CP2E CPU Unit Software User’s Manual(W614)
Data that has been created using the CX-Programmer or CX-Integrator is transferred to the internal
memory in the CPU Unit as shown in the following diagram.
The CPU Unit will access the backup memory in the following process.
• The program, parameters, comments, program index or symbol table are transferred from the CX-
Programmer and CX-Integrator.
• The program is changed during online editing.
• DM backup is operated by the Auxiliary Area.
During these processes, BKUP LED will light, indicating that the CPU Unit is being backed up.
There are the following limitations during backup.
• The operation mode cannot be switched from PROGRAM mode to MONITOR/RUN mode.
• If the power supply is interrupted when the program or parameters are being transferred or backed
up, memory error may occur when the power supply is turned ON next time.
• If the power supply is interrupted when the DM area is being backed up, the reading of backed up DM
area will fail when the power supply is turned ON next time.
