4.9 FILTER
Mode of operation
The filters are the central elements of the RMS. They make it it possible
to logically combine the results recorded at the inputs, and to supply
the result to the digital outputs or to generate various signals.
It is possible to configure a total of 12 filters (RMS Advanced 40) with
an identical structure. In this case, all inputs are available to each filter.
Depending on the type of input signal (measured value, status, filter
feedback), in principle there are three different function blocks for pro-
cessing the results.
The results of all the function blocks are combined via a common, logi-
cal OR element to form the filter result.
This filter result can then, depending on requirements, be used to gene-
rate alarm messages (SNMP Trap, LED Warning, Buzzer), to control
digital outputs, or for feedback to other filters.
