The D90 contains an advanced sequence of events recorder with the capability to
record up to 8,000 events.
Event information can be accessed either through the front panel or the EnerVista
Launchpad software. The very high sampling rate and large amount of storage capacity

The D90 supports a fault report and associated fault location data. The fault report
stores data pertinent to an event that is triggered and provides the distance to the fault
location. A maximum of 15 records are stored in the nonvolatile memory providing a
comprehensive summary of events associated with a fault.
The transient recorder captures critical system data during a transient event. It is tailored
to capture shorter duration events, such as faults at high resolution. The transient recorder
can be programmed to sample at 256 samples per cycle. The D90
records in nonvolatile memory with up to one minute of storage capacity for all 16 analog
channels and 128 digital channels. The transient recorder incorporates integrated
triggering. Any monitored channel can be configured to trigger the recorder.
Longer-term events are monitored by disturbance recorders and include voltage sag,
swell, and overloading. Any configured analog or digital channel can trigger the
disturbance recorder. The D90

The D90 communications module is dedicated to processing the IEC 61850, DNP 3.0,
and IEC 60870-5-104 protocols. This module provides redundant Ethernet ports, each with
10/100Base-TX and 100Base-FX connectors.
Modbus RTU and DNP 3.0 are also available as default protocols through the RS485 port or
the CPU Ethernet ports (slot D).
