Echelon FTXL - Manual (Page 75)

FTXL User’s Guide 63
The LonCpTypes.h file defines configuration property types, and includes
standard or user configuration property types (SCPTs or UCPTs) for
configuration properties implemented within configuration files.
Either of these files might be empty if your application does not use either
network variables or configuration properties.
FtxlDev.h
The FtxlDev.h file is the main header file that the LonTalk Interface Developer
utility produces. This file provides the definitions that are required for your
application code to interface with the application framework and the FTXL
LonTalk API, including C extern references to public functions, variables, and
constants generated by the LonTalk Interface Developer utility.
You should include this file with all source files that your application uses, but
you do not normally have to edit this file. Any manual changes to this file are not
retained when you rerun the LonTalk Interface Developer utility. The file
contains comments that describe how you can override some of the preferences
and assumptions made by the utility.
FtxlDev.c
The FtxlDev.c file is the main source file that the LonTalk Interface Developer
utility produces. This file includes the FtxlDev.h file header file, declares the
network variables, configuration properties, and configuration files (where
applicable).
It defines the device’s LonInit() function. It also defines variables and constants,
including the network variable table, the device’s initialization data block, and a
number of utility functions.
You must compile and link this file with your application, but you do not
normally have to edit this file. Any manual changes to this file are not retained
when you rerun the LonTalk Interface Developer utility, but the file contains
comments that describe how you can override some of the preferences and
assumptions made by the utility.
project.xif and project.xfb
The LonTalk Interface Developer utility generates the device interface file for
your project in two formats:
• project .xif (a text file)
• project .xfb (a binary file)
For both files, project is the name of the FTXL project that you specified in the
Welcome to LonTalk Interface Developer window of the LonTalk Interface
Developer utility. Thus, these files have the same name as the FTXL project file
(.lidprj extension).
These files comply with the L
ON
M
ARK
device interface revision 4.401 format.
Important: If your device is defined with a non-standard program ID, the device
interface file cannot contain interoperable L
ON M ARK constructs.
