Operation with ISD Toolbox
5.7.3.10 Online and Offline Mode
Scope is available in online and offline mode.
When operating in Online mode, the full Scope
functionality is available, including configuring and
performing traces on the device. Offline mode offers the
possibility to open, view, and analyze saved traces.
When operating in Online mode, the Scope sub-tool uses
the trace signal description directly from the device; when
using Offline mode, Scope uses the local Toolbox configu-
ration instead.
When going online with the device or starting Scope for a
device that is already online, the trace signal description
and sampling rates are automatically downloaded from the
device and updated. Furthermore, the device is automat-
ically checked for available trace data.
For Offline devices, the local ISD Toolbox configuration is
used to show the sampling rates.
5.7.3.11 Reports, Document Exporting, and
Printing
For documentation and printing purposes, the Scope offers
a trace reporting functionality that generates a printable
view of the trace. It also facilitates export to a PDF or
spreadsheet file, and direct printing.

5.7.3.12 Multi-device Scope
The Multi-device scope sub-tool itself looks similar to the
single scope sub-tool, but has a list of devices inside the
tool strip. While tracing, an additional window shows the
status for all selected devices.
It is also possible to trace signals across different devices.
Therefore every channel has an additional drop-down box
where the device can be selected for each channel.
The result of all traces is shown in the same diagram (see
Illustration 5.36).

Programming Guide
Illustration 5.36 Result of All Traces
It is possible to mix tracing across different device types,
so it is possible to trace, for example, the power of an SAB
together with the position of a servo drive.
There are different possibilities available for triggering (see
Illustration 5.37):

No triggering takes place. The devices involved all do
an individual trace. They start immediately after the
Run button has been pressed. The first sample of
device 1 is not necessarily taken at exactly the same
time as the first sample of device 2. There is a short
delay between the devices.
same signal. This signal must be available on all
involved devices. Therefore, the Scope reduces the
trigger signals to these signals that are available on all
devices (also across device types!) that are involved in
the tracing.
The trigger condition on 1 single device is configured.
As soon as this event occurs, all other devices trigger
too. The devices that listen to the triggering device
take their first sample with a short delay as the trigger
event must first be communicated. However, their
traces are taken at exactly the same time.
