Inserting a Channel Y-Axis There are two possibilities for the selection of the Y-axis. It is possible to create an individual Y-axis. It is necessary in that case to specify the lower and upper bounds. It is also possible for one Y-axis to be linked to another. In that case the display bounds are adopted from the given channel, and no separate Y-axis is displayed. Show Channel The "Show Channel" switch allows the display of a channel in the Scope View to be activated or deactivated. Offset and Scaling An offset and a scale factor can be given for each channel. The value read in is then first multiplied by the scale factor, after which the offset is added.
-from TwinCAT Version 2.9 Build 1022 (Scope Build 195): In the xt display, an additional offset can be entered for the time axis (offset X values). This allows you to move any channel on the time axis. When switching to online mode, the X offset is automatically reset to 0. Style The way in which the plot is shown in the Scope View is described on the "Style" properties page. This includes the color and width of the pen. "Style" is also used to define the kind of line, e.g. solid, dashed etc.. It should be noted, however, that the line is always solid if the width of the pen has any value other than 1.
It is often helpful for closer analysis if the individual interpolation points can be seen. This can also be set on this page. In online mode it is better if at all possible, not to draw the interpolation points, as this demands a significant increase in computing power. Scope View 17 Version: 1.1
