How to view the control logic and interlock logic of instruments in a PID?
Thread Content
The new installation is currently in the design review phase; the instrument legends can be found in the PID. But I would like to ask how to determine the control logic and interlock logic for the instruments Are there any relevant PPT presentations or books that can be used for learning?
In the PID, only the interlock numbers, the instruments, valves, and other components involved are visible; the logic is represented in a separate interlock logic diagram.
The control logic can be understood by looking at PID; for more complex controls, there are also control schemes. Interlock logic is represented by specialized logic diagrams or cause-and-effect diagrams, and essentially all of these are composed of AND, OR, and NOT gates.
I want to learn how to approach things using this kind of logic through learning materials
This is a control circuit diagram; it lacks logic. Complex control loops become simpler when considered separately.
The design institute will only provide the interlock logic table, right? The logic diagram is created by your DCS supplier based on the interlock logic table.
