registers
1)
The number of points noted above is the number reserved as the calculation memory. The actual number of
points available for use is determined by the hardware configuration.
2)
There are hold and non-hold type memory areas. When the power supply turns off or the mode is changed
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
"Backup and Clock/Calendar Functions" on page 42.
3)
The number of points for timer and counter relays can be changed using system register 5. The numbers in
the table are the default settings.

Function
Code for specifying 32 external input points
as a double word (32 bits) of data.
Code for specifying 32 external output
points as a double word (32 bits) of data.
Code for specifying 32 internal relay points
as a double word (32 bits) of data.
Code for specifying 32 link relay points as a
double word (32 bits) of data.
Data memory used in a program. Data is
handled in 32-bit units (double word).
Data memory shared by multiple PLCs
connected using PLC link. Data is handled
in 32-bit units (double word).
Data memory for storing the set values of
timers or counters. The values are stored
by timer/counter number.
Data memory for storing the elapsed values
during operation of timers or counters. The
values are stored by timer/counter number.
Data memory for storing settings and error
codes.
