Node guarding event cannot be reset (remedied from B-SW V8.0)
Remedied from:
ECS axis module V8.0
Behaviour of new version?
An activated node guarding event (C0168 = 260) can be reset. In response to a node guarding telegram the ECS axis module changes the toggle bit included correctly.
Which products are affected?
EPL-10200 (Drive PLC V7.1 and lower)
EVS93xxEI (Servo PLC V7.2 and lower)
EVS93xxET (Servo PLC with technology function V7.2 and lower)
ECS axis module ECSxx series, operating software V7.4 and lower
What happens?
In response to a node guarding telegram the PLC target system does not change the toggle bit accordingly. An activated node guarding event (C0168 = 260) can only be reset by mains switching.
When does the problem occur?
The response described occur may occur in case of a high bus load on the system bus if the PLC target system has been configured as Slave with node guarding (C0352 = 4).
Possible diagnostics?
None.
Short-term measures/recommendations?
None.
Evaluation:
The function restriction may occur in case of a high bus load on the system bus if the PLC target system has been configured as Slave with node guarding.
