D.4.3 Value, Constant [K] / [H]

Constant

K	Decimal	K-32,768 ~ K32,767 (16-bit operation)
H	Hexadecimal	H0000 ~ HFFFF (16-bit operation)

There are five value types for DVP-PLC to use by the different control destination. The following is the explanation of value types.

1.Binary Number (BIN)

It uses binary system for the PLC internal operation or storage. The relative information of binary system is in the following.

Bit	: Bit is the basic unit of binary system, the status are 1 or 0.
Nibble	: It is made up of continuous 4 bits, such as b3~b0. It can be used to represent
	number 0~9 of decimal or 0~F of hexadecimal.
Byte	: It is made up of continuous 2 nibbles, i.e. 8 bits, b7~b0. It can used to represent
	00~FF of hexadecimal system.
Word	: It is made up of continuous 2 bytes, i.e. 16 bits, b15~b0. It can used to represent
	0000~FFFF of hexadecimal system.
Double	: It is made up of continuous 2 words, i.e. 32 bits, b31~b0. It can used to
Word	represent 00000000~FFFFFFFF of hexadecimal system.

The relations among bit, nibble, byte, word, and double word of binary number are shown as follows.

		W1	DW		W0			Double Word
								Word
	BY3		BY2		BY1		BY0	Byte
NB7	NB6	NB5	NB4	NB3	NB2	NB1	NB0
								Nibble
								Bit

2.Octal Number (OCT)

The numbers of external input and output terminal of DVP-PLC use octal number.

Example:

External input: X0~X7, X10~X17…(device number)
