This instruction is used to apply three different commands to the File System. The first is format. This will remove all files or folders on the RAM file system. The format option is not valid for the SD cad System. Dismount prepares the SD card for extraction. It closes all the files, ends outstanding file operation and the memory light on the BRX CPU will turn red. The mount prepares the SD card File system for use. With the card installed, and the mount function triggered the memory light on the BRX CPU will turn green. This instruction can be used in a Task or Program but cannot be used in Subroutines or Interrupt service routines. Now only BRX PLCs have the SD Card File System, but all Do-mores have a useable RAM File System if they have above version 2.0 firmware.
