Encoding from 256 to 8 bits

Redundant Universal

(S): Head number of the device where the data to be encoded is stored (Device name)

(D): Number of the device where the encoding result will be stored (BIN 16 bits)

Valid bit length (1 to 8), 0: No processing (BIN 16 bits)

Internal device

Processing details

• Stores the binary value corresponding to the bits which are "1" included in the 2

1 0 0 0 0 0 0

• The value of n can be designated at between 1 and 8.

• If n=0, there will be no operation, and the contents of (D) will not change.

• Bit devices are treated as 1 bit, and word devices as 16 bits.

• If more than 1 bit is at 1, processing will be conducted at the upper bit location.

Operation error

• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.

Error details

The value of n is other than 0 to 8. All data 2

bits from (S) exceeds the range of the corresponding device.

(Binary value = 6)

bits from (S) is "0".

-bit data of (S) to (D).
