Set the operation mode of the network module.
The mode selection with this parameter becomes valid when the mode setting switch
of the network module is set to 0 or 4.
This mode performs normal operations (the station returns to the network).
Starts data communication at startup and executes automatic return operation. etc.
This mode places the online station in the send stop status.
The station is recognized as a normal station from other stations and data
communication is performed in the following manner:
Cyclic data (LY/LB/LW)
Transient data
When a programmable controller is being added to the existing system as shown in
the figure below, the debugging can be executed without stopping the network system
in operation. When the debugging is completed, cancel the debug mode to execute
data linking. This function is convenient when performing the system expansion while
running the system.

This mode stops operations (disconnecting the station).
Baton pass and data communication with other stations are not executed.
This mode is to select the hardware test operation that checks the connection status
and the optical fiber cables on the forward loop side.
For details on how to conduct the hardware test, refer to Section 4.7.2.
This mode is to select the hardware test operation that checks the connection status
and the optical fiber cable on the reverse loop side.
For details on how to conduct the hardware test, refer to Section 4.7.2.
This mode selects the station to execute the hardware test for checking a line between
two stations.
For details on how to conduct the station-to-station test refer to Section 4.7.1.
This mode selects the station on which the hardware test for checking a line between
two stations is executed.
For details on how to conduct the station-to-station test refer to Section 4.7.1.
REMARKS
The mode set in the network parameters for the redundant system must be the
same as the operation mode of the network module mounted on system A.
