In IGSS it is possible to define calculations and show the results on standard process diagrams. Without any programming it will be possible to combine the object values available. The following calculation elements will be available:
-
All simple operators will be supported: +, -, *, /
-
Boolean operators will be supported. E.g. (x > 1.5) will result in either 0.0 or 1.0
-
It will be possible to use other object values as arguments in calculations. E.g. Obj1.Value = Obj1.Value + 2 * Obj2.SetPoint
-
Values can be calculated based on historical object values
-
Calculations can be executed on object changes in the calculation expression or with a fixed interval (timer)
-
Preconditions for executing a calculation can be specified (IF statements).
The calculation feature is available for all I/O points of analog and digital objects. It is found on the "Calculation" page of the object properties dialog box.
