5 Setting Up EtherCAT Communications with the Sysmac Studio
Additional Information
• Make sure that the communications cables between the master and slaves are connected cor-
rectly 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 config-
uration 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 correctly 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 net-
work 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 overwritten
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 syn-
chronization between the Sysmac Studio and the Controller is lost. Synchronize the Sysmac
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 synchroniza-
tion.
