CoDeSys V3 – Quick Start 3/6

Declaration of variables

In our example we want to declare the input and output variables of our application in a global variable list. If we click on the application icon with our right mouse button and then choose ‘Add Object’, we can add different objects to our application. We will select the ‘Global Variable List’ and will call it “SimulationSignals“.

The required input variables are DoorOpen, DoorClosed, DriveOverload (for the sensors) and Actuation for the control button. Our output variables are DoorUp and DoorDown for the drive and Lighting for the lighting of the drive.

All I/O variables are Boolean variables.
