DOUBLE SIGNED BINARY-TO-BCD: BDSL(278)

Ladder Symbol
(278)
BDSL C S D
Variations
BDSL(278)
Description
248
Operand Data Areas
C: Control word
S: 1st source word
D: 1st destination word
When the execution condition is OFF, BDSL(278) is not executed. When the
execution condition is ON, BDSL(278) converts the data in specified words (S
and S+1) from double signed binary to double signed BCD, and outputs the re-
sult to specified destination words (D and D+1). The format of the destination
word is determined by the contents of the control word (C).
Note Special I/O Units sometimes 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 9999 to 999 9999 BCD)
S+1 S
When C = 0001 (Output Data Range: –7999 9999 to 7999 9999 BCD)
S+1 S
When C = 0002 (Output Data Range: –999 9999 to 9999 9999 BCD)
S+1
When C = 0003 (Output Data Range: –1999 9999 to 9999 9999 BCD)
S+1
