Emergency object
To inform the other participants at the CANopen bus of internal device
errors or CAN-Bus errors, the CANopen bus coupler supports the
emergency object. It is provided with a high priority and delivers important
information about the state of the device and the network.
Note!
It is highly recommended to analyze the emergency objects - they are an
important source of information!
The emergency telegram has always a length of 8Byte. It contains firstly
the 2byte error code, then the 1byte error register and finally the additional
code of 5byte length.
