It shows that the valve is open now, but after manually closing it, the control panel still indicates that it is open! Does the expert know what the problem is?
If a valve position transmitter or valve position switch is used to send a signal to the PLC for display, it is necessary to check the condition of each component in this circuit. If only the PLC output signal is used as the source for displaying the valve position, it is necessary to check the internal configuration and hardware of the PLC.
What everyone has said is correct; please report the issue as soon as possible. At the same time, inspect the valves of the same model and batch
