Das Szenario
Designing a PLC-based control system for maintaining water level in a tank using float switches to sense high and low levels and a pump to fill the tank.
Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
01
Using pull-down resistors to ensure reliable PLC input states when switches are open
02
Using a relay output module to drive the pump motor for isolation and power handling
When automating a tank filling process with PLC control, suitable for water treatment, manufacturing, or agricultural water storage.
