Functions
Bus Status
> Overview
Bus Status function (Overview) assesses bus physics
and bus communication and displays the test result in a
simplified view.
Bus Status
> Detail view
Bus Status function (Detail view) assesses bus physics
and bus communication and displays the test result in
table form.
Signal Quality
The signal quality test determines the signal quality index
for each bus station and displays the test result in a bar
diagram. The test location is particularly important when
you are testing the signal quality.
Additional information is available such as Signal/ Noise
ratio, edges and numerical values with respect to signal
quality testing.
Signal Quality
> Select test
location
The test location is particularly important when you are
testing the signal quality. It is recommended to make at
least two signal quality tests per physical segment (at
both ends of the corresponding segment).
Signal Quality
> Settings
evaluation
The signal quality evaluation settings contain limit values
for the quality index, signal/noise ratio, rise time and
timeout.
Cable Test
The cable test function examines the cabling in
PROFIBUS segments. This test detects the cable
segment length, scans for unwanted reflections on the
line and verifies proper termination of the cable. In case
of a fault you will get an error description and a distance
indication (if possible) for troubleshooting actions. Tests
regarding cabling can only be made from one end of the
PROFIBUS line. Active stations (Masters, MPI panel,...)
must be disconnected during testing of the respective
cable segment.
For further information and starting points in order to
correctly interprete the fault indication see
indications and remedial measures
.
Cable Test
> Edit
Configuration
In the context of cable testing it is recommended to
provide additional information about the corresponding
cable segment (physical segment). This is important for
proper detection of line length, compliance with
maximum allowed segment length as well as for proper
documentation of test results. Please give full particulars
with respect to the configuration of each cable segment.
