only 1 task ?!
since a long time I updated the Mervis IDE version and the OS on the respective Unipi1.1's.
I had 3-5 tasks per Unipi in my solution which worked well, but now after the update the IDE pops an error with having more than 1 task per PLC.
Is that intended or a bug?!
the functionality has changed, and now you cannot define more than one task. But you can define more programs to run inside a single task.
