1-1 CP1E Overview
The SYSMAC CP1E Programmable Controller is a package-type PLC made by OMRON that i s
designed for easy application. The CP1E includes E-type CPU Units (basic models) for standard control
operations using basic, movement, arithmetic, and comparison instructions, and N/NA-type CPU Units
(application models) that supports connections to Programmable Terminals, Inverters, and Servo Drives.
Precautions for Correct UsePrecautions for Correct Use
For CP1E CPU Units, the following I/O memory area will be unstable after a power interruption.
• DM Area (D) (excluding words backed up to the EEPROM using the DM function)
• Holding Area (H)
• Counter Present Values and Completion Flags (C)
• Auxiliary Area related to clock functions(A)
Mount the CP1W-BAT01 Battery (sold separately) to an N/NA-type CPU Unit if data in the above
areas need to be retained after a power interruption. A Battery cannot be mounted to an E-type
CPU Unit.
