SCB3000 dynamic IP address connection: SCB3000 is set to dynamic IP mode by default, and the network connection is simply made by connecting the SCB3000 NET port to the router LAN port with the network cable, which is plug and play. To configure the SCB3000, connect your computer to the router with a network cable, and launch the ProMate software in which you can click "Scan" to complete the connection successfully. When the configuration is complete, disconnect the computer from the router. Note: If the SCB3000 is set to static IP mode, you need to switch to dynamic IP mode before you can configure it using dynamic IP connection. Press and hold the "RELOAD" button for about 4 seconds, this will make the LED signal indicators flash from right to left, indicating a completed reset and restart, after which the SCB3000 will be switched to static IP mode. 12 2. SCB3000 static IP address connection: Note: SCB3000 is set to dynamic IP mode by default, you need to switch the SCB3000 to static IP mode first by pressing and holding the "RELOAD" button for about 10 seconds, this will make the LED signal indicators of the SCB3000 flash from right to left, indicating a completed reset and restart, after which the SCB3000 will be switched to static IP mode (the default IP address is 192.168.1.200). The user needs to set the computer to static IP mode, and configure the computer's IP address and the SCB3000's IP address in the same network segment. The steps are as follows (using Windows 7 OS as an example). Users can find the methods on the Internet that can be used to modify the IP addresses of computers running different operating systems. (a) Use a network cable to connect the "NET" of the SCB3000 to the Computer's Ethernet port. (b) Right-click"Network" and select "Properties". (d) In the local connection popup dialog box, right-click "Local connection" and click "Properties". (c) Click "Change adapter settings". The following popup dialog box is displayed: 13 14 (e) Double-click "Internet Protocol Version 4 (TCP/IPv4)" to show the "Internet Protocol Version 4 (TCP/IPv4)" popup dialog box, and set up the dialog box according to the requirements below. The default IP address of the SCB3000 is 192.168.1.200. To keep the computer and SCB3000 in the same network segment, the "IP address" and "Default Gateway" should be set at the 192.168.1.XXX segment (1XXX250XXX200). For example: The IP address can be set to 192.168.1.100 and the default gateway 192.168.1.254. 5.2.2 Parameter Configurations (for PLC communication with the inverter) When the connection to ProMate is successful, parameter configurations can be made on the SCB3000 and the inverter to which it is connected. (a) Choose Protocol Click the "Ezlogger Pro" button and select the protocol in the following popup. Custom is used for parameter configuration and Modbus protocol for normal communication. The machine is set to "Custom" in the factory by default, and the following protocol showed in grey is the one that is currently used. After switching protocols, ProMate waits about 1 minute to proceed. Click the "Connect" button in ProMate, when it shows that the connection is successful, ProMate is connected to the SCB3000 successfully. Note: Select the GOODWE custom protocol first to configure the BOX No and inverter address, then switch to the Modbus protocol for communications after all parameters have been configured. Note: If there is only one Box-type substation on the customer site, and the data is uploaded to GOODWE servers, there is no need to configure the box number and address through ProMate, simply connect ProMate, click to get the inverter list to see if the inverter is all online. If there are multiple box Box-type substations onsite, refer to 5.2.2 for setup. 15 16 (b) Settings of Device Count and Box No Enter numbers for both "Device Count" and "Box No". For "Device Count", enter the number of inverters actually connected to the current SCB3000. The "Box No" is used to identify the Box-type substations onsite. (For example, if there are multiple SCB3000s in use onsite, they must be corresponding to different box numbers) As shown below: the number of inverters connected to the SCB3000 on-site is 3, so the "Device Count" of 3 in entered. (c) Inverter Address Configuration Connecting the SCB3000 to the inverter requires the Modbus address to be configured, with the option of one click and manual operation available for the inverter address configuration. As shown below: Click the "One key config" button, and the software randomly assigns the inverter address. Note: The Device Count and Box No are required, the devices will not function properly if either field is not filled in. As shown below: When finished setting the Device Count and the Box No, you can click the "Read" button to see if the settings are successful. As shown below: Click the "Set" button to see if the configuration is successful. 17 18 (d) Manually configure the inverter address As shown below: If there are special requirements for the inverter address on the customer site, you can choose to manually add the Modbus address by clicking "Add", entering the inverter serial number, box number, and the corresponding Modbus address in the following popup box, selecting "OK", and then clicking "Manual config" to add the address. As shown below: Click the "Update" button, enter the parameters to be modified in the popup dialog box, click "OK" and then click "Manual config". As shown below: If you need to modify the Modbus address after adding it, you can select the inverter serial number that needs to be modified, click the "Update" button, enter the parameters to be modified in the popup dialog box, click "OK" and then click "Manual config". (e) Protocol Switching As shown below: In the inverter list section at the right side, click "Refresh" to show the SCB3000 connected inverters' status, confirm that all inverters are online. After the Modbus address has been configured, you can return to the "EzLogger Pro" interface where the Modbus protocol is selected in the protocol selection. Note: After selecting "Add", "Update" or "Delete" in the manual configuration section, you must click the "Manual config" button to make it become effective. 19 Note: 1. Please confirm the inverter Box No and SCB3000 Box No are set to the same value. If this is not the case, after switching to Modbus protocol, the SCB3000 will not be able to communicate with the inverter. 2. It takes about 1 minute to complete the protocol switching. After the switching is successful, wait for all the inverters to go online and the SCB3000 communicates properly with the inverters. 20 5.2.3 RS485 Port Configuration If it is required to apply the three RS485 ports COM1, COM2 and COM3 to connect the inverters on the customer site, you can use the port configuration to pre-set the number of inverters. For example, if you set the number of inverters connected to the COM1 and COM2 ports to 10 and 13 respectively, then check COM1 and COM2, enter the numbers 10 and 13, click "Set" to complete the setting. 5.3 Configuration Instructions for Fiber Optic Switches Refer to these instructions if you choose the fiber optic version.
