• BCD_TO_DINT, BCD_TO_DINT_E
Converts BCD type data input to (s) into double word (signed) type data, and outputs the operation result from (d).

The value to be input to (s) is word (unsigned)/16-bit string type data within the range from 0H to 9999H (0 to 9 for each digit),
double word (unsigned)/32-bit string type data within the range from 0H to 99999999H (0 to 9 for each digit).
Word (unsigned)/16-bit string, double word (unsigned)/32-bit string type can be specified for (d). Bit type cannot be specified.
■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.
