Lack of continuity in terms of energy and raw materials mean that many municipalities for years dreamed of independence and predictability. The city lies in the Allgäu Alps Marktoberdorf is there a step further. Already since 2009 operates the district heating Marktoberdorf GmbH its own district heating network. The goal is a sustainable, environmentally friendly and economical heat supply of parts of the city and its citizens. Are powered public buildings such as Hall and indoor swimming pool as well as many private households.
At first the heat was purchased from local industrial plants, the operating company began to build in 2012's, perfectly matched to the demand characteristics of the customer care systems. In the expansion and the decision was made, to be monitored by a central process control system to operate the plant. "The system selection FlowChief convinced right away." So Mr. Markus Hacker - Head of Technology at the district Marktoberdorf GmbH. "FlowChief fulfilled not only the central tasks required of us as visualization, alerting or historicizing. We use the integrated maintenance and service management also functions that are not available on the range of current process control systems usually. "
With the implementation of FlowChief system integrator Zach was commissioned electrical equipment. The first task was the interfaces of the generation systems, heat meters, water meters and transfer stations and their protocols M-Bus, Modbus, Profibus and BAC-Net to bring to a common denominator. These decentralized controller Beckhoff were installed. These serve as a protocol converter and communicate to the brim with over Ethernet FlowChief.
Important decentralized locations were also equipped with a HMI solution from FlowChief. If the central control is not available, so suburb are still accessible to the process. "The engineering for this has already been run on the server. Process images and variable configuration had to be only copied "as Tobias brings Zach - Head of Automation Technology at Zach electrical equipment - a significant advantage to the point. By the way the end user uses identical user interfaces in the central and suburban.
- Process Control System 25.000 process variables
- Steadily growing heating network can be expanded by operators in the visualization of a button
- 2 FlowChief HMI decentralized suburban stations
- Alarm and Escalation Management (Dynamic alerting via SMS)
- Online coupling of 6 Beckhoff controllers that serve as a protocol converter
- Management with FlowChief maintenance management
