Replacing a module
The CP 342-5 (6GK7 342-5DA03-0XE0) is suitable as a replacement for the following
predecessor products:
●
CP 342-5 (6GK7 342-5DA00-0XE0)
● CP 342-5 (6GK7 342-5DA01-0XE0)
● CP 342-5 (6GK7 342-5DA02-0XE0)
The CP 342-5 (6GK7 342-5DF00-0XE0) is also functionally compatible with the named CPs,
however it uses an optical instead of the electrical PROFIBUS interface.
