Click PLC Analog Input Non-Linear Scaling

The Click PLC has automatic linear scaling for the analog inputs and outputs. What if the analog input or output is not linear? How do you handle this in the PLC? Look at the following tank. We can measure the height, which is linear, but the volume will not because of the shape of the tank.
Click PLC Analog Input Non-Linear ScalingWe will look at an application to determine the volume in this tank. This will be based on the height of the liquid in the tank. We will then scale this non-linear volume of the tank to display the actual volume. Let’s get started.

Productivity 2000 Series PLC Debug Mode

The productivity suite programming software has a debug mode. This will allow you to view and control the rung execution on your ladder logic code. These programming tools allow you to troubleshoot, find, and correct errors in the PLC programming logic.
Productivity 2000 Series PLC Debug ModeWe will be adding a couple of rungs to our exiting start-stop circuit we created last time in our productivity 2000 PLC. Using the debug mode we will explain the scan of the PLC and use these tools to sequence the logic. Let’s get started.

PLC Learning Series – HMI – Interfacing

A human-machine interface (HMI) is present in some form for every PLC. The HMI connects a user to a machine system to exchange information or control data. This interaction with the system can be through hardware or software.
HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, electricians, engineers, and programmers all have different needs. The machine HMI(s) must provide or make the information easy for all the people who use the system.
We will now look at some of the ways that human-machine interfaces (HMI) are used in automated systems today. Let’s get started.

ACC Automation
In this Covid-19 world, we are continuing to adapt. Social distancing, mask-wearing, hygiene, etc are the way we currently live. Video conferencing with Zoom, Teams, and Google Meet are the norm in business today. Information is knowledge, and everyone more than ever wants to be able to see, control and summarize production data on a regular basis. Open intuitive technologies are available to communicate like never before. Industrial plant data is rapidly changing. Factory 4.0 benefits are being seen and everyone wants to take advantage. We are looking forward to the New Year and new possibilities for implementing your control solution.
Raspberry Pi Serial Port Programming - ACC Automation Each year we like to take a few minutes and reflect on the past, current, and future of ACC Automation. You have helped us to build the site that you see today through questions, comments, and suggestions. Thank you.

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 – Program Cyclic Scan

Programmable logic controllers (PLC) use a cyclic scan. The time that it takes to complete one scan is called Scan Time. Typical scan times range from 10 milliseconds to 10 microseconds. This translates from 0.01 to 0.0001 seconds per PLC scan. Understanding how the program scan will help us in programming and troubleshooting the PLC.
The simplest scan cycle of a PLC consists of 4 steps. Read inputs, execute program, diagnostics, and communication, and update outputs.
We will be looking at each of these steps in a little more detail as we discuss the PLC program cyclic scan. Let’s get started.
