CONFIGURATION 6.1 NETWORK CONFIGURATION By default, the IP address of the KNX gateway is set to 192.168.1.51 Using a laptop connected to the gateway, open a web browser and navigate to the IP address of the gateway. Set a fixed IP address of your choice for the KNX gateway and configure the modbus TCP settings as below: Mode : Connect IP : IP Address of the inverter Server Port : 502 Uni Id : 126 (See note below) NOTE : SMA Inverter Unit ID must be set to 3 on the inverter to be accessible using Unit id 126 on the gateway ! There is an offset of +123 from the ID set on the inverter. © ELAUSYS SPRL This document cannot be reproduced fully or partially without written authorization User Manual Doc.Ref : INV-KNX-SMA-UM KNX Gateway for SMA Inverters Revision : Page : 2.01 14 of 17 6.2 KNX PHYSICAL DEVICE ELAUSYS devices are configured using the ETS tool. You should first download and install the free version of ETS tool before you continue. The INV-KNX Interface must be assigned a physical address on the KNX network. Assign a free address to the module, in our example we choose 1.1.2. 6.3 ETS PARAMETERS Once a KNX physical address is set, open the parameter tab to configure the interface. Select the type of AC network (single phase or tri-phase). Set the inverter model to 1 for SMA inverters Choose the refresh rate (min) for the complete set of data. Choose if battery 1 is available on the inverter. Device options should remain empty. © ELAUSYS SPRL This document cannot be reproduced fully or partially without written authorization User Manual Doc.Ref : INV-KNX-SMA-UM KNX Gateway for SMA Inverters Revision : Page : 2.01 15 of 17 6.4 ETS GROUP OBJECTS A group address (GA) must be assigned to each group object (GO) needed by the application. Open the Group Objects tab of the device and assign a GA to the objects as needed. When GO and parameters are all configured, download the KNX Interface application to the device. The first download requires to press the programming button on the device to set the device in KNX programming mode then perform a full download. © ELAUSYS SPRL This document cannot be reproduced fully or partially without written authorization User Manual KNX Gateway for SMA Inverters Doc.Ref : INV-KNX-SMA-UM Revision : Page : 2.01 16 of 17 6.5 INVERTER CONFIGURATION 1.
