Due to brisk shipping traffic, the requirements placed upon the flood barrier's operational safety are extremely high. This necessitates the processing of very many safety queries by the line controls as well as their communication with each other.
Spanning a length of 145 meters, the Billwerder Bucht barrage ranks among Germany's largest flood barriers. It connects the district of Rothenburgsort with the Elbe island of Kaltehofe and not only protects port facilities and adjacent industrial areas, but also a power plant.
S7-1500 controllers are used for line control. They are interconnected via Scalance Profinet switches with redundant power supply.
"The smoothness of the commissioning process with Simatic S7-1500 and the TIA Portal was hitherto unprecedented." Michael vor den Brocke, Project Manager at HPA

Conversion from S7-300 to S7-1500 entailed only few mouse-clicks. Migration was already successfully completed after 10 minutes.
Simatic S7-1500 and the TIA Portal offer state-of-the-art technology. At the same time, HPA is able to rely on a long runtime without system changes.
The Excel mass fstaunctions integrated in Step 7 saved a great deal of time in the creation of data blocks with numerous variables. Using the auto-complete funzction with pressed mouse-button, rows of variables can be created in a rapid and fault-free manner. Also user-defined, individually created data types facilitated time savings in terms of configuration and commissioning: They are created globally in the project; for reuse, they need not be copied, but merely called up. Non-recurring changes to these data types are automatically and consistently updated throughout the project.
