No. Name Description
SW0470 NMT state Stores the communication status of the slave station that supports CANopen
to machine communications.
SW047F 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.
SW04A0 Time Stores the time synchronization method.
synchronization 0: IEEE1588
method 1: IEEE802.1AS
SW04B0 Station time Stores the time synchronization status for each station. (station No.1 to 120)
to synchronization 0: Time asynchronous station
SW04B7 status 1: Time synchronized station
For time synchronized stations, the time synchronization method can be found in
'Time synchronization method' (SW04A0).
