The EnerVista UR Setup software groups the D90
primary functions. Each function has its own settings and each generates its own outputs
in the form of operands.
• Communications
• Protection
• Automation
• Digital fault recorder (DFR)
• Metering
• Equipment manager
• Self-tests
• Front panel interface (HMI)
It is often desirable for an output from an element within one function to be available to an
element within another function. For example, it can 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 to each function, as shown.
