Set the operation mode of the network module.
The set parameters take effect when the switch setting of the network module is set to
"online".
For the switch setting of each network module, refer to Section 4.2.
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 as follows:
Cyclic data (LY/LB/LW)
Transient data
When a programmable controller is being added to the system as shown in the figure
below, the debugging can be executed without stopping the system 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.
GX Developer
Data receiving
enabled
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 of 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 of 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 of 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 of 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.
Set the operation mode of the network module mounted on system B in the mode
selection of the redundant settings (system B).
For details of the redundant settings, refer to Section 7.10.4.
