Processing details
■Operation processing
• Converts BCD type data input to (s) into string type data, and outputs the operation result from (d).
When word (unsigned)/16-bit string type is specified for (s).
s
9999
H
Word (unsigned)/16-bit string type
When double word (unsigned)/32-bit string type is specified for (s).
s
99999999
H
Double word(unsigned)/32-bit string type
• Word (unsigned)/16-bit string type, double word (unsigned)/32-bit string type data can be specified for (d). Bit type cannot
be specified.
• When SM701 (signal for switching the number of output characters) is OFF, "00H" is stored to the end of the character
string.
■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.
