SMARTbox Mini Ethernet

Smartbox, based on the LTE Cat1 Telit Chipset LE910 is a ready to use solution for connecting Modbus devices to the Cumulocity Fieldbus Cloud. It provides a Client Communication on TCP/IP for connecting Modbus Server to the Cloud . Easy configure the SetUp of building automation fielddevices like pumps, e-meters, Airhandling units in the CloudofThings (CoT). Using the MQTT protocol the terminal comes up with a low traffic solution.
