HowTo: Add and Connect to a COM Server

This HowTo describes how to add and connect to a local COM DA3 Server from UaGateway using local discovery.

To add and connect to a COM Server with the UaGateway, start the Configuration Tool (by right clicking on the Notification Area Icon).

Locate the Devices Address Space window on the left side of the Configuration Tool and select "OPC COM DA Servers".

In the Main Window, a list of all configured COM Servers will appear. Click on "Add Server..." to add a new COM Server to the UaGateway.

Add COM Server 1

A new window will show up where the information which is necessary to connect to the COM Server has to be entered. To add a local COM Server, expand the tree at "Local" and select the desired COM DA Server (here: Kepware’s KEPServerEx).

Warning

Only connections to local COM servers are supported see No Remote DCOM Connections.

After pressing the button "Add & Close" the COM Server’s status will be displayed in the Main Window. The OPC COM DA Server is connected immediately, and the connection status of the server should show "Connected".
