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 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.

Principles of Operation The CON-MBUS allows you to collect multiple types of data from M-Bus meters wired to an Delta installation. The CON-MBUS Solution consists of the following components: Delta enteliBUS, DSC or DAC controller • Custom Delta Gateway object and Gateway Translation objects residing in the Delta •...
LED function. Power over M-Bus Network The CON-MBUS can supply power to meters over the M-Bus network. The CON-MBUS can power up to 150 meters that each use 1 unit load of power. A unit load is equivalent to 1.5 mA.
Each step is detailed in sections titled Step1 ..., Step 2... and so on. If you choose to download GWT objects from the CON-MBUS page on the George site, then you would follow the first four steps and then Step 6. These GWT objects are already configured for a specific product from a manufacturer.
In Version 3.40, you need to install both the customized Gateway (GW) object and the Gateway Translation (GWT) object dialogs. Download the customized dialogs as POB files from the CON-MBUS support page on the George support site. After the required customized dialog(s) has been downloaded and saved as described in following sections, restart the OWS for the changes to take effect.
Step 3: Connecting and Configuring the CON-MBUS The CON-MBUS is wired to a Delta controller via RS-485 cabling. See the CON-MBUS Installation Guide on George for more information about this connection. The two objects used to configure the M-Bus interface are the Gateway (GW) object and the Gateway Translation (GWT) object.
1. From ORCAview, open the CON-MBUS Interface (GW1) object and select the Setup tab. In the Port Settings section, set Port to the one that the CON-MBUS is connected to. The default is NET2. Reset the device after saving the GW1 settings if you choose to use NET1.
Use a third party optical interface with software to get the meter information. • With one meter connected to the CON-MBUS, enter a meter number and check for • communication. Check the Description tab of the GWT objects for information such as the Meter ID#.

GWT object. To confirm that the meter is transmitting, observe the LEDs in the CON-MBUS and also the M-Bus meter. The presence of information in the Description tab of the GWT confirms that the meter is communicating.
GWT object, described below as method A and method B: A. Obtain the GWT object from the CON-MBUS page on George and load it into the Delta controller. Using GWT objects from this George page is the recommended approach.
The Setword6 property allows you to set a retry timeout for querying meters. Adding wait time before a query allows for slower meters, for example, some Apator meters. The CON-MBUS sends the query to the meter three times but some meters need more time to respond.
Recommended method: (easy way) Following Step 4: since you obtained the GWT • object for this meter from the CON-MBUS page on George, the GWT object is ready- to-use and is configured to translate the meter data. All you need to do is to click the Create BACnet Objects button to map the data.
How to Integrate the CON-MBUS Creating the BACnet objects 1. Open the GWT object dialog. 2. Enter the object instance in each row of the Reference column. For AV or BV objects, enter AV20 or BV20 for example. See Tables of Supported BACnet Objects and Addressing Schemes for more information.

The value from the meter could be KwH, but if it increases beyond an upper range then the meter might internally change to MwH and this is very difficult, if not impossible to handle in a program on a controller. CON-MBUS Application Guide Page 23 of 48 Document Edition 1.4...
Example 1 assumes that you use an existing GWT1 object as a template. You could download something similar to this from the CON-MBUS product page on George. Example 2 assumes that you create and configure a new GWT, rather than download an existing GWT from the George support site.

How to Integrate the CON-MBUS To configure an existing GWT object for the Sontex Supercal 531: 1. Open the existing GWT1 object dialog. This dialog can serve as a template for the Sontex 531 meter. 2. Starting in the second row of the Reference column, enter an object instance, such as AV1 to replace the asterisk * character.

How to Integrate the CON-MBUS BACnet Objects: Naming Scheme for Objects When the BACnet objects are created on the controller, they employ a naming and an instance numbering scheme. The full name consists of the GWT object name, an underscore, and the name in the Name column.
For OWS 3.40 R1, manually assign the object numbers for the inputs. You can assign up to 250 objects and distribute them as required. On a controller, you can assign ten inputs for a GWT and then just one input for another GWT. CON-MBUS Application Guide Page 35 of 48 Document Edition 1.4...
