Degrémont, a key player in
water treatment and sustainable development, uses ControlBuild IEC
61131-3 based software suite to optimize development efficiency
Degrémont, part of the SUEZ group, is an international water treatment plant specialist. Making water drinkable, no matter what the initial quality of the resource (such as groundwater, borehole water, brackish water or seawater), is Degrémont's specialty. Their focus ranges from ozonation and filtration with activated carbon, to the removal of mineral and organic micro contaminants.
Degrémont has decided to use ControlBuild IEC 61131-3 based software suite to optimize the development, maintenance and operation cost of filtering installations. Filtration is carried out in several filters running parallel to each other, constituting a battery of filters (see figure. 1).
Figure. 1 - Description of a filtering structure
ControlBuild is used to develop the complete filtering application by assembling standard modules of filters. These modules are intended to be instantiated on different PLCs (Schneider, Siemens, Rockwell…) all optimized to utilize the standard programming language of IEC 61131-3. The structure and breakdown of the application has been specially designed to enable centralized or decentralized PLC architecture. It also simplifies supervision tools and operator interface configuration.
Main benefits of ControlBuild as a PLC independent Software based on IEC 61131-3
Benefits of ControlBuild over PLC's programming software
Interfacing level between ControlBuild and PLC's development Software
This application example emphasizes the importance of the independence of the development environment from hardware. The use of XML as the exchange format advocated by the PLCopen Working Group TC6, ensures the sustainability of industrial control applications.
