GMP washer control system retrofit

The buyer's problem

Legacy washer controls can make batch sequencing, audit-ready reporting and data backup harder to maintain. Replacing the automation should not erase established cleaning cycles or operator practice.

What we replace

• Obsolete PLC and HMI hardware with a current control and visualization architecture.
• Aging batch reporting and data-management components with agreed backup and redundancy provisions.
• Legacy sequence control that cannot support required auto/manual operating workflows.

What we retain where suitable

• The washer chamber, utility connections and serviceable mechanical systems.
• Approved cleaning recipes, cycle steps, limits and operating know-how.
• Plant historian, site network or reporting connections where compatibility and data governance permit.

Control platforms

• Siemens and Rockwell platforms, with customized visualization software (documented in the matching GMP washing machine case study).

Validation deliverables: FAT through PQ

Deliverables and responsibilities are agreed with your engineering and quality teams. PQ approval remains with the equipment owner.

• Pre-FAT / FAT: approved sequence, auto/manual, report and backup test protocols with execution records and deviations.
• SAT: installation and site-interface acceptance report against agreed washer requirements.
• IQ / OQ: installation checklists, functional test records, access/electronic-record evidence where applicable and requirements traceability.
• PQ: technical support for customer-approved cleaning-performance protocols, run records and training handover; cleaning acceptance remains with customer QA.

Matching project experience

The case study reports redundant batch report generation, tamperproof PDF reporting, auto/manual sequence options and a fastest handover of 15 days.
