5.2 Operation When Trace is Selected for Application

The following operations are executed when the start operation is requested.

 Registered data is confirmed.

 The logging/trace active flags (SR100, SR110, SR120 ...) turn on.

 All other flags than the logging/trace active flag for LOG n are cleared during the start

request operation.

 Once writing data into an SD memory card becomes enabled after the logging/trace active

flags (SR100, SR110, SR122 ...) turned on, the SD card logging active flags (SR101, SR111,

SR112 ...) turn on.

 When the box of "Write file after completion of trace" has been checked in the LOG file

settings dialog box, an operation error occurs if no SD memory card that is normally

readable and writable is inserted, or the card cover is open.

 Operation when switching from RUN mode to PROG. mode

 All logging operations stop.

 The data stored in the buffer memory of the CPU unit is discarded.

 Operation When Power Supply Turns Off

 The data stored in the logging buffer (RAM) of the CPU unit is discarded.

NOTE



In case of the middle of file writing into an SD memory card, written data or

files may be damaged, or the SD memory itself may not be read.
