Issue
BACnet Service does not start after enabling BACnet IP on a UNC station. The following error messages are seen in the UNC standard output.
ERROR: Error initializing IP link layer. [IpLinkLayer.updateLocalAddress] java.lang.NoSuchMethodError: tridium/nre/Platform.getLocalHost()Ljava/net/InetAddress; ERROR: Cannot startService [Sys: BACnetService [12] BACnetService] java.lang.NullPointerException ERROR: Run error [BTrprt] java.lang.NullPointerException
Product Line
TAC IA Series
Environment
I/A Series UNC running at version r2.301.5xx prior to version r2.301.535 with BACnet 2.305.535a.
Cause
Most I/A Series R2 Niagara JAR files are backward compatible. Refer to Can jar files from Niagara R2 version 532 be used with a UNC running version 330? for details.
There were some changes to the BACnet service IP to support the new JACE-603/645 platforms. Because of these changes to the R2 core, the BACnet 2.305.535a JAR file is not backward compatible.
Resolution
Upgrade the UNC to version r2.301.535. Refer to the Installation Instructions for upgrade procedure.
