  • PLC/SCADA Systems in Automation Control Design for Individual Quick Freezing Process in Cooling Tunnels
    PLC/SCADA systems in automation control design for individual quick freezing process in cooling tunnels Goran Jagetić, Marko Habazin, Tomislav Špoljarić University of Applied Sciences - Department of Electrical Engineering, Zagreb, Croatia [email protected], [email protected], [email protected] ABSTRACT - Individual quick freezing process is a two periods of operation: refrigeration period and complex cooling process that takes place in cooling defrosting period. Refrigeration period is longer and tunnels and is used for dynamic thermal processing of in it refrigeration elements (compressor, condenser certain type of goods. Type of goods and temperature and evaporator fans) are switched according to room of goods that needs to be achieved over specific time in temperature probe/probes. Defrosting period is much cooling tunnel determine the complexity of cooling process. Complex cooling process is therefore divided shorter and in it defrosting elements (electrical into two types of regulation. Temperature regulation, heaters/hot gas valve) are switched according to the inferior type, is used for control of the cooling and evaporator temperature probe or by time (off- defrosting parts of the system according to predefined delayed timer function of a regulator). Fig. 1 shows room temperature. Superior time-cycle regulation is simplified block diagram of a small scale used to control various cycles of operation by defining refrigeration system operated by one-cycle its time frames. These cycles together form a period of regulation (refrigeration with defrost). time in which the cooling system is appropriately used for goods' freezing. This paper describes further development in automation control design for complex cooling process in cooling tunnels.

  • Semantic Analysis of Ladder Logic
    Semantic Analysis of Ladder Logic A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Soumyashree Gad, M.S. Graduate Program in Computer Science and Engineering The Ohio State University 2017 Master's Examination Committee: Dr. Srinivasan Parthasarathy, Advisor Dr. P. Sadayappan c Copyright by Soumyashree Gad 2017 Abstract Purpose: A careful examination of Ladder Logic program reveals it's hierarchical nature and components, which makes it interpret able. Perhaps, using data mining techniques to interpret the top level and sub-level components can be really useful. This seems like a classification problem. The application of machine learning algo- rithms on the features extracted from ladder logic can give insights of the whole ladder logic code. The components and their interactions are intuitive which certainly add to the probability of getting better results. The learning in the PLC programming can be alleviated by converting the existing PLC code to commonly used formats such as JSON, XML etc. The goal is to consume ladder logic sample, break it down into minor components, identify the components and interactions between them and later write them to JSON. As Ladder logic is the most commonly used programming language for PLCs we decided to start the experiment with Ladder logic program sam- ples. Feature engineering combined with machine learning techniques should provide accurate results for the Ladder Logic data. Methods: The data set contains 6623 records for top level classification with 1421 ALARM, 150 STEP SEQUENCE, 96 SOLENOID samples and 5304 UNCLASSIFIED and 84472 records for sub-level classification which contains sub-level components of the all the ALARM and STEP SEQUENCE samples from the top level data set.

  • Ladder Programming Manual
    FT9Y-B1382 FT1A Series Ladder Programming Manual SAFETY PRECAUTIONS Read the SmartAXIS Pro/Lite User’s Manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and inspection of the SmartAXIS. All SmartAXIS modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or failsafe provision to the control system when using the SmartAXIS in applications where heavy damage or personal injury may be caused in case the SmartAXIS should fail. In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution: Warning Warning notices are used to emphasize that improper operation may cause severe personal injury or death. The SmartAXIS is not designed for use in medical equipment, nuclear power, railways, aviation, passenger vehicle equipment, or similar applications requiring a high degree of reliability and safety. The SmartAXIS cannot be used for such applications. When using the SmartAXIS in applications not described above that require a high degree of reliability in terms of functionality and precision, appropriate measures such as failsafe mechanisms and redundant mechanisms must be taken for a system containing the SmartAXIS. Emergency stop and interlocking circuits must be configured outside the SmartAXIS. If relays or transistors in the SmartAXIS output circuits should fail, outputs may remain in the on or off state. For output signals which may cause serious accidents, configure monitor circuits outside the SmartAXIS. The SmartAXIS self-diagnostic function may detect internal circuit or program errors, stop programs, and turn outputs off. Configure circuits so that the system containing the SmartAXIS is not jeopardized when outputs turn off.

  • Programmable Logic Devices (Plds) Lecture 1 Introduction to Micro-Processors and Micro-Controllers
    NPTEL – Mechanical – Mechatronics and Manufacturing Automation Module 3: Programmable Logic Devices (PLDs) Lecture 1 Introduction to Micro-processors and Micro-controllers 1. Introduction Programmable Logic Devices (PLD) are programmable systems and are generally used in manufacturing automation to perform different control functions, according to the programs written in its memory, using low level languages of commands. There are following three types of PLDs are being employed in mechatronics systems. 1. Microprocessor It is a digital integrated circuit which carries out necessary digital functions to process the information obtained from measurement system. 2. Microcomputer It uses microprocessor as its central processing unit and contains all functions of a computer. 3. Programmable Logic Controller (PLC) It is used to control the operations of electro-mechanical devices especially in tough and hazardous industrial environments. A typical programmable machine has basic three components as shown in Figure 3.1.1: 1. Processor, which processes the information collected from measurement system and takes logical decisions based on the information. Then it sends this information to actuators or output devices. 2. Memory, it stores a. the input data collected from sensors b. the programs to process the information and to take necessary decisions or actions. Program is a set of instructions written for the processor to perform a task. A group of programs is called software.

  • 2Basic Ladder Logic Programming
    2 Basic Ladder Logic Programming Chapter Topics: • Basic ladder logic symbols • Ladder logic diagram • Ladder logic evaluation • Start/stop logic OBJECTIVES Upon completion of this chapter, you will be able to: • Understand basic ladder logic symbols • Write ladder logic for simple applications Scenario: A program with a long scan time may not detect short-duration events. A manufacturer of small gasoline engines had an intermittent problem on the final assembly line. Sometimes, a defective engine would not be automatically removed from the line for repair at a “kick-out” station. If an operator noticed a problem with an engine, he/she inserted a bolt into a certain hole in the engine carrier. A proximity sensor before the kick-out station sensed the presence of the bolt, and the PLC activated a hydraulic solenoid to push the carrier (and engine) off the main conveyor and into the repair area. A view of this station is shown in Figure 2.1. Further investigation revealed that the duration of the on pulse of the proximity sensor was approximately 3/4 seconds. One PLC controlled all of the stations on the assembly line and its ladder logic program was quite large. As indicated in the PLC status, the time to scan the ladder logic program was slightly less than 1 second. Hence, it was very likely that a pulse from the proximity sensor could be undetected by the PLC processor. The proximity sensor could be off at the start of the ladder scan, generate an on pulse from a passing bolt in the carrier, and be off at the start of the next ladder scan.
