The document details the controller modernization at Bad Dürrheimer Mineralbrunnen, replacing obsolete Texas Instruments TI 555 hardware with Siemens SIMATIC S7 and ProLeiT Batch iT. The upgrade addressed capacity limits from expanded product ranges and eliminated hardware obsolescence risks. Key functions implemented include flexible recipe management per ISA-88, real-time batch tracking via barcode scanning, residual quantity handling with automatic recipe adjustment, and integrated materials management across the syrup room.

Key takeaways

Legacy TI 555 controllers replaced in five days using Siemens S7 and ProLeiT Batch iT without rewiring field devices

Batch tracking achieved through barcode scanning of all raw material containers and container relocations

Residual quantity management automatically adjusts recipes based on actual metered stock levels

Flexible recipe parameters support variable metering sequences, pump speed ramps, and viscosity handling

Plant-wide integration via Plant Acquis iT enables order-, batch-, and shift-based production data access
