IOM Hold Bit Status at
Startup
0: Cleared
1: Retained
Default: 0
This setting determines whether
or not the status of the IOM Hold
Bit (A50012) is retained at
startup.
When you want all of the data in
I/O Memory to be retained when
the power is turned on, turn ON
the IOM Hold Bit and set this
setting to 1 (ON).
Same as
CS/CJ-series
PLC.

Default: 0
This setting determines whether
or not the status of the Forced

tained at startup.
When you want all of the bits that
have been force-set or
force-reset to retain their forced
status when the power is turned
on, turn ON the Forced Status
Hold Bit and set this setting to 1
(ON).
Same as
CS/CJ-series
PLC.

the startup mode will be the mode
set on the Programming Con-
sole’s mode switch or the mode
set here in the PLC Setup. (If this
setting is PRCN and a Pro-
gramming Console isn’t con-
nected, the CPU Unit will auto-
matically enter PROGRAM mode
at startup.)

CPU Unit will
automatically
enter
PROGRAM
mode.
