Composition structure of on-site controller
The on-site controller uses computer technology to monitor and control the status and parameters of the controlled objects on site, such as monitoring and alarming the status and parameters of equipment and systems, open-loop and closed-loop control, etc. At the same time, it is also connected to the higher-level computer to receive instructions and management information from the higher-level computer, and transmits on-site ticket supply data upwards. It generally consists of a power module, a computer (CPU) module, a communication module, and an input/output module. In addition, when used alone, an on-site human-machine interface module should also be added.
