Introduction

NODA Modbus Gateway provides a reliable Modbus TCP master/slave solution where data transmits over a secure MQTT connection.

The Modbus Gateway acts as a Modbus TCP or RTU master/slave. It can communicate with any Modbus TCP slave connected via the LAN interface or act as a Modbus TCP slave. It can also communicate with any Modbus RTU slave connected via an RS-485.

Data is transmitted over the mobile network using a 4G or 5G modem internal to the gateway. The LAN interface or the RS-485 bus is not used to transfer outbound data to NODA. Only the WLAN connection via Wired Ethernet or Mobile Internet can access the internet.

For a list of limitations concerning the installation, see the details in Modbus support.
