PLC and scada system application in a construction chemicals manufacturing plant

Industrial automation systems have been securing their position in the sector day by day. PLC-SCADA systems are frequently used in various fields of industry as they have many advantages like cost reducing solutions, standard product output, minimized error rate, availability of receiving real-time statistical and instantaneous data, operation efficiency and automatic control. In this study a medium sized construction chemical plant is monitored with SCADA system and its automatic/manual control is provide by PLC command system through SDACA. SCADA program used is Reliance Design 4 and PLC program is ABB Control Builder Plus. Computer communication is through Ethernet. The number of total tag used in the system is 68. This study can be divided into 3 sections. In the first section general information on PLC, its definition, history, structure and programming languages is provided. In the second section SCADA definition, its advantages and areas of usage and structure were our focus in general. In the third and final section general information on construction chemical plants, detailed information on the software and hardware used in the study and how the system works can be found step by step. As a result with the automation system obtained, the amount of product produced in an hour and a daily slice of the facility, the amount of electricity consumed and number of workers in the facility has has been compared with the predicted values for the system having no automation.
