BIN Mode
The decimal value is assigned to input
>I1
. The decimal value is represented as
a BCD coded value. The BCD coded value is interpreted as a hexadecimal
value and output as a decimal value at output QV>.
IMPORTANT
The highest binary value represented in BCD is 1001 = 9.
All other higher binary values from 1010 to 1111 are output
as 9. This behavior is correct as BCD encoders do not
normally generate these values.
IMPORTANT
Bit 32 is the sign bit. Bit 32 = 1 → Sign = Minus.
IMPORTANT
Values greater than 161061273 are output as 9999999.
Values less than -161061273 are output as
-9999999. The working range of the function block has
been exceeded.
