2. Octal number (OCT)
The external input terminal numbers and the external output terminal numbers on a DVP-20PM series
motion controller are octal numbers.
 External input terminals: X0~X7, X10~X17… (Device numbers)
 External output terminals: Y0~Y7, Y10~Y17… (Device numbers)
3. Decimal number (DEC)
 A decimal number can be used as the setting value of a timer, or the setting value of a counter, e.g.
TMR T0 K50 (K indicates that the value following it is a constant.).
 A decimal number can be used as an S/M/T/C/D/V/Z/P device number, e.g. M10 and T30.
 A decimal number can be used as an operand in an applied instruction, e.g. MOV K123 D0 (K
indicates that the value following it is a constant.).
4. Binary-coded decimal number (BCD)
A decimal value is represented by a nibble or four bits, and therefore sixteen consecutive bits can
represent a four-digit decimal value. A binary-coded decimal number is mainly used as the input value
of a DIP switch, or the value displayed on a seven-segment display.
5. Hexadecimal Number (HEX)
 A hexadecimal number can be used as an operand in an applied instruction, e.g. MOV H1A2B D0
(H indicates that the value following it is a constant.).
Constant (K): A decimal number in a DVP-20PM series motion controller is generally preceded by K. For
example, K100 represents the decimal number 100.
Exception:
If K is used with an X/Y/M/S device, a nibble device, a byte device, a word device, or a
double word device will be formed.
Example:
K1Y10 represents a device composed of 4 bits, K2Y10 represents a device composed of
8 bits, K3Y10 represents a device composed of 12 bit, and K4Y10 represents a device
composed of 16 bits. K1M100 represents a device composed of 4 bits, K2M100
represents a device composed of 8 bits, K3M100 represents a device composed of 12
bit, and K4M100 represents a device composed of 16 bits.
Constant (H): A hexadecimal number in a DVP-20PM series motion controller is generally preceded by H.
For example, the hexadecimal number H100 represents the decimal number 256.
Floating-point number (F): A floating-point number in a DVP-20PM series motion controller is generally
preceded by F. For example, the floating-point number F3.123 represents
3.123.
