■Descriptions, types, and data types
Argument Description
EN Execution condition (TRUE: Execution, FALSE: Stop)
s Input
n Only a constant 4, 8, 12 or 16 can be specified.
ENO Output status (TRUE: Normal, FALSE: Abnormal)
d(INT_TO_BITARR(_E)) Output (Variables are available for element specification.)
Processing details
■Operation processing
• These functions output low-order (n) bits of ANY 16 type data specified to (s).
• Output bits beyond the specified number of bits are not changed.
■Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
