IV. Working Principle


After DC24V power-on and self-check of display, keypad and communication circuits, the panel loads local HMI project and establishes communication handshake with AC800M controller via preset IP and protocol. It cyclically reads process data for screen refresh, uploads field operation commands to the controller through key triggering, and automatically caches alarm and operation events to local non-volatile memory. After fault elimination, alarm reset and screen switching can restore normal local monitoring function.


V. Application Scenarios


  1. Local operation station maintenance, spare replacement and process parameter calibration for thermal & hydropower plant DCS and excitation control systems.
  2. HMI technical upgrading for petrochemical and gas compressor stations to improve on-site operation reliability under harsh dusty & humid working conditions.
  3. Intelligent renovation of old local monitoring equipment for steel and waste heat power plants to realize data storage and permission safety management.
  4. Preventive spare reserve and on-site interlock calibration for continuous production lines in pulp and chemical industries.
  5. Supporting local operation equipment deployment for overseas new industrial automation projects to simplify field commissioning and daily maintenance work.
