Appendix A.4. XIF Generation
After start-up the FieldServer creates a XIF (version 4.0) according to the configuration loaded. This file is called fServer.xif
and can be uploaded from the FieldServer using the RuiNet utility.
The FieldServer’s XIF file is internally generated by the LonWorks driver using the information contained in the FieldServer’s
configuration file (CONFIG.CSV). It is not possible to download an externally created XIF file using NodeUtil or LonMaker
is also not possible to download any type of externally created network variables default values file. The FieldServer’s
configuration can be changed by uploading and editing the CONFIG.CSV file, and therefore the XIF file must be obtained by
uploading it from the FieldServer. Remember that this XIF file will change whenever the configuration file has been changed,
downloaded and the FieldServer restarted.
Appendix A.5. Configuration Properties
Configuration Properties are implemented on the FieldServer using configuration Network Variables. Configuration Network
Variables take the form of update inputs in order to be updated or read by a network management tool. Each Configuration
Network Variable will have its own Map Descriptor. Since the data carried by a Network Variable is intended as a
configuration property for other already declared non-configuration Network Variable(s), no Data Array needs to be assigned
to its Map Descriptor.
The following configuration property types are supported:
Apply gain to Input and Output Network Variable values via SNVT_nv_type
Add Offset values to Input and Output Network Variable Values via SNVT_nv_type
Enforce Minimum and Maximum Range on Network Variables
Set Update Rate on Active Network Variables
Set Throttling Mode (Min/MaxSendTime, DeltaValue) properties on Active Network Variables
Allow adjusting of scan interval on active LonWorks Map Descriptors (SCPTupdateRate (98))
SCPTGain (31) for Modbus Translations via SNVT_muldiv
Allow changing of the NV_Delta_Value (SCPTsndDelta (27))
Configuration Properties can be declared to belong to the entire Node, to an Object(s) or to a Network Variable(s). This
declaration defines the scope of the Configuration Property. Configuration Properties that belong to an Object are declared
as a part of the Object; Configuration Properties associated with a Network Variable(s) are declared as belonging to the
Network Variable(s) etc.
A Configuration Property’s Type and Responsible Map Descriptor(s) are declared by the Configuration Network Variable’s
self-documentation string as follows:
For linking to the entire node:
“&0, , 0\x80, *SCPT Index+”
Example: “&0, , 0\x80, 20”
