DVP - ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

zConstant 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:

zFor use of operand in API instructions, e.g. MOV H1A2B D0。(H value)

zConstant H:

Hexadecimal value in PLC operation is attached with an “H”, e.g. H100 indicates the value 100 in Hex format.
