The CPM2B is a compact, high-speed board Programmable Controller (PC) designed for control opera- tions. There are two manuals describing the setup and operation of the CPM2B: The CPM2B Operation Manual (this manual) and the CPM1/CPM1A/CPM2A/CPM2C/SRM1(-V2) Programming Manual (W353).

  • Page 7: 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 8: 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 9: Operating Environment Precautions

    Application Precautions • Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. • The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a coun- termeasure for such errors, external safety measures must be provided to en- sure safety in the system.
  • Page 10 Application Precautions • Mounting or dismounting the CPU board or expansion I/O board. • Setting switches or rotary switches. • Connecting or wiring the cables. • Connecting or disconnecting the connectors. Caution Failure to abide by the following precautions could lead to faulty operation of the PC or the system, or could damage the PC.
