Program Example
(1) The following program decodes the 3 bits from X0 and stores the results at M10 when X20 is ON.
[Ladder Mode] [List Mode]
[Operation]
: Head number of the device where the data to be encoded is stored (Device name)
: Number of the device where the encoding result will be stored (BIN 16 bits)
n : Valid bit length (1 to 8), 0: No processing (BIN 16 bits)
Function
(1) Stores the binary value corresponding to the bits which are "1" included in the 2
n
-bit data of to .
(2) The value of n can be designated at between 1 and 8.
(3) If n 0, there will be no operation, and the contents of will not change.
(4) Bit devices are treated as 1 bit, and word devices as 16 bits.
(5) If more than 1 bit is at 1, processing will be conducted at the upper bit location.
