Representative project scenario
Multi-Motor Production-Line Controls Modernization
Coordinate PLC, HMI, and multi-motor drives while preserving a recoverable conversion plan.
Illustrative setting: Building-products manufacturing · Goshen, Indiana
Representative project concept. This is an illustrative planning scenario, not a documented customer installation. Locations describe example settings. Figures are illustrative targets, not measured DES results or performance guarantees.
The example challenge
The representative line uses an obsolete PLC, discontinued variable-frequency drives, and separate operator controls. Uncoordinated speed changes affect material flow, while limited diagnostics require maintenance to investigate devices individually.
Operating and shutdown constraints
The example allows a 36-hour weekend shutdown. The original controls must remain recoverable until the replacement system passes functional testing.
A proposed approach
A proposed approach would assemble and test the replacement panel before the outage, then use a documented point-to-point conversion plan. A coordinated HMI would bring line-speed control, drive status, motor faults, permissives, and operating conditions into one operator interface.
Illustrative targets and handover
Planning examples only. These figures are not measured customer results or a promise of performance.
- Illustrative conversion duration: 31 hours within a 36-hour window
- Illustrative schedule allowance: five hours before planned production release
- Illustrative line-speed variation target: within ±0.2%
- Illustrative changeover-time reduction target: 18%
- Illustrative drive-troubleshooting-time reduction target: approximately 60%
- Follow-up plan: track drive-related production stops over six months
