A FlexElement is a universal comparator that can be used to monitor any analog actual value calculated by the relay or a
net difference of any two analog actual values of the same type. The effective operating signal could be treated as a signed
number or its absolute value could be used as per user's choice.
The element can be programmed to respond either to a signal level or to a rate-of-change (delta) over a pre-defined period
of time. The output operand is asserted when the operating signal is higher than a threshold or lower than a threshold as
per user's choice.
