2 Common Specifications of IAG Behavior of Each Device and Data Flow IAGs write data to each device and execute a restore by using each device’s function as shown in the figure below. Executing Restore of NJ/NX-series CPU Units 2-1 Function The IAGs read out data of the NJ/NX-series CPU Unit from the USB flash drive or the latest backup in the SD Memory Card on the NA-series Programmable Terminal, and then write it to the SD Memory Card in the NJ/NX-series CPU Unit. They execute a restore by using the SD Memory Card backup function of the NJ/NX-series CPU Unit.
After restoring the NJ/NX-series CPU Unit successfully by using the IAG, cycle the power supply to the Controller and all of the EtherCAT slaves. For details, refer to the restore section of the SD Memory Card backup function in the NJ/NX-series CPU Unit Software User’s Manual (Cat. No. W501) .
