KEPServerEX v5 OPC and Communications Server Features

KEPServerEX v5 is the next generation of Kepware communications technology and represents over 10 man year's worth of development, delivering both architectural and feature enhancements. KEPServerEX v5 is
the most advanced communication technology and OPC Server on the market and will remain the foundation for future Kepware development. As a result of our new licensing utility, Kepware is providing new vertical driver suites including Building Automation, Oil and Gas, and Water and Waste Water to name a few.

KEPServerEX v5 has been re-designed from the ground up to take advantage of new technology, and is positioned to move onto new automation platforms while delivering legacy compatibility.


OPC Connection Security

The Secure by Default feature enables users to select whether or not the server should respect the DCOM security settings as they appear in the DCOM Configuration Utility. When this setting is enabled, users can select the authentication, launch and access security requirements through the DCOM Configuration Utility. This allows users to specify the level of security they want to implement and also restrict access for certain users and/or applications.

When this setting is disabled, the server will override the DCOM settings set for the application and will not perform any authentication on the calls received from client applications. It will impersonate the security of the client when performing any actions on behalf of the client application.

Process Mode

KEPServerEX runtime Process features are used to specify how the servers runtime process mode will operate and utilize PC resources. It is used to specify whether the server will be running as System Service or Interactive.

KEPServerEX also allows you to set its own process priority giving the server priority access to resources.

Processor Affinity

This parameter allows the user to specify which CPUs the server can be executed on when it is run on PCs containing more than one.

Host Name Resolution

KEPServerEX allows for host name resolution which is an alias assigned to identify a TCP/IP host or its interfaces. Host names are used in all TCP/IP environments and user can specify host name instead of an IP address when using KEPServerEX v5.

OPC UA (Unified Architecture)

KEPServerEX supports OPC UA Client Connections and the OPC DA data set.

OPC AE (Events)

KEPServerEX exposes event log data (Events) to OPC AE Client applications. The Event server works in runtime and service modes supporting 3 Event categories (Information, Warning, Error). KEPServerEX also supports AE client filtering by event type, severity, and category and is OPC Compliant.

ProgID (Program Identification) Redirect

This feature allows users to map third-party servers' OPC registration to KEPServerEX, providing users with a quick solution mapping and reconfiguring OPC Client projects.

Scan Floor Rate

Ability to manage device and application read requests. Overrides client application read requests.

Server Administration Properties

The User Management system of the server controls what actions a user can take within a server project. The User Properties dialog is used to configure the name, password and privileges available for each account.

Multiple Tag Generation Utility

Quickly and dynamically construct multiple tags using the KEPServerEX driver nomenclature. It will allow for a wide variety of address formats such as ranges utilizing hex, octal, decimal, and binary number systems. It will also include the ability to increment the user selected data-type to avoid data overlap.
