—>BCD-4 (INT)
The Convert to BCD-4 function is used to output the 4-digit BCD equivalent of signed integer data.
The original data is not changed by this function.
Data can be converted to BCD format to drive BCD-encoded LED displays or presets to external
devices such as high-speed counters.
When the function receives power flow, it performs the conversion, making the result available via
output Q. The function passes power flow when power is received, unless the specified conversion
would result in a value that is outside the range 0 to 9999.
