Manufacturing Execution System (MES) / MOM Software

Take control of your plant floor with full visibility into your production lifecycle and full connectivity to your manufacturing ERP with a MES system from Plex.

What is a Plex MES System?

Plex MES (Manufacturing Execution System) is a cloud-based production management platform that gives manufacturers full visibility across the plant floor and real-time control over production lifecycle. Plex MES features operator control panels, error-proofed workflows, closed-loop quality control, inventory tracking, and finite scheduling, all aimed at reducing errors, increasing efficiency, and improving quality. By connecting tightly with ERP systems and providing unified, real-time data, Plex MES helps manufacturers achieve compliance, traceability, and consistent performance across operations.

Benefits of Plex MES Software

Plex MES System Capabilities

Gain more reliable data for effective decision-making

In many plants today, people still manually enter much of their data. Plex’s paperless, easy-to-use operator Control Panel automates tasks, preventing human errors and increasing productivity. Plant operators can mitigate compliance risk through database-driven traceability and direct, in-line quality control.

Empower both your top floor and plant floor to finally work from the same real-time data

Traditionally, MES/MOM systems contain disparate applications connected through complex integrations. Plex provides a unified MES manufacturing software solution — that means a single user interface to applications that are designed to work as one. And because the Plex MES platform is in the cloud, you can access your full production lifecycle from anywhere, at any time, on any connected device.

Respond to market demands or customer changes without interrupting production

Changes from the top floor plan are dispatched to the plant floor scheduler. For every action on the plant floor, there is a transaction in Plex. Our flexible, configurable cloud MES system is also easy to deploy, standardize across your enterprise, and connect to your corporate ERP.

Aligned with extreme precision to the pillars of Smart Manufacturing.

Plex MES/MOM Systems are designed to provide immediate value for your company, while preparing you for whatever tomorrow brings.
