More About Debug Log
SP5857-015: SD to SD (Any)
This SP copies the log on an SD card (the file that contains the information written directly from shared
memory) to a log specified by key number. The copy operation is executed in the log directory of the SD
card inserted in the same slot. (This function does not copy from one slot to another.)
Each SD card can hold up to 4 MB of file data. Unique file names are created for the data during the copy
operation to prevent overwriting files of the same name. This means that log data from more than one
machine can be copied onto the same SC card.
This command does not execute if there is no log on the HDD for the name of the specified key.
SP5857-016: Make HDD LogFile
This SP creates a 32 MB file to store a log on the HDD. However, this is not a completely empty file. The
created file will hold the number “2225” as the SCS key number and other non-volatile information.
Even if this SP is not executed, a file is created on the HDD when the first log is stored on the HDD, but this
operation takes time. This creates the possibility that the machine may be switched off and on before the
log can be created completely.
If you execute this SP to create the log file beforehand, this will greatly reduce the amount of time required
to acquire the log information and save onto the HDD. With the file already created on the HDD for the
log file, the data only needs to be recorded; a new log file does not require creation.
To create a new log file, execute SP5857-011 to delete the debug log data from the HDD and then execute
this SP (SP5857-016).
SP5857-017: Make SD Log File
This SP creates a 4 MB file to store a log on an SD card. However, this is not a completely empty file. The
created file will hold the number “2225” as the SCS key number and other non-volatile information.
Even if this SP is not executed, a file is created on the SD card when the first log is stored on the SD card,
but this operation takes time. This creates the possibility that the machine may be switched off and on before
the log can be created completely.
If you execute this SP to create the log file beforehand, this will greatly reduce the amount of time required
to acquire the log information and save onto the SD card. With the file already created on the SD card for
the log file, the data only needs to be recorded; a new log file does not require creation.
To create a new log file, execute SP5857-012 to delete the debug log data from the SD card and then
execute this SP (SP5857-017).
