8.8.6 Changes in the parameters when the submaster station is used
This section describes how to change the parameters when the submaster function is used.
(1) When the setting is configured in the network parameter window of GX Works2
When the setting is configured in the network parameter window of GX Works2, the CPU module needs to be
reset.
In addition, when the total stations and network configuration settings have been set in the submaster station, it is
recommended to change the parameters in the order of the submaster operating station and the master operating
station.
The following are the procedure of changing parameters when a submaster station is operating as a
submaster operating station.
1. Write the updated parameters to the submaster station.
2. Reset the CPU module on the submaster station or power off and on the system.
Because the parameters in the submaster station are different from those in the master station, a
parameter error occurs in the submaster station. However, go to the step 3.
3. Stop data link in all the stations.
4. Write the updated parameters to the master station.
5. Reset the CPU module on the master station or power off and on the system.
6. Because data link is stopped, an error occurs in the master station. However, go to the step 7.
The error in the submaster station is cleared.
7. Restart data link in all the stations.
When no setting is configured in the total stations and network configuration settings in the submaster station,
follow the steps 3 to 7 above.
(2) When the parameters have been set using the CCPASET instruction
When the parameters have been set using the CCPASET instruction, the CPU module does not need to be reset.
In addition, when the settings have been configured in the total stations and network configuration settings, it is
recommended to change the parameters of the submaster station before the master station. The time length of a
data link stop can be shortened.
1. Execute the CCPASET instruction in the submaster station to change the parameter settings.
Because the parameters in the submaster station are different from those in the master station, a
parameter error occurs in the submaster station. However, go to the step 2.
2. Stop data link in all the stations.
3. Execute the CCPASET instruction in the master station to change the parameter settings.
The error in the submaster station is cleared.
4. Restart data link in all the stations.
When no setting is configured in the total stations and network configuration settings in the submaster station,
follow the steps 2 to 4 above.
