9.13 SIMATIC Conversion Instructions
BCD to Integer, Integer to BCD
The BCD to Integer instruction converts the input
Binary-Coded Decimal (IN) to an integer value and loads
the result into the variable specified by OUT. The valid
range for IN is 0 to 9999 BCD.
The Integer to BCD instruction converts the input integer
value (IN) to a Binary-Coded Decimal and loads the
result into the variable specified by OUT. The valid range
for IN is 0 to 9999 integer.
Error conditions that set ENO = 0: SM1.6 (BCD error),
SM4.3 (run-time), 0006 (indirect address)
These instructions affect the following Special Memory
bits: SM1.6 (invalid BCD)

Double Integer to Real
The Double Integer to Real instruction converts a
32-bit, signed integer (IN) into a 32-bit real number and
places the result into the variable specified by OUT.
