Description
Stores the communication status of the slave station that supports CANopen
communications.
0: In the CANopen function initialization sequence, the NMT state machine is not
yet in the Operational state or the slave station is disconnected.
1: In the CANopen function initialization sequence, the NMT state machine is in
the Operational state.
The value of the slave station that does not support CANopen communications is
fixed to 0.
This value is stored by each module number of the slave stations set in the
network configuration setting.
Stores the synchronization method.
0: IEEE 1588
1: IEEE 802.1AS
Stores the time synchronization status of each station. (Station number: 1 to 120)
0: Station that does not perform time synchronization
1: Station that performs time synchronization
The time synchronization method can be checked in 'Time synchronization
method' (SW04A0).
