Description
Stores the communication status of the device 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 device station is disconnected.
1: In the CANopen function initialization sequence, the NMT state machine is in the
Operational state.
The value of the device station that does not support CANopen communications is fixed
to 0.
This value is stored by each module number of the device 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).

Each No. in the table represents a station No.
 is fixed to 0.
(Conditions)
• Stations that surpass the maximum station No are ignored.
Stores the driver communication cycle currently operating. (Unit: s)
Fixed to 0 when driver communication is disabled.
Stores the system reservation time in 'Driver communication cycle interval' (SW04C0).
(Unit: s)
Fixed to 0 when driver communication is disabled.
Stores the cyclic transmission time in 'Driver communication cycle interval' (SW04C0).
(Unit: s)
Fixed to 0 when driver communication is disabled.
Stores the transient transmission time in 'Driver communication cycle interval' (SW04C0).
(Unit: s)
Fixed to 0 when driver communication is disabled.
Stores the magnification of the basic communication cycle conversion based on 'Driver
communication cycle interval' (SW04C0).
Fixed to 0 when driver communication is disabled.
Stores the magnification of the multiple cycle setting (medium-speed) conversion based
on 'Driver communication cycle interval' (SW04C0).
Fixed to 0 when driver communication is disabled.
Stores the magnification of the multiple cycle setting (low-speed) conversion based on
'Driver communication cycle interval' (SW04C0).
Fixed to 0 when driver communication is disabled.
