Hello,
A customer is using ctrlX CORE as as gateway between his WebIQ application and Allen Bradley Micrologix PLC. This involves Node Red, which has a pallet to support reading/writing tags in Micrologix. The KVD app is used to create the nodes on the Data Layer which can be accessed by Node Red and WebIQ for data exchange. In general the solution is working, but after some runtime the KVD nodes dissapear and data exchange is no longer working. They have observed 45 min - 5hr in between failures. After a reboot the nodes appear and everything is working again. I attached a system report. In logbook.csv I notice entries like this:
[kvd] license not found;;;snap.rexroth-kvd.kvd.service
[kvd] releasing license ...;;;snap.rexroth-kvd.kvd.service
Stopped Service for snap application rexroth-kvd.kvd
But this CORE has a permanent KVD license. This might be the same issue reported here.
Best regards,
Brian
