In the world of panel drawings, understanding and reading a wiring diagram is a valuable skill. Not only does it help you build and troubleshoot panels, but it also allows you to find the root cause of any problem. In this article, we will guide you through the process of effectively reading a PLC (Programmable Logic Controller) wiring diagram. So, let’s dive in!

To start, let’s identify the push buttons on the control panel we are analyzing. In this case, we have the “Mute Buzzer” push button, the “ESD Reset” push button, and the “Emergency Stop” push button. Remember these buttons as we will be referring to them later.
Understanding the Wiring Diagram
The wiring diagram we are using is created using AutoCAD. Each page of this diagram represents the wiring for different sections of the control panel. For example, if we look at the Emergency Stop push button, we can see that there are four wires connected to it.
Following the Wire Connections
To understand the wiring connections, we follow the tags and page references on the diagram. Each wire has a tag number, which helps us trace its path. For instance, we can see that one wire comes from page 200, section 1, and ends on page 311, section 1. By navigating between the pages, we can visually identify the specific wire on the diagram.
Connecting to the PLC
Some of the wires are connected to the PLC inputs and outputs. By referring to the diagram, we can find the tags for these connections. For example, we can see that one wire with the tag 2 is connected to the PLC digital input labeled as 300U2.1. By locating the corresponding wire on the diagram, we can understand how the push button is connected to the PLC.
Replicate the Process for Other Switches
Repeat the same process for the other switches on the control panel. By following the tags and page references, you can easily trace the wire connections and understand how each switch is wired to the PLC.
Conclusion
Reading a PLC wiring diagram may seem daunting at first, but by following these steps, you can easily navigate the diagram and understand the connections. Remember, a wiring diagram is a powerful tool for building, troubleshooting, and maintaining control panels.
