Wonderware intouch histrend show comments

Hi,

Im trying to dynamically show comments for the selected tags in the history trend in wonderware intouch. Im using the following script:

Condition script:
Trendind2.Name <> HTGetPenName("HistTrend", HistTrend.UpdateCount,2)

While true:
DIM x2 AS MESSAGE; x2= HTGetPenName("HistTrend", HistTrend.UpdateCount,2); trendind2.Name = x2; {trendind2 is an indirect analog tag}

This method is working correctly when i select io real tags in the history trend.

Problem is that when I select an io discrete tag in the histrend it will not show the comment for this.

Does anyone have a solution for this?

Best regards

Is the discrete tag configured for historical logging?

Yes, all discrete and real tags in the system er configured for historical logging.

The discrete tag is working in the trend, but when selected my script will not show any text for it. Probably because my script is taking a indirect analog.

Sounds like you the identified the issue, now u need to work on a solution...

Yes, i have a solution for it.

The solution is to have two condition scripts, one for ioreal and one for iodiscrete.
This will give 16 condition scripts since there are 8 pen trend in history trend.

I want to know if there is an easier way to solve this that combine both analog and digital tags?
