8 Math and Condition Channels

This chapter describes how to create a Math or Condition Channel.

8.1 Math Channels

Math channel

– Arithmetic and logical operations on up to 4 measurement channel(s)

– Numerical result

– Result can be used as input source for various display elements (numeric elements,

alarms, Bargraphs) and further calculations in the whole RaceCon project

Conditional function

– Arithmetic and logical operations on one or more measurement channel(s)

– If-Else structure with reset

– Numerical result

– Result can be used as input source for various display elements (numeric elements,

alarms, Bargraphs) and further calculations in the whole RaceCon project

All math channels can be used globally in the whole MSI 60 project.

8.1.1 Creating a new Math Channel

Follow the steps shown in the screenshots.

a) Double-click on ‘Math Channels’ in Project Tree.
b) Click on ‘Add channel’.

The ‘create/edit math channel’ window appears.
