RS485-Ethernet Converter and Cloud Gateway

Nicolas Vodoz Updated by Nicolas Vodoz

RS485-Ethernet Converter (Modbus RTU to Modbus TCP)

The RS485-Ethernet converter allows for switching from an RS485 bus network to a TCP/IP network and thus reading Modbus RTU devices via Modbus TCP.

The provided model is a Protoss-PE11 delivered configured and 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 several buildings (microgrid) connected to the same IP network, an RS485-Ethernet converter is installed in each electrical panel and the electricity meters are connected via the RS485 bus. Then, only a single Climkit Gateway is needed to read all the site's meters via Modbus TCP.

In cases where other service providers need to read the same Modbus meters, installing a converter allows for simultaneous reading 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 installing one physically.

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

Features currently possible in this configuration:

  • Reading of Modbus RS485 electricity meters
