What causes fault code ASRS-006 (AS/RS WMS Communication Timeout)?

WMS server down or unresponsive. Network switch between crane controller and WMS failed. WMS database lock or timeout — query taking too long. Firewall rule blocking crane-to-WMS traffic. API endpoint changed during WMS update

How do I fix fault code ASRS-006?

Check WMS application status — restart if needed. Verify network connectivity — ping WMS server from crane controller. Check network switches in the path — verify port LEDs. Review firewall rules if recently changed. Check WMS event log for errors at the time of communication loss. Restart crane controller communication service

Fix Steps

1 Check WMS application status — restart if needed
2 Verify network connectivity — ping WMS server from crane controller
3 Check network switches in the path — verify port LEDs
4 Review firewall rules if recently changed

Field Trick

Ping the WMS server continuously while the crane runs. If pings succeed but commands fail, it's the WMS application, not the network.
