Causes and Fixes

1
Navigate to HMI Commissioning → Communication → TeleService and verify IP address, subnet mask, and gateway settings match your network requirements.
2
Check physical network connection: verify Ethernet cable is securely connected to the TeleService port (typically X130) and link LED is illuminated green.
3
Test network connectivity by pinging the configured gateway address from the HMI diagnostics network tools to verify basic TCP/IP communication.
4
If using DHCP, verify DHCP server is operational and assigning addresses; consider switching to static IP configuration to eliminate DHCP-related issues.
Changing network settings may temporarily interrupt remote access if currently connected.
