Parameter Name
Description
r0747 CU, digital outputs status
Display of the CU digital output status. This parameter shows the status of the digital inputs under the
influence of simulation mode of the digital inputs.
r2054 PROFIBUS status
Displays the status of the Profibus interface.
r8937 PN diagnostics
Display to diagnose the cyclic PROFINET connections.
r9976[0..7] System utilization
Displays the system load.
The individual values (computation load and cyclic load) are measured over short time slices; from these
values, the maximum, the minimum and the average value are generated and displayed in the appropriate
indices. Further, the degree of memory utilization of the data and program memory is displayed.
Supply: Key diagnostic parameters (details in List Manual)
Parameter Name
Description
r0002 Infeed operating display
The value provides information about the current operating status and the conditions necessary to reach the
next status.
r0024 CO: Line frequency smoothed
Displays the smoothed line supply frequency.
r0025 CO: Infeed input voltage, smoothed

of the infeed voltage.
r0026 CO: DC link voltage smoothed
Displays the smoothed actual value of the DC link.
r0027 CO: Absolute actual current, smoothed
Displays the smoothed actual value of the current.
r0037 CO: Power unit temperatures
Displays the measured temperatures in the power unit.
r0046 CO/BO: Missing enable signals
Displays missing enable signals that are preventing the closed-loop infeed control from being commissioned.
r0050 CO/BO: Command Data Set CDS effective
Displays the effective command data set (CDS)
r0066 CO: Line frequency
Displays the line frequency.
r0070 CO: Actual DC link voltage
Displays the actual measured value of the DC link voltage.
r0072 CO: Input voltage
Displays the actual input voltage of the power unit (Line Module).
