The FM265A embodies more thorough decentralisation, so that even the failure of any one front-end does not affect the normal operation of other front-ends. Flexible on-site installation with sensors and actuators in close proximity saves wiring and the number of IO points on the PLC itself. High-speed data transmission is provided for reliable communication between the controller CPU and the I/O system. The field level is thoroughly decentralised, while safety barriers, isolators, I/O modules, field cables and terminals are significantly reduced, so the Distributed Remote IO Module greatly improves its maintenance performance.

The I/O points of FM265A system are about 120, and the DI and DO points are basically equal. In order to solve the above problems, we adopt the 214 CPU module of Siemens S7-200PLC, and the rest of the I/O modules and the AI module for water content detection adopt the UN200 series of EVERWAY, and the dosage metering is realised by PLY600, which is a dosage control instrument developed by Shandong Boshuo itself. In the UN200 module, 8DI/8DO digital modules are also used as keyboard scanning modules to collect signals for manual operation.
