ST100 Series HART4 Fluid Components International LLCTopology and Network ConfigurationThe ST100 supports Multidrop topology. In multidrop operation, the devices exchange data and measured values only via the HART protocol/HARTNetwork. In Network configuration the analog current signal serves just to energize the two-wire devices, providing a current of 4 mA per instrument.In multidrop mode, up to 15 field devices are connected in parallel to a single wire pair or segment (Figure 4). The host distinguishes the field devicesby their preset addresses that range from 1 to 255. The factory preset address is 0.Figure 4 - Multidrop Mode with HART Transmitters
