RS485-Ethernet Converter and Cloud Gateway

Nicolas Vodoz Updated by Nicolas Vodoz

RS485-Ethernet Converter (Modbus RTU to Modbus TCP)

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

The provided model is a Protoss-PE11, configured and supplied with a DIN rail 24V DC power supply.

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

Other Use Cases

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

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

Cloud Gateway

The Climkit "Cloud Gateway" involves virtualizing the Climkit Gateway in the cloud to eliminate the need for physical installation.

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

Currently available functionalities in this configuration include:

  • Reading Modbus RS485 electricity meters
See the Cloud Gateway configuration (MQTT)
