TraceSamp
The TraceSamp instruction performs sampling for a data trace.
The TraceSamp instruction performs sampling for a data trace. The sampling settings are specified
from the Sysmac Studio. The present values for all variables that are set to be sampled are read and
stored with trace number TraceNo and sampling point number Point in trace memory. This instruction is
executed only during execution of data tracing and only when the sampling timing is set to sampling
instructions from the Sysmac Studio.
The following figure shows a programming example. Trace number 1 and sampling point number 2 are
attached, and the present values of all variables to be sampled are stored in trace memory.
