Mitsubishi Electric MELSEC iQ-R Series Programming Manual page 1956

• Input a STRING data type value to (s1) and (s2) within the range of 0 to 255 bytes.
• Input an INT data type value to (n) within the range of 1 to 255, provided that it is within the number of characters in the
string input to (s1).
■Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (executed)
FALSE (not executed)
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
Error code Description
(SD0)
2820H There is no NULL code (00H) in each setting area specified by (s1) to (s28) in the device/label memory.
There is no NULL code (00H) in each setting area in the device/label memory in the device specified by (d) and later.
2821H The device numbers are overlapping between (s1) to (s28) and (d).
3405H The number of characters in the strings input to (s1) to (s28) exceeds 16383.
The number of characters in the strings input to (s1) to (s28) is 0.
The number of characters of the character string in the device specified by (d) exceeds 16383.
3406H The entire string after concatenate processing cannot be stored in the setting area specified by (d) in the device/label memory. (The
number of required points is insufficient.)
