This report provides details regarding the availability, legal acquisition, and status of KEPServerEX V4.0. 1. Availability and Current Status

KEPServerEX Version 4.0 is a legacy industrial connectivity platform.

End of Life: This version reached its end-of-life status on November 15, 2016. It is no longer supported by the manufacturer, meaning it receives no security patches, technical support, or software updates.

Modern Successors: The software has been superseded by Kepware Server (formerly KEPServerEX V6 and V7), which is the current flagship product. 2. Official "Free" Access: The Demo Mode

There is no perpetual "free" full version of KEPServerEX. Instead, the official way to use the software without an upfront cost is through a Demo License.

Two-Hour Runtime: The demo version provides full functionality but only runs for two hours at a time. After this period, the server must be restarted to continue operation.

Repeating the Trial: Users can repeat this demo period as often as needed by stopping and starting the application.

Unlimited Counts: During the demo period, channel, device, and tag counts are typically unlimited. 3. Downloading V4.0

Finding a "free" download for KEPServerEX V4.0 is difficult because it is a legacy software product that has been officially retired and replaced by newer versions

(like V6.x). Kepware generally does not offer public downloads for version 4.0 anymore, as it is no longer supported.

However, if you have a legacy system that requires this specific version, here is a comprehensive guide on how to approach the installation, licensing, and usage of KEPServerEX V4.0. 1. Sourcing the Software

Since Version 4.0 is legacy software, you won't find it on the standard Kepware download page Check Original Media

: Most users still running V4.0 rely on the original installation CD or a backed-up ISO file from their initial purchase. Contact Support : If you have a valid license ID, you can contact Kepware Technical Support

. They may provide a "Legacy Download" link if you can prove ownership. Avoid Third-Party Sites

: Be extremely cautious of sites claiming to offer "KEPServerEX V4.0 Free Download" or "Cracks." These files are often bundled with malware or are unstable, which can be catastrophic for industrial control systems. 2. System Requirements (Legacy)

Version 4.0 was designed for older operating systems. Attempting to run it on Windows 10 or 11 often results in driver conflicts or registry errors. Operating System : Windows 2000, Windows XP, or Windows Server 2003. Compatibility Mode

: If you must use Windows 7, you likely need to run the installer in "Compatibility Mode for Windows XP (Service Pack 3)" and as an Administrator. 3. Installation Steps If you have obtained the setup file (usually KEPServerEX.exe ), follow these steps: Preparation

: Disable any firewalls or antivirus software temporarily, as they can block the installation of the local runtime service. Run Installer : Right-click the setup file and select Run as Administrator Feature Selection

: You will be asked which drivers to install (e.g., Allen-Bradley, Modbus, Siemens). Only select the drivers you need to minimize system overhead.

: Once installed, the "KEPServerEX Runtime" will appear in your system tray (bottom right corner). 4. Configuration Guide

The V4.0 interface is different from the modern V6 version. It uses a "Channel > Device > Tag" hierarchy. Step A: Create a Channel : Right-click on the "Project" folder and select New Channel . Choose the communication protocol (e.g., Modbus TCP/IP). Step B: Add a Device : Right-click your new Channel and select New Device . Enter the IP address or station ID of your PLC/Hardware. Step C: Define Tags

: Under the Device, add Tags. You must specify the address (e.g.,

for a Modbus holding register) and the data type (Word, Boolean, Float). 5. Licensing and Trial Mode Trial Period

: When installed without a license, KEPServerEX V4.0 typically runs in Timed Mode . This allows full functionality for

at a time. After 2 hours, the runtime stops, and you must restart the service to continue testing. Legacy Licensing

: V4.0 used a different licensing utility than the modern "License Utility." It often required a "Hardware Key" (USB Dongle) or a manual "Emergency Activation" code provided by Kepware. 6. Why You Should Upgrade

If you are starting a new project, using V4.0 is highly discouraged for several reasons:

: V4.0 does not have modern encryption or security patches, making it a major vulnerability on a network. Operating System Support

: It will not run natively on modern 64-bit Windows Server environments. Driver Efficiency

: Newer versions (V6.15+) have significantly better performance and support for modern PLC firmware. Do you have a specific PLC model you are trying to connect to using this version?

While KEPServerEX V4.0 is a legacy version (first released around 2004), it remains relevant for maintaining older industrial systems. Official support from PTC Kepware has largely transitioned to newer versions, but historical files and demo modes are still accessible for legacy maintenance. Download Options

Official Demo: You can download the latest version (v6+) as a free demo from the official PTC Kepware site. The demo is fully functional but limited to 2-hour sessions before the service needs to be restarted.

Legacy Version 4.x: For specific legacy requirements, third-party distributors like Lamonde Automation host archives of older installers, such as v4.500.465. Key Features of V4.0

KEPServerEX V4.0 served as a foundational 32-bit Windows application for industrial data bridging: We strongly advise against downloading V4

Protocol Support: Offered a wide range of industrial drivers (PLC, RTU, etc.) to convert various protocols into a standardized OPC format.

Modem Connectivity: Supported dial-up modem tags at the channel level for connecting to remote devices.

Client/Server Architecture: Enabled data sharing between hardware and client applications like HMI, SCADA, or ERP systems. Deployment Considerations Index of /downloads/kepserverex/4/4.500.465 - Lamonde
