04Vertical focus
Industries the vendor names in its own positioning. Absence from this list is not a statement that the system is unsuitable, only that the vendor does not lead with it.

Process manufacturingFormula- or recipe-based production in batches, with lot traceability, yield variance and regulatory documentation as first-order requirements.
05Strengths and watch-outs
Strengths
MES and ERP share one database, so inventory, costing and financials update as work moves through the line rather than through a batch interface.[1]
The quality module supports IATF 16949, ISO 9001, AS9100 and FDA requirements with control plans, FMEA, SPC, non-conformance and CAPA, supplier quality and document control.[1]
Multi-tenant SaaS accessed through a web browser; the company has delivered its software this way since Plexus Online launched in 2001.[3]
Owned by Rockwell Automation, whose software directory lists Plex ERP alongside Plex MES, Plex Quality Management, Plex Asset Performance Management, Production Monitoring and FactoryTalk.[2]
Human resources covers employee records, time and attendance, labour tracking, skills matrices, safety incidents and benefits, feeding labour cost into job costing.[1]
Supports more than 25 interface languages, including Chinese, German, Japanese, Korean, Polish, Portuguese and Spanish.[1]
Watch-outs
Cloud only; there is no on-premise deployment option.[1]
CRM is described as basic; Salesforce, SugarCRM and Microsoft Dynamics CRM are the named integration options.[1]
Pricing is a per-user subscription quoted by the vendor rather than a published list; shop-floor and data-collection users are priced differently from full ERP users.[1]
Built for manufacturers; the source flags limited fit for services businesses and for very small shops.[1]
Ownership has changed several times: Apax Partners (2006), Francisco Partners (2012), then Rockwell Automation (2021).[3]
06Consider when
Consider Plex when you run automotive, aerospace, food and beverage or medical device plants where shop-floor traceability and quality compliance drive the selection.[1]
Consider Plex when you already run Rockwell Automation plant software and want MES, quality and ERP from the same owner.[2]
Systems with a comparable size fit and cost band, which is why they appear on the same shortlists. Each link opens a head-to-head built from both records. They are the pairings a buyer is likely to shortlist, not a limit on what can be compared: any two systems in the dataset can be laid side by side, including combinations we never pair.
Yes. Plex Manufacturing Cloud is delivered as multi-tenant SaaS accessed through a browser, and there is no on-premise option.[1]
Who owns Plex?
Rockwell Automation, which acquired Plex Systems in June 2021 for 2.22 billion dollars in cash. Plex Systems was formed in Troy, Michigan in 1995.[3]
How is Plex priced?
As a per-user subscription quoted by the vendor; there is no published list price. The number depends on user count, which modules you license (ERP, MES, QMS, planning, analytics) and implementation scope.[1]
Which industries use Plex?
Discrete and process manufacturers, with concentrations in automotive, aerospace and defence, food and beverage, industrial manufacturing and medical devices.[1]
Does Plex include HR and payroll?
It includes a human resources module covering employee records, time and attendance, labour tracking, skills matrices and benefits, and the source says payroll runs on that integrated labour data.[1]
What does Plex QMS cover?
Control plans, FMEA, SPC, non-conformance and corrective action, supplier quality and document control, supporting IATF 16949, ISO 9001, AS9100 and FDA requirements from the same database as the ERP and MES.[1]
Does Plex have ecommerce or field service?
No. The source lists no ecommerce or field service modules.[1]
