CON-MBUS Meter-Bus

The CON-MBUS Meter-Bus solution integrates Meter-Bus (M-Bus) devices into the Delta Controls building automation system. One CON-MBUS communicates with up to 150 M-Bus devices. The information from the meters can be customized and mapped into BACnet objects through a gateway object. This provides the ability to view specific information only 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. This 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.

Solution Components
The CON-MBUS solution consists of the following components:

• Delta enteliBUS (eBCON), DSC or DAC controller
• Custom Delta Gateway object and Gateway Translation objects residing in the Delta controller
• CON-MBUS converter handles M-Bus wired communication
• Up to 150 M-Bus devices

The Delta Controller and objects translate data passed through the CON-MBUS from the wired M-Bus devices. The data is represented as BACnet objects in the BACnet network.
