  • Page 8: How Communication Works

    ZS Series controllers have communication functions with external devices. Use this function to read the data in ZS Series controllers from the host and to write the setting data. Communication is achieved via the Command and Response Method based on the CompoWay/F, which is Omron's proprietary communication protocol.

  • Page 58: About Obtaining Flow Data

    To handle the measurement data with external devices, it is necessary to obtain a large volume of data. The ZS series provides a system to handle measurement data as a bunch of any number of data items and to obtain data in units of bunches.

  • Page 59: Setting Procedures For Data Obtaining Conditions

    That is to say, the LDC itself as a single unit cannot obtain measurement data at every 112 microseconds via communications. To obtain the measurement data at every 112 microseconds, use a composition of ZS-LDC and ZS-MDC to obtain the measurement data from ZS-LDC via ZS-MDC.
