Tracing Data
The Data Trace function samples specified I/O memory data using any one of
the following timing methods. It stores the sampled data in Trace Memory,
where they can be read and checked later from the CX-Programmer.
• Specified sampling time (10 to 2,550 ms in 10-ms units)
• One sample per cycle
• When the TRACE MEMORY SAMPLING instruction (TRSM(045)) is exe-
cuted
Up to 31 bits and 6 words in I/O memory can be specified for sampling.
Basic Procedure
1,2,3...
1.
Sampling will start when the parameters have been set from the CX-Pro-
grammer and the command to start tracing has been executed.
2.
Sampled data (after step 1 above) will be traced when the trace trigger
condition is met, and the data just after the delay (see note 1) will be stored
in Trace Memory.
3.
Memory data will be sampled until the Trace Memory is full, and then the
trace will be ended.
Note
Delay value: Specifies how many sampling periods to offset the sampling in
Trace Memory from when the trace condition is met. The setting ranges are
shown in the following table.
Positive delay: Store data delayed by the set delay.
Negative delay: Store previous data according go to the set delay.
Example:
Sampling at 10 ms with a –30 ms delay time yields –30 × 10 =
300 ms, so data 300 ms before the trigger will be stored.
