  • Page 23 PRECAUTIONS This section provides general precautions for using the CP-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. Intended Audience .

  • Page 24: 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 25 Safety Precautions • The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. Unexpected operation, however, may still occur for errors in the I/O control section, errors in I/O memory, and errors that cannot be detected by the self-diagnosis function.
  • Page 26 Operating Environment Precautions !Caution After programming (or reprogramming) using the IOWR instruction, confirm that correct operation is possible with the new ladder program and data before starting actual operation. Any irregularities may cause the product to stop operating, resulting in unexpected operation in machinery or equipment. !Caution The CP1L-EL/EM CPU Units automatically back up the user program and parameter data to flash memory when these are written to the CPU Unit.

  • Page 27: Application Precautions

    Application Precautions Application Precautions Observe the following precautions when using the PLC System. !WARNING Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury. • Always connect to 100 Ω or less when installing the Units. Not connecting to a ground of 100 Ω...
  • Page 28 Application Precautions • Do not apply voltages or connect loads to the output terminals in excess of the maximum switching capacity. Excess voltage or loads may result in burning. • Be sure that the terminal blocks, connectors, Option Boards, and other items with locking devices are properly locked into place.
  • Page 29 Application Precautions • Do not connect pin 6 (+5V) on the RS-232C Option Board (CP1W-CIF01) on the CPU Unit to any external device other than the NT-AL001 or CJ1W-CIF11 Conversion Adapter. The external device and the CPU Unit may be damaged. •...
  • Page 30 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).

  • Page 31: Relay Output Noise Reduction Methods

    Conformance to EC Directives Relay Output Noise Reduction Methods The CP1L-EL/EM PLCs conforms to the Common Emission Standards (EN61131-2) 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.
  • Page 32 Conformance to EC Directives Circuit Current Characteristic Required element The varistor method prevents the impo- Varistor method sition of high voltage between the con- tacts by using the constant voltage characteristic of the varistor. There is time lag between the moment the cir- cuit is opened and the moment the load Power is reset.

    Section 8-1 Interrupt Functions Interrupt Functions 8-1-1 Overview of CP1L-EL/EM Interrupt Functions The CP1L-EL/EM CPU Unit’s processing is normally cyclical (overseeing pro- → → → cessing program execution I/O refreshing peripheral servicing), with cyclic tasks executed in the program execution stage of the cycle. The inter- rupt functions can be used to temporarily interrupt this cyclic processing and execute a particular program when a predefined condition occurs.

  • Page 410 Section 8-1 Interrupt Functions Interrupt Task Priority The input interrupts (direct mode and counter mode), high-speed counter interrupts, scheduled interrupts, and external interrupts all have the same pri- ority. If interrupt task A (an input interrupt, for example) is being executed when interrupt task B (a scheduled interrupt, for example) is called, task A processing will not be interrupted.
  • Page 411 Section 8-1 Interrupt Functions a. The following example shows duplicate processing by an interrupt task, which interrupts processing of a +B instruction between the first and third operands and overwrites the same memory address. Cyclic task Interrupt task #0010 #0001 Flow of Processing Read D0 value (1234).

    Appendix E Memory Map PLC Memory Addresses PLC memory addresses are set in Index Registers (IR00 to IR15) to indirectly address I/O memory. Normally, use the MOVE TO REGISTER (MOVR(560)) and MOVE TIMER/COUNTER PV TO REGISTER (MOVRW(561)) instructions to set PLC memory addresses into the Index Registers. Some instructions, such as DATA SEARCH (SRCH(181)), FIND MAXIMUM (MAX(182)), and FIND MINIMUM (MIN(183)), output the results of processing to an Index Register to indicate an PLC memory address.
