  • Page 5: How Communication Works

    ZFV-C controllers have a function for communicating with external devices. Use this function to read the data in ZFV-C controllers from the host and to write the setting data. Communication is achieved via the Command and Response Method based on CompoWay/F, OMRON's proprietary communication protocol.

  • Page 6: Setting The Communication Specifications

    Change the settings of the controller communication specifications for communicating with the external device by CompoWay/F protocol. Use a USB cable or RS-232C cable to connect ZFV-C controllers to external devices. For the USB cable connection, download and install the USB driver beforehand.
