Edge — Configuration
The Edge Add-On extends the Gateway V4 with 2× Ethernet, wired M-Bus, Modbus RTU/ASCII (RS-485) and Modbus TCP in a DIN-rail form factor.
Compatible product: Gateway V4 + Edge
Available starting with firmware v0.11.0 (pre-release).
Ethernet Configuration
Both Ethernet ports are configured using the EdgeEth parameter. Each entry specifies ip,netmask,gateway or dhcp. The two port configs are separated by |.
Syntax:
<ETH1-config>|<ETH2-config>
Example — ETH 1 static, ETH 2 DHCP:
192.168.1.91,255.255.255.0,192.168.1.1|dhcp
| Port | Label | Usage |
|---|---|---|
| ETH 1 | LAN | Modbus TCP (currently only this port) |
| ETH 2 | WAN | Uplink (planned) |
No spaces allowed. Only IPv4 supported. DNS not supported — use IP addresses directly.
Modbus Configuration (modbusCmdConf)
The Edge uses a unified modbusCmdConf format that covers RS-485 (RTU/ASCII) and Modbus TCP in a single parameter. Each interface group is separated by ;, with the interface specifier and commands separated by /.
Syntax:
<interface>/<commands>;<interface>/<commands>
Interface specifiers:
| Interface | Example | Description |
|---|---|---|
| Modbus RTU | R,9600,8N1 | RS-485, RTU mode |
| Modbus ASCII | A,19200,7E1 | RS-485, ASCII mode |
| Modbus TCP | 192.168.1.200 | TCP, default port 502 |
| Modbus TCP (custom port) | 192.168.1.200:1234 | TCP, custom port |
Supported command codes: 01 Read Coils · 02 Read Discrete Inputs · 03 Read Holding Registers · 04 Read Input Registers
Example — RS-485 + Modbus TCP combined:
R,9600,8N1/010300000003,FA0400080002;192.168.1.200/010380000001
R,9600,8N1/...— Modbus RTU over RS-485FA04...— internal gateway sensor (special addressFA)192.168.1.200/...— Modbus TCP to ETH 1, port 502
This format uses / (interface↔commands) and ; (between groups) — different from the standard Modbus Add-On which uses :.
Wired M-Bus
The Edge also supports wired M-Bus meter reading. See the M-Bus Add-On documentation for configuration details.
