A PID loop is three nodes and two wires in Melanite. This tutorial builds a temperature controller and tunes it against live process values.
Scaffold tutorial — replace with the real walkthrough + screenshots.
What you’ll build
- A setpoint input bound to an HMI slider
- A PID node with anti-windup
- A Modbus/EtherCAT output to the heater
- A live trend chart of setpoint vs. process value
