5.2 Operation When Trace is Selected for Application

5.2.1 Operation When Trace Operation Starts

The following operations are executed when the start operation is requested.
● Registered data is confirmed.
● The logging/trace active flags (SR100, SR110, SR122 ...) 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.

5.2.2 Operation When Logging Operation Stops

■
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.

5.2.3 Operation when power supply turns off

■

Operation when power supply turns off

● When activating logging/trace, the power off flag during file access SR3F turns on.
● The data stored in the logging buffer (RAM) of the CPU unit is discarded.
● 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.

5.2.4 Operation When the Card Cover of CPU Unit Opens

The following operations are performed when the card cover is open during the trace operation.
■
Operation of system relays
● The logging/trace active flag and the SD card logging active flag stay on while the card cover
is open.
● Although the logging/trace active flag turns off once the trace stop condition is met, the SD
card logging active flag stays on.
● When the card cover is closed, the SD card logging active flag also turns off.
