Timing Diagram NOT Just Used for a Timer

Logic circuits in a PLC ladder logic program are either on or off. The inputs change, which will affect the outputs. This can be expressed in a timing diagram. The timing diagram or chart will show you how the ladder logic program will respond to the changing states of the inputs and outputs.
Timing Diagram NOT Just Used for a Timer
This visual method is an excellent way of understanding how the PLC ladder logic functions. We will discuss a timing diagram and how it is used for timers, counters, and ladder logic. This will help in understanding or troubleshooting your PLC programs. Let’s get started.

PLC Learning Series – Programming Steps

Developing a programmable logic controller (PLC) program can be broken down into five different steps. These programming steps are as follows:
Five Steps to PLC Program Development
Step 1 – Define the task
Step 2 – Define the Inputs and Outputs
Step 3 – Develop a logical sequence of operation
Step 4 – Develop the PLC program
Step 5 – Test the program
These five steps to PLC program development will help you in understanding, programming, and troubleshooting your automated machine.
PLC Learning Series – Programming StepsWe will be looking at each of these steps in a little more detail as we discuss the PLC programming development. Let’s get started.

PLC Learning Series – Memory Backup

PLC memory is very similar to personal computer memory. There is the operating system and firmware of the processor and connected modules. PLC programs and data that are used by the program are also stored in the memory.
PLC Learning Series – Memory BackupWe will now look at the basic understanding of memory in the PLC. Looking at two examples of PLC specifications. We will see how the program is stored and how long data memory will remain when the PLC is not powered up. Let’s get started.

PLC Learning Series – What are Outputs?

PLC outputs are the next component of our PLC block diagram. The outputs of the PLC will be controlled by the PLC program. Controlling outputs is one way to get the inputs to change. We will be looking at digital and analog outputs that can be wired to the programmable logic controller.
PLC Learning Series - What are Outputs?

PLC troubleshooting outputs will also be discussed. This will be done using a multimeter measuring voltage both at the PLC output and across the discrete output load. We will also measure and control an analog signal output. Let’s get started.

PLC Training Series – Tutorial for Everyone

Invented in 1968 by Dick Morley, the programmable logic controller (PLC) is a simple rugged industrial computer. This free plc training series is designed for everyone to learn about these controllers. PLCs are constantly evolving and continue to be the best option for a variety of industrial automation applications.
PLC Training Series - Tutorial for Everyone
Even though the PLC is changing, core items remain the same. We will be discussing this in more depth for each of the components mentioned in the picture above. Let’s get started learning about PLCs.
