Mathematical Expressions

Mathematical expressions can be entered algebraically into program code to perform processing on measurements, to be used for logical evaluation, or to be used in place of some parameters.

As an example of Measurement Processing, to convert a thermocouple measurement from degrees Celsius to degrees Fahrenheit, you could use the following expression:

TCTempF=TCTemp(1)*1.8+32

Logical Evaluation expressions could be used to determine the flow of a program:

If TCTemp(1) > 100 Then

Call Subroutine1

Else

'enter code for main program

EndIf

Many parameters will allow the entry of expressions. In the following example, the DataTable will be triggered, and therefore data stored, if TCTemp(1)>100.

DataTable(TempTable, TCTemp(1)>100, 5000)
