KEPServer Enterprise KEPServerEX share the same core technology developed by Kepware, they are packaged and sold differently to serve distinct industrial ecosystems. Essentially, KEPServer Enterprise is a version of KEPServerEX that has been rebranded and customized Rockwell Automation environments. Core Differences Vendor and Support KEPServerEX is the flagship product sold and supported directly by PTC (formerly Kepware)

. It is vendor-neutral and designed to work across any industrial automation platform. KEPServer Enterprise is sold and supported by Rockwell Automation . It is specifically tailored for use with the FactoryTalk Integration with FactoryTalk KEPServer Enterprise is often bundled with Rockwell software like FactoryTalk View Studio

. It includes specific features to simplify communication between non-Rockwell devices and FactoryTalk systems, such as automated tag importing. KEPServerEX requires manual configuration as a standard OPC UA server kepserver enterprise vs kepserverex

when connecting to FactoryTalk, though it offers more flexibility for complex, multi-vendor architectures. Driver Availability KEPServerEX

offers the full library of over 150 drivers and advanced plugins (like the IoT Gateway or Advanced Tags) which can be licensed individually. KEPServer Enterprise typically comes as a pre-packaged suite

of the most common drivers used in the Rockwell ecosystem (e.g., Modbus, Siemens, Mitsubishi) to facilitate "enterprise-wide" connectivity. KEPServerEX licenses are managed through the My Kepware portal KEPServer Enterprise licenses are integrated into the Rockwell Automation licensing system

, allowing users to manage it alongside their other Rockwell software. Which One Should You Use? Recommended Version Primarily using Rockwell/FactoryTalk and want integrated support. KEPServer Enterprise Building a vendor-neutral IIoT platform or using various SCADA systems. KEPServerEX specialized drivers or the latest cutting-edge features from PTC. KEPServerEX Want to purchase and manage all automation software through one Rockwell contract KEPServer Enterprise : PTC recently announced that KEPServerEX is evolving into Kepware Server unified platform

designed for better scalability and centralized management across large-scale enterprises. specific drivers included in the Rockwell Enterprise package or how to from one version to the other? Part 5: When to Choose Kepserver Enterprise Enterprise

Here’s a technical review comparing Kepserver Enterprise (now often referred to as KepserverEX Enterprise Edition or part of the Industrial Connectivity Suite) and KepserverEX (the standard version).

Part 5: When to Choose Kepserver Enterprise

Enterprise exists exclusively to solve the reliability and operational continuity problem. If any of the following statements are true, you need Enterprise.

2. You have a 24/7/365 operation (pharma, refining, power)

Unplanned downtime in a refinery costs $1M+ per hour. In a data center, it’s even higher. Enterprise provides redundant power supplies, redundant NICs, and redundant servers—all managed through a single configuration.

5. You are acting as a "supervisory" aggregator for a plant floor

Some factories use Kepware to aggregate data from 10+ sub-networks (each with its own PLC). If that aggregator goes down, all dashboards, MES, and historians go blank. Enterprise ensures that aggregator is redundant.

KepserverEX Licensing

• Base Server License: Includes 100 tags, 1 driver (e.g., Modbus).
• Tag Expansion Packs: Sold in increments (500, 2k, 10k, 25k, 50k, 100k).
• Drivers: Each driver family (Allen-Bradley Suite, Siemens Suite, IEC 61850) is an additional cost.
• Plug-ins: MQTT Client, REST Server, Data Logger, SNMP Agent – each extra.
• Subscription vs Perpetual: Subscription includes support; perpetual requires a separate annual maintenance (20% of license cost).

Part 1: The Core Definitions

Part 10: Decision Flowchart – Which One Is for You?

Ask yourself these five questions:

1. Is your plant a 24/7 operation?

   • No → KepserverEX
   • Yes → Proceed to Q2

2. Can you tolerate 10 minutes of downtime in a year?

   • Yes → KepserverEX (with manual backup)
   • No → Proceed to Q3

3. Do you have regulated alarms (FDA/NERC) that require acknowledgment persistence?

   • Yes → Kepserver Enterprise
   • No → Proceed to Q4

4. Do you have more than 75,000 tags on a single instance?

   • No → KepserverEX (but split into zones)
   • Yes → Kepserver Enterprise (or distribute across multiple EX instances)

5. Is your IT team comfortable managing SQL Server, Windows Failover Clustering, and dual-server networking? KepserverEX Licensing

   • No → Stick with EX and accept the risk. Enterprise adds significant IT complexity.
   • Yes → Enterprise is justified.
