Control Systems

Each feed mill's manufacturing process is fully automated using the complete suite of InFeed 600 systems and products. The user interface hardware consists of a domain server with various user client PCs, all running under Microsoft platform. The process control hardware is a series of networked Mitsubishi PLCs, which directly interface with and control the plant equipment.

The various layers of the system consist of a user front end (GUI), SCADA software engine, reporting software and PLC process control software. The GUI is developed using AFCON Inc. HMI SCADA PCIM. The InFeed 600 MES engine, which processes, stores and manipulates data and communications with PLCs, weigh bridges, ERP, MIS platforms, consists of numerous C/C++ programs and modules, all of which have been developed exclusively by ICM Computer Systems as part of its ongoing product development for the agri and aqua food manufacturing industry.

Each feed mills InFeed 600 system is fully integrated with the client's corporate ERP system MOVEX, which communicate with each other using customised API protocols. The ERP schedules raw material deliveries and production/BOM requirements that are routinely downloaded to InFeed 600. InFeed 600, which is integrated with the goods in weighbridges controls, records and reports all raw material deliveries. Blending and process raw material usage/variance transactions are recorded by InFeed 600 and reported to the ERP system real time. Completed and packaged finished product and waste transactions are also recorded and reported to the ERP system real time.

Each bag of feed produced is labelled with its own unique label detailing manufacturer data, product name, manufacturing order number, batch/run number, bag number, pack size, ingredients, and nutrient information, feeding instructions, date of manufacture and best before date.
