8.3.1.2 Establish a communication for b maXX PLC
After booting the option module CANopen slave tries to establish the communication with the
CANopen network. If the module cannot establish the communication, the red LED H2 blinks:
Figure 12: Error - no communication b maXX PLC
As soon as a few valid Data frames have been send/received, the red LED H2 turns off. This
means, that although there is a valid communication the LED still can blink.
If the module has established the communication, but if the communication is faulty, you can
only recognize the errors by using a bus monitor of the master. In the following you will find the
most common errors.
