Note
r2050 also acts as a display parameter through which the setpoints received by the
PROFIBUS DP interface can be checked.
P2041 PROFIBUS DP functions
A number of advanced property settings for the PROFIBUS DP interface can be
accomplished using the indexed parameter P2041.
For most applications, however, the defaults values are adequate (value = 0). The following
table shows the property setting options.

Parameter Meaning Value range
P2041.01 OP parameter in EEPROM:
Modifications to parameter settings
via SIMATIC HMI are stored
permanently in the EEPROM or as
volatile data in the RAM.
0: Permanent (EEPROM)
1: Volatile (RAM)
P2041.03 Select displayed diagnostics
screen.
0: Standard diagnostics
>0: Special diagnostics (for SIEMENS internal use
only)
Caution
The watchdog function should not be deactivated! If the monitoring function is deactivated
and the PROFIBUS DP interface fails, the inverter will not recognize a fault condition and
continue to operate even if a fault condition exists.
