I'm not sure if this what you are looking for but in the past I have used "CAA Can Low Level Extern" (CL2) to send and read messages without using a manager.
I need the CanOpen manager for all my CanOpen nodes. But I also need to send and recieve some raw can messages on the same interface.
Is it possible to have a CanOpen Manager and to send raw CAN messages simultaneously?
As i said my PLC manufacturer states in the manual that only the library CAA CiA 405, 18.104.22.168 is supported for CAN and I dont see any RAW CAN FBs in that library. So I dont know if I can use the CAA Can Low Level Extern?
