Visualization and control of the processes at the Rohde & Schwarz waste disposal station

Rohde & Schwarz GmbH & Co. KG is a transnational company specializing in test and measurement, broadcasting, secure communications, radiomonitoring, and radiolocation.

Established more than 70 years ago, Rohde & Schwarz has a global presence and a dedicated service network in over 70 countries on four continents (North and South America, Europe, Asia). The company's headquarters is in Munich, Germany, where there is also one of their two production plants. The other is located in the Czech town of Vimperk.

Electronic and mechanical parts for measurement equipment, radiocommunication equipment, and parts for detection systems are manufactured in the Vimperk production plant. More than 400 employees produce a substantial part of the entire company's production portfolio. Most of the products are intended for export. The production plant in Vimperk has its own disposal station, which is used for the neutralization of wastewater from the electroplating line.

Control system

In 2004, a new SCADA-based control system with the Reliance SCADA/HMI system was implemented in the Vimperk production plant. The unmanned operation of the waste disposal station was the main reason for the installation of the new control system. The installation was carried out by the PROTECO company.

The control of the waste disposal station is provided by a Siemens SIMATIC S7-300 PLC. The Reliance system is installed on the control computer located in the control room. Communication between the PLC and the control computer is provided over the Merz OPC driver.

The Reliance SCADA/HMI system provides visualization and control of:

• Three input tanks used for the storage of wastewater
• Chemical reaction tank
• Sludge tank
• Filter tank used for sand filtration
• Water neutralization
