Industrial Automation Using PLC (Programmable Logic Controller) and STONE Touch screen LCD / HMI (Human Machine Interface)

We are going to implement a box sorting machine with PLC and conveyor belt including LCD/Touch screen for controlling and monitoring.

It has the following main parts:

1.      PLC (Programmable Logic Controller)

2.      HMI (Human Machine Interface)/ LCD Stone HMI

3.      Conveyor Belt

4.      Motors

5.      Sensors (Height and Weight sensor)

Prototype Arrangement can be seen as below.

Let’s discuss some details and causes of this application of HMI (Human Machine Interface)

Control system has become backbone of every industry overtime. Before, humans were the major source for controlling systems. In recent past controlling was done by electrical relays. In this modern and advance technology’s era electricity is used for controlling and monitoring purposes.Especially in industry it plays a vital rule in controlling the heavy machinery and hence the chances of hazards have been reduced on a huge scale and human security is ensured. Simply we can say that control system has made our lives much easy.  

There are many controllers available in market now a days such as PIC, AVR, 8051 and Arduino microcontrollers they all have their importance in many areas of control engineering. PLC (Programmable Logic Controller) has brought revolution and replaced hard wired electrical wiring and relays with simple program and controller.

PLC got favor in industry due to following benefits:

Ø  Cost effective for complex control systems

Ø  Constructed in modular form so that modules can be separated easily for repair

Ø  Computational abilities allow more sophisticated control.

Ø  Trouble shooting aids make programming easier and reduce downtime

Ø  Easy HMI LCD configuration (SONE HMI Touch screen LCD)

Ø  Reliable components make these likely to operate for years before failure

Ø  They are more immune to vibration, humidity and perfect to be operated in Industrial environment [2]

You can say PLC as minicomputer as it has CPU (Central Processing Unit) and memory.Languages used to program PLC include Ladder diagram, Sequential Function Charts, Function Block Diagram, Structured Text, and Instruction List. PLC is flexible a device, program in the PLC can easily be changed to include future enhancements in the system.

How to assemble LCD LCD screen correctly?

 Many devices in our lives will use LCD LCD screen, today to specifically analyze how to properly assemble LCD LCD screen, I hope to help you. LCD the tools assembled by the LCD screen are mainly hammers and wrenches, which are used to screw the frame foot. The order of assembly operation is to put all the tools and raw materials on the workbench in an orderly manner first. Second, the shell according to the process card instructions correctly placed on the worktable, if there is assembly tooling, as required on the tooling, pay attention to the shell direction to be correct. Next remove the protective film of the LCD screen, wipe the electrode with dust-free paper, confirm the direction, according to the process card instructions, correctly put into the shell. remove the circuit board, if you want to add a backlight, the backlight is first fixed on the PCB board. Align the circuit board to the frame position according to the process card. Load the housing to press the zebr

What is HMI and Why Use STONE HMI Display?

HMI is changing the way several industries are run now. It is a technology that automates several fields and improves productivity and efficiency on many levels. The merging of humans and machines through HMI is simply the next norm in industrial automation. Interested in finding out more about HMI? Read on to get a general overview of this technology. Also, we’ll introduce STONE HMI displays and why they’re among the leaders in HMI technology worldwide. Defining what HMI is HMI stands for Human Machine Interface. It consists of a dashboard allowing a person to manipulate and interact with a system, device, or machine. HMI is often regarded as the merger of humans and machines for better automation efficiency. HMI is also known as: Operator Interface Terminal (OIT) Man-Machine Interface (MMI) Local Operator Interface (LOI) Operator Terminal (OT) The HMI presents visual information regarding a system to the user. The person, in turn, can operate and control the

Use STONE HMI Make a Smart Home Control System

Project introduction The following tutorial shows you how to use the STONE  STVC050WT-01  touch display module to make a simple home appliance control system. STONE  STVC050WT - 01  the support touch display module is 5 inches, 480 * 272 resolution on the module has been integrated display and touch screen driver needed chips, developers need only on the STONE, the official VGUS design software related UI interface design and generate a programming file downloaded to the STONE display module, and then through a serial port (RS232 / RS485 / TTL) correspond with it, you can perform complex UI design aspects. The process is as follows: The following image shows some parameters of the STONE STVC050WT-01 display module: This display module is just one of many in this line of products. There are many other display modules available in different configurations.  www.stoneitech.com STONE display module development three steps: Designed th
