Modern SCADA systems in production of soy flour and grits and textured soy proteins

This paper describes the SCADA (Supervisory Control And Data Acquisition) software in the plant for production of soy flour and grits and textured soy proteins (TSP), which relies on PLC (Programmable Logic Controller). Six touch panels in the field are networked with two PC's in control room and together make a system that on one side communicates with the PLC and on the other side allows operators access to all parts of the plant. The additional features of software are: the alertness to the possible excesses of the system via alarm messages, the graphical representation of tags in form of a tables or trends, archiving information in a database, creating reports, etc... The software is designed with the suggestions of operators who have extensive experience in the management of these plants. The software was tested and put into operation in the factory 'Soyaprotein' in Becej, Serbia.
