5.2.9 BCD (FNC18)
Operation 1:
(Applicable to all units)
The binar
y
source data (S) is converted into an
equivalent BCD number and stored at the
destination device (D). If the converted BCD number
exceeds the operational ran
g
es of 0 to 9,999 (16 bit
operation) and 0 to 99,999,999 (32 bit operation) an error will occur.This instruction can be
used to output data directl
y
to a seven se
g
ment displa
y
.
Operation 2:
(Applicable units: FX
(2C)
)
This function is equivalent to FNC 118 EBCD Data
(S)is converted from ‘floatin
g
point’ format to
‘scientific format’ (D). This instruction requires
double word (32 bit) operation and data re
g
isters as
devices (S)and (D)to operate correctl
y
.
5.2.10 BIN (FNC 19)
Operation 1:
(Applicable to all units)
The BCD source data (S) is converted into an
equivalent binar
y
number and stored at the
destination device (D). If the source data is not
provided in a BCD format an error will occur. This instruction can be used to read in data
directl
y
from thumbwheel switches.
Operation 2:
(Applicable units: FX
(2C)
)
This function is equivalent to FNC 119 EBIN Data
(S) is converted from ‘scientific format’ to ‘floatin
g
point’ format (D). This instruction requires double
word (32 bit) operation and data re
g
isters as
devices (S)and (D)to operate correctl
y
.
