    !"#$%&'()*+ PRECAUTIONS This section provides general precautions for using the Programmable Controller (PLC) and the High-speed Counter Unit. The information contained in this section is important for the safe and reliable application of the High-speed Counter Unit. You must read this section and understand the information contained before attempting to set up or operate a High-speed Counter Unit and PLC system.

  • Page 11: Intended Audience

    It is extremely important that a PLC and all PLC 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 repre- sentative before applying a PLC system to the above mentioned applications.
