Example in FBD:
Example in ST:
VarSTRING1 := MID ('SUSI',2,2);
Note!
String functions are not "thread safe": When using tasks, string functions may only
be used in a single task. If the same function is used in different tasks, there is a
danger of overwriting.
CONCAT
Provided by standard.lib.
Concatenation (combination) of two strings.
The input variables STR1 and STR2 as well as the return value of the function are type
STRING.
Example in IL:
LD 'SUSI'
CONCAT 'WILLI'
ST VarSTRING1 (* Result is 'SUSIWILLI' *)
