Notes
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) If no battery is used, only the fixed area is backed up
(counters 16 points: C1008 to C1023, internal relays 128
points: R900 to R97F, data registers 55 words: DT32710 to
DT32764). When the optional battery is used, all area can be
backed up. Areas to be held and not held can be specified
using the system registers.
3) The points for the timer and counter can be changed by the
setting of system register 5. The number given in the table are
the numbers when system register 5 is at its default setting.
