How to reset the CAN open communication?

Recommended Posts

Hi,
We have a application with CAN open network and an UniStream PLC. Most time won't start the CAN communication. We fixed it to restart only the PLC, in that period the CAN unit is stil.

I search a software command in the UniStream to reset the CAN communication.
Who can help me?

thanks a lot

Hi

My friend and I have the same problem and I can not solve it.

I made a small test application but I do not succeed, If you managed to solve the problem please let me know, how !!!

I attach my small application for the MURR cube 20s , but I believe that all devices do the same. 

And please tell me if I have any omissions

Hello,

Sometimes the CAN device might "wake up" only after the PLC.

If you are using the "auto start" - try to uncheck it as captured and send the start using NMT command to start the CANopen slave after a delay.
