Control system of Schneider Meat Processing Plant, Pilsen

The Schneider Meat Processing Plant is among the largest producers of meat products in the Czech Republic. The company was founded in 1989. 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 whole SCADA-based control system consists of two PLC devices (Tecoreg TR300 and Tecomat TC600) and the Reliance SCADA/HMI system. The whole installation was carried out by the Czech company Tecont s.r.o. Reliance software is installed on the control computer located in the control room. Reliance provides control and visualization of the production technology and operation conditions of the Schneider Meat Processing Plant.
