I. Background The Qidaishan Iron Mine of Ansteel Group was a key project during the Eighth Five-Year Plan period and has served as a landmark construction model for the national mining system since its commissioning. With the continuous deepening of various technological upgrading projects in recent years, especially the continuous improvement of automation levels, the Qidaishan Iron Mine has attracted even more attention from the group's leadership. However, because the equipment in the entire mining area has been in use since the 1990s, there is a lack of synergy between its hardware and software and the equipment developed in recent years with digitalization, informatization, and networking technologies. This leads to particularly serious problems in fault detection. Currently, the crushing station at the Qidaishan Iron Mine of Ansteel Group exhibits the aforementioned issues. The signal screen project for the relocation of the crushing station at Ansteel Group's Qidaishan Iron Mine mainly addresses the issue of intelligent fault diagnosis for medium and low voltage frequency converters. Its primary diagnostic and fault monitoring target is the PowerFlex water pump frequency converter, located tens of kilometers away from the central control room. Fault signals are promptly collected and transmitted to the host computer. If necessary, alarm data is sent to an email address designated by the engineer for fault information analysis and alarm notification. Simultaneously, a ControlLogix controller with a 1756-ENBT/A interface on the same network segment is used to troubleshoot the fault through a pre-programmed fault handling subroutine. [b]II. System Design[/b] The modified system monitors the PowerFlex frequency converter via Ethernet. When a frequency converter malfunctions, the adapter can send alarm information via email. After careful analysis and extensive experimentation, [table][tr][td][/td][/tr][/table], our design scheme is as follows: First, adapter configuration. A 20-COMM-E Ethernet/IP adapter is selected and installed in PowerFlex, with a unique IP address set through the HIM operation panel. Second, accessing the adapter's homepage to monitor frequency converter parameter information. After setting the adapter's IP address, you can view the inverter's information via a webpage. This allows for remote monitoring of the inverter's parameters and operating status via Ethernet. Third, configure the SMTP (Simple Mail Transfer Protocol) server. SMTP is used to transmit emails over the Internet; the inverter can send alarm emails to a designated email address via the configured SMTP server. Fourth, use RSLogix5000 software to control the inverter via Ethernet and read and modify inverter parameters online via Datalink. This allows for remote control of the inverter's parameters and operating status via Ethernet. [b]III. Configuration Process[/b] First, configure the adapter. There are two ways to set its IP address: HIM panel operation and BOOTP server. The specific steps are illustrated in Table 1-1, using panel operation as an example: Table 1-1 Steps for Setting the Inverter IP Address [table][tr][td=1,1,205]Steps[/td][td=1,1,101]Buttons[/td][td=1,1,147]Display[/td][/tr][tr][td=1,1,205]1. Use the up and down arrow buttons to select Device Select from the main menu. 2. Select 20-COMM-E and press Enter to enter the EtherNet/IP adapter settings. 3. Set the adapter IP address using parameters 4 to 7. [td=1,1,101] [td=1,1,147] [td][/tr][/table] After setting the adapter's IP address, you can view the inverter's information through a webpage. The webpage has many inverter information options, as shown in Figure 1: [align=center] Figure 1 Inverter Information Webpage[/align] This system uses Forward Mail Server software to configure the SMTP server. Forward Mail Server is an email server software that can implement all the functions of a traditional mail server. After installing Forward Mail Server, configure it. Enter the local IP address in the Domain name window and set it as the server. In the Local Mailbox window, enter the email address and its domain, for example, set the email address to [email protected] , as shown in Figure 2. In the Management Settings window, uncheck "Enable SMTP Sending Authentication" in the "Mail" tab. In the "Forwarding" tab, uncheck the "Use a remote SMTP server to forward mail" option, and enter the local IP address in the SMTP Server dialog box. Start the Forward Mail Server's SMTP, POP3, and WEB services. The Forward Mail Server setup is now complete. [align=center] Figure 2: Email Name and Domain Settings[/align] In the inverter's web page information item "Configure Email Notification," enter the SMTP server's IP address and recipient email address. Power off the inverter. You will then receive an alarm email from the adapter in your mailbox, as shown in Figure 3: [align=center] Figure 3: Alarm Email[/align] Finally, read and write PowerFlex inverter parameters online via Datalink. Datalink is used to transmit data between the PowerFlex inverter and the controller. Datalinks can change parameter values ​​without external commands. When enabled, each Datalink consumes 16-bit or 32-bit words in the input or output image. The size of its Datalinks (16-bit or 32-bit) is determined by the inverter and is displayed in adapter parameter 19, "Datalink Size." Configure the I/O for data transmission via the adapter by setting parameter 23 [DPI I/O Cfg] of the inverter, and parameter 35 [MS Input] to configure master-slave input data. This data is generated by the master device with a scanner and consumed by the adapter. Parameter 36 [MS Output] is used to configure master-slave output data. This data is generated by the adapter and consumed by the slave device. Select 4 for the number of Datalink channels in the PowerFlex 70-E module properties window. In the Monitor Tags tab of the RSLogix5000 software, users can modify the values ​​corresponding to parameters 300 to 307 of the PowerFlex inverter online by selecting parameters O.userDefinedData[0] to O.userDefinedData[7]. Monitor the values ​​corresponding to parameters 310 to 317 of the PowerFlex inverter by using I.userDefinedData[0] to I.userDefinedData[7]. IV. Conclusion After implementing this solution, the host computer, ControlLogix controller, and PowerFlex inverter in the system are all connected to the Ethernet network, communicating with each other via Ethernet. This enables remote monitoring of the inverter and sending alarms via email. This method significantly increases the number of monitoring nodes, and Ethernet is not limited by connection methods. It is hoped that this solution will be widely adopted in enterprise remote monitoring systems.
