Additional Information
• Make sure that the communications cables between the master and slaves are connected
correctly before you perform this operation. You cannot get the serial numbers of the slaves
unless the connections are correct.
• You cannot get the serial numbers of the slaves if there is a slave in the actual network con-
figuration for which the node address is not set or if the same address is set for more than
one slave in the actual network configuration. Make sure that node addresses are set correct-
ly for the slaves in the actual network configuration before you perform this operation.
• You cannot get the serial numbers of the slaves unless the Compare and Merge with Actual
Network Configuration Dialog Box shows that the entire slave configurations agree. Make
sure that the Compare and Merge with Actual Network Configuration Dialog Box shows
that the entire slave configurations agree before you perform this operation.
However, you can get the serial numbers of the slaves even if the entire slave configurations
do not agree if there are slaves in the Sysmac Studio settings that are disabled.
• If you get the serial numbers of the slaves when there are disabled slaves that do not exist in
the actual network configuration, the serial numbers of the disabled slaves will be cleared to
0x00000000 in the settings on the Sysmac Studio.
If the disabled slaves exist in the actual network configuration, the serial numbers of the
slaves in the actual network configuration are saved in the settings on the Sysmac Studio.
• Any serial numbers that are set for slaves in the settings on the Sysmac Studio are overwrit-
ten when the serial numbers are obtained from the actual network configuration. Make sure
that it is OK to overwrite the serial numbers on the Sysmac Studio before you perform this
operation.
• When you get the serial numbers from the slaves on the actual network configuration, the
synchronization between the Sysmac Studio and the Controller is lost. Synchronize the Sys-
mac Studio and Controller before you perform any online operations for the slaves. Refer to
the
Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for information on synchro-
nization.
