  • Page 16: 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 17: Operating Environment Precautions

    Operating Environment Precautions !WARNING Provide safety measures in external circuits (i.e., not in the Programmable Controller), including the following items, to ensure safety in the system if an abnormality occurs due to malfunction of the PLC or another external factor affecting the PLC operation.

  • Page 18: Application Precautions

    Application Precautions Application Precautions Observe the following precautions when using a CompoNet Network. • When more than one CompoNet system use Flat Cables, always sepa- rate the Flat Cables from each other by at least 5 mm regardless of whether Flat Cable I or II cables are used. Do not bundle the Flat Cables. This is to prevent unstable operation of the system due to interference.
  • Page 19 Application Precautions • Take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction. • Do not apply voltages to the Input Units in excess of the rated input volt- age.

    CompoNet Networks Section 1-1 CompoNet Networks 1-1-1 Overview CompoNet Networks feature easy operation and installation in a component- level network connecting PLCs and on-site I/O. The PLC and CompoNet Slave Units cyclically exchange I/O information through a CompoNet Master Unit, refreshing I/O in sync with the PLC scan. Message communications can also be used from host computers or the CPU Unit of the PLC to read and write CompoNet Slave Unit data.
  • Page 25 Section 1-1 CompoNet Networks Communications Cables CompoNet Networks use Round Cable I, Round Cable II, Flat Cable I (DCA4- 4F10 Standard Flat Cable), and Flat Cable II (DCA5-4F10 Sheathed Flat Cable) for Communications Cables. Master Unit The Master Unit manages the CompoNet Network and transfers I/O data between the PLC and the Slave Units.
