    !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 25 !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 peripheral tool. Otherwise, the devices connected to the output unit may mal- function regardless of the operation mode of the CPU Unit.

    The increase will be a maximum of 190 ms for the CS1D-CPU65H and 520 ms for the CS1D-CPU67H. Set the monitoring time (10 to 40,000 ms, default: 1 s) for the cycle time high enough to allow for this increase. Also, confirm that the system will operate correctly and safely even for the maximum cycle time, including the increase for duplex initialization.

  • Page 32 Application Precautions • When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may result in malfunction or burning. • Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any static build-up.

  • Page 33: Conformance To Ec Directives

    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).

    The CS1D Duplex PLCs conforms to the Common Emission Standards (EN61000-6-4) of the EMC Directives. However, noise generated by relay out- put switching may not satisfy these Standards. In such a case, a noise filter must be connected to the load side or other appropriate countermeasures must be provided external to the PLC.

Duplex initialization is performed only in Duplex Mode.

  • Page 609: 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 610 SW5: OFF (no RS control for RD) SW6: ON (RS control for SD) Note 1. When the NT-AL001 Link Adapter is connected to the RS-232C port on the CPU Unit, 5 V is supplied from pin 6, eliminating the need for a 5-V power supply.
  • Page 611 The 5-V wires can also be twisted with the SG wire to increase noise immunity. 2. When the NT-AL001 Link Adapter is connected to the RS-232C port on the CPU Unit, 5 V is supplied from pin 6, eliminating the need for a 5-V power supply.
  • Page 612 Shell Shield Note 1. Do not use the 5-V power from pin 6 of the RS-232C port for anything but the NT-AL001/CJ1W-CIF11 Link Adapter, or NV3W-M@20L Programmable Terminal. Using this power supply for any other exter- nal device may damage the CPU Unit or the external device 2.
  • Page 613 2. The CJ1W-CIF11 does not provide isolation. The total length of the transmission path must therefore be 50 m or less. If the transmission distance is greater than 50 m, use the NT-AL001, which provides isolation, and do not include the CJ1W-CIF11 in the transmission path. When only the NT-AL001 is used, the total length of the transmission path can be a maximum of 500 m.
  • Page 614 CO-MA-VV-SB 5P 28AWG (7/0.127) (not UL approved) 2. Use a twisted-pair cable for each signal line and SG (signal ground) to connect the CPU Unit to a commu- nications partner. Also, bundle all the SG lines at the Board/Unit and at the other device and connect them together.
