Plex MES
What it is
Plex MES is a cloud-based manufacturing execution platform for managing production and monitoring plant-floor activity. It tracks materials from receipt through shipment, including work in process, to provide a real-time view of operations. Operators have control panels and error-proofed workflows; quality teams can manage procedures from control plans through closed-loop quality management. Other capabilities include inventory tracking, finite scheduling, work orders, shop-floor data capture, dashboards, and lot and serial traceability. Its scheduling engine assigns jobs to work centers while considering resource availability. Deployment options range from cloud-native operation to a fully resilient edge. An integration layer and modern APIs connect external systems, and Plex MES is designed to connect with corporate ERP systems, with documented integrations including 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. The product is pre-configured for discrete, consumer packaged goods, and regulated industries. Pricing is available on request; the suite is described as having one annual subscription fee, unlimited users and machines, and no overage charges.
