(4) Completion of module initialization (02C6H: 1 word)
This register indicates the completion of initializing after switching power on or by a
reset request.
"1": Initializing completed
Other than "1": Initialization under way
(5) Node error counter (02BFH to 02C5H: 7 words)
The CAN controller used in the DN611 has a function of notifying error state changes
of the local station (error active ↔ error passive ↔ busoff) based on the frequency of
transmission error occurrence.
The CAN controller also has a function of notifying the DN611 of an overrun error,
which occurs if the DN611 fails to take the data sent from slave devices because the
CAN controller processing of the received data could not follow the data input speed.
That is, if an overrun error occurs in the DN611, it means that the DN611 has failed to
take the data from the slave devices. The DN611 maintains the current error state
and a history of error state changes since the start of communication. This register
shows a history of error state changes since the start of communication and the total
number of transmissions and receptions.
