　　Maintenance and Troubleshooting

　　Daily Maintenance:

　　Hardware Inspection: Regularly check the physical condition of controllers, I/O modules, and power modules (e.g., indicator lights, connecting cables) to ensure there are no loose parts, damage, or overheating; use a multimeter to measure the power output voltage to verify it is within the normal range.

　　Software Management: Back up system configurations (e.g., using MarkVIe Configuration Backup Utility), logic configurations, and operating systems; regularly update firmware and software versions, and fix known vulnerabilities.

　　Environmental Monitoring: Maintain the temperature, humidity, and air cleanliness of the electronics room to meet standards, and avoid electromagnetic interference; prohibit the use of wireless communication tools to prevent signal interference.

　　Fault Diagnosis and Handling:

　　Common Fault Types:

　　Power Supply Failure: Check the power module output voltage, connection cables, and load conditions; replace the module if necessary.

　　Communication Interruption: Use network diagnostic tools (e.g., the ping command) to check network connectivity and verify that protocol configurations (e.g., IP address, port) are correct.

　　I/O Module Abnormalities: Check input/output signal lines, sensor status, and module configuration; locate the faulty module using the diagnostic panel or MarkView software.

　　Software Failure: Analyze error codes using system logs (e.g., MarkVIe Logger), restart the control software, or restore the backup configuration.

　　Specialized Tools: Turbine Diagnostics Software (TDS) and MarkVIe Control Software are used for real-time monitoring and diagnostics; MCBU (MarkVIe Configuration Backup Utility) is used for configuration backup and recovery.

　　Competitive Advantages and Industry Position
