Provides a curated subset of drivers. It focuses primarily on the most common third-party protocols needed by Rockwell customers, such as Siemens, Modbus, and various legacy fieldbuses. It deliberately excludes certain drivers that compete directly with Rockwell’s native communication software, FactoryTalk Linx. Software Integration and Ecosystems
KEPServerEX is the flagship connectivity platform developed directly by Kepware (a PTC company). It serves as a single server interface to connect, manage, monitor, and control diverse automation devices and software applications. Core Architecture
KEPServer Enterprise and KEPServerEX share core technology but differ in distribution, with Enterprise bundled for Rockwell FactoryTalk, while EX serves as a standalone solution with full driver support. While Enterprise is integrated into Rockwell’s ecosystem for 3rd-party drivers, EX acts as a universal connectivity platform for various SCADA/IoT applications.

What are you currently using or planning to deploy? kepserver enterprise vs kepserverex
Production facilities heavily standardized on the Rockwell Automation ecosystem (Allen-Bradley PLCs, FactoryTalk software). 3. Key Differences: Feature Comparison Distribution and Support
It uses FactoryTalk Activation , meaning if you already manage your PLC and HMI licenses through Rockwell, you don't need a separate licensing tool for your communication server.
Summary
At first glance, they look identical. Both use the same user interface (the renowned Kepware Configuration API). Both support the vast library of plug-in "drivers" (ranging from Allen-Bradley to Siemens to Modbus). Yet, they serve fundamentally different markets and architectural needs.
Place the SQL database on a separate, highly available cluster.
Ultimately, the choice between KEPServerEX and KEPServer Enterprise does not come down to performance, as both utilize the same robust communications engine. Instead, the decision hinges entirely on your . If your plant relies on FactoryTalk, KEPServer Enterprise streamlines licensing and support. If your plant is vendor-agnostic or uses a different SCADA platform, KEPServerEX offers the agility, direct support, and precise licensing flexibility you need. Provides a curated subset of drivers
Checklist for procurement and architecture
You only need one or two specific drivers and do not want to pay for a bundled suite of drivers you will never deploy. Choose KEPServer Enterprise if:
While based on KEPServerEX, it often prioritizes Allen-Bradley drivers, though it still supports a wide range of third-party protocols. GE Digital (iFIX)
uses FactoryTalk Activation. Support is often handled through your Rockwell Automation distributor. 2. The "Ecosystem" Factor
Your SCADA/HMI layer is built on Ignition, Wonderware (AVEVA), GE Digital (iFIX), or proprietary cloud applications.
