User Manual PROFview XL 4 The PROFview XL Application Software
If it is not possible to determine all measured values for a station (see Section 3.2 "Measuring the physical
bus characteristics") during the set timeout time (see Section 4.12 "Settings"), "Timeout" is displayed. In this
case, check the status of the station in question or increase the timeout time.
4.8.3 Evaluation
The start time and the accumulated logging time are displayed in the upper part of the view. The measured
values acquired up to this point can be evaluated even while the measurement is still running. It is also possi-
ble to switch between different stations. The left mouse button can be used to highlight measured values if
necessary. The time stamp is displayed for this measured value at the bottom of the screen. All times indicat-
ed in this view are based on the time set in the PC.
To maintain an overview with many measured values, use the zoom-out function. Holding down the right
mouse button and moving the mouse pointer to the left or to the right will mark an area in blue, which is then
zoomed out when you release the mouse button. In the zoomed-out area, you can navigate using the scroll-
bar. Double-clicking with the left mouse button will zoom-in the displayed section so that you can see all mea-
sured values.
With the automatic evaluation activated, a red line symbolizing the critical quality level is displayed. A mea-
sured value that lies below this limit is displayed in yellow; otherwise, in green. The text fields beneath "Evalu-
ation" provide an overview of the entire measurement and indicate how often a station could not be measured
(e.g. due to logger intervals being too short), how often a timeout occurred (not all measured values of a sta-
tion determined during the set timeout time) and whether and how often the value has fallen below the critical
quality level.
4.9 "Statistics of measuring points"
The "Statistics of measuring points" view serves for evaluation and comparison of the measured data of a
station for all measuring points. The "Statistics" menu item can be used to switch the measured values be-
tween quality level, disturbance-free voltage range and edges. Use the list of stations to select the station
from which you wish the measured values to be displayed.
The selected values measured at the individual measuring points are displayed in the diagram. The order
(from the left to the right) corresponds to the sorting order in the list of measuring points. To obtain an appro-
priate display of the measured-value profile along the bus cabling, this list of measuring points should always
be sorted by the topological order of the connection points.
4.10 Printing a test record
After all measurements have been completed, a comprehensive test record can be printed via the PBT appli-
cation software to document the correct functioning of a PROFIBUS plant or to show detected problems. The
test record consists of individual data areas. Each time before printing or displaying the print preview, you can
adapt the compilation of the individual data areas for a selected measuring point and the appropriate station
according to your requirements. To this end, the dialog box shown in Fig. 11 is displayed each time when you
call a print preview or request printing so that you can adapt the test record accordingly.
Use the "Print options" menu item to select the data areas to be displayed or omitted in the test record. All
settings made in this dialog box are saved in the document currently active.
