1 Introduction

The Sensus Automation Remote Telemetry Module™ (RTM II) is a cost-effective communication solution
for remote monitoring and control of Intelligent Electronic Devices (IEDs) that control electric distribution
system assets such as reclosers, switches, capacitor banks, breakers, voltage regulators, and meters.
RTM II devices can be remotely configured, monitored, and controlled through the secure Sensus
AutomationControl™ Web application using any standard PC. The RTM II includes serial connections, a
USB configuration port, and easy profile management through the AutomationControl software. The
RTM II communicates using the Sensus FlexNet® pr

The multi-address RTM II communicates with any IED that supports DNP3 or Modbus protocols. Models
with FlexNet rad
devices can be installed on any FlexNet system using the latest Automation Network Interface software.
FlexNet models incorporate all of the standard FlexNet system security features.

ios communicate using packet data over the Sensus FlexNet private networks. The

ivate networks.

The devices are ideally suited for Smart Grid distributio
capacitor banks, distribution switches, faulted circuit indicators, voltage regulators, distributed
generation, load control, and small substations.

1.1 RTM II Overview

The RTM II uses the radio network to enable communications between IEDs with supported protocols
and Sensus AutomationControl™. When it receives data from the RTM II, AutomationControl displays
the data immediately. Alternatively, the customer can use Sensus Automation’s DNP SCADA-Xchange™
software, which uses a secure TCP/IP connection to transfer the DNP3 data directly to the utility's
SCADA system.

Most newer generation Remote Termina

l Units (RTUs) and IEDs use the standard DNP3 communication
protocol to communicate with utility SCADA systems. The RTM II also provides a Modbus interface to the
many IEDs and RTUs that support this protocol.

The RTM II connects to an IED such as a recloser, voltag

e regulator, or capacitor bank controller through
an RS-232 serial port or an optional RS-485 serial port. The RTM II can either be installed as a
communications board within the IED enclosure or externally in its own weatherproof enclosure.

Solid Green Successful power on (power on call was received), the

Signal to Noise Ratio (SNR) is greater than 15.

Blinking Green SNR is between 7 and 14.

Off SNR is less than 6 or there is no communication from

AutomationControl.

Blinking Green The RTM II is functioning normally.

1.2 How it Works

The RTM II is programmed with a profile detailing the relevant points on the IED as well as how the user
wants the data to be reported. The RTM II accepts DNP unsolicited report-by-exception as well as
constantly polling the IED to get the latest data. When it discovers a reportable event, for example a
binary input that has changed state, it initiates a report over the radio network to AutomationControl.
Here, the data is validated and processed for distribution to the end user. In addition, control and
configuration information can be sent from the end user back to the RTM II.
