Guys, I need help with the drawing method of PID diagrams for valves
Thread Content
Gentlemen, what I want to explain is that when the level sensor FT20101 detects a high level, or when the operator presses the button HS20101 from the control panel, the valve XV20101 opens or closes. At the same time, the PLC monitors the position of valve XV20101 and automatically engages interlocking with valve XV20102. Gentlemen, is my way of representing this correct? I would appreciate some guidance
This is a PID, right? There’s no need to draw these things; it’s sufficient to explain them in the instrument documentation
The drawing is fine; just describe it clearly in the sequential logic diagram.
