,

but is isAlarmActiveFiltered with same TagPath filter criteria of is NOK :frowning:

forceQuality(isAlarmActiveFiltered("[.]../*_AH", "*", "*", 3, 3, 0, 1, 0),192)

Hmm… Looks like something may not be working right then. Can you send me an example of one of your UDTs so we can test it out?

@Michael.Stofan
See attached an export of the UDT
Alarme and AlarmeMoyenne are OK
AlarmeHaute is not working.

Hi, I know this is an old converstation, but I have the same problem with realtive paths for isAlarmActiveFiltered in UDT´s. Did anyone of you find a solution for this?

We use with success expression like this (inside UDT on the tag /TS/STATUS)
(Ignition 7.9.12, I suppose OK with 7.9.6+ )

isAlarmActiveFiltered(replace("[default]{PathToTag}*","/TS/STATUS","/TA"), "", "", 3, 3, 0, 1, 0),

OK, Have you tried this script in 8.0.X? it doesn´t seem to work in 8.0

Expression has changed in Ignition 8, especially UDT parameter.

Example for 8 :

isAlarmActiveFiltered(concat("[default]",replace(concat({PathToTag},"*"),"/TS/STATUS","/TA")), "", "", 3, 3, 0, 1, 0),
