Emerson 20/20 service manual Data Backup, Save / Load

Section 20 • Data Backup

Overview

The database backup screen provides the operator a way to extract information out of the Vission 20/20 for backup purposes or diagnostics, see Figure 20-1 Data Backup Screen. Through this screen, the operator can download all the Setpoint Databases, Maintenance Logs, Event Lists, Freeze Data, Trend Data and Compressor Run Hours to a portable USB flash drive. That information can then be uploaded back to the Vission 20/20 in the case of data corruption or to update the Vission program. Built in migrate function examines the previous setpoint databases, compares it with newer program setpoint da- tabase, and moves the old information into the new pro- gram. In addition, this screen also allows the operator to reset all values to the factory defaults.

All of the information saved to the USB flash drive is open information. Meaning none of the information is encrypted and the operator is free to examine it. The log files are all saved as simple ASCII text and the databases can be examined with SQLite.

Refresh:

•The Refresh button is used to initiate a scan of the USB ports and list any devices found in the “Available Devices” window.

Save / Load

Save / Load section is where the operator can either save the Vission 20/20 setpoints and log information to a USB flash drive or load from a USB flash drive back to the Vission 20/20.

Save:

•Selecting save allows the operator to save the Vission 20/20 data to a USB flash drive using the information provided further down the screen. The bottom but- ton will be labeled “Save” when this is selected.
