Cloud Server

com.tom Cloud Server in a nutshell

The com.tom product series combines telemetry with telecontrol and includes in the package a cloud solution to enable worldwide data access. This makes it possible to respond quickly to the collected data and influence the local process. Process and configuration data are represented as hierarchical trees of nodes both on the com.tom devices and the com.tom PORTAL server. Consumers (users, applications) can subscribe nodes on the PORTAL server. When process data changes the devices send the new values to the PORTAL server which stores it and immediately forwards it to all subscribed consumers. Consumers can control devices by sending configuration data to the PORTAL server which sends it to the respective devices.All this works fast, secure, configurable and scalable.
