Hey guys,
I used to have a PLC and a HMI from ifm. I programmed both of them in v2.3 and used network variables over CAN.
We switched to another PLC and HMI from TTControl. The PLC can be programmed in v2.3 and the HMI with v3. I looked up network variables in v3 and it seems to be supported, but only over UDP. When I want to use CAN it gives me a warning stating: Network protocol not defined in device description.
I can't seem to find the settings for adding CAN as a network protocol. Has someone ever used CAN for communication between codesys v2 and v3? I tried adding a canopen slave in v3, then exporting it as an eds file and then importing it in v2.3. It didn't seem to work (everything stayed 0).
Also, after importing the EDS file, i could not communicate with my encoder on the same CAN.
