Identification of the communications components
The read-only parameter r2053 shows the information by which the various firmware
components of the PROFIBUS-DP interface can be identified.

Standard diagnostics
When the parameter P2041.03 = 0, then by using the read-only parameter r2054 and it's
indices, it is possible to obtain detailed diagnostic information regarding the PROFIBUS-DP
interface. This information is listed in table below.
