isNet FFMon
With the isNet FFMon module, the main module isNet Lite can be
enhanced by new diagnosis and protocol monitor functions. The
modules detects and diagnoses sporadically occurring problems
during data transmission on a FOUNDATION FIELDBUS network. The
modules identifies configuration problems in the transmission proto-
col as well as electrical faults that cause interruptions.
The FF monitor module offers two channels working independently
from each other that can be connected to the FOUNDATION FIELD-
BUS network via screwtype terminals. The monitor work totally
passive, no telegrams are sent to the bus. The module evaluates the
status of all stations on the bus and provides 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. The module also 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
isNet Lite is not connected to the PC. The protocol file is saved on a
memory card and can later be downloaded to a PC.
The accompanying software isField Diagnosis (see page 67) is used
to access the diagnosis functions.
