15 TYPE CONVERSION FUNCTIONS
15.52 Converting DINT to Bit Array
15.52 Converting DINT to Bit Array
DINT_TO_BITARR(_E)
These functions output low-order (n) bits of DINT type data to a bit array.
â– Descriptions, types, and data types
â– Operation processing
• These functions output low-order (n) bits of ANY 32 type data specified to (s) to (d).
• Output bits beyond the specified number of bits are not changed.
â– 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.
*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.
There is no operation error.
