Adding Signals Using Drag-and-Drop
À To add a signal
The drag-and-drop feature
allows you to trend
automatically named signals
from Innovation Series
controllers and drives. 1. From the Block Area/Summary View (or Detached Summary View ),
click on a pin or a signal name in a block diagram.
2. Drag the signal (using the mouse) to the top view of the Trend Window and
drop (release the mouse button). The
Trend Recorder Channel
Configuration dialog box displays.
When a signal is added to the Trend Recorder from a controller, the toolbox checks
to see if the signal is an internal signal or an external DLAN+ signal. If it is an
internal signal, token (address) information should exist in the device for the signal.
This information is used to trend the signal.
If the signal is an external (DLAN+) signal, the toolbox attempts to find the signal in
the SDB. If it finds the signal, it determines if the signal is available on the DLAN+
that the device is attached to. Then, the signal can be trended.
Note When a signal cannot be added or trending cannot be performed, an
appropriate error message displays. Follow the instructions from the message box to
correct the situation.
Once the signal is added to the trend, the range (upper and lower limits of Y-axis)
and other properties related to the signal can be set in several ways (see the next
section, Editing Properties).

To set the signal range and other properties
Click on the signal in the
lower Signal View with the

Channel Configuration Dialog Box
Sets the upper
and lower limits of
the Y-axis labels
for the signal(s). Allows you to
change the color,
line style, and line
thickness of the
pen used to
outline the trace
for the signal. A
trace is a visible
indication of the
path of a signal.
Click to display the Signal Scaling dialog box to
provide scaling for either an internal signal in a drive
or an external DLAN+ signal in a controller.
(See the next dialog box,
Signal Scaling.)
Note If the line width is greater than one, only solid style is available.
