KepServer Enterprise is a more comprehensive solution developed by Kepware, designed to address the needs of large-scale industrial organizations. This product builds upon the features of KepServerEX, offering additional capabilities and scalability. Key features of KepServer Enterprise include:
Focuses heavily on Allen-Bradley/Rockwell and common 3rd party protocols
A forward-looking consideration is the evolution of PTC’s product line. As PTC unifies its offerings into Kepware Server and Kepware Edge, the future of KEPServerEX as a brand is being phased out in favor of this more capable, unified platform.
Latency, CPU utilization, and memory footprints remain identical because they share the same core executable engine. 4. Key Differences: KEPServer Enterprise vs. KEPServerEX
| Feature | KEPServerEX (Standard) | KEPServer Enterprise (Rockwell Edition) | | :--- | :--- | :--- | | | Uses PTC's licensing system and tools | Exclusively uses FactoryTalk Activation | | Primary Support Channel | PTC and its network of distributors | Rockwell Automation and its ecosystem | | Sales & Distribution | Sold directly by PTC and a global network of partners | Sold only with specific Rockwell Automation applications (e.g., FactoryTalk View, PlantPAx) | | Integration Focus | Broad, general-purpose industrial connectivity | Deep, optimized integration within Rockwell Automation environments | | Use Case | Heterogeneous environments with diverse device brands | Predominantly Allen‑Bradley systems requiring non‑Rockwell device connectivity |
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:
| Feature | KepserverEX | Kepserver Enterprise | | :--- | :--- | :--- | | | Single node | Redundant pair (Active/Standby) | | Failover Type | Cold / Manual (bumpy) | Hot / Automatic (bumpless) | | Configuration Storage | Local XML file | Central SQL Database | | Max Tags (Typical) | 50k – 100k | 200k+ (spread across two nodes) | | Driver Suite | All available (AB, Siemens, Modbus, MQTT, etc.) | Same drivers + Redundancy driver | | Alarm Synchronization | No | Yes (ACK states, disabled states persist) | | Historical Data Cache | Local only (Kepware's Data Logger) | Shared via SQL or Enterprise logging | | Licensing | Per installation (node-locked or floating) | Per pair (includes both nodes) + SQL license | | Cloud/IIoT Ready | Yes (Native MQTT, REST, Sparkplug) | Yes, but now with redundancy for cloud gateways | | Management Tools | Local Configuration API / Web Admin (optional) | Enterprise Console (centralized deploy & monitor) | | Typical Uptime | 99.9% (requires manual intervention) | 99.999% (automatic recovery) | | Price Indicator | $2k – $15k | $15k – $50k+ |
