Diagnostics addresses occupy in the input address range 1 byte each for the IO controller,
the PN interface and the IO devices (header module at slot 0), and for each module without
user data within the device (power module of ET 200S, for example). You can use these
addresses, for example, to read module-specific diagnostics data records by calling SFB 52.
The diagnostic addresses are specified in your configuration. If you do not specify any
diagnostic addresses, STEP 7 assigns these DP diagnostic addresses in ascending order,
starting at the highest byte address.
