Check if the initialization flag and run flag of the status word are set to 1.
7.3 Some items are not displayed in the Live List
Confirm that the slave address is within the range of 1-64.
Check if the slave station has been correctly connected to the bus and if the power supply is functioning properly.
For PROFIBUS, confirm that the GSD file configuration of the slave station is correct and there are no conflicts in the station address.
For EtherNet/IP, there is no Live List and connection statistics should be used.
7.4 Data behavior after offline does not meet expectations
Enter menu 6 and check if the Offline option is the desired value (Clear or Freeze). Save and restart after modification.
7.5 Frequent gateway restarts
Check if the power supply is stable and if the fluctuation exceeds ± 10%.
If 'Reboot after disconnection' is enabled and the transport provider connection is extremely unstable, the gateway may restart repeatedly. You can try disabling this option.
Check if the universal error counter is growing rapidly. If it grows too fast, it indicates that the gateway cycle has timed out, which may be due to excessive data volume or slow network response on one side.

Engineering Practice Suggestions
Before the first configuration, backup the factory configuration: use menu 7 to upload the initial configuration to the computer to prevent errors that cannot be restored after modification.
Gradually enable advanced features: If control words/status words/Live List are not used, keeping the default "Disabled" can reduce data mapping complexity and communication overhead.
Reasonable setting of offline timeout: If both networks are deterministic fieldbus (such as PROFIBUS DP), the timeout can be set to 0 (disabled), relying on the watchdog mechanism of the bus itself; If one side is Ethernet and there is a possibility of instantaneous disconnection, setting a reasonable timeout (such as 1000ms) can avoid frequent triggering of offline actions.
Record configuration changes: After each key parameter change (such as I/O size, offline strategy), use menu 7 to upload a new configuration file and archive it to the project folder.
Pay attention to error counters: During the debugging phase, frequently check the error counters in menu 5. If they continue to increase, investigate issues such as bus load, cable length, and terminal resistance.
