BridgeMaster OPC Server Linking

BridgeMaster: A powerful OPC bridge

BridgeMaster OPC bridging software enables a range of easy-to-achieve new possibilities that increase your productive capabilities and save you time and money.

With BridgeMaster, you get an OPC bridge between OPC servers that is flexible, reliable and works when other OPC interface software doesn’t. You get maximum OPC connectivity: real-time bi-directional data flow and supervisory control between two or more unlike control systems.

You can easily install, setup and use BridgeMaster yourself. If your systems and their OPC servers are already on a common network, install BridgeMaster on a Windows PC and begin configuring.


The technologies used in BridgeMaster represent a culmination of years of experience developing OPC client and server solutions. Prior to bringing BridgeMaster to market, we tested it vigorously to ensure it will perform well beyond your expectations.

Here are some additional reasons for choosing BridgeMaster as an OPC gateway:

Bridgemaster is easy to install, setup and use with features like configuration auto detect and bulk add. BridgeMaster’s configuration dialog allows easy configuration of the OPC server and node by browsing and selecting an existing OPC server and node.

Bridgemaster is fast. Several schemes in the software optimize performance.

Bridgemaster works. We built it right and test it extensively. Built-in flexibility enables it to adapt to subtle differences in OPC server implementations.

Bridgemaster is reliable. Server redundancy is supported and flexible to your needs. See features or call for details for your application.

Bridgemaster fits your needs and budget. Two license levels, Unlimited and Lite, mean you only pay for the capability you need.

Bridgemaster is supported. It comes with excellent documentation and lifetime responsive technical support.

Prove it yourself. You can download Bridgemaster and try it before you decide to buy it. The demo version is fully functional and can be setup to run up to 45 days with afterwards runs in one-hour resettable periods.

We don’t just develop OPC interfaces; we put our name on them and use them to deliver results for clients.

Ask Us

You’ll find we understand not just the details of how to make OPC work in your application, but also your overall control and information needs and how to achieve them. We have more than 250 professionals in four locations doing this every day.

Need support for your OPC application? Stuck trying to implement an OPC server? Have a question related to control and information system? Ask us. We don’t just support our products, we support you.


Ease of Use

  • Simple configuration with ‘Drag & Drop’ for quickly mapping of tags between servers.
  • Configuration dialog allows easy configuration of the OPC server and node by browsing and selecting an existing OPC server and node for any local or remote server.
  • Simple Tag Map definition dialog allows individual mapping of an ‘A’ side OPC server tag to a ‘B’ side OPC server tag. Tag Map definition includes defining attributes such as OPC Item names, description and data source. Optionally, scaling conversion using conversion tables can be defined to convert raw or discrete values from one system to the other.
  • Easily Import/Export BridgeMaster Tag Map configurations to CSV files, which can be created and/or edited with Microsoft® Excel, Microsoft® Access or any text editor.
  • Supports automatic data conversion with all data types, including arrays of any type (VT_ARRAY), currency (VT_CY), strings (VT_BSTR) and dates (VT_DATE)
  • Runtime ability to add or delete tag maps, change item names, and/or change group update rates, Item Dead Bands, Keep Alive rates, etc.
  • Runtime tag monitoring ability to view and change (read/write) data values in either OPC server from main client window.
  • Error and informational messages displayed in the main window in runtime along with the optional user-configurable specification of maintaining this data in daily log files.
  • Provides shortcuts for pinging servers, starting DCOM configuration utility and external OPC client.


  • User-selectable one-way or bidirectional data flow on a group-by-group basis.
  • Allows selection of writes and reads to be made synchronously (polled) or asynchronously (on data change) on a group-by-group basis as well as selection of whether to transfer VQT or ‘Value-Only’ (when using V3.x OPC servers).
  • User-requested OPC version is selectable on a group-by-group basis, defaulting to “Use Best Available Interface.” Each group provides feedback as to what OPC version is actually being used with the server.
  • Can run as a Windows service for standalone and dedicated data transfer ability (without a user logged in). BridgeMaster control panel application can start and stop the service.
  • Dual redundancy scheme supports redundant OPC server connections implementing user-selectable fail-over mechanisms. It also implements Keep Alive mechanism for redundancy and supports new server status: OPC_STATUS_COMM_FAULT used for redundancy failover.


  • Supports up to 100 system-to-system connectors and unlimited tag maps.
  • Supports and implements OPC DA V3.x improved functionality.
  • Has Bulk Add Items for fast startup configuration.
  • Optimizes data throughput via Bulk Tag Writes (VQT or ‘Value-Only’) during runtime.
  • Allows runtime view of OPC server status and performance statistics.
