Table 3.14 AUD Trace Acquisition Mode
Type Mode Description
Continuous
trace occurs
Realtime trace When the next branch occurs while the trace information is
being output, all the information may not be output. The user
program can be executed in realtime, but some trace
information will be lost.
Non realtime trace When the next branch occurs while the trace information is
being output, the CPU stops operations until the information
is output. The user program is not executed in realtime.
Trace buffer
full
Trace continue This function overwrites the latest trace information to store
the oldest trace information.
Trace stop After the trace buffer becomes full, the trace information is no
longer acquired. The user program is continuously executed.
To set the AUD trace acquisition mode, click the [Trace] window with the right mouse button and
select [Setting] from the pop-up menu to display the [I-Trace/AUD-Trace acquisition] dialog box.
The AUD trace acquisition mode can be set in the [AUD mode1], [AUD mode2], or [AUD
mode3] group box in the [Trace mode] page of the [I-Trace/AUD-Trace acquisition] dialog box.
