(Process) (Redundant)
These functions convert the specified number of bits in a bit array to an INT data type value.

Setting data
■Description, type, data type
Argument Description
EN Execution condition (TRUE: Executed, FALSE: Not executed)
s (BitArr) Input (An element can be specified by a variable.)
n Number of bits (4, 8, 12, or 16)
ENO Output status (TRUE: Normal, FALSE: Abnormal or operation stop)
d Output
Processing details
■Operation processing
• These functions convert the number of bits specified by (n) starting from the bit array element input to (s) to any 16-bit data
type value, and output the converted value from (d).
• Zeros (0s) are set for all the bits exceeding the specified number of bits.
■Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (executed)
FALSE (not executed)
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
There is no operation error.
