Turn this bit ON to preserve the status
of the I/O Memory when shifting from
PROGRAM to RUN or MONITOR mode
or vice versa.
(If the status of the IOM Hold Bit itself is
preserved in the PLC Setup (IOM Hold
Bit Status), the status of the I/O Mem-
ory Area will be retained when the PLC
is turned ON or power is interrupted.)
Turn this bit ON to preserve the status
of bits that have been force-set or force-
reset when shifting between PRO-
GRAM and MONITOR or when the
power supply is turned ON.
Always use this bit in combination with
the IOM Hold Bit, i.e., A50012 must be
turned ON before A50013 is effective.
(If the status of the Forced Status Hold
Bit itself is preserved in the PLC Setup
(Forced Status Hold Bit Status), the sta-
tus of force-set and force-reset bits will
be retained when the PLC is turned ON
or power is interrupted.)
Turn this bit ON to reset the Error Log
Pointer (A300) to 00.
The contents of the Error Log Area
itself (A100 to A199) are not cleared.
(This bit is automatically reset to 0 after
the Error Log Pointer is reset.)
Turn this bit ON to turn OFF all outputs
from Basic I/O Units and Special I/O
Units. The INH indicator on the front of
the CPU Unit will light while this bit is
ON.
(The status of the Output OFF Bit is
retained through power interruptions.)
Turn these bits ON to restart (initialize)
the CPU Bus Unit with the correspond-
ing unit number. Bits 00 to 15 corre-
spond to unit numbers 0 to F.
When a restart bit is turned ON, the
corresponding CPU Bus Unit Initializing
Flag (A30200 to A30215) will be turned
ON. Both the restart bit and initializing
flag will be turned OFF automatically
when initialization is completed. Do not
turn the bit OFF from a Programming
Device or the ladder program.
Contains the task number of the
interrupt task with the maximum pro-
cessing time. Hexadecimal values
8000 to 80FF correspond to task
numbers 00 to FF. Bit 15 is turned
ON when an interrupt has occurred.
(This value is written after the inter-
rupt task with the max. processing
time is executed and cleared when
PLC operation begins.)
