Knick’s ComFu radio system facilitates data transmission from sensors which are installed e.g. in inaccessible or mobile measuring points in safe or hazardous areas. ComFu uses the IEEE 802.15.4-based ZigBee standard which enables users to set up so-called Personal Area Networks, allowing terminals and routers to communicate locally. Distance limits due to cable properties are no longer a problem. In the open field, the system bridges a maximum distance of 400 m. It can be easily integrated into the proven, modular Protos process analysis system. The simplest ComFu network consists of two hardware components: a radio receiver/transmitter on the sensor side (ComFu E, end device) and the network coordinator (ComFu C, coordinator) which is connected to a Protos FIU digital module via its RS485 interface. As usual, all components are operated and programmed via the Protos system or via the new ProgaLog 3000 configuration software.
