Wire and test a start-stop motor circuit on the P1-M622-16DR Mini PLC — pushbuttons, ferrules, and an LED motor output, tested in Stop and Run mode.
⚡ QUICK ANSWER
Wiring a start-stop circuit to the P1-M622-16DR Mini PLC means landing your start and stop pushbuttons on discrete inputs and the motor output on a discrete output — here an LED stands in for the motor so you can test safely. Start by reading the terminal block layout so you know which terminals are inputs, outputs, and commons, and use ferrules on the stranded wire ends for clean, reliable connections. Wire the start button to one input, the stop button to another, and the LED to an output. Then verify everything in PLC Stop mode (checking the physical connections and input status) before switching to Run mode to confirm the ladder logic latches and unlatches the motor output. The full wiring and step-by-step test are in the written guide below.

📚 WHAT YOU'LL LEARN
✅ Read the P1-M622-16DR terminal block layout — inputs, outputs, and commons
✅ Why ferrules make for cleaner, more reliable wire connections
✅ Wire start and stop pushbuttons to the Mini PLC's discrete inputs
✅ Wire an LED motor indicator to a discrete output
✅ Test the circuit in both Stop and Run mode, and troubleshoot common issues
❓ FREQUENTLY ASKED
Q: How do you wire a start-stop circuit to the P1-M622-16DR?
A: Land the start and stop pushbuttons on discrete inputs and the motor output (here an LED) on a discrete output, using the terminal block layout to identify inputs, outputs, and commons. The full diagram is in the guide.
Q: Why use ferrules on the wires?
A: Ferrules crimp onto stranded wire ends so they seat cleanly and reliably in the terminal block, preventing stray strands and loose connections.
Q: Why test in Stop mode before Run mode?
A: Stop mode lets you verify the physical wiring and confirm each input registers before the program can drive outputs — a safe way to catch wiring mistakes early.
