Modbus RS-485 Notes
If a cellular network is not available or you prefer to connect directly to an onsite SCADA or datalogger, ARES and
Wash Extension devices can function as Modbus RS-485 slave devices and stream data to a master device.
However, a Modbus-only communication is not recommended because of the loss of additional processing
performed in the Fracsun cloud (like daily soiling/insolation calculations, wash optimization schedules, and
financials). The most flexible option to have data in your DAS platform and the Fracsun cloud, is to use our RESTful
API. To connect via Modbus, please review the Modbus Documentation on the website.
