Modbus TCP/IP
A host system acting as a Modbus master (Client) can access the DXMR90-4K using the Modbus TCP/IP protocol
over Ethernet. Standard Modbus TCP port 502 is used by the DXMR90-4K for all Modbus TCP/IP requests.
All internal local registers are available to the host system concurrently with Modbus TCP.
By default, the DXMR90-4K is configured as a Modbus TCP/IP Server.
