Settings and Measured Values
8.2.1
“I/O Module” Tab
On the “I/O Module” tab, you can configure all 3 general settings, delete
minimum/maximum values and configure the energy measurements. These
settings apply to the entire I/O module.
Click the “Save” button to apply the value settings.
•
For “General,” select the network topology of the power supply network
from the list field. Select the phase for which the peak values are to be
specified as well.
In addition, you can disable the watchdog. The watchdog is enabled by
default and trips if no process data is received within 100 ms. The tripping
is signaled by the deactivation of the green “A” status LED. If the watchdog
is disabled, the green LED remains lit.
•
For “Min./Max. Values,” you can reset a specific minimum or maximum
value by selecting this value from the list field and clicking [
Delete
]. This
action is performed immediately.
•
For “Energy,” select the desired scaling factor from the list field. The energy
values are transferred to the process data with the configured scaling. If
necessary, reducing the scaling can prevent a process value overflow.
Enter the interval for cyclic energy consumption storage in seconds in the
text field.
•
Finally, you can specify thresholds for the energy measurements (active
power, reactive power and apparent power). This allows you to keep
creepage currents that are inherent to the system from affecting the energy
measurement. The energy measurement is interrupted immediately if an
underrun of one of the set values occurs.
See also section “Appendix” > “Parameter Assignment.”
The scaling factor can lead to rounding of the measured energy values in
the process image
The higher the energy value scaling factor is set, the more likely it is for rounding
to occur, and thus for the measured energy values in the process image to
deviate.
With counters for total energy (e.g., “Active energy, total” or “Reactive energy,
inductive, total”), the rounding of the individual energy values accumulates, which
may also lead to greater deviations.
Use the smallest possible scaling for your application in order to output
measured energy values in the process image that are as accurate as possible.
