CHAPTER 2 DEPENDENCE FUNCTIONS
2.2.7.3 Trace Sampling Control by Sequencer
When the event mode is in the normal mode, real-time trace executing tracing called
single trace.
If the trace function is enabled, single trace samples all the data from the start of
executing a program until the program is suspended.
■ Trace Sampling Control by Sequencer
Sets up suspend/resume trace sampling for each condition at each level of the sequencer. Figure 2.2-8 shows
the trace sampling flow.
For example, it is possible to suspend trace sampling when event 1 occurs, and then resume trace sampling
when event 2 occurs. Trace data sampling can be restricted.
Figure 2.2-8 Trace Sampling Control (1)
As shown in Figure 2.2-9, trace sampling can be disabled during the period from the start of a program
execution until the first condition occurs. For this setup, use the GO command or the SET GO command.
[Example]
>GO/DISABLETRACE
>SET GO/DISABLETRACE
>GO
