SCADA project for milk evaporation in double-effect evaporators

Human-machine interface tools remain one of the components of production automation systems. Appearance and functional abilities cannot stand still in the same way as automation, in this regard, one of the important aspects of food production automation is highlighted in this paper - a human-machine interface aimed at improving the operator's workplace. At the dispatcher level of automation, it is necessary to provide for the solution of the entire range of tasks set during the implementation of this project. The objectives of the project are to reduce the time for decision-making by personnel, since the effectiveness of the enterprise partially depends on the speed of the task, notification of hazards and violations, as well as the prevention of emergency and abnormal situations during the evaporation of milk, storage and archiving of data on the course of the process necessary for the preparation of reports used to investigate the causes of any emergency when evaporating milk. The project of the human-machine interface of the milk evaporation process, developed in the TRACE MODE environment, is presented. A feature of TRACE MODE is the technology of a single programming line, that is, the ability to develop all the ACS modules using a single tool. In the developed project of the human-machine interface of the milk evaporation process, it is assumed to use two main operator stations and one backup. Two of them are for operator workstations and a backup one used in emergency situations. The developed project in the TRACE MODE environment makes it possible to improve the workplace of the operator of the vacuum evaporation plant, reduce the time required for response and decision-making by personnel. In addition, the automatic alarm system allows you to reduce the number of defective products, and, accordingly, increase output and reduce the cost of production per unit of raw materials. The developed project fully satisfies the technical task and has been put into production.
