the plant I am supporting uses a siemens graph function to do some of the step procedures. in several steps it waits for the step to execute for a say 200ms before it will advance. But at times I have found that while waiting at the step the time associated with that step does not advance(stays at whatever its last value was. I fixed it with external timers but has anyone seen this before?
