Issue
When a XIF file contains NCI's (SCPT's and UCPT's) default values (NVVAL) must be described in the XIF file. In some cases if NCI's are present, but some or all NVVAL initializers are missing commissioning the device will fail.
For information regarding NCI's that are part of a FILE definition, please refer to Understanding the FILE part of a XIF file.
Product Line
EcoStruxure Building Operation, TAC Vista
Environment
- LonWorks
- XIF
Cause
When commissioning a device default values to configuration variables must be assigned. If the tool (TAC Vista, SmartStruxure, LonMaker, NL220) does not know what default value to assign, it can cause an error.
Resolution
Make sure all NCI's have proper initializers defined. Read XIF file - NVVAL initializers.pdf guide as reference.
Here is an example of a NVVAL section:
