Gateway EG-200

The EG-200 is an open Linux gateway, with RS485 Modbus RTU, Modbus TCP and MQTT, HTTP & SNMP interfaces.

 

Gateway EG

Any Modbus device can be read from or written to via plugins, and all collected data is published to an onboard MQTT message broker as well as logged to uSD card. Live readings or aggregations (1/5/15/60 minutes) can be securely pushed to any third party cloud service of your choice, or pulled from the data logger, entirely on premises.

A simple plugin development kit, complete with integrated onboard test environment makes it easy to add support for new Modbus devices. Plugins already exist for all eTactica hardware, plus a wide variety of third party devices.

A complete Linux (OpenWrt) SDK is also provided for running your own scripts, third party packages or further customizing the firmware.

The EG-200 can also function in simple Modbus TCP/RTU bridge mode, connecting existing Modbus/RTU infrastructure via ethernet or wireless.
