RS485-Ethernet Converter and Cloud Gateway

Nicolas Vodoz Updated by Nicolas Vodoz

RS485-Ethernet Converter (Modbus RTU to Modbus TCP)

The RS485-Ethernet converter enables the transition from an RS485 bus network to a TCP/IP network, allowing the reading of Modbus RTU devices via Modbus TCP.

The provided model is a Protoss-PE11, delivered pre-configured with its 24V DC DIN rail power supply.

Generally, the RS485-Ethernet converter is used in "Cloud Gateway" mode (see below).

Other Use Cases

In the case of a site with multiple buildings (microgrid) connected to the same IP network, an RS485-Ethernet converter is installed in each electrical panel, connecting the electrical meters via the RS485 bus. Then, a single Climkit Gateway is sufficient to read all the meters on the site via Modbus TCP.

If other service providers need to read the same Modbus meters, the installation of a converter allows for simultaneous read requests, which is not possible on a simple RS485 bus network.

Cloud Gateway

The Climkit "Cloud Gateway" consists of virtualizing the Climkit Gateway in the cloud to avoid the need for physical installation.

This option is only possible with the combined use of a Teltonika router (TRB140 or RUT300) and an RS485-Ethernet converter.

Currently possible features in this configuration:

  • Reading Modbus RS485 electrical meters
