5.5.11.7 Precautions

(1) Trace can be executed for the other stations on the network or with serial communication connection. However, it is not
possible to execute trace from multiple areas at the same time .
(2) The trace conditions registered in the CNC are retained after the CNC power is turned OFF.
Trace data are deleted when the CNC power is turned OFF.
However, the saved data is discarded when any of the following states occurs.
 Data are inconsistent with the saved trace conditions (the trace size and the device range) at the power ON.
 Data are inconsistent with the saved trace conditions (the trace size and the device range) when the multi-project set-
ting is changed from the on-board and the CNC is restarted.
 Data are inconsistent with the saved trace conditions (the trace size and the device range) when USERPLC.LAD which
has different multi-project setting is input through [Mainte] [I/O] on the NC screen and the CNC is restarted.
(3) Sampling trace is executed by connecting CNC controller and GX Works2.
(4) Previous trace data in the CNC are deleted during the execution of trace. Save them before executing trace if necessary.
(5) When trace is ended before reaching the set No. of traces, such as when trigger occurs as soon as trace is started, the
shortened data will not be displayed.
(Example) Trigger condition is met at 10th trace when the number of traces is set to "2000" and the number of traces after
trigger is set to "1000".
