Chapter 3 Creating Generic Modules in AbRioCfg Software
Generic Module
Configuration File The Generic Module configuration file consists of these sections.
– the configuration block transfer write (BTW)
– the data block transfer read
– the data block transfer write
Most configuration files have a configuration block transfer write.
Some may have both data block transfer read and data block transfer
write sections; others will have just one or the other. The maximum
size for each section is 64 words of data.
You can add comments to the file by preceding them with a
semicolon. Comments can be added to the end of an existing line or
can occupy separate lines. The configuration file can be created as a
text file or as a spreadsheet using a program like Excel and saved as a
CSV file.
To use a text file, separate the data fields with commas. To use a
spreadsheet, put the data values in separate columns.
Configuration Block Transfer Write
The configuration block transfer write section (Config BTW) contains
the data that is sent to the module to set how it operates. The
configuration block transfer write is sent:
at powerup
when communication is restored after being lost
when the remote I/O network switches from program to run
The first line of the configuration block transfer write is the keyword
“configbtw”, followed by the block transfer length, in words.
This is followed by data definitions that consist of an offset and a
value.
IMPORTANT The length of a CSV filename must not exceed 31 characters.
TIP
Sample configuration files are available for your use. The files
are located in the \GenProfile directory on the supplied
1757-ABRIO CD.
