Practical Installation Case

During a scheduled upgrade of a Yokogawa engineering station, the AIP444-S1 Hard Disk Module replaced an aging storage device nearing the end of its service life.

After installation, the workstation booted successfully, but engineering projects were unavailable because the project database had not yet been restored.

Following restoration from the latest verified backup:

• The operating system loaded normally.
• Engineering projects became fully accessible.
• Historical process records were recovered.
• The workstation returned to normal operation without data loss.
