CANOpen communications problem using TMSCO1

Hello everyone,


I am using TMSCO1 module to be able to communicate through CAN with other devices. The thing is the bus is not working and apparently I don't know why. Checking online with the M262 PLC I can see those red triangles but I haven't been able to find on the internet what those triangles mean because the exclamation mark is changing its colour every now and then.


Also I did check the errors in the logs and this is what I got (Look to the pictures)


Could anyone please help me providing any documentation or maybe source of the problem?


Thanks in advance
