For AlzChem, the use of one single engineering tool to configure the entire system simplifies engineering and saves a significant amount of time during commissioning.
With the old PLC solution, the program was not transparent
AlzChem in Trostberg, a subsidiary of Evonik Industries AG, produces specialty chemicals products with a wide range of uses. These chemicals are used, for example, in the production of crop protection products, pigments, dyes, pharmaceuticals and polymers.
In the past, an inverted filter centrifuge in a system for extracting natural substances was PLC-controlled at AlzChem. The program code for the PLC, a standard program from the manufacturer, was not transparent and needed specialists to make changes. The program was not intuitive and diagnostic analyses were only available to a very limited extent. In order to simplify programming and to optimize the process control, AlzChem thus decided to use the AC 700F controller. This replaced the PLC and was integrated into the existing Freelance DCS.
Now, the system is easy to understand and maintenance is simple
