Transaction Group Execution

How are transaction groups executed if they run at the same update rate.
Do they run asynchronous or in sequence listed. Reason I am asking this , I thing an install we have is having timing issues and this group has the issue.
The last two groups run at the same rate, look at the same trigger, but the last group resets the trigger on completion.
If groups run in sequence I should be ok, but if they ran at the same time, I may have a timing problem.


It’s definitely asynchronous. If you need the groups to depend on each other, you either need to adjust the timing, or use something like a db/memory tag to coordinate them. Unfortunately there isn’t a way to make execution of one group directly dependent on another.
