G Data Files - Specialty I/O
Modules
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.
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. With the decimal and hex/bcd formats, you
edit data at the word level.
• G1:1 = 234 (decimal format)
G1:1 = 00EA (hex/bcd format)
This rung is true for
the first scan after
powerup to unlatch
M0:2.1/1.
TIP
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.
