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.
