   • Method 2: If the SmartLogger connects to the management system over a wired network, choose Settings > Comm. Param. > Wired Network, set wired network parameters, and click Submit.

   Parameter	Description
   WAN/LAN/SFP port	Supports five configurations: Ethernet1/Ethernet2/Ethernet1, Ethernet2/Ethernet2/Ethernet1, Ethernet1/Ethernet1/Ethernet1, Ethernet1/Ethernet2/Ethernet2, and Ethernet1/Ethernet2/Ethernet3. Ethernet1/Ethernet2/Ethernet1 is used for a fiber ring network between the SACUs or an FE network between southbound devices and the SACUs, indicating that the WAN/SFP port is Ethernet1 and the LAN port is Ethernet2. Ethernet2/Ethernet2/Ethernet1 is used to connect the LAN port of a third-party device or for a northbound network of the SACUs through the optical port, indicating that the WAN/LAN port is Ethernet2 and the SFP port is Ethernet1. Ethernet1/Ethernet1/Ethernet1 is used for communication between the WAN/LAN/SFP port, indicating that the WAN/LAN/SFP port is Ethernet1. Ethernet1/Ethernet2/Ethernet2 is used for a northbound network of the SACUs through the WAN port when the optical port is directly connected to the CMU, indicating that the WAN port is Ethernet1 and the LAN/SFP port is Ethernet2. Ethernet1/Ethernet2/Ethernet3 is used when the three networks are isolated and different network segments are configured, indicating that the WAN port is Ethernet1, the LAN port is Ethernet2, and the SFP port is Ethernet3.
   RSTP root node	This parameter is displayed when WAN/LAN/SFP port is set to Ethernet1/Ethernet2/Ethernet2 for a northbound network of the SACUs through the WAN port when the optical port is directly connected to the CMU. Set this parameter to Enabled. NOTE: After this parameter is set to Enabled or Disabled, the SmartLogger automatically restarts. If this parameter is set to Disabled, the communication network may be unstable. Exercise caution when setting this parameter.
   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 FusionSolar SmartPVMS, 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. Choose Settings > Comm. Param. > Management System and 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.

   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.
   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. TLS1.2 or a later version is recommended.
   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.

   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.

   • 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 6-36 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 over this protocol 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 connecting to a third-party management system (non-secure protocol) using this 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.
   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 IEC 104, set IEC 104 parameters and click Submit.
   Figure 6-37 Setting IEC 104 parameters
   

   Tab	Parameter	Description
   Basic parameters	Link setting	IEC 104 is a universal standard protocol used to connect to a third-party management system. Because there is no security authentication mechanism, data transmitted over this protocol is not encrypted. To reduce network security risks, the function of connecting to a third-party management system using IEC 104 is disabled by default. This protocol can transmit the running data and control commands of 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 connecting to a third-party management system (non-secure protocol) using this 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 communicates with the management system of the specified IP address, that is, using a whitelist. If this parameter is set to Enable(Unlimited), the SmartLogger sets the segments and common forwarding tables of teleindication and telemetering through Common Configuration.
   	Public IP address	Set this parameter as required.
   IEC104-N NOTE: In SmartLogger V300R023C00SPC120 and later versions, IEC104-1 to IEC104-10 are displayed. In versions earlier than SmartLogger V300R023C00SPC120, IEC104-1 to IEC104-5 are displayed.	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 this parameter as required. NOTE: After the IEC 104 configuration file exported from the SmartLogger and the device type IEC 104 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 IEC 104.
