The EnerVista UR Setup software groups the D90
primary functions. Each function has its own setting parameters and each generates its
own outputs in the form of operands.
• Protection.
• Automation.
• Metering.
• Communications.
• Digital fault recorder (DFR).
• Equipment manager.
• Front panel interface (HMI).
However, it is often desirable for an output from an element within one function can be
available to an element within another function. For instance, it may be useful for the
digital fault recorder to record the output operands of any protection element.
Consequently a fixed, predetermined set of operands is available as to each function as
shown below.
