SINUMERIK 840D/810D Start-Up Guide (IADC) – 03/2006 Edition
When you press this soft key, the area between the two X markers is extended
over the time axis so that it fills the entire available area of the display. This
allows signal curves to be monitored in more detail.

Further markers can be set in the extended image and, once another time inter-
val has been specified, to zoom using 2 X markers.
If measured value curves (trace1, trace 2 or trace 3, trace 4) coincide in the dis-
play, making them difficult to evaluate, the activated trace can be moved to a
suitable position using Cursor Up or Cursor Down.
10.7.4 Display bit graph for SI signals
10 tracks from 10 signal bits from Safety Integrated can be displayed in graphs
over the measurement period. They are triggered and measured as described
in the previous sections.
S Selection of the signals
S Assignment of signal bits to tracks
S Signals displayed as bit graphs
If Signal selection was used to select a bit-coded SI signal, there is a vertical
soft key called “Bit selection trace i” for the corresponding trace.
