(g) When file register is designated in designation device with detail setting of
trace conditions
When file register is designated in designation device with detail setting of trace
point and trigger point setting, do not change block No. of file register file and file
register after registry trace.
Trace data may not be normally sampled.
(h) Trace point setting
Note6.46
Note48
When setting the trace point setting as [per time] or [per multiple CPU high speed
transmission cycle], pay attention to the sampling interval and sampling
processing time for one sampling since the sampling trace is performed as
interrupt processing. If the sampling processing time for one sampling is long,
WDT error may occur.
(i) Executing sampling trace during execution of sampling trace
The first sampling trace continues normally. However, the second sampling trace
cannot be executed.
(j) Executing online change (Write during RUN)
Operation will be as follows when sampling trace and online change are executed
simultaneously.
1) Executing sampling trace during execution of online change
When step number is used for specifying the trace point and trigger point,
online change can be executed (completes normally) and sampling trace
cannot be executed.
When other than step number is used for specifying the trace point and trigger
point, both online change and sampling trace can be executed.
2) Executing online change during execution of sampling trace
Only when step number is used for specifying the trace point and trigger point,
sampling trace is stopped and online change can be executed (completes
normally).
When other than step number is used for specifying the trace point and trigger
point, both online change and sampling trace can be executed.
Note48
The High Performance model QCPU, Process CPU, and Redundant CPU cannot set [per
multiple CPU high speed transmission cycle].
