Reviewed by BizzContacts EditorialLast reviewed 2026-06-11

Plex Systems is the category-leading cloud manufacturing platform for automotive Tier 1 and Tier 2 suppliers and discrete manufacturing, with approximately 700+ manufacturing customers globally running Plex Smart Manufacturing Platform combining MES (Manufacturing Execution System), ERP, Quality Management System, Supply Chain Planning, Production Monitoring, and Asset Performance Management on a single cloud platform. Plex was founded in 1995, evolved into the dominant automotive Tier supplier MES/ERP, and was acquired by Rockwell Automation (NYSE: ROK) in 2021 for $2.22B. The Rockwell ownership is structurally significant: Rockwell is the dominant industrial automation provider (PLCs, drives, motion control, FactoryTalk) for North American manufacturing, and Plex provides Rockwell with the cloud manufacturing software layer (MES + ERP + QMS) that complements Rockwell's plant floor automation hardware. The platform spans Plex Smart Manufacturing Platform (the unified Rockwell-era cloud manufacturing platform brand), Plex ERP (manufacturing-first cloud ERP, formerly Plex Manufacturing Cloud, the strategic ERP for automotive Tier suppliers), Plex MES (Manufacturing Execution System, the category-leading automotive Tier supplier MES with strong shop floor connectivity and traceability), Plex Quality Management System (QMS for IATF 16949 automotive quality, AS9100 aerospace, FDA medical device, FSMA food safety), Plex Supply Chain Planning (SCP, post the DemandCaster acquisition for demand and supply planning), Plex Production Monitoring (real-time shop floor connectivity, post the 2021 DATTUS acquisition for direct machine connectivity), Plex Asset Performance Management (APM for predictive maintenance), Plex Maintenance Management, Plex Plant Floor Mobile, Plex Workflow Engine, Plex Customer Portal, Plex Supplier Portal, Plex APIs and Marketplace integrations, and integrated Rockwell FactoryTalk connectivity.

The BizzContacts Plex Systems customers list captures this automotive Tier supplier and discrete manufacturing cohort as a separately tagged segment, distinct from SAP S/4HANA (the enterprise ERP leader at https://bizzcontacts.com/installed-base/sap-s4hana/), Infor (CloudSuite Industrial, M3, LN at https://bizzcontacts.com/installed-base/infor/), Microsoft Dynamics 365 F&O (https://bizzcontacts.com/installed-base/microsoft-dynamics-ax/), Epicor (Kinetic, CMS for automotive at https://bizzcontacts.com/installed-base/epicor/), Acumatica Manufacturing (at https://bizzcontacts.com/installed-base/acumatica/), NetSuite Manufacturing (Oracle SMB), IFS Aerospace, QAD (process manufacturing competitor with automotive presence), DELMIAworks (formerly IQMS, Dassault), Global Shop Solutions (discrete manufacturing SMB), DELMIA Apriso (Dassault MES upmarket), Siemens Opcenter (Siemens MES upmarket), Aveva MES (Schneider), GE Digital Proficy (MES), Tulip (modern frontline operations platform), MachineMetrics (modern OEE), FactoryOS (modern MES), and modern manufacturing AI competitors (Augury for vibration, Uptake for asset performance, Senseye) audiences. We maintain 540+ verified Plex customer records with company firmographics, tagged Plex products in production (Smart Manufacturing Platform, ERP/Plex Manufacturing Cloud, MES, QMS, SCP/DemandCaster, Production Monitoring/DATTUS, APM, Maintenance, Plant Floor Mobile, Workflow, Customer Portal, Supplier Portal, FactoryTalk integration), Plex tier (standard, Enterprise, Multi-Plant, Multi-Subsidiary), automotive quality certifications (IATF 16949, AS9100, FDA 21 CFR Part 820, FSMA 21 CFR Part 117), industry vertical (Tier 1 automotive supplier, Tier 2 automotive supplier, Tier 3 supplier, OEM, food and beverage, aerospace, plastics, electronics, medical device, industrial equipment), and named decision-makers on every record (CIO, CTO, VP Manufacturing, VP Operations, VP Quality, VP Supply Chain, Plant Manager, Director of Plant Operations, Director of Manufacturing Operations, Director of IT, Director of Business Applications, Director of Quality, Director of Production, Director of Supply Chain, CFO, VP Finance, Director of Continuous Improvement, Director of Lean Manufacturing).

Why a Plex Customer List Matters in 2026

Plex Systems is the category-leading cloud MES/ERP for North American automotive Tier 1 and Tier 2 suppliers, with deep IATF 16949 quality compliance, strong shop floor connectivity, and unified MES + ERP + QMS on a single cloud platform. The Rockwell Automation acquisition (2021) strategically positioned Plex as the cloud software complement to Rockwell's plant floor automation. The DemandCaster acquisition (2019) added supply chain planning. The DATTUS acquisition (2021) added direct machine connectivity for real-time production monitoring. The PowerPlex annual customer conference is the dominant automotive Tier supplier manufacturing conference. Modern automotive Tier supplier ERP competitive landscape continues to consolidate around Plex, SAP Automotive, Microsoft Dynamics 365 F&O, Infor CloudSuite Automotive, Epicor CMS, IFS, and QAD AS, with each customer evaluating Plex (cloud-native MES + ERP unified) vs alternatives during ERP refresh cycles.

Plex's automotive Tier supplier depth is exceptional but creates depth gaps where specialist vendors regularly win: modern automotive MES upmarket (Siemens Opcenter MES for Tier 1 OEMs and global, DELMIA Apriso for global automotive OEMs), modern QMS for non-automotive verticals (Greenlight Guru for medical device QMS specifically, Veeva Vault QualityOne for life sciences), modern supply chain planning at growing automotive Tier suppliers (Kinaxis dominant in automotive SCP at large scale, o9 with modern AI-native SCP), modern shop floor IoT with connected workers (Tulip for connected workers and apps, MachineMetrics for cloud-native OEE), modern food traceability for F&B (Trustwell, modern food traceability with deeper recall management), modern aerospace MRO (IFS Aerospace and Trax for aerospace MRO), and modern CMMS for asset-intensive (IBM Maximo, IFS EAM upmarket from Plex Maintenance).

BizzContacts isolates the Plex install base as a separately filterable cohort so vendors can run focused outbound into CIOs, VPs Manufacturing, Plant Managers, and Directors of Quality across the entire Plex customer base.
