4 Introduction
Purpose
This chapter provides an initial description of the CMe3100 Metering Gateway and how it can be applied
to different types of metering systems. In the next-coming sections you will get to know the product
features and how to combine the CMe3100 with other products to build versatile solutions.
Application description
4.2.1 Applications
The CMe3100 is, directly out of the box, a very powerful and versatile M-Bus Metering Gateway. It can be
extended in various ways using a flexible model for licence and add-on upgrades.
While there are many ways to utilize the potential in the CMe3100, its three core application areas are:
1. Quick and simple metering with integrated statistics
2. Metering and local integration with PLC/DCS
3. Full Gateway integration using e.g. DLMS or REST
Additionally, all features can be used in a mix to address application specific needs. It also fully supports
all types of utility meters that are M-Bus or Wireless M-Bus compliant.
4.2.2 Quick and simple metering with integrated statistics
For small applications with a low requirement for integration, the CMe3100 is very quickly setup using its
predefined readout schedules and metering reports (Push Reports). Once the meters have been
installed, the device can be configured to readout meter values at specific time intervals and compile
them in a suitable report format to be sent to a receiving system. If the need of integration is low, the
report can be as simple as an e-mail sent at a fixed schedule.
Thanks to the device’s built-in M-Bus decoder, meter values can be delivered in a human readable format
with correct precision and unit. With its user-friendly web interface, the device also serves as a complete
metering web service. Among various features, measurement series and calculated series, such as mean
value, can be displayed as illustrative graphs.
The built-in database, storing all meter values locally in the CMe3100, provides a solid base for its
system robustness. All Push Reports have an intelligent retry mechanisms that automatically schedules
retries for failed reports including all values for which previous transmissions have failed.

Version 1.3
4.2.3 Metering and local integration with PLC/DCS
For standard applications with a medium requirement for integration, the CMe3100 is very quickly setup
using its predefined readout schedules and metering reports (Push Reports). Once the meters have been
installed, the device can be configured to readout meter values at specific time intervals and compile
them in a suitable report format to be sent to a receiving system. Reports are transmitted using
standardized internet protocols, such as SMTP (e-mail), FTP or HTTP.
Thanks to the device’s built-in M-Bus decoder, meter values can be delivered in a human readable form
with correct precision and unit.
The built-in database, storing all meter values locally in the CMe3100, provides a solid base for its
system robustness. All Push Reports have intelligent retry mechanisms that automatically schedules
retries for failed reports including all values for which previous transmissions have failed.
The built-in database also enables excellent and reliable options for local integration with a Digital Control
System (DCS) or a Programmable Logic Controller (PLC). These types of system components are
usually found in real-estate systems to control for example heat and ventilation. Interfacing systems may
choose to connect using ModBus, M-Bus or JSON (TCP/IP) to retrieve meter values directly from the
CMe3100 without affecting its normal operation or having to communicate with the M-Bus meters directly.
If the CMe3100 is used in a mixed application with metering reports and high demand for real-time meter
values being supplied to a PLC or a DCS, there is an additional mode available, Continuous Readout
Mode. When activated, the CMe3100 reads all meters as frequent as possible and makes the readouts
available to interfacing systems but without affecting the reporting mechanism. This enables metering
reports to be configured independently from how the interfacing system’s meter value requirements.
Figure 2: Metering and local integration with DCS
4.2.4 Full Gateway integration using e.g. DLMS or REST
For demanding applications that requires a high level of vertical integration, the CMe3100 supports the
REST or DLMS protocols. Using these protocols, meter values and configuration settings are available
without having to bother about specific details of the M-Bus metering format. A head-end system may
access most current readouts, historical values as well as log information, Meter Lists and change
notifications.
The built-in database, storing all meter values locally in the CMe3100, provides a solid base for its
system robustness as historical meter can be recovered by the head-end system at any time.

