sequence
Description
Dimension of evaluated variable values
(e.g. °C).
Evaluation of variable values for the dimension
adjustment, linearly through two defined value
assignments.
The variables can be scaled linearly via two
defined points for the display (e.g. byte value 16
corresponds to 20 °C, byte value 128
corresponds to 90 °C).
Display of a variable in byte format; not as a
value, but individually as a binary signal for
each selected bit. Variables configured as byte
can also be displayed as individual bits (BOOL).
If not all of the individual bits are required in the
view, they can be specifically selected for the
display.
The sequence of the variables can be changed
so that they can be compared directly next to
each other.
The horizontal axis is always displayed with a
millisecond specification for each cycle. This
can be changed to the cycle number, each
calculated with the starting point 0 from the
trigger.
PLC trace diagrams can be displayed in a
default setting that can be evaluated on every
monitor.
A complete recording can be displayed in a
compressed format, by means of a zoom
setting in a single view. However, this may
result in a loss of information. Every detail is
displayed in an optimized compressed display,
but in the smallest possible view. The minimum
level of precision that can be set for the graph
view is the pixel level, but marking should allow
a cycle level of precision to be set dynamically.
A graphical or tabular display of the variable
values can be selected.
The display of the data table can be changed
from a horizontal (time/cycle axis) to a vertical
(variable axis) view.
