Bit column -> bit line conversion
This FP instruction converts a bit column out of an address range starting at input s_Start and returns each bit in a bit line at output d. The bit position is specified at input n_Pos (range 0–15). This instruction is the reversion of FP_WORD_TO_BITCOLUMN.
Input
Starting address of the bit column
Bit position (range 0–15)
Output
Result
if the area specified using the index modifier exceeds the limit.
if 0 ³ n_Pos > 15
if s_Start is out of range
if the area specified using the index modifier exceeds the limit.
if 0 ³ n_Pos > 15
if s_Start is out of range
All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.
VAR
bStart: BOOL:=FALSE;
(*activates the function*)
iPosition: INT:=10;
(*specifies the position
of the column*)
wBit_combination: WORD:=16#0;
(*result after a 0->1 leading
edge from start:
2#1100011110111000*)
END_VAR
When the variable bStart is set to TRUE, the function is carried out. The bit column at bit position 10 of the data starting at DT10 is output as 0101 0001 1101 1001 at d.
