A state transition program that transitions to itself with no delays uses all CPU time that is at the SNL and lower priorities.
I do not recall if the Channel Access Client runs at a lower priority than the state notation engine.
I think that the vxStats gotten from vxWorks are computed in the idle task. That would mean that it would never run.
The better tool for finding this problem is to run the SNL diagnostic, seqShow "state set name".
The current state and the previous state would show the two states (or one if it is to itself), in the infinite loop. And the time in this state will always be zero - or very close to zero. |
