Additional Information
The device variables are na med a utomatically from a combinati on of the device names and
the port names. For s lave units, the de fault dev ic e nam es ar e "E" fol lowed by a ser ial nu mber
that starts from 001. For N X Units, the default device names are " N" followed by a serial
number that starts from 1.
Additional Information
In this document, device var iab les are automatically named for a un it ( a slave).
Device variables can also be manually named for ports.

Transferring the Project Data 7.5.2.
Connect online with Sysm ac St udio and transfer the project data to Controller.
When you transfer a user program, configuration data, s et up dat a, device
variables, or values in me mory used for CJ-series Units from Sysmac Studi o,
the devices or machines may perform unexpected operation r egardless of the
operating mode of CPU Unit.
Always confirm safety at the destination node before you transfer the project
data.
After you transfer the proj ec t dat a, CP U Unit restarts, and communicat io ns w ith
the slaves is cut off. During the period, the slave output s behave according to
the slave settings. The t ime that communications is cut off depends on the
EtherCAT network configuration.
Before you transfer the pr oject data, confirm that the slave settin gs w il l not
adversely affect t he device.
The Slave Unit will be reset after performing the synchroniz at ion i n st ep 7 and
subsequent steps, and th e device may perform unexpected operation.
Always confirm safety bef or e you perform the synchronization.
