Jensen Jenscan retrofit: legacy HMI obsolescence in hospitality & NHS laundries
NHS Cyber Essentials & DSPT: Windows XP/7 is a compliance blocker
NHS trusts must pass the Data Security and Protection Toolkit (DSPT) annually. Networked Windows XP/7 systems are automatically non-compliant. A Jensen Jenscan station connected to the hospital LAN is a direct finding. DSPT submission deadlines are fixed. Plan the upgrade before the next assessment window.
Jensen Group (Ghent, Belgium) remains an active manufacturer of industrial laundry equipment, but the JENSCAN linen tracking and sorting systems installed in the late 1990s and 2000s run on Windows XP or Windows 7 workstations with proprietary Jensen software and Siemens S7-300 PLCs. These are no longer patched, no longer compliant, and increasingly hard to keep running. GCG replaces the Jenscan HMI platform, the underlying S7-300 controller, and the barcode/RFID readers with a modern stack, while preserving all existing linen tracking data and category configurations.

Technical architecture: what makes this obsolete
Windows XP/7 Jenscan workstation
Proprietary Jensen JENSCAN software (32-bit, SQL Server 2003/2008 Express). No security patches since 2014 (XP) / 2020 (7). Any connection to hospital or hotel LAN creates a live vulnerability. No vendor-supported upgrade path exists. Jensen has moved to a new platform.
Siemens S7-300 / Bosch PLC
S7-300 CPUs (315/317) reach Siemens service lifecycle end in 2023. Spare modules available but shrinking. Bosch controllers used in some THERMOTEX ironers are even harder to source. PROFIBUS DP fieldbus: no PROFINET diagnostics, no remote access.
Barcode / early RFID readers
First-generation RFID transponders (125 kHz EM4100) and CCD barcode wands are no longer produced. Replacement requires full reader hardware refresh. Modern ISO 15693 / 14443 (HF 13.56 MHz) RFID is incompatible with legacy tags. Linen retag or parallel migration required.
Isolated system, no integration
Jenscan has no REST API, no SOAP interface, and no standard export for integration with modern Laundry Management Systems (LMS) or hospital ERP. Reports are generated as proprietary file formats. Manual data entry downstream is the only option.
Installed base: UK, Ireland, and Netherlands
London & South East
NHS acute trusts (Barts, Kings, Imperial), private hospital chains (HCA UK, Spire, Nuffield), large hotel laundries (Marriott, IHG properties).
Manchester & North West
Manchester University NHS Foundation Trust, Salford Royal, Premier Inn/Travelodge laundry suppliers, workwear rental (Berendsen/Elis UK).
Dublin & Ireland (HSE)
Health Service Executive (HSE) hospital laundries, Beacon Hospital, Mater Private, Dublin hotel-laundries (Radisson, Hilton, Intercontinental).
Migration platform: S7-1500 + modern HMI + LMS integration
GCG replaces the Jenscan workstation with a Windows 11 server running a modern linen tracking application, replaces the S7-300 with an S7-1500 via TIA Portal, and installs new HF RFID or 2D barcode readers. An optional REST API layer connects the new system to existing LMS or hospital ERP.

Migration steps
- 1
System audit & data export
Full export of linen categories, item counts, and tracking history from the Jenscan SQL database. S7-300 program backup via STEP 7. RFID/barcode reader inventory. Compliance gap analysis (DSPT / Cyber Essentials).
- 2
New HMI/server engineering & S7-1500 chassis
Windows 11 server specification, linen tracking software configuration, S7-300 → S7-1500 I/O mapping, PROFINET network plan, new RFID/barcode reader selection and cabling plan.
- 3
TIA Portal programming & FAT
STEP 7 to TIA Portal conversion, WinCC Comfort HMI screens, PROFINET drive/reader integration, linen data import into new tracking system, Factory Acceptance Test including DSPT evidence documentation.
- 4
SAT + staff training + compliance handover
On-site commissioning, linen tracking verification, staff training for laundry operatives and IT teams, DSPT/Cyber Essentials evidence pack, 4-week hypercare support. Downtime: typically 48–72 hrs (Jenscan + one line); 72–96 hrs for multi-line installations.
FAQ
Is Jensen Jenscan still supported by Jensen Group?
Jensen Group has moved to a new generation platform. The legacy Jenscan software (Windows XP/7-based) and the associated S7-300 / Bosch controllers are no longer in Jensen's active support portfolio. Hardware spare parts for the legacy readers are increasingly sourced from the secondhand market.
What are the NHS DSPT requirements for laundry systems?
The DSPT requires all networked systems to run supported operating systems. Windows XP and Windows 7 are unsupported and generate an automatic non-compliance finding if network-connected. The annual DSPT submission deadline is June 30. GCG provides an evidence pack as part of the project deliverables.
Can we keep our historical linen tracking data?
Yes. GCG exports all data from the legacy Jenscan SQL database, linen categories, item profiles, wash cycle counts, and historical tracking records, and imports them into the new tracking system. The data migration is validated before go-live.
What does the project cost?
A single-line Jenscan HMI and S7-300 migration costs EUR 20,000–32,000 including engineering, hardware, data migration, and commissioning. Multi-line or multi-site projects: EUR 30,000–55,000. Exact quote after system audit.
How do we handle the RFID tag incompatibility?
GCG assesses the installed RFID tag type. Where existing tags are functional but on 125 kHz EM4100, we implement a dual-frequency reader that supports both legacy and new tags during the transition, allowing a rolling linen retag over the normal replacement cycle rather than a forced mass retag.
