3.11 Data registers D
(1) Data registers are memories that can store numerical data (-32768 to 32767 or
H0000 to HFFFF) in the built-in PLC function.
One point of data register consists of 16 bits and allows data to be read/written in
units of 16 bits.
Fig 3.20 Data Register Structure
(2) The data stored once by the sequence program is maintained until other data is
stored.
(3) If more data registers are needed, the unused timers (T) and counters (C) can be
used as data registers.
