25 TYPE CONVERSION FUNCTIONS
25.64 Converting DINT to Bit Array
25.64 Converting DINT to Bit Array
DINT_TO_BITARR(_E)
These functions output the lower n bits of the DINT data type value to the bit array.
Setting data
■Description, type, data type
Processing details
■Operation processing
• These functions output the lower (n) bits of any 32-bit data type value specified by (s) to (d).
• The output bits beyond the specified number of bits are not changed.
■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.
