  • Page 6: Sma Gateway Description

    CAS-2700-24 SMA Gateway Manual Page 6 of 62 SMA Gateway Description The SMA Gateway connects to a SMA Sunny Webbox via an Ethernet (TCP/IP) connection. The SMA Gateway can then be configured to poll for data values from a number of devices that are connected to the Webbox.

When you discover the gateway, objects and properties you will find appropriately named objects that report data from the SMA Devices. Because BACnet supports discovery, usually knowledge of the BACnet Device Instance Number does not need to be known in advance.

Each additional device added will be offset by 100. So the first device will have data starting with analog-input 1, the second device will have data starting at analog-input 101, the third device will have data starting at analog-input 201, etc.
