Allen-Bradley 1747-SN - Configuring M0-M1 Files Using APS Software

M0–M1 Files and G FilesB–2
Publication 17476.6 - July 1996
Complete the following steps to configure the M0 and M1 files:
1. Press
[F9], Specialty I/O Configuration. The following functions
appear:
F1 F3 F5 F7
ISR
NUMBER
MODIFY
G FILE
ADVNCD
SETUP
G FILE
SIZE
2. Press [F5], Advanced Setup. The following functions appear:
F1
INPUT

F6
M1 FILE

3. Press [F5], then enter the number of M0 file words required (the
required number is listed in the user manual for the specific
specialty I/O module).
4. Press
[F6], then enter the number of M1 file words required (the
required number is listed in the user manual for the specific
specialty I/O module).
The specialty I/O module may require that you also configure the G
file and specify an ISR (interrupt subroutine) number. These tasks
are accomplished with function keys F1, F3, and F7 shown in step 1
above. G files are discussed later in this appendix.
Addressing M0-M1 Files
The addressing format for M0 and M1 files is below:
Mf:e.s/b
Where M = module
f = file type (0 or 1)
e = slot (130)
s = word (0 to max. supplied by module)
b = bit (015)
Restrictions on Using M0M1 Data File Addresses
M0 and M1 data file addresses can be used in all instructions except
the OSR instruction and the instruction parameters noted below:
Instruction Parameter (uses file indicator #)
BSL, BSR File (bit array)
SQO, SQC, SQL File (sequencer file)
LFL, LFU LIFO (stack)
FFL, FFU FIFO (stack)
