Isakovic Posted August 6, 2020 Report Share Posted August 6, 2020 I'll explain the problem I had, maybe it helps somebody. I have several controllers that need to have synchronized RTC, and there was a problem that time update didn't work properly. After some troubleshooting I found that "Status" variables need to be defined in order for function blocks to work. This does not work (usually): This does work: Both cases compile the same without error or warning.
