Auxiliary Area Appendix C
Note 1. CJ1M CPU Units with built-in I/O only.
2. These Auxiliary Area bits/words are not to be written by the user. The number of resends and re-
sponse monitoring time must be set by the user in the FB communications instructions settings in the
PLC Setup, particularly when using function blocks from the OMRON FB Library to execute FINS
messages or DeviceNet explicit messages communications. The values set in the Settings for
OMRON FB Library in the PLC Setup will be automatically stored in the related Auxiliary Area words
A580 to A582 and used by the function blocks from the OMRON FB Library.
A540
(See
note 1.)
A54000 Pulse Out-
put 0 Reset
Bit
The pulse output 0 PV (contained in
A276 and A277) will be cleared when
this bit is turned from OFF to ON.
--- Retained Cleared ---
A54008 Pulse Out-
put 0 CW
Limit Input
Signal Flag
This is the CW limit input signal for
pulse output 0, which is used in the
origin search. To use this signal,
write the input from the actual sensor
as an input condition in the ladder
program and output the result to this
flag.
--- ---
A54009 Pulse Out-
put 0 CCW
Limit Input
Signal Flag
This is the CCW limit input signal for
pulse output 0, which is used in the
origin search. To use this signal,
write the input from the actual sensor
as an input condition in the ladder
program and output the result to this
flag.

A541
(See
note 1.)
A54100 Pulse Out-
put 1 Reset
Bit
The pulse output 1 PV (contained in
A278 and A279) will be cleared when
this bit is turned from OFF to ON.
--- Retained Cleared ---
A54108 Pulse Out-
put 1 CW
Limit Input
Signal Flag
This is the CW limit input signal for
pulse output 1, which is used in the
origin search. To use this signal,
write the input from the actual sensor
as an input condition in the ladder
program and output the result to this
flag.

A54109 Pulse Out-
put 1 CCW
Limit Input
Signal Flag
This is the CCW limit input signal for
pulse output 1, which is used in the
origin search. To use this signal,
write the input from the actual sensor
as an input condition in the ladder
program and output the result to this
flag.
