About Saving Areas

The following saving areas can be used with this device.

Saving area		Description
Controller	Flash memory	Settings data is saved in this area.Data is held even after the power is turned off.
	On-board memory	This is the area where images are temporarily stored when logging images using the logging function. This memory is a ring memory, and images will be overwritten starting with the oldest image if the maximum number of save images is exceeded.
	RAM disk	Can be used as a temporary file save destination.Data is cleared if the controller power is turned off. The RAMDisk data can be sent to or received from external devices using the FTP function.
USB memory		Used to back up settings data as a precaution, to copy settings data to another controller, and to load data to a PC.To keep data, save to the USB memory before turning off power to the controller.

Important

During data transfer, do not turn off the power.

When a message indicating that processing such as saving or loading is in progress is displayed, do not restart the controller or turn off the power. Data will be corrupted and the system will not work properly at the next startup.
Do not remove USB memory devices during saving or loading.Operation of the controller may damage data or the USB memory.
Do not change the extension of saved files. If changed, the file cannot be loaded as the setting data. In addition, if setting data in which the extension was changed is loaded, the system may not work properly later.
Depending on the settings, saving may fail due to insufficient USB memory capacity.If saving fails and the error message "Please check." appears, check to see if there is unnecessary data in the USB memory and save after this data has been deleted.
