Editing G File Data
Edit the data in the G file 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, edit data at the word level:
G1:1 = 234 (decimal format)
G1:1 = 00EA (hex/bcd format)
With the binary format, edit data at the bit level:
G1/19 = 1
Important: The processor automatically configures word 0 of the G
file according to the particular specialty I/O module.
You cannot edit word 0.
