Memory area available for user files in ic92xx

Summary of temporary and permanent locations on the controller that are made available to the user.

For files that needs to be written or read frequently [RAMdisk] :

These files will be lost on power cycle of the controller

Path : /media/ramdisk

For files that are written or read infrequently and need to be stored permanently [FLASH]:

It is not recommended to constantly read/write from/to flash memory on any controller because it will affect the flash memory performance. Permanent memory interactions have a fixed number of cycles. We recommend writing to ramdisk which is temporary. If there are files that need to be written only once , like a one time cam file, it can be written to flash.

Path: /opt/plcnext/user/data
