Processing details
■Operation processing
• Concatenates the character string input to (s2) to (s28) following the one input to (s1), and outputs the operation result from
(d).
This function concatenates character string (s2) to (s28) with ignoring '00H', which indicates the end of character string (s1).
If the concatenated character string has over 255 bytes, the character string up to 255 bytes is output.

• The values to be input to (s1) and (s2) to (s28) are string type data within the range from 0 to 255 bytes.
• The number of pins of (s) can be changed in the range from 2 to 28.
■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.
