5.5.11.1 Basic Operation

The operation for sampling trace is done on GX Works2. Execute the sampling trace function as follows.
For detail on actual operating procedure on GX Works2, refer to "5.5.11.4 Sampling Trace Operating Procedure".
Sampling trace of each project in the multi-project mode is possible.
(1) Configure trace setting.

(2) Write trace setting to the CNC controller.
(3) Execute trace. The CNC controller starts tracing devices. The execution status during trace is displayed on the trace sta-
tus in GX Works2, and can be checked by the special relay SM800 to SM805 of the CNC. Trace continues until the fol-
lowing conditions are met.
(a) Tracing is completed upon establishment of trigger.
(b) Stop tracing from GX Works2.
(c) Turn the CNC controller power OFF.
(d) PLC turns to STOP mode.
(4) Read the trace data from the CNC controller.
(5) Display the result, and, if necessary, output the result to a file.

 The trace conditions (setting) set in (1) are retained even after the CNC is powered OFF.
 The trace data obtained in (4) are erased after the CNC is powered OFF.
 The trace conditions are retained in (2). If the CNC power is turned OFF before the settings are written, the conditions
changed before settings are written are not retained, and the previous trace conditions are retained.

Set trace count to be saved. Data items for trace count from the latest data are saved. When trace
count is exceeded, data is deleted from the oldest one.
Set the trace count executed from the trigger is established until the sampling completes.

can be set.
Set the timing of trigger. When trigger is established, status of trace device is taken in." "At the
Time of Manual Trigger Execution" or "Detail Setting" can be selected. "Detail" enables the trigger
establishment condition setting.
