NMT as response to remote request only suppressed at the master (remedied from B-SW V7.4, ECSxE from V3.0)

Remedied from:
ECS power supply module ECSxE series, operating software V3.0
as well as:
ECSxA (ECS axis module 'Application' as of version 7.4) and standard applications 'Speed&Torque', 'Posi&Shaft' and 'Motion'

Behaviour of new version?
The ECS axis module principally does not send a telegram in response to a remote request with identifier 0.



Which products are affected?
ECS power supply module ECSxE series, operating software V2.3
ECS axis module, operating software ≤ V6.6
EVS93xx-EI (Servo PLC V6.0)
EVS93xx-ET (Servo PLC V6.0 with technology function)
EPL-10200 (Drive PLC V6.0)

What happens?
In response to a remote request with identifier 0 the controller returns a NMT (Network Managment Telegram) containing the following data 0xFF 0xFF.

When does the problem occur?
If the controller is configured as master the response to a remote request with Id 0 is suppressed.

Possible diagnostics?
CAN analysis.

Short-term measures/recommendations?
None.

Evaluation:
The NMT containing data like 0xFF 0xFF is not defined in CAN Open. Devices which are CAN Open conform reject this telegram.
