Summary:
Strings which are not NULL terminated in the PLC will show extra junk characters when displayed in Citect. Citect uses the NULL character to check for the end of a string, and if no NULL character is present, Citect will read (and display) any junk characters in memory - after the end of the string. 

Solution:
All strings must be NULL terminated in the PLC.
