I/A Series R2 – ERROR: run [DiscoverySender] java.net.SocketException in Output Window

[Product_Support]

Issue

The I/A Series R2 station output window continuously displays the following error:

ERROR: run [DiscoverySender] - java.net.SocketException

The station appears to be running, but the heartbeat LED remains solid.

Product Line

TAC IA Series

Environment

I/A Series R2 UNC

Cause

The error occurs because the Enable Announcement feature is not implemented in Niagara R2. When enabled, it triggers the DiscoverySender process, resulting in a socket exception.

Resolution

1. Open the station database in Workbench.
2. Highlight the station name and go to the Config tab.
3. Locate the property enableAnnouncement.
4. Set enableAnnouncement = false.

   

5. Save changes and restart the station (reboot the UNC).
