Functional principle
The DX80 Data Radios are self-organizing. They create a network in tree topology. They transfer Modbus RTU telegrams or other data from other bus systems. The telegrams are routed through the network and lost radio communication is compensated via alternative routes. Further sensors can be added to the network and their data is accessible via internal registers. Each network consists of a master and an unlimited number of repeaters or slaves. The device type is adjusted via DIP switch. This system can be combined with several DX80 networks to transfer data from the DX80 gateway via Modbus RTU to the control system. Directives: FCC‐ID UE300DX80‐2400. This device complies with FCC para. 15, subpara. C, 15.247 ETSI/EN: In compliance with EN 300 328: V1.8.1 (2014‐04) IC: 7044A‐DX8024 Radiation protection 10 V/m for 80-2700 MHz acc. to EN 61000-6-2 Shock and vibration resistant: IEC 68-2-6 and IEC 68-2-7
