Panasonic FP Series Programming Manual page 1260

The number of points noted above is the number reserved as the calculation memory. The actual number of
1)
points available for use is determined by the hardware configuration.
There are hold and non-hold type memory areas. When the power supply turns off or the mode is changed
2)
from RUN to PROG mode, hold type areas are stored and non-hold type areas are reset.
C10/C14/C16/C32:
The hold type and non-hold type areas are fixed. For information on the size of each area, refer to the
performance specifications.
T32/F32:
The settings of the hold type areas and non-hold type areas can be changed using the system registers.
T32:
If the battery is empty and additional hold areas have been defined, the hold/non-hold operation becomes
unstable. The data value will become indefinite. It is cleared to 0 the next time the power is turned on. See.
The number of points for timer and counter relays can be changed using system register 5. The numbers in
3)
the table are the default settings.

%IX0.0– Turn on or off based on external
%IX73.15 input.
%QX0.0– Turn on or off external outputs
%QX73.15 based on the operation result.
%MX0.0– Used internally by the PLC
%MX0.255.15 program to store bit information.
%MX7.0.0– Shared by multiple PLCs
%MX7.63.15 connected using PLC link.
%MX1.0– Turn on when the value set with
%MX1.1007/ a TM instruction for the timer with
%MX2.1008– the same number has reached 0.
%MX2.1023
%MX2.1008– Turn on when the value set with
%MX2.1023/ a CT instruction for the counter
%MX1.0– with the same number has
%MX1.1007 reached 0.
%MX0.900.0– Turn on or off based on specific
%MX0.910.15 conditions. Used internally as a
flag.
