From code to a controlled process.
Adjust the level setpoint, inflow or PID. Use MAN for gate control, or try the 40-second challenge.

CASCADE: level PID sets an outflow setpoint; inner flow PI limits gate opening to the waterline.
Inflow · IN36%
Water level · PV58.0%
Setpoint · SP62.0%
Gate open · OUT42.0%
A low water level can cause water shortages and equipment to run dry. Overflow can cause flooding. Both conditions trigger visible alarms.

Control modesHow the demo works
CascadeLevel PID provides a flow setpoint to an inner PI controller. In this demo, gate opening is limited to the current water level. At high inflow and low level, the setpoint may be unreachable.
Without cascadeThe level PID commands the gate directly using a nominal flow-to-gate conversion, with full 0–100% travel.
PID / Structured TextThe PID adjusts the gate to track setpoint. The Structured Text display illustrates the controller calculations as you tune Kp, Ki and Kd.
Manual / 40 s challengeYou control the gate. Two inflow changes and a burst of heavy rain make the 40-second challenge more demanding.

How sorting worksSignals / diagnostics
Colour sensor & routingThe colour sensor assigns each package a destination: A, B or straight ahead. The selected route is retained as the package moves along the conveyor.
Pneumatics & countingTwo pneumatic pushers divert packages to A and B. Unsorted packages continue straight. Each exit has a counter.
Jam · Photoeye timeoutA PLC can monitor the expected travel time between sensors. A package that takes too long to clear a photoeye or reach the next sensor may be blocked.
Jam · Motor monitoringA blockage may increase motor current or torque, or cause a speed deviation. A drive can detect these conditions. Create jam simulates either fault; no physical measurements are made.
