Safety controller takes over Scada
system
Global competition as well as the growing need for change in the installed process control systems meant that Degussa Initiators had to rethink the technical realisation of its entire OP operation.
Global competition as well as the growing need for change in the installed process control systems meant that Degussa Initiators had to rethink the technical realisation of the entire OP operation (organic peroxide) at its production site at Pullach Degussa commissioned Kiel Engineering to create the automation concept, the 40 application programs including the visualisation programs and also to provide support during commissioning

Safety-related controllers provided by Hima Paul Hildebrandt are used to monitor a range of PLT protective equipment in Bayer MaterialScience's new TDA production plant at Dormagen.
Safety controller drives asset management system
Hima Paul Hildebrandt has combined its H51q safety controller, with the H 6200 intrinsically safe analogue isolator and the H 6210 Hart multiplexer to form an asset management system.
Hima Paul Hildebrandt delivered the hardware and provided support during the concept design.
To ensure the necessary high plant flexibility, a process control system was not used.
Instead, the decision was taken in favour of a new extensive automation concept based on a safety-related control system to monitor, control and regulate all the safe and non-safe automation circuits as well as a higher-level Scada system to operate and observe these regulation and control circuits.
In the production units concerned, a total of 15,000 process variables must be checked or controlled for process monitoring and automation purposes.
All control and regulation tasks are implemented using the most powerful member of the Hima family of safety controllers, the H51q.
In the safety controller, which is approved to SIL3 without restrictions, not only all the production programs, but also all the recipes are permanently loaded.
Furthermore, the common raw material supply is automated with a H51q.
The success of the Hima safety system and "Scada system" project planning at Degussa has shown that, even in larger-scale projects with up to 15,000 process variables, it is possible to achieve an automation potential, which is in many aspects equal to that of a standard process control system.
The automation concept has fully met the expectations with regard to "safer" production processes, increasing the system availability and cost optimisation. Request a free brochure from Hima Paul Hildebrandt ...
