Application Question

One thing I am looking to do is display a "Time Remaining" line.
Unfortunately this would require two tags to co-exist on the same line at
the same time. Say XX is the minutes remaining and YY is the seconds
remaining in a particular process. I'd like to be able to have one line
read:

Time Remaining XX:YY

Is there any way to do this?

Yes, you can do it

There is no way to do what you need in exactly the way you describe. However you can possibly tweak it a bit your PLC program to produce a similar result.

Imagine you have a single INT tag, let's call it 'time' that stores minutes and seconds in a way that you have time = minutes*100 + seconds (you must do it in the PLC).

Now you can display the remaining time in ScadaMobile by adding a divide-by-100 scale attribute and a format attribute to the 'time' tag like this

scale := {0,100,0,1} ; format := "05.2" ;

This will display values in the form XX.YY with leading zeroes if XX is less than two digits, for example 01.59 or 00.01 or 15.38

I hope you can deal with it in that way.
