Flexible Communications Options
The EPM 9900P meter offers up to 6 simultaneous communication ports and multiple protocols to meet almost every need.
Hardware Features:
2 optional RS485 ports speaking Modbus and/or DNP 3.0
USB front panel port
ANSI optical front panel port
2 separately addressable Ethernet ports
Optional Fiber or RJ45 media on one Ethernet port
8 Built-in Digital High-speed Status Inputs:
Inputs automatically sense whether the circuit is externally wetted
If externally wetted, input up to 150 VDC is accepted
If internally wetted, the meter supplies the necessary voltage for the
control application
Industry-Leading DNP 3.0 Level 2 Plus – Complies with DNP Level 1 and Level 2 Certification Requirements:
Up to 136 measurements (64 Binary Inputs, 8 Binary Counters, 64 Analog Inputs) can be mapped to DNP static points
Up to 16 relays and 8 resets can be controlled through DNP
Report-by-exception processing (DNP Events) deadbands with unsolicited response for serial communication
250 available events, in four event types (Binary Input Change, Frozen Counter, Counter Change, and Analog Change)
Ethernet Communication Port Capabilities:
2 Ethernet ports provide multiple simultaneous communication
Each port has separate MAC address and IP address
Supports Modbus TCP/IP, DNP 3.0 and IEC 61850
GOOSE messaging protocol supported for IEC 61850
Up to 32 Modbus TCP/IP sockets per Ethernet port
Highly secure port control to disable unneeded services and ports
Email Function - SMTP email to client on alarm
Precise Time Synchronization - SNTP Time Sync protocol
File Transfer Protocol - High-speed file data transfer
VAUX Input:
Neutral to ground or aux voltage readings
Synchronizing schemes, for example, obtaining the frequency, magnitude, and phase angle on both sides of a switch or between generator and bus voltage
Secure Communications:
The EPM 9990P offers 9 levels of password security to protect the meter from unauthorized use. Each level can be configured to enable specific
capabilities, so that a Utility can control access to functions according to
the type of user. For example, one user level is able to create and change
TOU calendars, while a different user level is able to read TOU data, but not
change anything.
