FBD variables

All variable symbols and constant expressions are entered in FBD"Function block diagram" A function block diagram describes a function between input variables and output variables. A function is described as a set of elementary blocks diagrams using small boxes.

1. Press the following button in the FBD toolbar to insert a variable tag:

   Insert variable: In this mode, the mouse is used for inserting variable tags. Click in the diagram and drag the new variable to the desired position.

2. Double-click on a variable tag to open the variable selection box
3. Either select the symbol of the desired variable or enter a constant expression.

   Variables tags must then be linked to other objects such as block inputs and outputs using connection lines.

4. You can resize a variable box vertically in order to display, together with the variable name, its tag (short comment text), its description text, plus its I/O location if the variable is mapped to an I/O channel.

The variable name is always displayed at the bottom of the rectangle:
