Note: For XD5 firmware version V3.4.6 and above, data register D ranges from D0 to
D69999;
XD5 firmware version below V3.4.6, and data register D ranges from D0 to D59999.
Data register is used to store data; it includes16 bits(the higheset bit is sign bit) and32 bits.
(32 bits contains two registers, the highest bit is sign bit)
16-bits register range is -32,768 ~ +32,767
Read and write the register data through instruction or other device such as HMI.

32 bits value is consisted of two continuous registers. The range is -2147483648 ~
2147483647. For example: (D1 D0) D1 is high16 bits, D0 is low16 bits.
For32 bits register, if the low 16-bits are appointed, such as D0, then D1 will be the high16
bits automatically. The address of low 16-bits register must be even number.
