KEPServerEX: One Data Source for your Industrial Automations

The KEPServerEX connectivity platform offers simultaneous accessibility to client applications through an ever-growing list of supported industry standards, proprietary technologies, and native client interfaces including:

• DDE Native Interface
• FastDDE/SuiteLink Native Client Interface:
• iFIX Native Client Interface
• MQTT
• ODBC
• OPC Alarms and Events (AE)
• OPC Data Access (DA)
• OPC Historical Data Access (HDA)
• OPC Unified Architecture (UA)
• REST
• SNMP
• Splunk
• Thin-Client Terminal Server

With the Configuration API, remotely apply programmatic changes to KEPServerEX configuration via third-party client applications that utilize a REST-based API—such as web clients, SCADA software that supports HTTP, and Internet of Things (IoT) platforms. With minimal programming, remotely change any project and use templates to standardize creation and naming among different device types. All changes take effect immediately. The Configuration API is helpful for users with large, constantly changing projects.

The Configuration API offers the features needed to bundle actions into a single transaction, programmatically complete key tasks, and easily optimize KEPServerEX performance such as:

• Programmatic Object Management: Apply programmatic changes to Create, Read, Update, and Delete (CRUD) objects—such as channels, devices, and tags—in the server
• Simplify Project Creation: Programmatically build project files or load full projects from a mapped file directory
• Batch Tasks: Create an object with a child hierarchy in a single transaction or multiple objects in a single transaction
• Programmatic Access: Programmatically access the Event Log, configure drivers, and oversee users and permissions
• Configuration Security: Protect the project configuration by restricting modifications by role

Top-tier Kepware drivers and core components of KEPServerEX are localized into Japanese, German and Simplified Chinese. These localizations give native Japanese, German and Chinese speaking-users more accessibility and confidence when configuring, monitoring and troubleshooting KEPServerEX.

Language selection is easy to access, so users can change their preferred language at any time. Japanese, German and Simplified Chinese localizations are installed by default where available.

• Drivers: Drivers have been localized for products such as Allen-Bradley, MODBUS, Mitsubishi, OMRON, and Siemens.
• Interface: Non-driver items that have been localized include the Administrative Panel, Configuration Utility, Connection Sharing, and more. Get the full list below.
• Support: Help Documentation, Event Logs, and Installation support have been localized. Get the full list of non-driver localizations below.

Media Level Redundancy establishes a redundant connection to a single device or a pairing of two devices.

Media Level Redundancy for KEPServerEX enables users to quickly and easily establish redundancy, ensuring reliable communications with critical assets. In the event of a failure, Media Level Redundancy allows the duplicate device or redundant system to take over without interrupting service—preventing data loss, maximizing uptime and increasing the availability of industrial data. Redundancy supported includes:

• Communications Path Redundancy: Communications Path Redundancy provides multiple network paths to communicate to a critical device.
• Device Pairs Redundancy: Device Pair Redundancy configures two devices as a redundant unit.
• Dual Redundancy Options: Users can combine the redundancy types to eliminate the single point of failure with either option.

Kepware's OPC tunneling solution uses a client/server architecture for secure and reliable real-time data tunneling through firewalls and across the internet, WAN, or LAN. It allows for easy remote communications between devices, data sources, and applications by eliminating the reliance on Microsoft COM and DCOM technology.

Key OPC tunneling benefits include:

• Easy Setup: KEPServerEX OPC Tunneling offers easier setup and configuration than DCOM
• Firewall Friendly: Easily tunnel through firewalls to share the data needed between OPCs
• Widely Compatible: The KEPServerEX robust portfolio of client interfaces and devices
• Secure: Secure and reliable data transfer using 256-bit AES message signing and encryption
• Scalable: Multi-threaded architecture and non-blocking asynchronous messaging for performance, scalability, and reliability

Streamline your OPC data and project security. KEPServerEX Security Policies allow administrators to assign security access permissions on individual objects (such as channels, devices, and tags) based on user roles. It is used in conjunction with the server's User Manager, which enables management of user groups, users, and default security settings. Security Policies are included with KEPServerEX, no additional purchases required. The tools allow you to:

• Allow and deny Dynamic Tag addressing
• Organize security policies by user groups
• Support for the following user group access categories:
• Dynamic Addressing
• I/O Tags
• System Tags
• Internal Tags
• Browsing
• Support for the following user group permission types:
• Read
• Write
• Browse
• View and locate prior changes through the advanced plug-in interface’s font styling hierarchy and color scheme
• Copy permissions for the current access category to/from a user group
• Move permissions for the current access category to/from a user group

With minimal configuration required, the ThingWorx Native Interface feeds industrial data—provided by KEPServerEX—directly into ThingWorx. All the data in KEPServerEX is immediately available to browse within the ThingWorx Composer, so users can easily manage tags for all their connected Things, visualize and analyze data, kick off events in other systems, and more.

The ThingWorx Native Interface takes less than ten minutes to implement—enabling unparalleled time-to-value for IoT applications across diverse industries.

Key benefits of the ThingWorx Native Interface for KEPServerEX include:

• Remote Project Loading: Users can easily deploy KEPServerEX projects remotely—while editing network settings, configuring and managing KEPServerEX instances from a single ThingWorx interface.


• Store and Forward: Users can seamlessly transfer data between KEPServerEX and ThingWorx—even in the event of a communication loss or unstable connection.


• Proxy Support: Users can connect KEPServerEX to ThingWorx via a proxy in order to implement network and security best practices when connecting to the cloud or via a wide area network (WAN).

There is no specific line item or cost associated with KEPServerEX when making a purchase. KEPServerEX is sold “à la carte” based on the different drivers and advanced plug-ins needed to establish the desired communications–these are what determine the price.

The majority of our products are not sold with a limit. There are, however, a handful of products that are sold on a tiered basis as it relates to device or tag count. Please feel free to contact us if you need help identifying those products.

Kepware products are currently licensed on a permanent basis. Once you have acquired the license with the initial product purchase, you do not have to purchase it again.

While a Support and Maintenance Agreement is mandatory for the first year, extending it is strongly encouraged as it provides you with on-going access to our Technical Support team and upgrades to the latest version of the KEPServerEX connectivity platform (generally released two times a year).

KEPServerEX products are licensed on a per server basis; each server would need its own license. As an example, if you had two servers that needed to utilize our Allen-Bradley Suite, you would need to purchase two Allen-Bradley Suite product licenses—one for each instance of KEPServerEX.

Yes—Whether you’re an existing PTC Kepware customer or if you’re ready to start your connectivity journey, a subscription plan is available that will give you access to the following among its many perks:

• Seamless upgrades along with maintenance and security updates
• A single type of license environment to manage, minimizing IT and administrative burden
• Bundled support and maintenance so you never have to worry about your product’s eligibility
• Long-term pricing benefits for your entire installation—including licensing that can be scaled up or down as needed
