5-1-7-1 Oscilloscope functionality in Trajexia Studio
The software oscilloscope is a standard part of Trajexia Studio. The
oscilloscope can be used to trace and graphically represent axis and system
parameters. This can help you with development, commissioning and
troubleshooting of the motion system. For more information on the software
oscilloscope and its features and capabilities, refer to the Trajexia Studio
manual.
You can trigger the oscilloscope to start tracing given axis and system
parameters in two ways: manually or by a program. Triggering manually is
done using the data trace. The parameters are stored in the Table memory of
the controller. The range of the Table memory where the parameters are
stored can be set in the
Memory Manager
of the device configuration (see the
Trajexia Studio manual). With manual triggering, the user can see the changes
of axis and system parameters in real time, as the system runs. A change in
parameter values is graphically represented as soon as the change happens.
The limitation of manual triggering is that it requires user interaction, which
means that the start of tracing is not synchronized with the movement that is
analyzed. Also, with manual triggering the tracing range is limited to 200
samples per channel.
5-1-7-2 Using the oscilloscope
The alternative, triggering by a program, does not have the limitations of
manual triggering of the tracing. Triggering by a program stores the axis and
system parameters in the memory of the CJ1W-MCH72. Later, the parameters
are given to the oscilloscope for graphical representation. The axis and
system parameters are stored in the Table memory. The memory range used
is defined by the parameters of the
SCOPE
command. When the parameters
are in the Table memory, the oscilloscope can be configured to show a range
of Table memory locations instead of axis and system parameters. The exact
moment when the tracing is started can be exactly determined because it is
controlled by the
TRIGGER
command. This means the start of tracing is
synchronized with the movement.There is no limitation of 200 samples per
channel, the oscilloscope shows as many samples (Table entries) as
configured.
5-1-7-3 Example
This section gives you a practical example on the use of the
SCOPE
and
TRIGGER
commands, and how to use them in combination with the
oscilloscope to monitor axis parameters and troubleshoot the system. For
more information on the
SCOPE
and
TRIGGER
commands, refer to sections
4-2-218 and 4-2-245.
