25 TYPE CONVERSION FUNCTIONS
25.62 Converting Bit Array to DINT
25.62 Converting Bit Array to DINT
BITARR_TO_DINT(_E)
These functions convert the specified number of bits in a bit array to a DINT data type value.
Setting data
■Description, type, data type
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 32-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.
*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.
