About this Manual:
This manual describes installation and operation of the CP-series Programmable Controllers (PLCs)
and includes the sections described below. The CP Series provides advanced package-type PLCs
based on OMRON’s advanced control technologies and vast experience in automated control.
Please read this manual carefully and be sure you understand the information provided before
attempting to install or operate a CP-series PLC. Be sure to read the precautions provided in the fol-
lowing section.
This manual is intended for first-time users of the SYSMAC CP series. The basic use of the series is
explained based on SYSMAC CP1L.
Circuit configurations, wiring methods, and programs provided in this manual are given strictly as
examples. When constructing an actual system, check the specifications, performance, and safety of
each component by referring to the respective manuals.
Ladder programs in this manual are provided strictly as examples. When designing the actual circuits,
take adequate safety measures.
Precautions provide general precautions for using the Programmable Controller and related devices.
Section 1 introduces the types of CP1L, as well the part names.
Section 2 explains how to construct a CP1L system, using a shutter control system as an example.
Section 3 explains the how to install CP1L onto a DIN track, how to wire power supply and I/O lines,
and how to test operation.
Section 4 explains the basic functions of CX-Programmer creating the ladder program for the shutter
control system.

3 Safety Precautions
Caution When power is ON or has just been turned OFF, do not touch the power
supply, I/O terminals, or the surrounding areas. Doing so may result in burns.
After turning the power OFF, wait for the unit to cool down sufficiently before
touching it.
Caution Secure the AC power supply line to the terminal block with a 0.5N·m of
torque. Loosening the screw may result in a fire or malfunction.
Caution Before starting online editing, confirm that the extension of cycle time will
have no adverse effects. Otherwise, input signals may not be read.

Used for connection to a computer. Computers can be used for programming
and monitoring.
(3) Analog adjuster
Rotate to adjust the value for auxiliary area A642CH to within the 0 to 255
range. Use to change timer and counter settings without using a programming
tool (software).
(4) External analog settings input connector
Takes an external input between 0 and 10V, and changes the value for
auxiliary area A643CH to a value between 0 and 256. This input is not
isolated.
(5) DIP switches
Used for settings such as write-permission on user memory, automatic
transfers from memory cassettes, and tool bus use.
For details, refer to 2-1 Part Names and Functions of CP Series CP1L CPU
Unit User's Manual (W462).
(6) Battery
Maintains the internal clock and RAM contents while the power supply is OFF.
