The company INEA d.o.o. did a batching automation project for its client. The system is designed for testing different production procedures and consequently has to be as flexible as possible. Base of the system is represented by three positions, which can be configured with different tanks and system for temperature regulation.
This thesis presents implementation and operation of the system. System design is following the ANSI/ISA–88.01–1995 standard, which defines models and terminology for batch control systems. Programmatically, the system consists of three main parts. PLC project is created using Studio 5000 Logix Designer. Tool Batch Management is responsible for correct execution of a batch. SCADA enables supervisory control and data acquisition. Because flexibility of a system is a requirement, a configurable interlocks were introduced to provide safe response of equipment in case of process difficulties. Interlocks are recipe depended and are set at the beginning of batch execution. Because the system is intended for testing different production procedures, the client will make recipes on its own according to the needs. To ensure correct operation of newly created recipes, a simulation is also implemented. This way, a recipe can be safely and thoroughly tested without using physical equipment.
