Ethernet — Configuration

The Ethernet Add-On adds a single Ethernet port to the Gateway V4, enabling IP connectivity and Modbus TCP reading.

Compatible product: Gateway V4 + Ethernet

Firmware pre-release

Available starting with firmware v0.11.0 (pre-release).

Ethernet Configuration​

The Ethernet interface is configured using the EdgeEth parameter as a static IP (ip,netmask,gateway) or dhcp.

Example — static:

192.168.1.91,255.255.255.0,192.168.1.1

Example — DHCP:

dhcp
note

No spaces allowed. Only IPv4 supported. DNS not supported — use IP addresses directly.

Modbus TCP Configuration​

Modbus TCP commands are added to the modbusCmdConf parameter using an IP address as the interface specifier. The interface and commands are separated by /, multiple interface groups by ;.

Syntax:

<ip>/commands;<ip:port>/commands
  • 192.168.1.222 → Modbus TCP, default port 502
  • 192.168.1.222:1234 → Modbus TCP, custom port

Supported command codes: 01 Read Coils · 02 Read Discrete Inputs · 03 Read Holding Registers · 04 Read Input Registers

Example:

192.168.1.200/010380000001,020300010002

RS-485 and Modbus TCP can be combined in one modbusCmdConf string:

R,9600,8N1/010300000003,FA0400080002;192.168.1.200/010380000001
Different from standard Modbus format

This unified format uses / (interface↔commands) and ; (between interface groups) — different from the standard Modbus Add-On format which uses :.
