M0-M1 Files and G Files B-9
G Files Some specialty I/O modules use G (configuration) files (indicated in
the specific specialty I/O module user’s manual). These files can be
thought of as the software equivalent of DIP switches.
The content of G files is accessed and edited offline under the I/O
Configuration function. Data you enter into the G file is passed on to
the specialty I/O module when you download the processor file and
enter the REM Run or any one of the REM Test modes.
Configuring G Files
The G file is configured as part of the I/O configuration procedure for
the processor file. After you have assigned the specialty I/O module to
a slot (the procedure is the same as assigning other modules), you
may click on the advanced configuration button in order to configure
the number of G file words.
Editing G File Data
Data in the G file must be edited according to your application and
the requirements of the specialty I/O module. You edit the data
offline under the I/O configuration function only.
IMPORTANT
Word 0 of the G file is configured automatically by
the processor according to the particular specialty I/O
module. Word 0 cannot be edited.
