Our new project uses Turbomachinery’s turbines and compressors; the legends on them are not very clear. I’d like to ask an expert
Thread Content
Among them, there is one legend: in the case of turbines, its English translation is \"mounted on main control system (DCS)\\", while for compressors, the same legend is expressed as \"DCS on main control panel\". How should one understand these two translations? What’s the difference between them? Thank you
It is these two systems that need to communicate with the DCS
It would be best to upload a screenshot of the legend. Control panel: I remember there was a Siemens PLC with anti-surge functionality at the man station, along with a touchscreen control panel
Posting a picture might help to understand or explain it better. One is DCS, and the other is a control panel.
Being mounted on the main control system (DCS) may refer to the signal exchange between the local control system of the compressor and the DCS; the hardware that generates such signals is installed within the DCS system, such as the isolation valves used by the DCS to start and stop the compressor, or certain signals from the compressor that are sent to the DCS； As for the DCS on the main control panel, the name is a bit strange. It’s just a guess; we need to see the P&ID to be sure.
