Diagnostic Monitor Profibus

With the new isNet DPMon and isNet PAMon modules the main module isNet Cube can be enhanced by new diagnosis and protocol monitor functions. The modules detects and diagnoses sporadically occurring problems during data transmission on a Profibus network. The modules identifies configuration problems in the transmission protocol as well as electrical faults that cause interruptions.
The DP monitor module offers one channel that can be connected to the Profibus network via a D-DUB 9 connector. The PA monitor module offers two channels working independently from each other that can be connected to the Profibus network via screwtype terminals.
Both monitores work totally passive; no telegrams are sent to the bus. The modules evaluate the status of all stations on the bus and provide a concise overview about it if needed. In this view the bus status of every single layer of the OSI reference model is separately detected and can also be addressed separately. As additional features the modules offers a protocol monitor, an integrated oscilloscope and an extensive analysis of statistic data, e.g. error counters or average time intervals. Long term monitoring allows autonomous operation for a long period of time even if the NetCube is not connected to the PC. The protocol file is saved on a memory card and can later be downloaded to a PC.
Sophisticated filter and trigger possibilities restrict the data volume and allow for tailored start and stop conditions of the monitoring. Main module Access to the data network is provided by the Ethernet-access RJ-45 in the main module. Therefore transfer rates of 10 Mbit/s and 100 Mbit/s are supported.
