LinkMaster provides a means of linking data between OPC servers, thus serving as a universal bridge for OPC systems. LinkMaster acts as both an OPC server and DDE server, allowing it to bridge legacy DDE systems and new OPC-enabled applications.
Programming Knowledge Optional
Simply "Drag and Drop" to create links. Built-in scaling, access manager, and error tracking provide total control of your data flow and applications.
Data Transfer Visibility
Using multiple Link Groups, LinkMaster allows you to control how fast data is transferred from one OPC server to another.
Control Data Transfers
Tailor your data transfers to fit the needs of the application for greater control, reduced network traffic and increased reliability.

Kepware’s LinkMaster provides a means of linking data between OPC DA servers, thus serving as a universal bridge for OPC systems.
LinkMaster can function as a single OPC server that serves data from multiple OPC servers, with the capability to act as both a client and a server.
LInkMaster can help you route data between two PLCs (programmable logic controllers) connected to the same server, using LinkMaster to define the tag data routing.
LinkMaster is transforming the operational efficiency, network traffic, and cost of linking OPC servers.

Explore the features that will change how you think about OPC redundancy. The innovations in RedundancyMaster can work together seamlessly with your current OPC application to give you a more reliable, cost-effective solution.
Built-In Redundancy: A pair of LinkMaster machines can operate in redundant pairs that can shift data in case of a node failure to ensure reliable, ongoing access.
User Management: With the built-in User Manager, gain complete control over what types of functionalities each individual user can access with OPC applications.
Runs as a Windows Service: LinkMaster can run as a Windows service. Service operation is completely user configurable and can changed anytime from standalone to NT service mode.
Link Management: LinkMaster's link management system creates a link database structure that fits the nature of your application.
Data Scaling: Support direct scaling of link item data via LinkMaster, allowing raw data to be converted to engineering units for OPC client applications.
LinkMaster is available in English.
Based on Microsoft's COM technology, OPC servers can share data with remote client applications using DCOM (Distributed COM). DCOM allows you to use a single OPC server to provide data to client applications running both locally and on remote machines. DDE is not without its own means of allowing remote access. All the DDE formats supported by LinkMaster can also be accessed remotely using what is known as NETDDE.
NETDDE allows a remote DDE client application to use the machine name of a remote DDE server when specifying a DDE link. LinkMaster has been designed to allow both methods of remote server access. In terms of OPC connections, LinkMaster will properly configure your DCOM settings to allow remote OPC clients to access and browse LinkMaster. For DDE clients, LinkMaster will automatically start NETDDE services and register all the required DDE shares, allowing remote DDE clients access to device data. Establishing DDE share names can be a time-consuming process for the application, therefore, by default, NETDDE services are not enabled in LinkMaster.
Available LinkMaster application support is as follows:
As of November 15, 2016, LinkMaster V2 is no longer supported. You can continue running a V2 instance but will not receive technical support or software patches. Contact us with any specific questions.
