Plex is a cloud-native smart manufacturing platform acquired by Rockwell Automation in 2021, combining MES and manufacturing ERP for discrete manufacturers.
Definition
Plex is a cloud-native smart manufacturing platform that Rockwell Automation acquired in 2021. It combines MES, ERP-adjacent functionality, and quality management in a single SaaS platform, targeting mid-to-large discrete manufacturers. Its cloud-native architecture sets it apart from most legacy MES platforms that were built on-premise and retrofitted for cloud deployment.
What this means when you're hiring
Plex roles appear frequently in automotive supply chain, food and beverage, and industrial manufacturing. Rockwell's acquisition means Plex is increasingly positioned alongside FactoryTalk in Rockwell's broader connected enterprise pitch. Candidates who understand both the MES capabilities and the cloud ERP components are the most sought after, particularly at manufacturers replacing legacy on-premise ERP and MES simultaneously.
