Summary

Plex MES is a cloud-based production management platform for controlling production and giving teams a real-time view of plant-floor activity. It tracks materials from receipt through work in process to shipment, and includes work order management, inventory tracking, shop-floor data capture, dashboards, and lot and serial traceability. Operators have control panels and error-proofed workflows; quality teams can manage procedures from control plans through closed-loop quality management. Its finite scheduling engine assigns jobs to work centers based on resource availability. Deployment options range from cloud-native operation to a fully resilient edge, and flexible APIs connect external systems. Plex MES is designed to connect to corporate ERP systems, with integrations documented for SAP and Oracle. Plex states that it is ISO 27001:2013 certified, protects data in transit with TLS 1.3 or higher and data at rest with AES-256, and replicates customer data across primary and secondary tier 5 data centers. Pricing is on request; the Manufacturing Execution Suite is described as one low annual subscription fee, with unlimited users and machines and no overage charges.
