Using the local HMI or Web HMI for monitoring
•
Select

to monitor measured and calculated
values.

Available measured and calculated values depend on measurement functions
which are included in the application configuration.
On the LHMI, the selected submenu can be scrolled with

.
WHMI supports the phasor diagrams that can be found under the measurement node
in the navigation tree. Phasor diagrams are based on values that can be found under
Fundamental frequency based values.

1.
Start Signal Monitoring tool when connected to the IED.
2.
Select the measuring function to be monitored.
Monitored values can also be exported as an Excel worksheet.
