4.8 File Transmission at Boot Function
By using the file transmission at boot function, operations such as the following can be performed when Multiple CPU system
power supply is turned ON, or reset.
• Copy the parameters and programs on the standard ROM to the SD memory card.
• Copy the parameters and programs on the SD memory card to the standard ROM and startup Motion CPU.
Set the operation of the file transmission at boot function in [Motion CPU Common Parameter] [Basic Setting] "File
Transmission Setting during Booting".
When the Multiple CPU system power supply is turned ON, file transmission at boot is executed as per the "File Transmission
Setting during Booting".
File transmission at boot files
In file transmission at boot, the boot operation file, and boot log file are saved to the "$MMTPRJ$" folder of the SD memory
card root folder.
Functions of the boot operation file
The operations specified by the boot operation file are shown below.
: Can be specified, : Can not specified (specified as blank)
CAUTION
• Depending on the contents of the boot operation file, Motion CPU control can be changed just by installing the SD memory card. To avoid unexpected
operations, check the data on the SD memory card before installing.
• Depending on the boot operation file, control data in the Motion CPU can be taken out from the CPU. To avoid the unauthorized reading/taking of data, use
the security function. (Page 294 Security Function)
Item File name Operation File saving
Boot operation file boot01.csv Executes file transmission at boot after Multiple CPU system power supply is turned
ON.
User saves the file in the
"$MMTPRJ$" folder.
Boot log file bootlog.txt Stores the list of files that are read at the initial processing after Multiple CPU
system power supply is turned ON, and the processing details of file transmission at
boot. The contents are overwritten each time the Multiple CPU system power supply
is turned ON.
System saves the file in the
