Description Ethercat Scan Bus Error; Description Ethercat All Ethernet Links Disconnected - GE Mark VIeS System Manual

1000-2024
Description Immediate Attention Required: Fieldbus I/O Module [ ] Not Detected on IoNet [ ]
Possible Cause Note: If this diagnostic is active, the module needs to be replaced immediately. If it is simplex, the
devices under this PFFA have lost communication. If it is redundant and not replaced, and a controller on the remaining
module's IONet goes down, then control is lost for all devices under the PFFA modules.
• PFFA module did not complete Start
• PFFA module configuration files missing
• PFFA module restarted
• PFFA module configured for Hot Backup, but only one network is connected
• Serial connection between PFFA modules is broken
• Network issue
Solution
• If the Control/Status communication is working correctly, any additional diagnostics should indicate the cause of the
problem.
• Build and download parameters to the PFFA module and controller.
• Verify Serial cable is attached correctly.
• Verify that the Ethernet cables and network switch are operating correctly.
• Manually restart the PFFA module.
