Reports communication loss; look at energy meter; do: network connection check.

What can be behind Communication loss

Failure modes that present as the reported condition, and the tests that tell them apart.

Tell apartByHow
Device firmware defect vs Monitoring network configuration fault drafted · leadCommunication test proposedSwitch the Modbus TCP server parameter off and back on. If communication returns, the problem is limited to Modbus TCP. If it stays down, check the network cabling and RJ45 connections.
