8.4 Troubleshooting via the Control System
Diagnostics using diagnostic parameters
The following diagnostic parameters are set via a higher-level control system. This function
is provided by Control Units, which communicate via PROFINET or PROFIBUS.
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.

r2053.00
r2053.01
r2053.02
r2053.03
r2053.04
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 the table below.
