To sum theĀ information up:
- For the economy device the acyclic traffic on the EtherCAT Network can get to high quite quick because of its limited computing power
- Master is getting confused because mailboxĀ telegrams need to get sent several times
- The warning itself can mostly be ignored as only single acyclic telegrams could get lost, that should not disturbĀ the application
Does this bring technical issues for your application or is it more a not nice to see? As the release cycle of the firmware is quite long for the old devices it could take some time to implement changes.
