Copying the Bit Array
CPY_BITARR(_E)
These functions copy the bit array by the specified number of bits.

Description, type, data type
Processing details
■ Operation processing
• These functions output the bit array (number of (n) bits) specified by (s) to (d).
■
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.
*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.
