I’m working on this process, and I’d like to ask the experts in instrumentation: what are the steps required to develop a DCS from scratch to its final form?

Civil engineering, base fabrication, cabinet installation, wiring, power-up, communication testing, single-point debugging, circuit testing, etc

From design and development, installation and commissioning to final application.

1. Design: The PID drawings are prepared, followed by preliminary review and approval. Modifications suggested by HOZAP analysis as well as those proposed during the drawing review are considered, leading to the final version； 2. Propose the process parameters for instrument design, and submit them for automatic control design ； 3. Determination of various parameters for the instruments, finalization of the I/O list ； 4. The DCS design quotation document is prepared, and system bidding is carried out in accordance with the I/O list and configuration requirements ； 5. The DCS system supplier is selected through bidding; the DCS manufacturer works together with the design team to verify the I/O list and the control scheme. The DCS interface screens are reviewed together with the client and the design party. Once the cabinet design plan is finalized, installation and configuration begin ； 6.FAT ； 7. The on-site cabinet room is ready (with electricity supply in place, air conditioning in place, and interior decoration completed and handed over); shipment, on-site inspection, and installation of the cabinets along with various panels and screens ； 8. The manufacturer conducts an on-site inspection to verify that everything is in order, after which the system is powered on for testing ； 9. Finalize the modifications to the configuration interface, make adjustments to any additional elements that may be needed, modify certain aspects of the design, and finally confirm the control permissions and monitoring permissions ； 10. On-site equipment integration testing, control circuit integration testing, various alarm interlock tests, as well as testing of the control system’s forward and reverse operations and its functions ； 11. Final system acceptance and delivery ； 12. Official commissioning of the system. The steps mentioned above may be carried out simultaneously in some cases, but they are all necessary tasks. The order in which these tasks are performed may vary, yet the basic requirements remain the same

Simple – it’s just creating something from nothing. The project is entrusted to a qualified construction company, and the owner only needs to take one step, namely carrying out a turnkey procurement for the project.

This is too complicated for the original poster

DCS manufacturers, as fellow descendants of the Yan and Huang tribes, let’s give each other a chance. 15169070869:lol
