PLC Programming for Vision Checking System with Linear Servo Motors

PLC programs provide precise control over machinery and industrial processes. They dictate how equipment operates, ensuring tasks are performed accurately and consistently according to predefined parameters. In this project, I create the PLC program for a Mitsubishi PLC and design the HMI screen template using Mitsubishi HMI software for a vision checking system integrated with linear servo motorsTop of Form. In vision checking system with linear servo motors inspects PCBA and wiring using a vision camera moved by a servo gantry system. Safety measures are implemented. The program includes auto, manual, and homing sequences, along with mode selection, error handling, counter, shift, and tower lamp functions. HMI screens are designed to teach machine operation. In auto mode, servos move to positions set in the HMI recipe screen. Manual mode allows servo jogging and movement between positions via the HMI servo screen. Pressing the homing button moves servos to user-set home positions. Safety measures, including light curtains, door switches, and fixture sensors, halt the machine and sound a buzzer in case of errors. Counter and shift programming displays running shift and component counts. Programs are tailored to input/output device operations. Key Words: PLC Programming, HMI Screen designing.

Design of Intelligent Greenhouse Control System based on MCGS and PLC

In modern agriculture, intelligent greenhouse systems have become a critical component for optimizing crop growth and maximizing yield. By integrating information technology with the isolation and climate control capabilities of greenhouses, these systems not only enable the automation and intelligence of agricultural production, but also play a crucial role in regulating seasons, protecting crops from extreme weather events, and ensuring optimal growing conditions. In this paper, a comprehensive control system for an intelligent greenhouse was designed, with Mitsubishi PLC and MCGS as the core components, based on the specific growth requirements of plants. The system consists of two main parts: hardware and software. The researchers constructed an advanced control system using a range of sensors and control devices, utilizing a typical PID control algorithm to maintain ideal growing conditions for plants. This research highlights the importance of intelligent greenhouse systems in modern agriculture and presents a promising solution for optimizing crop growth and yield through advanced automation and control.

Analysis of CO2 reduction with micro CHP facility: Renewable energies and Stirling engine

The Cogeneration laboratory is a research facility in the University of Málaga (UMA) that allows for the behavioural study of a renewable energy installation combining solar resources and micro-CHP. Energy generation in the system is provided by a 3 kWp photovoltaic array, two solar thermal connectors and a Whispergen EU1 Stirling micro-CHP unit. Energy storage in the facility is provided by water tank and lithium-ion battery. This laboratory is managed through a programmable Mitsubishi PLC that permits the simulation of different thermal and electrical load profiles, as well as the mode of operation. The electrical energy management is controlled by the solar inverter. Environmental data, are measured using a top of the line weather station.The system’s real time status is logged through the programmable PLC. All this data is transferred and analysed in a purpose-built MATLAB-based software, where power and energy balances are conducted, efficiencies are calculated, and a CO2 emissions evaluation is studied.The CO2 emissions analysis is carried to evaluate the carbon dioxide emissions generated by the facility when the electrical and thermal demand are provided by the joint solar and micro-CHP system. These emissions come from the burning of natural gas in the micro-CHP Stirling engine, and the usage of electricity from the grid. With the current mode of operation, a reduction of up to 70% in CO2 emissions has been achieved, with an energy generation that exceeds the demand.

Performance Investigation of PLC Hardware for Portable Two-Wheeler Dynamometer Test rig

The dynamometer is an instrument used for torque, force and velocity measurements. In a two-wheeler dynamometer frame, that is the easiest thing to use. So, until now, the testing has been held in the same place, but doing something new is making the whole system portable and being able to carry it anywhere. Therefore, PLC should be used to measure the parameters for input purposes, as many types of PLC are available. The machine is then connected to SCADA for an additional point. In order to monitor the working of the two-wheeler chassis dynamometer, the sensor is also used in the device and can changed the parameters.The entire dynamometer will be controlled using PLC and HMI (human-machine interface). Like the Sensor Actuators, it can integrate the device with the hardware. I decided to go with Mitsubishi PLC for this research because it has all the specifications I need and the cost that makes this a cost-effective system is lower. The effects of all the parameters are displayed on the HMI panel. For the sensors of the test rig, the simulation was developed and 3 percent of errors were identified compared to the results of the simulation with the data sheet.

Ladder diagrams are programmed by software to monitor the system and help improve public transportation services, thereby improving traffic guidance and traffic light control. The system was developed by setting the appropriate time for the traffic lights to respond accordingly. Critical timing operations should be performed during heavy traffic. The system used in traffic control systems must contain low power consumption, low engineering costs and increased safety. The controller then checks the priority and then provides an exit signal to the traffic light post to turn the red, yellow or green lights on or off, and the running time depends on the specific priority. Finally, the signal lights were successfully controlled by the PLC.
