Using the Delete Function on M-Bus Devices

You can use the Delete function to delete an M-Bus device on the SmartServer. The Delete function
takes an <Item> element with an MBS_Device_Cfg type as its input. The <Item> element only needs
to include the device’s <UCPTname> property in the Delete Request as demonstrated in the following
code sample:

Request

<UCPTname>Net/M-Bus Channel/M-Bus Device 2</UCPTname>

</Item>

</iLonItem>
</Delete>

Response

<Item>

<UCPTname>Net/M-Bus Channel/M-Bus Device 2</UCPTname>

</Item>
</iLonItem>
</Delete>

M-Bus Virtual Functional Blocks

Before you can add data points to an M-Bus device, you need to use the Set function to create a Virtual
functional block under the M-Bus device. This virtual functional block is used to encapsulate the
M-Bus data points and enable the M-Bus driver to adhere to the network hierarchy naming convention.
The Set function takes an <Item> element with an MBS_Fb_Cfg type as its input, as shown in the
example below.

Request (add a virtual functional block to an M-Bus device)

<Set xmlns="http://wsdl.echelon.com/web_services_ns/ilon100/v4.0/message/">
<iLonItem>
<Item

xsi:type="MBS_Fb_Cfg">

<UCPTname>Net/M-Bus

Channel/M-Bus

Device/VirtFb</UCPTname>

</Item>
</iLonItem>
</Set>

Response

<Item>

<UCPTname>Net/M-Bus

Channel/M-Bus

Device/VirtFb</UCPTname>

</Item>

</iLonItem>
</SetResponse>

M-Bus Data Points

The following section describes how to use the List, Get, Set, and Delete functions on M-Bus data
points. For information on reading and writing values to M-Bus data points, see Chapter 4, Using the
SmartServer Data Server.