Product features
The CMe3100 M-Bus Metering Gateway has the potential to read, convert and deliver meter values from
all types of M-Bus meters, regardless of manufacturer. This makes the device quick and easy to integrate
into an existing M-Bus system. The key features of the product include:
•An integrated M-Bus Master which can drive up to 32 unit loads (32T). By using an Elvaco M-
Bus Master it is possible to extend this number up to 256 unit loads.
•Customized meter value reports via HTTP, FTP and e-mail.
•A built-in web interface for easy configuring of settings.
•Remotely updatable software.
•Meter value integration via MODBUS, REST, JSON-RPC and DLMS.
A more extensive technical description of the Metering Gateway is provided in chapter 7 (Technical
specifications).
Compatibility and extensions
4.4.1 Licensing scheme
The CMe3100 is equipped with a flexible licensing scheme that allows its capabilities and features to be
enhanced through the addition of license files. This allows for both a cost-effective customization at the
purchase point as well as the possibility to later extend the product functionality without changing the
hardware.
Licenses are distributed as files, bound to a specific serial number. A license file may contain several
different types of licenses but an individual file is always required for each product.
There are two main categories of licenses available, performance and feature licenses.
The performance licenses determine, from a software perspective, how many meters that may be used
with the device. Licenses range from 8 to 256 meters in steps of, 8, 32, 64, 128 and 256.
Feature licenses enable new services in the product, for example integration protocols such as Modbus,
REST, JSON and DLMS.
To learn more about the different licenses available, please visit:
https://www.elvaco.se/en/product/infrastructure1/cme3100-m-bus-metering-gateway-for-fixed-network--
CMe3100.
A software update is not necessary when changing the licenses, the functionality is
already part of the software and just needs the correct license file to be unlocked.

Version 1.3
Without a license, the product is limited to 8 meters even though the integrated M-Bus
master can handle up to 32 unit loads.
4.4.2 Integration with other products
The CMe3100 can be used in combination with an M-Bus Master from Elvaco to increase the number of
slave devices it is able to drive (the device can by default drive up to 32 unit loads, where one load
equals 1.5 mA). It can also be combined with an Elvaco Wireless M-Bus Receiver to receive meter
reading from wireless meters using the Wireless M-Bus Protocol.
The CMe3100 is compatible with a wide range of meters, including:
•ABB electricity meters supporting communication via IR interface.
•All types of M-Bus meters, regardless of manufacturer.
•The following temperature and humidity sensors, manufactured by Elvaco: CMa10,
CMa10W, CMa11, CMa11W, CMa12W, CMa20, CMa20W.
4.4.3 Wired and Wireless M-Bus
The CMe3100 can be used together with Wired M-Bus meters, Wireless M-Bus meters or a combination
of both. The integrated M-Bus master can handle up to 32 unit loads so for smaller systems, the
CMe3100 may operate independently. For larger systems, the number of M-Bus devices the CMe3100 is
able to drive is easily extendable through any of Elvaco’s M-Bus Masters in combination with a licence
upgrade.
CMe3100 has a built-in system for wireless encryption key handling, and can easily be integrated in a
Wireless M-Bus metering system. In order to receive wireless meters, the CMe3100 needs to be
complemented with an Elvaco Wireless M-Bus Receiver.
All extension devices, Wireless Receivers and M-Bus Masters from Elvaco are equipped with IR interface
to enable communication without any cabling by simply stacking the devices together.
Elvaco offers box-build turnkey solutions, containing all necessary products preconfigured,
directly from factory.

Access the web interface
5.6.1 Log in on the web interface from a browser
The CMe3100 is configured through its web interface, which is easily reached via the local USB slave
port (10). Connect the included USB cable between a computer and the Metering Gateway. After
approximately 30 seconds, a new removable disk will be available on the computer. Open the folder on
the removable disk, run the file CMe3100-SETUP.EXE and follow the instructions.
When the installation has completed, the web browser will open along with a login page. If the browser
fails to do so, please enter the IP address for the device USB port manually. For software versions older
than 1.6.0, the IP address 192.168.100.1 is used. For software version 1.6.0 or later, use the IP address
169.254.254.1.
Login using the following credentials:
Username: admin
Password: admin
After logging in for the first time, a new password will have to be registered.
If the SETUP.EXE utility has already been run once on the computer, it will not have to be
run again. The utility has installed a driver that creates a virtual TCP/IP connection on the
computer which accesses the CMe3100 using the local IP address.

