When you look at an industrial control panel wiring diagram despite how many pages they include, they most probably consist of two sections. One is the “Power or main circuit” and the other is the “Control circuit.”

In this video:
1. We'll check and understand the logic behind a Forward and Reverse motor control wiring diagram by means of a practical industrial example.

2. We're going to convert that old Clockwise/Counterclockwise motor control wiring to a PLC wiring diagram.

3. You'll learn how to draw a basic wiring diagram with EPLAN Electric P8. So this part would be very helpful in case you're not familiar with Electrical CAD software.

4. You'll understand the basics of how to convert a wiring diagram to a Ladder diagram in the TIA Portal V16.

The mechanism that we're going to take as an example, is a three-phase electric motor that is installed on a conveyor system that moves the pallets toward a check weigher machine.

In this process, sometimes the operator must stop the conveyor, and sometimes turns on the conveyor in the reverse direction to move the pallets backward.

It is possible to implement this mechanism without a PLC but as you may know, these days, even for small-size processes we use PLC systems to control ALL of the mechanisms in the process, reduce the cabling works, and have more control over the process.

In a future video, you will learn how to wire the actual electrical devices of this process, download this software to the PLC, and simulate the process.

I really hope you'll learn something new from this video. If so happens, please LIKE and share this video with your friends, colleagues, or your students.
