Composite function blocks
If you wish to use the same logic function several times, you can combine and save it in a composite
function block.
How to create a composite function block:
1. Create your logic using "normal" input sockets and output sockets and check the function of the
logic using the simulation.
2. Copy the logic and replace the input sockets and output sockets with the function blocks FB IN
and FB OUT of the same data type.
3. Enter the following parameters for function blocks FB IN and FB OUT:
o Short description:
One or more letters that are displayed on the input and output of the function block.
o Full description:
Name of the function block, can be seen on moving over it with the mouse.
o Index:
The number of the input/output; this must be unique.