6 Operations guide
Basic operations
Purpose
This chapter provides instructions on how to use the web interface to configure the most basic settings of
the CMe3100. After executing each step of this chapter, the Metering Gateway will perform scheduled
readouts of its installed meters, and deliver customized reports with meter values. Please read through
each step carefully.
Use the installation panel to perform basic setup
When first logging in on the web interface, the Installation panel will be presented. From this page, all
parts of the basic setup process are easily accessible. To ensure correct operation of the product, time
and network settings should be configured first.
Set the time
Purpose
In order for the device to operate accurately, it is important to set the correct time and make sure that the
clock stays synchronized. This is done by synchronizing it with a time server at a fixed time interval and
selecting the maximum accepted time difference the device’s clock is allowed to have.
6.3.1 Configure time settings
To configure time settings:
•Go to Date & Time from the Basic setup window of the Installation panel. Enter the time and
select the time zone.
•Set the Time synchronizing schedule and the Maximum accepted time difference.
•Select whether to use a Daytime or a Network Time Protocol (NTP) server and enter the
address of the server. If using the NTP alternative, a server timeout value needs to be set. It
determines for how long the Metering Gateway will wait for the NTP server to respond during

a time synchronization attempt before interrupting the action.
•Click Save.
The time synchronizing schedule that should be used depends on how tightly clocks need
to be synchronized. Assuming that the maximum accepted time drift is in the order of one
minute per month, utilizing a schedule of every 12th hour should assure that the product
has less than one second’s time difference (31 days * 24 hours = 744 hours, 60 seconds /
744 hours * 12 hours = 0,97 seconds). The default value will work well in most cases and
allow for an ample timeout.
If the radio link between the product and the time server is of poor quality, the value might
have to be increased until reliable operation is obtained. It’s important to note that a poor
quality radio link will negatively affect the performance of the time synchronization as it
relies on low latency communication.
You may disable the use of time synchronization and manually enter time and date in the
product if the long term accuracy is not a concern. However, be aware of:
•The product has a built in super capacitor to maintain time and date during e.g. a
power outage but it will only last around 24 hours. After that the clock will no longer
be running and time will be offset accordingly.
•The built in clock will drift over time, theoretical worst case is around the order of
one minute per month but will most likely be smaller in practice and will vary due to
temperature, tolerances and age of components.
•If you are using multiple products for collecting meter values, it is very strongly
advised that you configure the products to use time synchronization to assure that
measurements from different sources are aligned with regards to time and date.

Configure network settings
Purpose
Configuring the basic network settings will enable the Metering Gateway to connect to the local network.
This is necessary to enable the Metering Gateway to connect to servers and deliver its collected meter
data.
6.4.1 Configure IP address settings
There are two types of IP address assignment options available, the static and the dynamic option. Using
a static IP address enables assignment of the IP address manually. It will thereafter stay constant over
time. By instead using dynamic IP addressing, an available IP address is automatically assigned to the
Metering Gateway through a DHCP server, which must be available on the local network.
It is highly recommended that you use dynamic IP-address assignment to avoid
mistakenly duplicated IP-addresses and make IP-address administration as easy as
possible. Please refer to your IT administrator for details and/or more information about
what network settings to use.
6.4.2 Change the hostname (optional)
The hostname setting determines which name the Metering Gateway will use to identify itself on the
network. If not changed, a default name based on the product name and serial number will be used, e.g.
“cme3100–0016002383”. The hostname is ONLY used for network addressing and should not be
confused with the product’s name, the latter is used to identify the product in e.g. Push Reports. For more
information about how to configure the device name used in Push Reports, see section 6.34 (Configure
identity settings)
To change the hostname of the device:
•Go to Network settings from the Basic setup window in the Installation panel.
•Enter the name that will be assigned the Metering Gateway.
•Click Save.
Your DHCP server must have enabled support for dynamic DNS update in order to
support resolution of the hostname to an IP-address. Please refer to your IT administrator
for details and/or more information about what features that are supported.
To configure the IP address settings:
•Go to Network settings from the Basic setup window in the Installation panel.
•Select whether to use static or dynamic IP address assignment. If selecting the static option,
enter IP-addresses and a netmask.
•Click Save.
