SITELINK-micro/GW1 Gateway


The Sitelink-micro/GW1 Gateway is a gateway for remote monitoring and integration between BMS controllers and Modbus hardware. The Gateway can be used locally at the site level for integration, and can also be cloud connected for remote monitoring, engineering, datalogging and alarming.

The Gateway supports secure tunnelling to allow remote access to BMS web servers and engineering ports over both broadband and 3G.

Remote cloud access also allows remote Modbus and BMS queries to be performed and to remotely log datapoints directly to cloud databases.
