The Problem
What the plant was facing
Every machine on the line had its own local recipe list. Changes were made on the HMI without traceability, causing inconsistent product across machines and disputes about who changed what.
Our Solution
What we engineered
- Central recipe database with versioning and approval workflow
- One-click recipe deployment to selected machines
- HMI recipe browser with product code lookup
- Full audit trail: who changed, what changed, when
- Recipe rollback to any previous version
