How is the emergency stop system represented in PID?
Thread Content
Dear netizens, how is the emergency stop system represented in PID? Can anyone provide a diagram for reference?
The drawings I’ve come across usually have SIS marked on them, either through designated tag numbers or by using special colors for the lines; in most cases, they are easy to identify.
Refer to “HG/T 20505-2014 Functional Indicators and Graphic Symbols for Process Measurement and Control Instruments””
Bro, do you have the blueprints? Could I take a look? Thanks!
Excuse me, what interlock is associated with that emergency stop?
:L:L:L: It would be fine if it followed the standard P&ID drawing conventions
Could you provide a P&ID diagram for reference?
Examples are provided in “HG/T 20505-2014 Functional Indicators and Graphic Symbols for Process Measurement and Control Instruments”

Is it the part inside the circle in the picture, bro?
The emergency stop PID diagram cannot be indicated; it is specified on the interlocks
