Client : South African Sugar Terminal
Duration : 6 Months
Budget : R1,200,000
The South African Sugar Association stock piles sugar from local sugar producers to be distributed locally and to international customers. The sugar is stored at the sugar terminal in piles across three silos which are visible and known as a landmark within the Durban harbor. This segregation of the sugar is done by capturing the quality of the sugar upon receipt with all the relevant information from the source mill including the date and means of transport.
CSS was tasked to design and supply new PLC and Supervisory system to control and monitor the SA Sugar Terminal material handling plant. This was based on Siemens S7-300 Range of PLC hardware with remote I/O. All remote I/O is connected via a redundant fiber optic Profibus ring network. The system will control the conveyor routing and control the molasses mixing plant to ensure export quality remains within set parameters.
The supervisory system is based on Wonderware Archestra technology and the Systems Platform form the core of the system. This comprises of the Application server where all devise object will be deployed and executed from in a peer environment, the Data historian for the logging of all data and plant equipment signals and conditions as well as production totals and information.
Operator interaction into the system is via InTouch view nodes some with diagnostic and reporting facilities to enhance and optimize plant production and efficiencies.
Reporting development is done using Active Factory and the reports both static and dynamic will be published to the Information Server for viewing across the network by the Information server clients.
Intake and export data is captured via the InTouch frontend and stored to a MSSQL database from where data is extracted to the plant LIMS. Intake and Export reporting is done using MS Reporting services.
