Name
Displays the actual value at the digital input terminals on the CU. This parameter shows the actual value,
uninfluenced by simulation mode of the digital inputs.
Status of digital inputs (CU)
r0722
Displays the status of the digital inputs on the CU. This parameter shows the status of the digital inputs
under the influence of simulation mode of the digital inputs.
Status of digital outputs (CU)
r0747
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.
Profibus status
r2054
Displays the status of the Profibus interface.
System load
r9976[0..7]
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.

of the infeed voltage.
DC link voltage smoothed
r0026
Displays the smoothed actual value of the DC link.
Absolute actual current, smoothed
r0027
Displays the smoothed actual value of the current.
Power Module temperatures
r0037
Displays the measured temperatures in the Power Module.
Missing enable signals
r0046
Displays missing enable signals that are preventing the closed-loop infeed control from being commissioned.
Active command data set (CDS):
r0050
Displays the effective command data set (CDS)
Rated power module power
r0206
Displays the rated power module power for various load duty cycles.
Rated power module current
r0207
Displays the rated power module power for various load duty cycles.
Rated power module line supply voltage
r0208
Displays the rated line supply voltage of the Power Module.
