DINT_TO_BYTE
This function converts a DINT variable to a BYTE variable.
If you omit an input or output parameter, a building error will occur.
This function converts DINT data In to BYTE data Out .
To convert BYTE data to DINT data, refer to BYTE_TO_DINT.
• The input condition depends on whether the output is safety data or standard data. If the condition is
not met, a building error will occur.
• If you set a safety data type variable for the output terminal, set a safety data type variable for the
input terminal as well.
• If you set a standard data type variable for the output terminal, you can set either a safety data type
variable or a standard data type variable for the input terminal.
• If the input value is not DINT#0 to DINT#255, a cast error will occur and the program will stop.
