Data Link Configuration
Section Format
This appendix explains how to structure the Data Link Configuration
section of your Device Configuration
.ini
file.
The Data Link Configuration section of your Windows
.ini
Device
Configuration file must be converted to C code and linked with your
application before the Round Card can communicate on the Fieldbus
network. The code generated by running this file through the
Configuration Generator automatically configures your board. When a
parameter is changed over the Fieldbus, the parameter is updated in
nonvolatile memory.
Following is a description of the format of the Data Link Configuration
section.
The first line of the Data Link Configuration section is as follows:
[Data Link]
The general line format for all other lines is as follows:
variable=value

link master device.
