  • Page 5 About this Manual: The CPM1 is a compact, high-speed Programmable Controller (PC) designed for control operations in systems requiring from 10 to 50 I/O points per PC. There are two manuals describing the setup and opera- tion of the CPM1: the CPM1 Operation Manual (this manual) and the CQM1/CPM1/CPM1A/SRM1 Pro- gramming Manual.

  • Page 6: Precautions

    PRECAUTIONS This section provides general precautions for using the Programmable Controller (PC) and related devices. The information contained in this section is important for the safe and reliable application of the Programmable Con- troller. You must read this section and understand the information contained before attempting to set up or operate a PC system.

  • Page 7: Intended Audience

    It is extremely important that a PC and all PC Units be used for the specified 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 PC System to the above-mentioned applications.

  • Page 8: Operating Environment Precautions

    Application Precautions Operating Environment Precautions Caution Do not operate the control system in the following places: • Locations subject to direct sunlight. • Locations subject to temperatures or humidity outside the range specified in the specifications. • Locations subject to condensation as the result of severe changes in tempera- ture.
  • Page 9 Application Precautions • Interlock circuits, limit circuits, and similar safety measures in external circuits (i.e., not in the Programmable Controller) must be provided by the customer. • Always use the power supply voltage specified in the operation manuals. An incorrect voltage may result in malfunction or burning. •...
  • Page 10 Application Precautions • Do not touch the Expansion I/O Unit Connecting Cable while the power is being supplied in order to prevent any malfunction due to static electricity. Caution Always clear memory before beginning to program the CPM1. Although memory is cleared before the CPU Unit is shipped (except for bits with specific functions), AR 1314, which turns ON when the internal capacitor cannot back up memory, may have turned ON during shipment.
  • Page 11 Application Precautions If the power remains off for a period exceeding the data backup period, AR 1314 will turn ON to indicate that the capacitor can no longer back up data and the data backed up by the capacitor will be cleared. AR 1314 will remain ON unless it is turned OFF using I/O monitor operations, using memory clear operations, or from the user program.

  • Page 13: Cpm1 Features And Functions

    The CPM1 PCs conform to EC directives (EMC and low-voltage directives), so they can be incorporated in equipment destined for the EC. Contact your OMRON representative for more details. Input Interrupts The CPM1-10CDR-j PCs can handle 2 interrupt inputs; the CPM1-20CDR-j and CPM1-30CDR-j (CPM1-30CDR-j-V1 (Available soon)) PCs can handle 4 interrupt inputs.
  • Page 14 Standard Peripheral Devices The CPM1 uses the same Programming Consoles, SYSMAC Support Software (SSS), and Ladder Support Software (LSS) as the Mini H-type and CQM1 PCs. Programming is Possible Programming operation is possible through the PT screen by using an OMRON Using the PT PT that has a built-in Programming Console function.

  • Page 17 Section 1-1 CPM1 Features and Functions Quick-response Inputs The CPM1-10CDR-j PCs have 2 quick-response input terminals and the CPM1-20CDR-j/30CDR-j PCs have 4 quick-response input terminals. (The same terminals are used for quick-response inputs and interrupt inputs.) Quick-response inputs have an internal buffer, so input signals shorter than one cycle can be detected.
  • Page 18 Section 1-1 CPM1 Features and Functions High-speed Counter CPM1 PCs have a high-speed counter that can be used in incremental mode or up/down mode. The high-speed counter can be combined with input interrupts to perform target value control or zone comparison control that isn’t affected by the PC’s cycle time.
