1 Description
1.1 Capabilities
The Messenger is a highly configurable platform for remote monitoring and control
applications. Some of the capabilities are listed below.
•
virtual real-time transfer of monitored conditions
•
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
•
OTA programming and diagnostics
1.2 Monitoring
All monitored values can be transmitted via cellular to the RemoteIQ cloud-based
server. Monitored values are transmitted based on time or events. Notification events
are based on rules set by the user and each event can generate an immediate report.
Telemetry includes cellular connectivity and GPS for asset location.
The Messenger 600 reads values using the Modbus RTU protocol over an RS485 serial
connection. The user programs each of the 600 values that are to be read into
Messenger channels, which are numbered from 301 to 900.
1.3 Host Server Communications
The Messenger utilizes a proprietary protocol to send notifications and to receive OTA
commands from the RemoteIQ 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 notification is being sent – e.g. normal
scheduled update or an engine diagnostic message received. A description of the
protocol, format of messages, and definition of event codes is available on request
(reference protocol document “M09-PRTCLxxx”).
Some of the conditions on which notifications can be sent to the host server are listed
below:
•
Any monitored value exceeding a pre-defined or user-defined limit
•
Any diagnostic message received from the engine bus
• A digital input changing state (on/off)
•
A digital output changing state
