Signal supervision
Six signals can be selected to be supervised by this function. Whenever a supervised
signal exceeds or falls below predefined limits, a bit in
32.01 Supervision status is
activated, and a warning or fault generated.
For example, if user wants to monitor DC voltage and generate a warning/fault
message if it exceeds certain limit, he/she can select DC Voltage [7] in the parameter
32.07 Supervision 1 signal , set low/high limit in the parameter 32.09 / 32.10 and set
the action in the parameter 32.06 Supervision 1 action .
The supervised signal is low-pass filtered.
