Processing details
■Operation processing
• INT_TO_BITARR, INT_TO_BITARR_E
Outputs low-order n bits of word (signed) type or word (unsigned)/16-bit string type data specified for (s) to (d).
Only a constant 4, 8, 12 or 16 can be specified for n.
The output bits higher than the specified number of bits do not change.
• DINT_TO_BITARR, DINT_TO_BITARR_E
Outputs low-order n bits of double word (signed) type or double word (unsigned)/32-bit string type data specified for (s) to (d).
Only a constant 4, 8, 12, 16, 20, 24, 28 or 32 can be specified for n.
The output bits higher than the specified number of bits do not change.
■Operation result
• Function without EN/ENO
An operation is executed and the operation value is output from (d).
• Function with EN/ENO
The following table shows the executing conditions and operation results.
EN
TRUE (Operation execution)
FALSE (Operation stop)
*1 When FALSE is output from ENO, the data output from (d) is undefined. In this case, create a program so that the data output from (d) is
not used.
