(2) Performing latch clear
To perform latch clear, operate the RUN/STOP key switch as follows.
(3) Removing a memory card while the PLC power is ON:
When removing a memory card with the PLC power ON, operate the memory card in/
out switch as follows:
1) Turn the RUN/STOP key switch to L.CLR three times.

.........Ready for latch
clear
Display on Q3ACPU, Q4ACPU
: Displays "L.CLR RDY".
2) Turn the RUN/STOP key switch to "L.CLR" once again.
USR LED
: ON for 2 seconds
.........Latch clear
completed
Display on Q3ACPU, Q4ACPU
: Displays "L.CLR OK"
for 2 seconds
POINT
(1) The latch clear operation can be set enabled or disabled for each device in
the device setting in the parameter mode.
(2) Remote latch clear executed by the GPP function is an alternative method
other than using the RUN/STOP key switch. (Refer to Section 10.6.5).
1) In/out switch: ON.

Removal of memory card
POINT
(1) The LED in the in/out switch may not come OFF if the memory card is being
used for a CPU module system function (sampling trace, status latch, etc.) or
by a program. In this case, abort the function or program that is using the
memory card. After aborting it, confirm that the LED in the in/out switch has
gone OFF, then remove the memory card.
(2) When a file register, local device or breakdown history set with parameters is
present, the memory card cannot be removed.
Even if the memory card in/out switch is turned OFF, its built-in LED does not
turn OFF. When the file register is set to "Not used" with the QDRSET (P)
instruction, the memory card can be removed.
(3) After removing the memory card, do not turn the memory card in/out switch
ON. Doing so will result in an error.
