The LinkMaster Universal OPC Data Bridge software is designed to provide an automated and bi-directional means of data transfer between different control system hardware or between enterprise systems supporting OPC and shop floor systems supporting OPC. Linkmaster is a powerful, time and money saving integration tool that requires no programming expertise to use.
The LinkMaster Universal OPC Data Bridge software is used to move data in an automatic and bi-directional fashion between any OPC Data Access 1.0 or 2.0 servers.

Applications include moving data from HMI to DCS systems and back, from one PLC brand to another, from one HMI to another, between enterprise systems and the shop floor and more. Any application where you have more than one system and you need to get data from one to the other and there is no direct link would be worth considering LinkMaster for.

LinkMaster is a fast and robust Windows application that requires no programming knowledge, simply "Drag and Drop" to create your links. Built-in scaling, user-access manager, error tracking, and write optimization capabilities, provide total control of your data flow and application access.

Supports COM and DCOM

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 of 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 of these 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 of 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.

Runs as NT Service

LinkMaster supports running as a service under Windows NT/2000. Service operation is completely user configurable from the Tools|Options menu, and can be changed at any time allowing you to move from normal, stand alone program operation, to NT service mode. Running as a NT service is crucial for many applications where LinkMaster is providing data to OPC clients via DCOM. For these applications, loss of a DCOM connection can not be tolerated. Normally, an OPC server that only supports stand alone program operation is forced to shut down when the host machine experiences a user log in or log out. While running as a service, LinkMaster can continue to supply OPC data across user log in sessions and can be configured to interact with the desktop, allowing you to make changes to your LinkMaster project. It can also be configured to have a non-visible presence while running.

Data Scaling

LinkMaster supports direct scaling of link item data. Scaling allows raw data to be converted to engineering units for OPC client applications. LinkMaster provides a number of unique scaling features, such as Linear and Square Root formula scaling. You can also specify the range of the raw data input and the engineering range of the scaled value. In some cases, the raw data input received may exceed the range set for the raw data. If this occurs, the engineering value can be forced outside of the range you desire. To prevent this, LinkMaster allows you to clamp the scaled value to the engineering ranges. In most cases, it is always assumed that a scaled value results in a floating point number. LinkMaster doesn´t make this assumption and allows you to select the scaled engineering value to be any valid OPC data type. This means you can scale a 16-bit integer value to a 32-bit integer value.

Link Item Management

LinkMaster´s link management system allows you to create a Link database structure that fits the nature of your application. Multiple Link groups can be added and defined to segregate your Link items into meaningful groups. Drag and drop editing makes adding a large number of tags easy. Unique Link Management features allow new links to be created on the fly using convenient "Drag and Drop" and "Tag Browsing" methods.

User Management

In certain situations, managing what your users can and cannot do in your OPC application can be a necessity. LinkMaster includes a built in User Manager that allows complete control over what types of functionality each individual user can access. The default administrator account allows you to add multiple users, each with their own set of rights for LinkMaster access. Any user log in/log out is recorded in LinkMaster´s event logging system- the EventViewer. By default, all operations are available at all times until you decide to set privileges.

Event Viewer

Included with the LinkMaster package is a stand alone event monitoring application called the EventViewer. The EventViewer is a 32-bit Windows application that monitors and displays events occurring on any running LinkMaster application, either remotely or locally, allowing multiple LinkMaster systems to be monitored concurrently.
