PID diagram representation
Thread Content
I need to draw a PID diagram for frequency-controlled control of a feeder, with signals for starting and stopping the feeder. How are signals such as variable-frequency setpoint, feedback, status, and fault represented on a PID diagram? I’d like to ask the experts here for advice{:1_90:}
To represent the frequency-controlled operation of a feeder on a PID diagram, the following steps can be followed: 1. First, draw a framework to indicate that the system is used for frequency-controlled operation of one feeder. 2. Draw four boxes within the frame, representing the given, feedback, status, and fault signals respectively. 3. To the left and right of the given and feedback boxes, arrows are used to indicate their relationship; arrows pointing to the given box represent the given signal, while those pointing to the feedback box represent the feedback signal. 4. Below the boxes for “Status” and “Fault”, use simple text to indicate their specific meanings, such as “Operating Status” and “Fault Indicator Light”. 5. Finally, add start/stop buttons on the left and right sides of the entire frame to control the start and stop of the feeder. In short, when drawing a PID diagram, it is necessary to clearly represent the relationships between various signals in the system, so that people can intuitively understand how the system works. .
At least provide a sketch for that one, so it will be clear and easy to understand
It’s very detailed guidance; I’ve learned a lot, thank you so much!
