How to Read PLC Wiring Diagram | PLC Wiring Tutorial for Beginners | PLC Panel Wiring Diagram

✅ Join us here, get awesome perks, and support us, all at once: Read the full blog post at ▶ How to Read PLC Schematics and Diagram In Part 1 of this video series, you’ve learned how to read and understand a wiring diagram of an industrial control panel and in this part, we’re going to continue with the PLC part of that same control panel to learn about some PLC wiring best practices. 👉 To watch Part 1 head to ▶ In this PLC circuit diagram example, we’ll go through different pages of an actual PLC wiring diagram document. First of all, you’ll see how we should power up a PLC CPU and its digital and analog cards. Second of all, you learn about the communication ports of the PLC and its remote IOs such as Profibus ports. Then we check to see which common devices are wired up to our digital input card and digital output card. We’ll also check an analog output card of a Siemens S7 300 PLC and during this investigation, you’ll see how a VFD is connected to a PLC in a wiring diagram. All in all, you will get to know the PLC control panel wiring diagram better than before and become more efficient in your industrial automation career. =========================== ✅ Please SUBSCRIBE to get notified about the new videos: =========================== SECTIONS of this video: 0:00 What you’ll learn in this PLC circuit diagram example 0:37 Rules of Thumb in Wiring Diagrams 1:12 Power connect of a Siemens PLC 2:27 Profibus communication of a Siemens S7 300 PLC (MPI Port/DP Port) 3:34 Siemens Analog Output card wiring diagram (2 and 4 wire connection) 6:34 How PLC commands the VFD to adjust the motor speed 7:24 Siemens Digital Input card wiring diagram 8:37 Siemens Digital Output card wiring diagram 9:12 Where we use a wiring diagram =========================== ▶ If you’ve missed our most recent videos, watch them here: What is a Directional Control Valve?
