Stahl offers a range of fieldbus power supplies and diagnosis modules that help to detect overloads or short circuits but also monitors and registers relevant performance criteria: voltage and current on the trunk, communication level, noise level, asymmetries (shielding termination) and jitter on the segment and on the fieldbus device level. Especially the integration of a jitter monitoring is, according to Stahl an all new feature and a novelty among fieldbus analytics.

The ISbus units, equipped with line quality monitoring features, offer comprehensive functions and maximum flexibility to ensure permanent plant availability – if required, by means of proactive measures. A serial interface can be used to connect the device with standard computers so that the physical layer data can be read out without the need for special driver software.
