Description
232
When CIO 000001 is ON in the following example, first the signed BCD data for-
mat and range in D00300 are checked against data control word "0003" (first
operand). If the check is okay, the signed BCD data in D00300 is converted to
binary and output to D00400.
D00300 D00400
Operand Data Areas
C: Control word
S: Source word
D: Destination word
When the execution condition is OFF, BCDS(276) is not executed. When the
execution condition is ON, BCDS(276) converts the data in a specified source
word (S) from signed binary to signed BCD, and outputs the results to a specified
destination word (C). The format of the destination word is determined by the
contents of the control word (C).
Note Special I/O Units sometimes require input of signed BCD data. BCDS(276) or
BDSL(278) can be used to easily convert signed binary data to signed BCD
data.
The output data format and range designations for the various control word con-
tents are as follows:
When C = 0000 (Output Data Range: –999 to 999 BCD)
When C = 0001 (Output Data Range: –7999 to 7999 BCD)
