Hello,
I use the card 750-658 with WagoAppCanLayer2 library.
It is working!
Sometime, when i power on the PLC, the communication doesn’t work. I have the message of FbCANL2OPEN with diReturn “CanDeviceUsLocked”.
I use FbCANL2CLOSE or FbCANL2RESET without results 
I need to reboot PLC to restart communication.
Do u have idea?
