    !WARNING 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 applica- tions.

  • Page 16

    Operating Environment Precautions • The PC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.

  • Page 17

    Application Precautions !Caution The operating environment of the PC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PC System. Be sure that the operating environment is within the specified condi- tions at installation and remains within the specified conditions during the life of the system.

    16-point transmission models. Word Allocation The CPU treats the B7A Interface Unit as an equivalent number of connected I/O Units. The words allocation is identical to that for I/O Units, with inputs and outputs allocated from left to right.

  • Page 26: Bit Allocation

    Words from 000 including the input bits incorporated by the CPU are allocated for input and words from 100 are allocated for output as shown in the following illustration. Refer to the CQM1H or CQM1 Operation Manual for details on I/O word allocation.

  • Page 27

    (see note 3) Note 1. Bit 15 of the input address is allocated as follows, according to the DIP switch input mode setting. 15-point input + 1 error mode setting = transmission error bit 16-point input = input bit 15 Refer to 2-2 Switch Settings.

  • Page 28

    When a transmission error occurs, the input bits are processed according to the transmission error processing setting: HOLD or LOAD OFF. If the input mode is set to 15IN+ERR, the transmission error bit turns ON. The transmission error bit turns OFF when normal transmission is re-estab- lished.
