Hi, I am new to this forum and have used PI for a few months up to this point. I am trying to make a process book for operators that is as my boss says, "like a videogame". He wants a graph showing production rate and when the cvalue fo the tag reaches certain points, text to pop saying "level 1" or something like that. Then when the next level is reached the previous text to dissapear and new text to appear.

Also, is there a way to show a static 12 hour (1 work shift) time range, and when that 12 hours is up, have the time range update to show the next 12 hour block? I'm pretty sure both of these things are possible, just not sure how to do it. Thank you for the help!

Kyle

Hi Kyle,

Welcome to the forum.

For your first point, you have a couple of options.
First would be to create a digital/string Performance Equation that simply sets the value to your various levels depending on your input value.
e.g. if 'sinusoid' > 50 then "Level 1" else "Not good enough"
Then you simply just display the above PE tag on your display.

Alternatively, you could place a series of Text symbols on your display and just MultiState them based on your input tag. Have a Text symbol that says "Level 1" with MultiState containing 2 states, State 1 "0 -> 99.99" No colour for the text. State 2 "100 --> ..." Colour for the text. etc

If you want to set 12 hour blocks, you can set it for the Display using the SetTimeRange method. e.g. ThisDisplay.SetTimeRange("*-12h","*")

Hope this helps...

Thanks, I forgot you could Multistate text to show no color. I'm still a little confused on the time thing though. Is the SetTimeRange a function I input under ThisDisplay in VBA? If so, what is the actual code to do that and will this then show a constant 12 hour block then once this is up move onto the next twelve hours?

You'll have to apply the method using VBA.

Code:
Private Sub TrendConfig()

Dim trTrend As Trend
Dim strStart As String
Dim strEnd As String

strStart = "2/18/10 12:00 PM"
strEnd = "2/18/10 2:00 PM"

Set trTrend = ThisDisplay.Trend1
Call trTrend.SetTimeRange(strStart, strEnd)

Set trTrend = Nothing
End Sub


You will have to find a way for VBA to look at the time and pick the correct time ranges. The trend will also not automatically update with new data with the start and end time defined as such. There has to be a work around. I'm playing with it though.
