How to represent the signals from the distribution cabinet to the DCS in a PID diagram?
Thread Content
The signals from the variable frequency motor come from the power distribution cabinet to the DCS; I need to display these signals on the PID chart. How should I do that?
Like the signals from other devices, it’s sufficient to show the signals that need to be drawn from the motor; in the PID display they appear to come from the motor, but in reality they originate from the power distribution cabinet
For example, change the DCS instrument tag to SIC-001, and then direct the signal output to the motor.
The signal from the DCS can only be sent to the frequency converter or the control terminal of the secondary circuit; it cannot be sent directly to the motor.
