(2) The following program converts the hexadecimal, 8-digit ASCII data set at D20 to D23 to BIN values, and stores the
result at D10 and D11.
[Ladder Mode] [List Mode]
[Operation]
: ASCII data to be converted to BCD value or head number of the devices where the ASCII data is stored (character string)
: Head number of the devices where the conversion result will be stored (BCD 4 digits/8 digits)
Function
DABCD
(1) Converts decimal ASCII data stored in the area starting from device number designated by into 4-digit BCD data, and
stores at device number designated by .
For example, if the ASCII code of 8765
H
is designated for the area starting from , the operation results would be stored
at in the following manner:
(2) The ASCII data designated by to +1 can be in the range of from 0 to 9999.
(3) The ASCII code set at each digit can be in the range of from "30
H
" to "39
H
".
(4) If ASCII code for individual digits is "20
H
" or "00
H
", it is processed as "30
H
".
