Note1)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.
Note2)If no battery is ued, 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). Writing
is available up to 10000 times. Then 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. If an area is held when
the battery is not installed, the value of data may be indefinite as it is not cleared to 0 when the
power is turned on. When the battery ran out of the power, the data at the hold area will be
indefinite.
Note3)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.
