!WARNING 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 39 !Caution Confirm safety before transferring data files stored in the file memory (Mem- ory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a Programming Device. Otherwise, the devices connected to the output unit may malfunction regardless of the operation mode of the CPU Unit.
Page 40: Operating Environment Precautions
If a battery error occurs, the con- tents of the areas that are set to be held may not be accurate even though a memory error will not occur to stop operation. If necessary for the safety of the system, take appropriate measures in the ladder program whenever the Bat- tery Error Flag (A40204) turns ON, such as resetting the data in these areas.
Page 41: Application Precautions
• Always connect to a ground of 100 Ω or less when installing the Units. Not connecting to a ground of 100 Ω or less may result in electric shock. • A ground of 100 Ω or less must be installed when shorting the GR and LG terminals on the Power Supply Unit.
Page 42 BUSY indicator to go out before removing the Memory Card. • If the I/O Hold Bit is turned ON, the outputs from the PLC will not be turned OFF and will maintain their previous status when the PLC is switched from RUN or MONITOR mode to PROGRAM mode.
Page 43 • Install Units as far as possible away from devices that generate strong, high-frequency noise. • Do not apply voltages to the Input Units in excess of the rated input volt- age. Excess voltages may result in burning. • Do not apply voltages or connect loads to the Output Units in excess of the maximum switching capacity.
Page 44 Using commercially available cables may damage the external devices or CPU Unit. • Do not connect pin 6 (+5 V power supply line) of the RS-232C port on the CPU Unit to any external device except the CJ1W-CIF11 RS-422A Adapter, NT-AL001 RS-232C/RS-422A Adapter, or NV3W-M@20L Pro- grammable Terminal.

Page 52 I/O is allocated to the connected Units each time the power is turned ON (same as CQM1H PLCs). 2. User-set I/O Allocation If desired, the user can set I/O tables in the same way as for the CS-series PLCs. The default setting is for automatic I/O allocation at startup, but the user can set the PLC to automatically use I/O tables to enable checking for Unit con- nection errors or to allocate unused words.
Page 53 I/O names are handled as symbols which can be defined as global symbols, Supported which apply to all of the programs in all tasks, or as local symbols, which apply to just the local task. When the symbols are defined, you can choose to have the local symbols allocated to addresses automatically.
Page 54 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.

Page 426 Input Bits A bit in the I/O Area is called an input bit when it is allocated to an Input Unit. Input bits reflect the ON/OFF status of devices such as push-button switches, limit switches, and photoelectric switches. There are three ways for the status of input points to be refreshed in the PLC: normal I/O refreshing, immediate refreshing, and IORF(097) refreshing.
Page 427 When the immediate refreshing variation of an instruction is specified by inputting an exclamation point just before the instruction, and the instruction’s operand is an input bit or word, the word containing the bit or the word itself will be refreshed just before the instruction is executed. This immediate refreshing is performed in addition to the normal I/O refreshing performed once each cycle.
Page 428 Limitations on Input bits There is no limit on the number of times that input bits can be used as nor- mally open and normally closed conditions in the program and the addresses can be programmed in any order.
Page 429 0.5 ms to 32 ms. Note If the time is set to 0 ms, there will still be an ON delay time of 20 µs max. and an OFF delay time of 300 µs due to delays caused by internal elements.
Page 430 The following IORF(097) instruction refreshes the status of all I/O points in I/O Area words CIO 0000 to CIO 0003. The status of input points is read from the Input Units and the status of output bits is written to the Output Units.

Page 634 Contact Protection Circuit Arc killers are used with the Contact Output Unit in order to prolong the life of each Relay mounted to the Con- tact Output Unit, prevent noise, and reduce the generation of carbide and nitrate deposits. Arc killers can, how- ever, reduce relay life if not use correctly.
Page 635 Note Do not connect a capacitor as an arc killer in parallel with an inductive load as shown in the following dia- gram. This arc killer is very effective for preventing spark discharge at the moment when the circuit is opened.
Page 636 This section describes the load short-circuit protection of the CJ1W-OD202 Output Units. As shown below, normally when the output bit turns ON (OUT), the transistor will turn ON and then output cur- rent (Iout) will flow. If the output (Iout) is overloaded or short-circuited exceeding the detection current (Ilim), the output current (Iout) will be limited as shown in Figure 2 below.
Page 637 The CJ1W-OD202 turns ON an alarm output bit that corresponds to the external load output number. There is an alarm output bit for every common. When an alarm output bit turns ON, use a self-holding bit for the alarm in the user program and turn OFF the corresponding output.

Page 703: Connecting To The Rs-232C Port On The Cpu Unit
CPU Unit Connection Examples The wiring diagrams for connecting to the RS-232C port are provided in this appendix. In actual wiring, we rec- ommend the use of shielded twisted-pair cables and other methods to improve noise resistance. Refer to Rec- ommended Wiring Methods later in this appendix for recommended wiring methods.
Page 704 The recommended cables should be wired as shown below. Each signal wire should be twisted with the SG (signal ground) wire and placed in a shielded cable to prevent the effects of noise in noise- prone environments. The 5-V wires can also be twisted with the SG wire to increase noise immunity.
Page 705 6, eliminating the need for a 5-V power supply. 3. Do not use the 5-V power from pin 6 of the RS-232C port for anything other than an NT-AL001, CJ1W- CIF11 Link Adapter, or NV3W-M@20L Programmable Terminal. Using this power supply for any other external device may damage the CPU Unit or the external device.
Page 706 Note The CJ1W-CIF11 is not insulated, so the total transmission distance for the whole transmission path is 50 m max. If the total transmission distance is greater than 50 m, use the insulated NT-AL001, and do not use the CJ1W-CIF11. If only the NT-AL001 is used, the total transmission distance for the whole transmission path is 500 m max.
