What is Automatic Meter Reading (AMR)?
Automatic Meter Reading (also known as AMR) is a data collection module of E-Mon Energy™ that can be
programmed to automatically receive incoming calls and/or initiate outgoing calls to the local and/or remote devices.
With AMR, you can constantly monitor your meters by setting up a pre-determined schedule based on frequency
and time.
The AMR application runs the schedule based on your pre-determined configurations and communicates using any
basic phone line (i.e. modem). Creating this type of environment allows you to maximize data collection around the
clock and/or during off-peak hours. Once the schedule is set, the scheduler works by itself, and does not require an
operator.
This section covers how an AMR schedule works, how to create an AMR (Call-In and Call-Out) schedule, and
running/maintaining an AMR schedule.
AMR components include:
• Schedule – Configure the call-in/out frequency and time – hourly, daily, weekly, or monthly.
• Task – Assign various functions for E-Mon Energy to perform once the connection is established.
• Server – Configure the telephone or IP Address number for the recorder to use for calling in.
How does the AMR Schedule Work?
The AMR schedule is created through E-Mon Energy. For AMR Call-in, the schedule is sent to the primary recorder
(Device ID 1A). For AMR call-out, the schedule is placed in the AMR Scheduled Task window, which is normally
minimized. When E-Mon Energy receives a call and the connection is established, it will first query the Group and
Location from the primary recorder. Once received, E-Mon Energy will look in the database for the record. If not
found, it prompts the user to add the unknown device into the system. If the record is found, E-Mon Energy looks up
the Task that’s been programmed, and performs the various functions automatically. When completed, E-Mon
Energy will logoff and issue the “Goodbye” command set to the recorder. See the illustration below.
