1 Description
1.1 Capabilities
The Messenger W is a highly configurable platform for remote monitoring and control applications. Some of
the capabilities are listed below.
• Local computations from monitored conditions
• Time stamping of monitored data and events
• Battery-backed historical data/event buffers
• Automatic monitoring of max/min for analog values
• Event and data logging
• Telemetry of monitored conditions to host server-based applications via cellular
• Over-The-Air (OTA) programming and diagnostics
• SMS messages sent on monitored conditions
• Parameter setting via SMS messages
• Rate of change alarm/flow totalization on physical analog input channel
• Pulse counter on all physical digital input channels
• High/low warning/alarm on all analog channels
• Daily count and duration alarm on all physical digital input channels
1.2 Monitoring
All monitored values can be transmitted via cellular to a host server of the customer’s choosing. Monitored
values are transmitted based on time or notification events. Notification events are based on rules set by the
user and each event can generate an immediate report. Telemetry includes cellular data connectivity to host
server or SMS messaging direct to user.
Monitored data values are mapped to fixed channels in the Messenger W. A channel defines a set of attributes
for the monitored data for doing calculations, alarm detection, data formatting and reporting.
For example, the physical analog input is fixed to channel 62. For channel 62, the user can set high/low limits
to generate notifications to a host server or directly to the user via SMS.
A description of all the predefined channel numbers can be found in the Defined Channels section.
1.3 Host Server Communications
The Messenger W utilizes a proprietary protocol to send notifications and to receive OTA commands from a host
server. Each notification sent typically consists of location, date/time, an event code and associated data. An
event code provides a unique identifier to indicate the reason that the notification is being sent – for example,
normal scheduled update or an alarm detection event. A description of the protocol, format of messages and
definition of event codes is available on request (document number “M09-PRTCLxxx”).

User Manual

9M02-7000-A001-EN
Version A
Some of the conditions on which notifications can be sent to the host server are listed below:
• Any monitored value exceeding a predefined or user-defined limit
• A digital input changing state (on/off)
• A digital output changing state
• An analog input transitioning into a warning or alarm region
• A scheduled update
• System faults
• SMS text commands from a user or host server
• Power on or reset
1.3.1 Event Codes
Every message sent by the Messenger W to a host-based server application is triggered by an event. The event
generates a message and the message contains an Event Code. The Event Code uniquely identifies to the
server the reason the message is being sent. Some of the messages generated contain data; others serve
simply as notification that a particular event has occurred.
1.3.2 Store and Forward Data Queue
There are several scenarios where a message may not be deliverable – network down, host server down
and poor connectivity, to name a few. In the event that a message cannot be delivered, it is stored in
memory and is continually re-sent until it is properly acknowledged. This store and forward memory is non-
volatile and remains intact during power off.

2 Installation and Setup
This section provides information on installing the Messenger W and confirming its initial operation.
WARNING
IT IS RECOMMENDED THAT YOU READ THIS ENTIRE SECTION BEFORE STARTING THE
INSTALLATION.
2.1 Installation Steps
Installation consists of the following steps:
1. Unpack the Equipment.
2. Mount the Equipment.
The Messenger W should be mounted in a vertical position to try and minimize the chance of water
entering through the antenna connection. The antenna wire should have a service loop just below the
antenna connector.
3. Connect Main Power.
4. Connect Field Signals (digital, analog, Modbus) to the appropriate wire. Wiring information can be found
in Figure 2and Figure 3in the Diagrams section.
2.2 Unpacking the Equipment
The Messenger W is shipped with the following:
• The Messenger W electronics in a Deutsch thermoplastic enclosure or a board-only product
• A Cellular antenna (magnetic mount or bulkhead)
• User Manual
• Optionally, a cable harness
2.3 Mounting the Equipment
The Messenger W is available in an automotive grade weather resistant enclosure; the dimensions of the
enclosure are shown in Figure 1.
CAUTION
MOUNT THE MESSENGER W VERTICALLY AND PROVIDE A SERVICE LOOP FOR THE
ANTENNA CABLE TO PREVENT WATER INTRUSION.

2.4 Mounting the Antenna
The antenna shipped with the Messenger W is a cellular hockey puck style. The antenna can be ordered with a
magnetic or a screw mount base.
In general, the antenna should be mounted with an unobstructed view of the sky. If the antenna is mounted
outside and may be subject to lightning, a surge arrestor can be inserted between the antenna and the
Messenger W. If the antenna is mounted inside, it should be located near a window.
CAUTION
SERVICE LOOPS SHOULD BE PROVIDED FOR THE ANTENNA CABLING, NEAR THE ANTENNA
CONNECTION, TO MINIMIZE WATER INGRESS THROUGH THE CONNECTION.

3 LED States
There are eight LEDs used to indicate various system conditions. The locations of these LEDs can be seen in
Figure 2in the Diagrams section. Specific information is conveyed to the user via LED blink patterns. On power-
up, an LED test is performed by blinking all LEDs every second for 3 seconds. Following the LED test, the LEDs
blink based on the following conditions.

4 Channels
The Messenger W maps all monitored conditions into channels. Each channel has data storage and configuration
parameters. Data storage holds current value, max/min values, and other run time data values.
Every channel in the Messenger W is referenced by a fixed channel number; for example, the analog input
channel is always channel 62. There is a set of predefined channels (numbers 1-300) and a set of Modbus
channels (numbers 301-380). The Modbus channels are user configurable for reading/writing digital or analog
values from a Modbus RTU slave device.
4.1 Defined Channels
The following channels are predefined in the Messenger W. The wiring for some of these channels can be found
in Figure 2and Figure 3in the Diagrams section.

4.2 Channel Data
All values read from physical IO or from a Modbus slave device are continually updated and tested as defined by
the configuration parameters. For each channel, based on its type (analog or digital), there is a basic set of data
collected. For purposes of discussion, the term “not normal” is used to indicate an analog value that has violated a
limit threshold or a digital value that does not match its configured ‘normal’ state.
Basic Data Set –
For the analog channel:
• Current value
• Max/min values (daily and trip)

Messenger W
User Manual
13
9M02-7000-A001-EN
Version A
For the digital channels:
• Current value
• Previous value
• Count of transitions to not normal (counts)
• Accumulated time in not normal state (duration)
There are a few channels that can be configured for special functions. All the physical digital input channels can
accept pulse inputs (e.g., from a flow meter) and the physical analog input can be used to totalize volume when
the input is flow rate. These channels have an extended data set.
Extended Data Set –
For the analog channel:
• Daily total volume (available on separate channel, 154)
• Continuous running total volume (available on separate channel, 155)
For the digital channels:
• Flow rate
• Daily total volume
• Continuous running total volume
The Messenger W also maintains a set of daily data.
The daily data set is a separate set of current and max/min values that span the 24 hour period from midnight to
midnight, UTC time. At midnight, an end of day report is generated from this data.
Because Modbus channel data is polled, Modbus digital channels do not maintain count or duration values.
