MES Software: Plex MES Suite

Drive plant floor efficiency with high-resolution visibility, error-proofed control, and a real-time production ecosystem that is connected to your ERP—by design.

Take Control of Your Plant Floor

ERP systems weren’t designed for manufacturing execution. Plant floor information available post-production—or “back-flushed”—doesn’t help you control output at the manufacturing moment. Plex’s Manufacturing Execution Suite (Plex MES) gives you real-time production management so you have up-to-the-second manufacturing data—for end-to-end visibility and closed-loop control.
