1-1 CP1E Overview
The SYSMAC CP1E Programmable Controller is a package-type PLC made by OMRON that is
designed for easy application. The CP1E includes E-type CPU Units (basic models) for standard con-
trol operations using basic, movement, arithmetic, and comparison instructions, and N-type CPU Units
(application models) that supports connections to Programmable Terminals, Inverters, and Servo
Drives.
