Configuration Information
You must download the network configuration information in the project from the Sysmac Studio to the
NJ/NX-series CPU Unit. Use the synchronize operation to download the network configuration informa-
tion. Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for information on syn-
chronization.
After you transfer the user program, the CPU Unit is restarted and communications with the Eth-
erCAT slaves are cut off. During that period, the slave outputs behave according to the slave
specifications.
The time that communications are cut off depends on the EtherCAT network configuration.
Before you transfer the user program, confirm that the system will not be adversely affected.
