Issue
EcoStruxure Building Operation Automation Server, Enterprise Server and BACnet object names limitation
Dragging converted I/NET TGML graphics into Workstation causes Workstation to crash with following message:
Exception message: Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.

Product Line
EcoStruxure Building Operation
Environment
Building Operation Workstation
Cause
The number of characters and the use of special characters in a EcoStruxure Building Operation object name and EcoStruxure Building Operation BACnet objects names
Resolution
Refer to the Webhelp Object Names topic for information on naming restrictions
The statements in Webhelp also apply to EcoStruxure Building Operation BACnet objects unless is it a Continuum b3 object.
If you are creating a Continuum b3 object etc., the b3 object display name is limited to 16 characters consisting solely of letters, digits, and underscores (as per Continuum limitation).
Basically, any objects you create for Continuum, for example, a 'BACnet Analog Input (Continuum)' will be subjected to the Continuum limitation.
If you add a standard 'BACnet Analog Input' into an Automation Server or an Enterprise Server, then it is not limited by the Continuum limitation of 16 characters.
The most common issue when bringing I/NET TGML converted graphics into Workstation is not checking for spaces at either the beginning or end of the converted file name. Make sure there are no spaces (white space) before or after any characters of the file name before copying into Workstation.
