OPC DA – BACnet IP Gateway (PG-103-125) Solutions is a powerful, excellent, fully flexible, and productive Building & Industrial Automation gateway that allows integrators to easily connect devices to networks in commercial buildings and industrial facilities.

BACnet IP and OPC DA (client only) protocols are supported by the PG-103-125 gateway.


This gateway may be set up to do the following:

OPC DA Client and BACnet IP Client : This gateway will connect to a third-party OPC DA server and read or write tags. It will, however, be a BACnet client that can receive and write data from a BACnet server.

When you have BACnet IP -based server devices and require a way to read and write values to your OPC server, this mode comes in handy. Alternatively, you may wish to read OPC DA tags on a regular basis and write the values to a BACnet server device.


OPC DA Client and BACnet IP Server: The most frequent form of operation is using an OPC DA client and a BACnet IP server. In this mode, the gateway is set to read OPC DA tags and broadcast them as a server on BACnet IP .

This is most likely the most popular operating mode. In this mode, the gateway is set to read OPC DA tags and broadcast them as a server on BACnet IP .

As a result, a third-party building automation/management system (BAS/BMS) may now read all of this Modbus data (and hence have access to the OPC DA data via the gateway). OPC DA tags may also be written from the BACnet side. As a result, the BAS/BMS system can use the gateway to set values on the OPC DA server.

With its robust set of features, the Gateway has benefited system integrators all around the world. The gateway also runs the same protocol conversion software on a productive and cost-effective platform, backed by the same experience, engineering skill, and technically proven support that integrators have come to expect from this Gateway.





  • In the standard version, you may interface up to 1000 points (upgrades to higher points can be purchased).
  • DIN rail attachment.
  • BACnet COV support for fast data communication while reducing the traffic over a BACnet network


Application Scenarios:

  • This gateway is frequently used to connect OPC DA-enabled lift/elevator/escalator systems to a BMS/BAS system running on BACnet IP .
  • An OPC DA interface is available on some fire alarm systems. You may also use this gateway to monitor your fire system from your BACnet-based BMS/BAS.
