Visualization and control of the Schneider Meat Processing Plant in the city of Pilsen

The Schneider Meat Processing Plant is among the largest producers of meat products in Czechia. The company was founded in 1989. The construction of the production plant started shortly after its founding.

The Schneider Processing Plant was built at an undeveloped location at the beginning of the nineties. Today, Schneider produces a wide range of meats, smoked meats, and delicatessen. Cooked hams, smoked hams, sausages, and seasonal meat products are the most popular.

A new control system for the Schneider Meat Processing Plant was installed in 2004. The SCADA-based control system consists of two PLC devices by Teco (TECOREG TR300 and Tecomat TC600) and the Reliance SCADA/HMI system. The whole installation was carried out by the Czech company TECONT. Reliance is installed on the control computer located in the control room. Reliance provides control and visualization of the plant's production processes and operation conditions.

The Reliance system provides visualization and control of

Heating system and hot water supply system

• Boiler room – control of two hot-water boilers and four hot-water circuits
• Boiler room – control and visualization of two steam boilers and steam network
• Heating of hot water
• Steam heating of hot water

Air-conditioning system

• Control of the air-conditioning units used for the air-conditioning of the production areas
• Ventilation of the boiler room
• Ventilation of the machinery room (air compression)

Machinery room (cooling)

• Control of three York ammonia compressors
• Regulation of the ammonia level in the expansion tank
• Control of the pumps used for pumping the ammonia
• Control of the electric fans used for the cooling of the condenser
• Control of the cooling water pumps and heat exchanger used for the preheating of hot water

Cooling system

• Control of thirty cooling units mounted on the ceilings of the cooling chambers and production areas
• Measurement and indication of the temperature in the refrigerating rooms

Machinery room (air compression)

• Control and monitoring of the compressors

Further monitoring and measurement

• Redundant detection of ammonia leaks in the production and technical areas
• Control of power and water consumption

All the processes and systems mentioned above are visualized by the Reliance SCADA system. Every system has one visualization window. It gives operators the possibility to control a specific process in a well-arranged visualization window. Time programs are also displayed and controlled by Reliance. Data from the processes is stored in the Reliance database. Historical data can be displayed on an LCD display or printed. Reliance also provides displaying and acknowledging current alarms and events, which can be sent to any email or cell phone.
