AUTOMATION OF THE MILK PROCESSING TECHNOLOGICAL PROCESS BASED ON A PROGRAMMABLE LOGIC CONTROLLER VIPA

Modern requirements for automation of technological processes address a wide range of issues, ensuring the quality of technological operations.Currently, with the rapid development of microprocessor technology, the market for industrial automation tools is diverse, allowing the selection of control elements to meet any requirements of the technological process.The article discusses the application of the laboratory stand "Algorithm Testing on Simulation Models of Technological Processes," which allows testing and error detection during the development and implementation of automation systems for technological processes based on programmable logic devices.The process of developing, testing, and implementing the algorithm of operation for an automated milk processing line using programmable logic controllers is considered.These controllers provide the implementation of both classical work algorithms and the realization of non-standard solutions based on the use of fuzzy logic rules.The developed algorithm considers the sequence of performing technological operations with monitoring the execution of all stages and, in case of non-compliance with the technical task or occurrence of execution errors, blocks the next stage until the corresponding control element functions properly.The developed algorithm for controlling the milk processing line is implemented in the WinPLC7 environment, and examples of its operation are provided.This laboratory stand allows simulation modeling of other technological processes, enabling the acquisition of necessary competencies and skills for developing control algorithms, testing proposed solutions in the WinPLC7 environment, and implementing automated control systems for technological processes based on VIPA programmable logic controllers.
