Need a BACnet string object in StruxureWare Building Operation it doesn't seems to be possible to create today, only SmartStruxure string object is possible to create.
StruxureWare Building Operation 1.3
The reason is that we have implemented BACnet standard protocol revision 6 in SmartStruxure and the string object is added in BACnet standard protocol revision 10.
A BACnet standard protocol revision version higher than 10 will be implemented in a future SmartStruxure version. Today it is not decided in which SmartStruxure version it will be implemented.
