Create a new device | To create a new device, go to [Tools] → [I/O Devices] or click the  I/O Device Name: Give a device name. This name will be used in the Tag tag configuration window of the database accompanied by the ‘Station Name’. |
Select a device type | After selecting the [OK] button on the previous step, the ‘Serial Communication Configuration’ dialog box will pop up.  Select ‘HITACHI Inverter’ in the ‘Device Type’ dropdown menu and configure the proper serial communication parameters. Ensure that those parameters are matched with the inverter's configuration. See the Communication Configuration section for more information. |
Create a station | Move to the [Station] tab of the ‘Serial Communication Configuration’ dialog box. Here, all the connected inverter stations can be configured and registered to the Xpanel.  Station Name: Give a name to the inverter. This name will be used in the database window accompanied by the Device Name. Station Type: Choose the type of connected inverter. Two inverter models are supported by this communication driver (SJ300 and L300P). Network ID: This field has no effect. Station No.: Specify a number between 1 and 32. This number must be matched with the number in the parameter of the inverter (Function Code: C072). 16bit Data Swap: This field has no effect. 32bit Data Swap: This field has no effect. Using Checksum: This field has no effect. This communication driver always checks the box. Comm. Error Message Pop Up: When this item is checked, Xpanel displays a communication error message box for every Rx and Tx error. Otherwise (unchecked), Xpanel does not display a message for communication errors. This message box will close automatically after a few seconds. See the Communication Configuration section for more information about the remaining parameters. |
