About
Plex Systems is a cloud-based manufacturing ERP (Enterprise Resource Planning) and manufacturing execution system (MES) platform designed specifically for discrete and process manufacturers — providing production management, quality control, supply chain visibility, inventory management, and shop floor operations tracking in a single cloud platform. Founded in 1995 and headquartered in Troy, Michigan, Plex was acquired by Rockwell Automation in 2021 for $2.2 billion, becoming the software cornerstone of Rockwell's "The Connected Enterprise" smart manufacturing strategy.\n\nPlex's manufacturing cloud platform connects the production floor to the front office — tracking work orders, machine performance, quality inspections, lot traceability, and labor hours in real time. The MES capabilities provide production supervisors with live visibility into each workstation's throughput, scrap rates, and downtime, while the ERP layer handles procurement, inventory, shipping, and financial integration. The platform is used heavily in automotive supply chain manufacturing, food and beverage processing, and industrial manufacturing.\n\nIn 2025, Plex operates within Rockwell Automation (NYSE: ROK) as part of the Software and Control segment, integrating with Rockwell's industrial automation hardware (PLCs, drives, HMIs) and Factorytalk analytics platform. The manufacturing ERP market competes with SAP S/4HANA (manufacturing modules), Oracle Manufacturing Cloud, Infor CloudSuite Industrial, and specialized MES vendors. Plex's 2025 strategy emphasizes its integration with Rockwell's Logix control systems for closed-loop quality management, expanding in the food and beverage vertical, and growing its analytics capabilities for OEE (Overall Equipment Effectiveness) optimization.
