Local Operator Interface Password

A Local Operator Interface Password can be entered and enabled to prevent review and
modification of device configuration via the LOI. This does not prevent configuration from HART
or external keys (analog zero and span; Digital Zero Trim). The LOI password is a 4 digit code
that is to be set by the user. If the password is lost or forgotten the master password is "9307".
The LOI password can be configured and enabled/disabled by HART communication via a Field
Communicator, AMS Device Manager, or the LOI.
