10.1 Troubleshooting procedure
Bit selection, trace 1...
In the example, the signal SGE–NCK has been read–in to graphic 1 for trace 1.
The following screen is displayed when the vertical "Bit selection trace 1..." softkey
is pressed:
The bits of this signal are consecutively numbered. Every bit is permanently as-
signed an associated bit name. In the input box "track", by assigning a value in the
range between 0..9 it is possible to define in which of the 10 character channels
(tracks) the bit should be graphically displayed. In the example, for trace 1, bit 0
SBH/SD deselection NCK is displayed in track 0 of the bit graphic. Bit 19 deselec-
tion ext. Stop C NCK is displayed in track 9 of the bit graphic for trace 1.
The user is shown which track numbers have already been allocated (in the label
"track number:" they have a blue background) If a track number is allocated twice,
an error message is displayed. All of the signal bits are listed; bits that are not
available are either designated as free or reserved. Using the scrollbar, it is pos-
sible to scroll over the bit range from 0 to bit 31.
Starting values for the track assignments have been entered into the file
F:\hmi_adv\ibsvtsi.ini. If the user does not like these, then he can make the ap-
propriate changes. These changes to the bit graphics become effective by press-
ing the vertical "Accept" softkey and are also transferred into the file hmi_adv\ibsvt-
si.ini as new starting values. This means that they also apply for new
measurements with this signal as default settings.
Using the vertical "Abort" softkey, the screen is exited without accepting possible
changes made to values.
