The software system of DCS can usually provide users with a wealth of functional software modules and functional software packages. Control engineers use the configuration software provided by DCS to properly “assemble and connect” (that is, configure) various functional software to generate various application software that meet the requirements of the control system.

software system

The software of the on-site control unit mainly consists of software modules such as data inspection, control algorithm, control output, and network communication centered on the real-time database.

The real-time database plays a central role in data sharing, where each execution code exchanges data with it to store on-site collected data, control output

intermediate results of certain calculations, and control algorithm structure information. The data inspection module is used to collect on-site data and fault signals, and to achieve necessary auxiliary functions such as digital filtering, unit transformation, compensation calculation, etc. The control function of DCS is generated through configuration. Different systems require different control algorithm modules, which usually involve the following modules: arithmetic operation module

logic operation module, PID control module, variant PID module, manual automatic switching module, nonlinear processing module, actuator control module, and so on. The control output module mainly realizes the output of control signals for fault handling.software systemThe operation station in DCS is used to complete tasks such as system development
