I'm new with WAGO PLC and I want to conect an absolute encoder with CAN-open.
The WAGO said that the 750-837 can't be used to create a CAN newtwork, and if i want to connect any device to my PLC i have to do the mapping of the network manually.
I searched everyware for an example but nothing clear.
I know that wago has a libraty CIA405 but my encoder use CIA406
Can someone give me some advices? I don't know where to look any more.
Thanks in advanced,
Florin Anghel
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I don't know the WAGO line but something sounds funny. You obviously have a CAN card? But what I think you are trying to say is the WAGO PLC is not capable of being a CANopen Master ("create a CAN newtwork"). Since you make mention of can access then they must give you CAN Layer 2 function blocks like CAN_Receive and CAN_Transmit? If so then the "mapping" of the encoder position data is in COBID 180xh+ nodeID of the encoder. If you need to write SDO to configure the encoder than you need to do this by hand if I understand your stituation correctly. Also you need to Master the encoder. you need commands like NMT "Start" to set the encoder into the operational state. Please add more detail so I can help further. Are you sure it doesn't have CANopen Master functionality? Maybe you only need to add the eds file?
