2.5 Common Tasks Performed via the Local Keypad and/or Web Interface
Refer also to “Chapter 3. Local Display Menus” and “Chapter 4. WEB Interface Menus”.

2.5.1 Backing Up the Configuration

A file named “SettingParam.run” is automatically created/appended by the Controller whenever a User
makes changes to any parameter settings via the LCD or WEB interface. This file can be saved to your
computer so you can restore any custom settings you may have made.
Prior to changing settings, ensure the current “SettingParam.run” file is backed up. After making changes,
create a new backup file. Note that you may change the name of a “SettingParam.run” file to differentiate
it from other files saved. The new name can use alpha and numeric characters preceding the original
“SettingParam.run” name (the end of the new file name must always be “SettingParam.run”; for example,
an acceptable filename would be “seville4SettingParam.run”).
Local Menu Navigation: none.
WEB Menu Navigation: See also “4.7.9. Retrieve ‘SettingParam.run’ File Sub-Menu”.
