Causes and Fixes

1
Access HMI: Navigate to Startup → Service → Settings → Network/HMI Advanced settings menu.
2
Check if ping server IP address is configured. Note the current network settings including IP address, subnet mask, gateway, and DNS servers.
3
Either remove/clear the ping server entry if not needed, OR complete all network parameters (subnet mask, default gateway, DNS) to match your facility network requirements.
Document original settings before making changes. Incorrect network settings can prevent HMI communication.
4
Save configuration, perform NCK/HMI restart, and verify alarm clears and network connectivity functions properly.
