Architecture of DCS systems

The structure of DELTA V consists of an operation station and controllers as nodes, connected to a switch; steps for configuring switch redundancy: 1. Assign channels, 2. Configure control strategies, 3. Assign to controllers, 4. Install

Your question is too general, isn’t it? DCS architecture: Signals are transmitted from the field to the DCS; the DCS sends them to the main control card for processing and analysis, and then the results are sent to a computer for display. Control is implemented by the computer, which generates control signals based on the control scheme and sends them to the DCS main control card for further analysis, after which the corresponding control signals are transmitted via a switch network to the instruments in the field. Configuration steps: First, it is necessary to determine how many field instruments need to be controlled by the DCS; accordingly, the I/O configuration is prepared. After that, a control strategy suitable for the requirements is developed, such as batch control or ratio control ； Then download the configuration and carry out debugging until the configuration program operates properly and accurately!
