5-19-11SIGNED BINARY TO BCD SCALING – SCL2(––)
Limitations This instruction is available in the CQM1-CPU4@-E/-EV1 only.
P1 through P1+2 must be in the same data area.
DM 6144 to DM 6655 cannot be used for R.
Description SCL2(––) is used to linearly convert a 4-digit signed hexadecimal value to a 4-
digit BCD value. Unlike BCD(24), which converts a 4-digit hexadecimal value
to its 4-digit BCD equivalent (S
hex
→ S
BCD
), SCL2(––) can convert the signed
hexadecimal value according to a specified linear relationship. The conversion
line is defined by the x-intercept and the slope of the line specified in the
parameter words P1 to P1+2.
When the execution condition is OFF, SCL2(––) is not executed. When the
execution condition is ON, SCL2(––) converts the 4-digit signed hexadecimal
value in S to the 4-digit BCD value on the line defined by the x-intercept (P1,
0) and the slope (P1+2
÷ P1+1) and places the results in R. The result is
rounded off to the nearest integer.
If the result is negative, then CY is set to 1. If the result is less than –9999,
then –9999 is written to R. If the result is greater than 9999, then 9999 is writ-
ten to R.
