Allen-Bradley 1747-SN - G Files

M0–M1 Files and G Files B–9
Publication 17476.6 - July 1996
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. You cannot access G files under the Monitor
File 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 Using APS Software
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 except that you must specify the ID code of the specialty
I/O module), the following functions appear at the bottom of the
APS screen:
