Operating mode
BCD mode
The BCD value at I1 will be converted to a binary value and output at output QV. The bin-
ary value is displayed as a decimal value.
BIN mode
The binary value present at input I1 is converted to a BCD value and supplied at the out-
put QV. The binary value is displayed as a decimal value.
Description Note
BCD Converts a BCD value to a binary value.
BIN Converts a binary value to a BCD value.
Function block outputs
