The name of a LON Network Variable (nvi or nvo SNVT) or a LON controller configuration constant (nci SNVT) contains a space.

Echelon standards do not allow spaces in network variable or configuration constant names.


Edit the application file removing any spaces or other non-supported characters from network variable and configuration constant names.
