Sampling traces
This is a function which samples the on/off status of the registered relay and the data stored in the register,
either periodically or when the appropriate conditions have been fulfilled, and stores the results in memory. It
can be used to confirm changes in the data.
16 relays points and 3 words of registers can be set.
Procedure for executing a sampling trace
1. Specify registration of the data to be sampled and the sampling method (such as the number of
times or the time interval).
2. Indicate that the sampling trace is to begin.
3. Sampling is carried out.
Sampling can be carried out using with periodic sampling or sampling based on the F155 (SMPL)
instruction.
4. Stops a sampling trace
Programming tool software online operation or executing the F156 (STRG) instruction applies a
stop command trigger. (When a trigger is applied, sampling of the specified delay is carried out, and
then sampling stops.) (The programming tool software can also be used to initiate a forced stop.)
5. The programming tool software can be used to read the sampling results from the CPU, and to
monitor and confirm them.
