5.2 Master Computer Operations & Parameter Configurations
Promate is a software released by us for the configuration of the SCB3000 functions, it enables the modification of the network IP address of the SCB3000, the configuration of
the number of port-connected inverters, time settings, RCR and DRED features configuration, field debugging, and more.

5.2.1 Connecting to the Master Computer Software
If the user wants to configure the SCB3000 using ProMate software, the master computer needs to be connected in either dynamic IP (DHCP) or static IP according to the way the network is connected.

1. 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 a 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.

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”.

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 192.168.1.XXX segment (1≤XXX≤250且XXX≠200).
For example, The IP address can be set to 192.168.1.100 and the default gateway 192.168.1.254.

Click the “Connect” button in ProMate, when it shows that the connection is successful, ProMate is connected to the SCB3000 successfully.

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.

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.
