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.

EasyPLC Software Suite – Quick Start

The EasyPLC Software Suite is a complete PLC, HMI, and Machine Simulator. This quick start aims to help you quickly learn this software suite. The manual that comes with EasyPLC Software Suite can always be referenced when required.
EasyPLC Quick Start Software Suite
EasyPLC Quick Start Software SuiteWe will be using the simple conveyor in the machine simulator. The EasyPLC PLC will be used to program the ladder logic for this simple conveyor. Compiling and transferring the program to the EasyPLC Virtual CPU, we will demonstrate the conveyor’s control. An HMI will also be programmed to indicate the direction of the conveyor. 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.

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.

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.
