The number between 1 and 8192 can be set. Note that, however, when the max project No. is 1, the
trace data size has to be smaller than 220 kilobytes.
For the trace data size calculation and the size of each max project No., refer to (*1).
Sets the number smaller than the No. of traces.
The trace execution can be repeated.
(After a trace execution, the trace is restarted automatically.) The trace is repeated until the trace
stops.
Each high scan Traces per scan of the PLC high speed process.
<Note>
 The trace data can be set are limited to 8 points or less of bit devices.
 This cannot be selected with the user safety sequence "SafePLC1" or
"SafePLC2". If this is selected, the error occurs when the sampling trace is
executed.
Each main scan Traces per scan of PLC main process.
Trace data change Traces when the device that is set by trace data at every scan of the main
process changed. (Bit device: OFF -> ON, ON -> OFF, Word device: value)
Specified devices Traces when the setup condition of specified devices on the "Trace point set-
up" screen is satisfied at every scan of the main process. Refer to (*2) for the
applicable devices.
Operation Executes trigger by pressing [TRIGGER EXECUTION] button on the trigger
execution screen.
Specified devices Executes trigger by one of the following methods.
 Press the [EXECUTE TRIGGER] button on the trigger execution screen.
 When the setup conditions of specified devices on the trigger point setup
screen are satisfied.
Refer to (*2) for the applicable devices.
Time (Displayed in hour:minute:second)
<Note>
 The step No., program name cannot be added.
50 points of word devices and 50 points of bit devices can be set. Note that, however, when the max
project No. is 1, the trace data size has to be smaller than 220 kilobytes. For the trace data size cal-
culation and the size of each max project No., refer to (*1). Refer to (*3) for the applicable devices.
This starts a trace (data collection) by pressing the [START TRACE] button on the trace execution
screen.
This stops a trace (data collection) by pressing the [STOP TRACE] button on the trace execution
screen.
This displays the data for the number of traces (or the number of traces until the trace stop) on the
trace result display screen.
This outputs the trace result to the external device in CSV file format.
