Vending Fleet Control & Telemetry
UK dairy vending operator · vending & industrial software
The Challenge
An operator running 18 milk and milkshake vending machines across four counties had inherited them as sealed units: Weintek touchscreens and Siemens S7-1200 controllers with no source files, a know-how-protected PLC program, and no way to change a screen, a price or a cleaning cycle without the original supplier. Every fault meant a drive to the machine.
Our Solution
We extracted the HMI project from a panel on site, decompiled it in EasyBuilder Pro and recovered the full 687-tag address map. We rebuilt the touchscreen software (21 screens, zero compile errors, verified end to end in the simulator) and re-implemented the controller logic in TIA Portal, validated against a simulator of the original machine, staged for commissioning under the operator's sign-off. Using only the remote-access service the panels already had, we then pulled live temperatures and dispense counts from all 18 machines into one operations dashboard with an alert system tuned to how each machine actually behaves.
