Product Description
The CON-MBUS is a level converter used to bring data from M-Bus (Meter-Bus) products into a
BACnet controller. The CON-MBUS can be used with any Delta Controls product that has an
available MS/TP port. The CON-MBUS is capable of supplying power to the meters and can
support up to 150 meters.
The CON-MBUS brings the M-Bus protocol directly into DAC,DSC and enteliBUS controllers.
The mapped data from a meter comes in through a Gateway Translation (GWT) object. The
GWT object instance matches the meter address so that it is clear which meter is
communicating with the CON-MBUS. Required BACnet objects such as AV, BV, BI, AI objects
are automatically created when the data is mapped into the GWT object.
Application
The CON-MBUS brings M-Bus meters into a BACnet network. One CON-MBUS can
communicate with up to 150 M-Bus meters. The information from the meters can be
customized and mapped into BACnet objects through a gateway object and thus providing the
ability to view only specific information from the meters. The update time for the meters is
adjustable to suit a variety of installations
The M-Bus protocol was developed to fill the need for a system for the networking and remote
reading of utility meters. For example, the consumption of gas, water or electricity in the home
can be measured. M-Bus fulfills the special requirements of remotely powered or battery
driven systems, including consumer utility meters. When interrogated, the meters deliver the
collected data to a common master. At periodic intervals, a hand-held computer, or a control
system could read all the utility meters of a building.

About M-Bus
The M-Bus® (Meter Bus) allows remote reading of consumption meters such as gas, water,
heat or electricity meters. The M-Bus communicates over two wires and is a low-cost solution.
M-Bus is a European standard: EN 13757-2 physical and link layer, EN 13757-3 application
layer. The standard is defined on http://www.m-bus.com/
Terminology
M-Bus refers to the Meter-Bus protocol standard.
CON-MBUS refers to the level converter product manufactured by Delta Controls that allows
communication between a BACnet controller and M-Bus meters . We avoid using M-Bus or
MBUS to refer to the CON-MBUS.
Gateway refers to the software special interface that is flash loaded into the host
eBCON/DAC/DSC controller. The gateway is viewed as a purely software entity.
Meter ID# refers to the unique ID assigned to a meter by the manufacturer. With CON-MBUS
software, this information is displayed in the Description tab of the GW object. For example, a
Meter Id# might be 10510405
Primary Address refers to the network address assigned to the meter in the factory. The
meter documentation includes address information. A new meter from the factory generally
has a primary address of 0. Primary addresses are in the range of 1 – 250.
Secondary Address refers to the physical address assigned to the meter. It provides a way to
search for a meter even though they all have the same primary address. The primary address
can be changed if the meter supports secondary addressing. Delta Controls products do not
support secondary addressing.
CON-MBUS Product Models
The CON-MBUS is available in the several models that support different numbers of M-Bus
meters. For details, see the CON-MBUS catalog sheet found on the CON-MBUS product page
on George.

Cautions and Warnings
These controllers are electrostatic-sensitive devices. Proper ESD protection
(ground strap) should be used when installing this product so that damage to
the product does not occur. Equipment damage or loss of data may occur if
these procedures are not followed as specified.
Installations requiring CE conformance: All wiring for CE rated products must
use a separated extra low voltage (SELV) or protective extra low voltage (PELV)
transformer. Use safety-isolating transformers, (Class II transformer) per
EN61558. The transformer must be rated for 100% duty cycle.
