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.

About
Cummins Inc. is a Columbus, Indiana-based power technology manufacturer — publicly traded on the New York Stock Exchange (NYSE: CMI) as an S&P 500 Industrials component — designing, manufacturing, and distributing diesel, natural gas, electrified power, and hydrogen power solutions for commercial trucks, buses, construction and mining equipment, generators, rail, and marine applications through approximately 73,000 employees in 190 countries and territories. In fiscal year 2024, Cummins reported record full-year revenues of $34.1 billion (flat versus 2023), record net income of $3.9 billion ($28.37 diluted EPS), and record EBITDA of $6.3 billion — an exceptional performance given a significant decline in heavy-duty truck build rates in North America, demonstrating the benefit of geographic diversification and product breadth across power segments. Results included gains from the 2023 separation of Atmus Filtration Technologies (NYSE: ATMU) as an independent public company. CEO Jennifer Rumsey — the first female CEO of a major engine company in US history, who assumed leadership in 2022 — leads Cummins' strategic evolution through its Destination Zero strategy: achieving near-zero carbon emissions from Cummins products by 2050 through a portfolio of diesel, natural gas, hydrogen internal combustion engine, hydrogen fuel cell, and battery electric power solutions that allows customers to decarbonize at their own pace based on fuel availability, infrastructure, and economics. Cummins' Accelera (electrification) business unit develops battery systems, fuel cell modules, and e-axles for the zero-emission commercial vehicle transition.
