AC800M
Technical Specification Analysis Basic Model and Hardware Configuration Model Identification: The AC800M controller is available in a variety of models (such as PM851, PM856, PM860, PM861, PM864, and PM865), and users can choose according to their specific needs. CPU and memory: The power supply unit, CPU processor and memory are integrated on the main board of the controller. Some models support up to 16 tasks. The minimum task cycle can reach 1ms. The resolution of SOE sequential events is less than 1ms to ensure real-time control accuracy.Communication interface: 2 Ethernet interfaces and 2 RS232C interfaces are built in, supporting Modbus, Profibus, Ethernet/IP and other mainstream industrial protocols, compatible with Hart or Profibus physical interfaces, and can be seamlessly connected with sensors, actuators and other control devices. Expansion capability: 12 fieldbus modules are supported for expansion, and up to 8 local I/O stations can be connected through ModuleBus (electrical/optical fiber), or up to 98 remote I/O stations can be connected through ProfibusDP fieldbus expansion to meet the needs of systems of different sizes.Storage and data protection: The memory is used to store and run Firmware, control unit hardware configuration information and application programs, and supports CF flash memory card to save and download application programs for batch deployment. At the same time, some models provide RAM backup batteries to ensure data protection in case of system power loss. Environmental adaptability: industrial design, with anti-vibration, temperature change characteristics, suitable for harsh industrial environment. Some models support redundant settings, such as redundant configuration of CPU, communication interface and I/O module, to improve system reliability.
