Go offline, and then assign device variables, set the axis parameters, set up the tasks, and set
the master and slave parameters.
Additional Information
• Make sure that the communications cables between the master and slaves are connected cor-
rectly before you perform this operation. The Compare and Merge with Actual Network Config-
uration Dialog Box is not displayed if the connections are not correct.
• The Compare and Merge with Actual Network Configuration Dialog Box is not displayed if
there is a slave in the actual network configuration 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.
• The Compare and Merge with Actual Network Configuration Dialog Box is not displayed if an
EtherCAT Frame Not Received error occurs. Remove the cause of the error and perform the
compare and merge operation. Refer to 9-2-1 Error Table for the cause of the error.
• Even if you have previously set them on the Sysmac Studio, the following configuration and
settings are discarded when you automatically create the network configuration on the Sys-
mac Studio based on the actual network configuration: network configuration, master settings,
and any slave settings (including enable settings, PDO map settings, setting parameter set-
tings, backup parameter settings, device variable assignments in the I/O map, slave assign-
ments to Axes Variables registered in the axis settings, and master settings to control slaves
that are registered in the task setup). To merge the actual network configuration information
without losing the current settings in the Sysmac Studio, use the compare and merge opera-
tion to create the network configuration. Refer to 5-5-1 Comparing and Merging with the Actual
Network Configuration from the Sysmac Studio for information on the operation to compare
and merge with the actual network configuration on the Sysmac Studio.
• When the compare and merge operation is performed, the synchronization between the Sys-
mac 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 Oper-
ation Manual (Cat. No. W504) for information on synchronization.
