Communication with '[IP Address redacted] - Modbus Server1' has been lost.

[aja1280]

Hello EcoStruxure IT Community,

I hope this is the right forum for my inquiry, or if not, I’d appreciate being pointed in the right direction.

• Data Center Expert Version: 7.9.3
• UPS Model: Vertiv EX60KVA

We’ve been receiving email notifications every five minutes indicating that communication with the Modbus server has been lost.

However, we can access the UPS's web interface and confirm that both the UPS and communication status are reported as Normal.

In Data Center Expert (DCE), we see an active alert indicating a Link Status Failure (screenshot attached).

Troubleshooting Steps Taken:

• Rebooted the communication card (Support -> Enable -> Restart Card)
• Rebooted the DCE server (File -> Reboot Server)

After these steps, we successfully logged back into both the UPS web interface and DCE, confirming device visibility. However, the same error persists.

Any insights, advice, or troubleshooting suggestions would be greatly appreciated!

Thank you!
