The Profibus PA Diagnostic Monitor, FBT-6-PA
,
is used to examine the operation of a live Profibus-PA
segment without interfering with its operation. The
Monitor is intended for maintenance personnel to
verify segment operation or to troubleshoot an errant
segment.
The FBT-6-PA Diagnostic Monitor
checks for
retransmissions from each device on the segment,
providing a key performance indicator of segment
health. The Monitor also provides measurements of
bus voltage level, device signal level, and peak and
average noise level. It displays the number of devices
present on the segment and indicates when devices
are added or removed from the segment. It also
detects the presence of a short between either of the
signal wires and the cable shield.
Modern fieldbus commissioning procedures
require various bus parameters to be measured
and recorded. Key parameters include bus voltage,
signal level for each device and noise level on
each segment or at every device on each segment.
Recording the results allows a baseline of the fieldbus
physical layer to be established. The Monitor collects
this data, and saves up to eight segment reports
to be saved for transfer to a PC via a USB port.
The reports are saved as Microsoft® Excel files as
a comprehensive commissioning and operations
report. Considerable savings can be achieved by
reducing commissioning time and verifying the
correct operation of the segment.
Data collected from periodic segment
verification testing or during troubleshooting can be
simply transferred to a file for easy comparison to the
segment baseline/history measurements. Data can
be displayed as tables and graphs using Microsoft®
Excel.
Hand-held for portability
, the Monitor is
powered by the fieldbus so that no battery or
external power source is required. It includes colour-
coded test leads and an LCD display.
