Volatile Disk (GS200RAM)

The GS200RAM is a volatile disk. When you turn the GS200 on, this disk is automatically formatted. During storage, the result file (Result.csv) is created on this disk. This disk is normally used to transfer files that the GS200 generates to your PC. However, a system file is transferred from your PC to this disk when you update the system firmware. For details, see Yokogawa GS200 manual section 14.5, “Updating the System Firmware.”
