Page 24 PRECAUTIONS This section provides general precautions for using the CJ-series Programmable Controllers (PLCs) and related devices. The information contained in this section is important for the safe and reliable application of Programmable Controllers. You must read this section and understand the information contained before attempting to set up or operate a PLC system.
Page 25: Intended Audience
It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
Page 26 Safety Precautions !WARNING Do not touch any of the terminals or terminal blocks while the power is being supplied. Doing so may result in electric shock. !WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
Page 27: Operating Environment Precautions
Operating Environment Precautions !Caution A CJ1-H or CJ1M CPU Unit automatically back up the user program and parameter data to flash memory when these are written to the CPU Unit. I/O memory (including the DM, EM, and HR Areas), however, is not written to flash memory.
Page 28: Application Precautions
Application Precautions Application Precautions Observe the following precautions when using the PLC System. • You must use the CX-Programmer (programming software that runs on Windows) if you need to program more than one task. A Programming Console can be used to program only one cyclic task plus interrupt tasks. A Programming Console can, however, be used to edit multitask pro- grams originally created with the CX-Programmer.
Page 29 Application Precautions • Always turn ON power to the PLC before turning ON power to the control system. If the PLC power supply is turned ON after the control power sup- ply, temporary errors may result in control system signals because the output terminals on DC Output Units and other Units will momentarily turn ON when power is turned ON to the PLC.
Page 30 Application Precautions • Be sure that all the terminal screws, and cable connector screws are tight- ened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction. • Leave the label attached to the Unit when wiring. Removing the label may result in malfunction if foreign matter enters the Unit.
Page 31: Conformance To Ec Directives
Concepts EMC Directives OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the overall machine. The actual products have been checked for conformity to EMC standards (see the following note).

Overview Section 1-1 Overview The CJ-series PLCs are very small-sized Programmable Controllers that fea- ture high speed and advanced functions with the same architecture as the CS-series PLCs. • Only 90 x 65 mm (H x D) for mounting in small spaces in machines and on the same DIN Track as components, contributing to machine downsiz- ing, increased functionality, and modularization.
Page 36: Cj-Series Features
CJ-series Features Section 1-2 The CJ-series PLCs support the same task-based programming structure, instructions, high-speed instruction execution, I/O memory, functionality, and message communications as the CS-series PLCs. The main differences of the CJ-series in comparison to the CS-series PLCs are as follows (refer to page 68 for details): •...

Page 38 CJ-series Features Section 1-2 Using Symbols Arbitrary symbols (names up to 32 characters) that are independent of I/O ter- minal allocations can be used in programming. Standard programs created with symbols are more general and easier to reuse as tasks in different pro- grams.
Page 39 Symbols that read and write data to the CPU Unit can be included in the com- munications frames, so data can be exchanged with the CPU Unit very easily. OMRON components (such as Temperature Controllers, ID System Devices, Bar Code Readers, and Modems) can be connected to a Serial Communica- tions Unit with the standard system protocol.
Page 40 CJ-series Features Section 1-2 Multilevel Network Configurations Different network levels can be connected as shown in the following diagram. The multilevel configuration provides more flexibility in networking from the manufacturing site to production management.
