DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming
• Constant K:
Decimal value in PLC operation is attached with an “K”, e.g. K100 indicates the value 100 in
Decimal format.
Exception:
When constant K is used with bit devices X, Y, M, S, the value specifed after K indicates
the groups of 4-bit unit, which forms a digit(4-bit), byte(8 bit), word(16bit), or double
word(32-bit) data, e.g. K2Y10, K4M100, representing Y10 ~ Y17 and M100~M115.
4. BCD (Binary Coded Decimal)
BCD format takes 1 digit or 4 bits to indicate a Decimal value, so that data of consecutive 16
bits indicates a 4-digit decimal value. Used mainly for reading values from DIP switches or
sending data to 7-segement displays
5. Hexadecimal Number, HEX
DVP-PLC appies Hexadecimal operation in situations below:
• For use of operand in API instructions, e.g. MOV H1A2B D0。(H value)
• Constant H:
Hexadecimal value in PLC operation is attached with an “H”, e.g. H100 indicates the value
100 in Hex format.
