Drag and drop support for adding OPC data items (tags)

Supports dynamically-created tags

Provides flexible triggering

It is also possible to extract data from Databases, using the ODBC Driver.

IoT & Web-Server connectivity

It is now possible to link real-time production data, from KEPServerEX, with business-level IT systems using this advanced plug-in.

The IoT Gateway seamlessly streams real-time industrial data directly into

site-based web-servers

Enterprise-level device clouds

Internet-hosted IoT Cloud analytics platforms

….using the standard of RESTful web services.

The IoT Gateway connects Operations with IT, allowing business-level users, across the Enterprise, to monitor, analyse, and visualize data in real-time.

improved enterprise-wide decision-making, based upon real-time data

real-time visibility of the same production data, across multiple business levels

more efficient production and capacity planning

quicker root-cause, problem analysis & anomaly detection

coherent data-security across all levels of the Enterprise

Advanced Plug-ins

Media Level Redundancy for KEPServerEX enables users to quickly and easily establish redundancy, ensuring reliable communications with critical assets

LinkMaster is a universal data-bridge, for both OPC servers and clients.

Typical uses include aggregating data into one location and bridging data-values between OPC Servers


Advanced Tag Option for KEPServerEX

The Advanced Tag Option for KEPServerEX offers a convenient, cost effective, and straightforward way to generate 'secondary' or derived data, from existing OPC data.

This is typically undertaken to aggregate existing data into extremely valuable, information-based data, which is more suitable for high level archive and analysis.


KepServerEX Alarms & Events plug-in

Kepware's Alarms and Events plug-in for KEPServerEX can help reduce costs and improve performance.

OPC AE clients can receive and monitor process alarms, operator actions, informational messages and tracking/auditing messages directly from the KEPServerEX's Alarms and Events Plug-in.


Kepware OPC DataLogger

The DataLogger is an easy-to-configure application that logs data from an OPC server to any ODBC-compliant database.

DataLogger's tight integration with KEPServerEX provides substantial, unique benefits such as simple installation, high-efficiency performance, and easy browsing of tags in the OPC browse space.



RedundancyMaster increases the reliability and availability of OPC data by allowing multiple OPC Servers to be configured into redundant pairs.

Each redundant pair seamlessly appears as a single OPC Server to any OPC Client application.

RedundancyMaster can be added to any existing server/client application without any reconfiguration of the application, keeping your processes going with no downtime.


KepServerEX OPC UA Connectivity Suite & Tunneler

The OPC UA Client Driver, together with the free OPC UA Server for KEPServerEX, provides an ideal solution for securely tunneling OPC data across a local area network, a wide-area network, or even across the Internet.

 The OPC UA Client Driver provides a communications tunnel between two or more computers, allowing data to be transferred securely and reliably. This eliminates reliance on Microsoft COM and DCOM technology, and provides higher performance and deterministic failure modes.
