Remedied from:
ECS axis module V7.1,
all versions (ECSxS, ECSxP, ECSxM, ECSxA)
Behaviour of new version?
In the previous version the reaction on the exception handling 'task overrun' (=warning) was not entered in the history buffer. If the reaction is configured correspondingly, the correct entry will now be executed.
In general: In case of a task overrun the cause is first to be eliminated, the tasks have to be blocked with PLC reset (C2108 = 3), and then the TRIP has to be reset with Trip reset (C0043 = 0).
Which products are affected?
ECS axis module (B-SW) V7.0,
all versions (ECSxS, ECSxP, ECSxM, ECSxA)
What happens?
In case of a task overrun the exception handling set in DDS (warning or trip) is processed, the PLC is stopped and the affected tasks are blocked.
The exception handling 'warning' does, however, not lead to an entry in C168/1 = 2202. (fault memory)
When does the problem occur?
With each task overrun where reaction = warning has been set.
Possible diagnostics?
Control of the fault memory
Short-term measures / recommendations?
None.
Evaluation:
There is no need to intervene, as an entry into the history buffer has not been executed and the function of the exception handling is not affected.
