TwinCat 3- Program POU- Execution order

kalabdel said:

Hello gentlemen,


If I have more than one Program POU assigned to the same PlcTask, how do I changed the priority of which program executes first?

The only way I can do that is in the project tree; I delete all the programs and then add them by order of first priority. I thought, there was a dialogue box that lists the Program POUs and I can move them up and down the list, like in CodeSys.


Thanks

What is the reason for multiple calls from the task - you can also call other programs from a program and then it is just a matter of order you write the calls in.

There are some other supposedly IEC-61131-compliant software packages that do not allow calling POUs from other POUs. Arranging multiple POUs within a task is the only way to control the order of execution.

Might be, but that is not Twincat 3 as mentioned in the title

Thank you everyone.
@Lare, that's what I've been doing and was surprised that there is no way to move them up or down either in the project tree or in a dialog box as in vanilla CodeSys.


This all came about when while working with TcUnit and keeping it the test suite separate from the development code being tested.
All the suggestions here would work just fine I think.


Thanks

I don't get what are you looking for. When you run unit tests, why would you run anything else than unit tests?
