8.3.2.2 Establish a communication for b maXX controller
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 15: Error - no communication b maXX controller
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.
