   APN user password

   • Method 2: When the SmartLogger connects to the management system over a wired network, set the wired network parameters and click Submit.
   Figure 6-29 Setting wired network parameters
   

   Parameter	Description
   WAN/LAN port working mode	Three working modes are supported: WAN+LAN, LAN+LAN, and WAN+WAN. If WAN+LAN is selected, the functions and IP addresses of the SmartLogger WAN and LAN ports remain unchanged. If LAN+LAN is selected, the SmartLogger WAN and LAN ports function as LAN ports, and the SmartLogger WAN and LAN ports share a LAN IP address. If WAN+WAN is selected, the SmartLogger WAN and LAN ports function as WAN ports, and the SmartLogger WAN and LAN ports share a WAN IP address. NOTICE: When the working mode of the WAN/LAN port is switched, the web page may be interrupted or the SmartModule may be powered off.
   DHCP	The WAN port of the SmartLogger supports IP address obtaining using DHCP and automatic registration. NOTE: After the SmartLogger connects to the SUN2000 app or FusionSolar app, tap More > Settings > Comm. Param. > Ethernet to access the Ethernet parameter setting screen and set DHCP to Enable.
   IP Address	Set this parameter based on the plant plan. NOTE: If the IP address is changed, use the new IP address to log in again.
   Subnet mask	Set this parameter based on the actual subnet mask of the LAN where the SmartLogger is located.
   Default gateway	Set this parameter based on the actual gateway of the LAN where the SmartLogger is located.
   Primary DNS server	You can ignore this parameter if the SmartLogger connects to the LAN. Set this parameter to the IP address of the LAN router when the SmartLogger connects to the public network (for example, connecting to the hosting cloud server, email server, or third-party FTP server).
   Secondary DNS server	In normal cases, you can ignore this parameter. If the primary DNS server cannot resolve the domain name, the secondary DNS server is used.

2. Set management system parameters.
   • Method 1: When the SmartLogger connects to a Huawei or third-party management system using the encrypted Modbus TCP protocol, set management system parameters and click Submit.

     After a Huawei NMS or a third-party NMS is connected to the SmartLogger in Management System, another third-party NMS can be connected through Management System-1 to obtain data from the SmartLogger and configure the SmartLogger.

   Table 6-2 Management System

   Parameter	Description
   Server	Set this parameter to the IP address or domain name of the Management System.
   Port	Set this parameter based on the connected Management System.
   Address mode	The value can be Comm. Address or Logical address. If the communications address of the device connected to the SmartLogger is unique, you are advised to select Comm. Address. In other cases, you must select Logical address.
   SSL encryption	Retain the default value Enable. NOTE: If this parameter is set to Disable, data exchange between the SmartLogger and the management system will not be encrypted, which poses security risks.
   Second challenge authentication	Set this parameter based on the connected management system. NOTE: If this parameter is set to Disable, the second challenge authentication result is not checked, and user data may be stolen. Therefore, exercise caution when setting this parameter.
   Security certificate	Optional. Set this parameter only when the certificate has expired or the customer needs to use their own certificate.

   Table 6-3 Management system-1 parameters

   Parameter	Description
   Server	Set this parameter to the IP address or domain name of Management System-1.
   Port	Set this parameter based on the connected Management System-1.
   Address mode	The value can be Comm. Address or Logical address. If the communications address of the device connected to the SmartLogger is unique, you are advised to select Comm. Address. In other cases, you must select Logical address.
   TLS encryption	Retain the default value Enable. NOTE: If this parameter is set to Disable, data exchange between the SmartLogger and the management system will not be encrypted, which poses security risks.
   TLS version	Set this parameter based on the connected Management System-1. TLS1.2 or a later version is recommended.
   Remote permission	Monitoring only, Management (permanent authorization), and Management (temporary authorization) are supported. When the remaining authorization time becomes 0, the system automatically switches to the monitoring-only mode.
   Authorization time	Set this parameter based on the actual authorization time.

   • Method 2: When the SmartLogger connects to a third-party management system using the unencrypted Modbus TCP protocol, set Modbus TCP parameters and click Submit.
   Figure 6-32 Setting Modbus TCP parameters
   

   Parameter	Description
   Link setting	Modbus TCP is a universal standard protocol used to connect to a third-party management system. Because there is no security authentication mechanism, data transmitted by Modbus TCP is not encrypted. To reduce network security risks, the function of connecting to a third-party management system using Modbus TCP is disabled by default. This protocol can transmit the running data and control commands of PV plants, which may cause user data breach and control permission theft. Therefore, exercise caution when using this protocol. Users are liable for any loss caused by the use of this protocol to connect to a third-party management system (non-secure protocol). Users are advised to take measures at the plant level to reduce security risks, or use Huawei management system to mitigate the risks. To use this function, set this parameter to Enable(Limited) or Enable(Unlimited). If this parameter is set to Enable(Limited), the SmartLogger can connect to a maximum of five preset third-party management systems. If this parameter is set to Enable(Unlimited), the SmartLogger can connect to a maximum of five third-party management systems with a valid IP address.
   Client N IP Address NOTE: N is 1, 2, 3, 4, or 5.	If Link setting is set to Enable(Limited), set this parameter based on the IP address of the third-party management system.
   Address mode	The value can be Comm. Address or Logical address. If the communications address of the device connected to the SmartLogger is unique, you are advised to select Comm. Address. In other cases, you must select Logical address.
   SmartLogger address	Set this parameter to the communication address of the SmartLogger.

   • Method 3: When the SmartLogger connects to a third-party management system over IEC104, set IEC104 parameters and click Submit.
   Figure 6-33 Setting IEC104 parameters
   

   Tab	Parameter	Description
   Basic parameters	Link setting	IEC104 is a universal standard protocol used to connect to a third-party management system. Because there is no security authentication mechanism, data transmitted by IEC104 is not encrypted. To reduce network security risks, the function of connecting to a third-party management system using IEC104 is disabled by default. This protocol can transmit the running data and control commands of PV plants, which may cause user data breach and control permission theft. Therefore, exercise caution when using this protocol. Users are liable for any loss caused by the use of this protocol to connect to a third-party management system (non-secure protocol). Users are advised to take measures at the PV plant level to reduce security risks, or use Huawei management system to mitigate the risks. To use this function, set this parameter to Enable(Limited) or Enable(Unlimited). If this parameter is set to Enable(Limited), the SmartLogger can connect to a maximum of five preset third-party management systems. If this parameter is set to Enable(Unlimited), the SmartLogger can connect to a maximum of five third-party management systems with a valid IP address.
   	Public IP address	Set these parameters as required.
   IEC104-N NOTE: N is 1, 2, 3, 4, or 5.	IEC104-N IP	If Link setting is set to Enable(Limited), set this parameter based on the IP address of the third-party management system.
   	Teleindication default segment	Set these parameters as required. NOTE: After the IEC104 configuration file exported from the SmartLogger and the IEC104 information files delivered with devices are correctly configured in a third-party management system, the third-party management system will be able to monitor devices connected to the SmartLogger over the IEC104 protocol.
