4.4.7 Numeric Variable Data
These are output signals to specify numeric variable data.
Address Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Y+24 VDATA0: The first byte of the numeric variable data
Y+25 VDATA1: The 2nd byte of the numeric variable data
Y+26 VDATA2: The 3rd byte of the numeric variable data
Y+27 VDATA3: The 4th byte of the numeric variable data
Y+28 VDATA4: The 5th byte of the numeric variable data
Y+29 VDATA5: The 6th byte of the numeric variable data
Y+30 VDATA6: The 7th byte of the numeric variable data
Y+31 VDATA7: The 8th byte of the numeric variable data
• The numeric variable data is continuously stored from VDATA0.
The number of bytes used is specified with VDTLN0-4.
• The numeric variable data is a Little endian form (Intel form).
The numerical value is sequentially stored from the digit below.
(Example) Numeric type = Unsigned binary form, The
length(bytes) of numeric variable data = 4,
Numeric variable data = 123456 (Decimal)
= 1E240 (Hexadecimal)
Value(Hexadecimal )
VDATA0 40
VDATA1 E2
VDATA2 01
VDATA3 00
Numeric type = BCD form, The length(bytes) of numeric variable
data = 4,
Numeric variable data = 123456 (BCD)
Value(Hexadecimal )
VDATA0 56
VDATA1 34
VDATA2 12
VDATA3 00
• When numeric type (VTYPE0-1) is "Custom macro variable",
Mantissa is stored in VDATA0-3(four bytes), exponent is stored
in VDATA4-5(two bytes).
