Save Operation Log ($SB38)
$SB38 saves operation log data. When $SB38 is turned ON, the operation log data is saved to the
Memory Card as a CSV file. Once the data has been saved, the system automatically turns OFF
$SB38.
The data is output to a file called Operat.csv in the Memory Card \log\ directory.
Operat_yymmdd_hhmmss.CSV
Fixed text string
Date file was saved
(year, month, day)
Time file was saved
(hour, minutes, seconds)
If there is no accumulated data log, only the title line will be output. ($SB33 will turn OFF and $SB47
will not turn ON.)
If an error occurs during the save operation (e.g., the Memory Card is not in place, there is insufficient
free disk space, or the Memory Card is damaged), $SB38 will turn OFF and $SB47 will turn ON.
No error message will appear on the screen, however, when an error occurs.
If $SB37 and $SB38 turn ON simultaneously, initialization will be executed first. For this reason, no
Operat.CSV file will be created.

♦
For project versions earlier than version 8.0, operation log data is output to a file called Operat.CSV
in the Memory Card\log\directory. The file name is always the same, so any previously output data
is overwritten.
Operation Log Control ($SB39, $SB40, and $SB41)
Bits $SB39 to $SB41 control the operation log. $SB39 controls functional object operations and
changes to communications addresses. $SB40 controls screen switching operations, and $SB41 con-
trols macro operations.
When each of the bits $SB39 to $SB41 turn ON, the relevant logging operation starts. The logging op-
eration is ended when the bits turn OFF.

Any instance of screen switching executed while $SB40 is ON will be logged.
Initialize Error Log ($SB42)
$SB42 initializes the error log data. When $SB42 is turned ON, the error log information recorded in
the PT is initialized. Once the initialization has been completed, the system automatically turns OFF
$SB42.
