Siemens (S7-200/300/400/1200/1500), Modbus (Serial & Ethernet), Mitsubishi, Omron, Schneider Electric, GE/Emerson, Fanuc, and various CNC/Robotic protocols.
In terms of the "engine" under the hood, both provide the same industry-leading reliability. The decision isn't about performance—it's about who you want to call when you need support and how you prefer to manage your software budget.
This is a specialized, rebranded version of KEPServerEX. It is specifically developed by Kepware for Rockwell Automation . It is sold, bundled, and supported exclusively through Rockwell Automation and its distributor network (Allen-Bradley). 2. Architecture and Driver Availability
KepserverEX is the right choice for the . Do not assume you need Enterprise just because you have a critical process. kepserver enterprise vs kepserverex
Your facility is standardizing completely on Rockwell Automation software (FactoryTalk), you want to leverage your existing Rockwell TechConnect support contract, and your only goal is to pull a few third-party PLC tags into a FactoryTalk HMI or Historian.
Result: Manual or "bumpless" failover is not guaranteed.
To truly understand the differences, it’s vital to examine the underlying technology that makes these platforms tick. This is a specialized, rebranded version of KEPServerEX
If you are currently evaluating these two platforms for an upcoming deployment, I can help you map out the exact driver compatibility and licensing path. Let me know: What you need to connect to. What SCADA, MES, or Cloud platforms will receive the data.
Security is a key consideration that also helps differentiate these platforms.
is distributed, high-availability data streaming platform . It is not a different server, but rather a constellation of KepserverEX instances managed as a single logical device. GE Digital iFIX
is the workhorse for 95% of industrial automation projects. It’s stable, well-documented, and cost-effective. Most users will never outgrow it.
KEPServerEX is built on an open, multi-vendor philosophy. It does not favor any specific SCADA, MES, or ERP vendor. It exposes data through standard, open interfaces such as OPC UA, OPC DA, MQTT, REST, and native database connections. Whether you are running Ignition by Inductive Automation, GE Digital iFIX, Wonderware/AVEVA System Platform, or a custom-built cloud telemetry application, KEPServerEX treats them all equally. KEPServer Enterprise: The Rockwell Ecosystem Anchor
Works with almost any third-party software (Ignition, Wonderware, GE Digital, etc.).
If you are starting a new project today, is the recommended starting point due to its modern architecture, centralized management, and future-ready feature set. KEPServer Enterprise remains the correct choice only for customers deeply invested in the Rockwell Automation ecosystem who need to integrate third-party devices. The classic KEPServerEX is now a legacy product being superseded by Kepware Server.
Features a curated, restricted subset of drivers compared to EX.
