Extensive capabilities for physical-layer diagnostics are now a standard integrated feature for all ISbus Series Fieldbus Power Supplies (photo). This integrated functionality enables complete and continuous plant monitoring across Foundation fieldbus H1 segments at nearly no extra cost. In addition to ensuring overload and short-circuit detection, this solution facilitates continuous monitoring of all quality-relevant physical parameters of the fieldbus: trunk voltage and current, signal and noise levels, line unbalance and especially jitter. A serial interface ensures connectivity for readouts from any standard PC, with no need for special drivers or DMTs. — R. Stahl, Waldenburg, Germany
