The "DEC_TO_BCD" function block allows decimal numbers to be converted to BCD format. The number to be converted is checked for the reliability of the values.
VAR_INPUT
VAR_INPUT
START : BOOL;
DIN : BYTE;
END_VARSTART: The function block is activated by a positive edge at this input.
DIN: The decimal number requiring conversion.
VAR_OUTPUT
VAR_OUTPUT
BUSY : BOOL;
ERR : BOOL;
ERRID : UDINT;
BOUT : BYTE;
END_VARBUSY: This input is set at the start of the conversion procedure, and remains set until the conversion has been completed. Once the BUSY output has been reset, the BCD value is available at the BOUT output.
ERR: This variable is set to TRUE if an error occurs.
ERRID: Error code.
BOUT: The converted variable in BCD format is available at this output if the process is successful.
