word (signed), double word (signed) type conversion
BCD_TO_INT(_E), BCD_TO_DINT(_E)
(2) BCD_TO_DINT, BCD_TO_DINT_E
(a) Converts BCD type data input to into double word (signed) type data, and outputs
the operation result from .
(b) The value to be input to is double word (unsigned)/32-bit string type data within the
range from 0
H to 99999999H (0 to 9 for each digit).
Operation result
(1) Function without EN/ENO
An operation is executed and the operation value is output from .
(2) Function with EN/ENO
The following table shows the executing conditions and operation results.
*1 When FALSE is output from ENO, the data output from is undefined.
In this case, create a program so that the data output from is not used.
