PASSWORD SECURITY
612
Invalid Password Attempts
Range: 2 to 5 in steps of 1
Default: 3
This setting specifies the number of times an incorrect password can be entered within a
three-minute time span before lockout occurs and applies to both the setting and
command passwords.
When lockout occurs for the command password level, the
communication operands are set to "On." These operands are

returned to the "Off" state upon expiration of the lockout. Likewise, when lockout occurs
for the setting password level, the
communication operands are set to "On." These operands are also returned to the "Off"
state upon expiration of the lockout.
Password Lockout Duration
Range: 5 to 60 minutes in steps of 1
Default: 5 minutes
This setting specifies the time that the D90
after the number of invalid password entries specified by the
setting has occurred.
Password Access Events
Range: Enabled, Disabled
Default: Disabled
This setting enables and disables the logging of password access supervision events in
the sequence of events recorder.
The following dual-permission security access settings prevent unauthorized or
unintended upload of settings to a device through the local or remote interfaces.
Local Setting Authorization
Range: selected operands (see description below)
Default: ON
This setting is used for local (front panel USB and RS485 interface) setting access
supervision. Valid operand values are either "ON" (default) or any physical contact input
value.
If this setting is "ON," then local setting access functions as normal; that is, a local setting
password is required. If this setting value is any contact input operand, then the operand
must be asserted (set as on) prior to providing the local setting password to gain setting
access.
Remote Setting Authorization
Range: any communications operand or shared operand
Default: ON
This setting is used for remote (Ethernet and RS485) setting access supervision.
If this setting is "ON" (the default setting), then remote setting access functions as
normal; that is, a remote password is required). If this setting is "OFF," then remote
setting access is blocked even if the correct remote setting password is provided. If this
setting is any other operand, then the operand must be asserted (set as on) prior to
providing the remote setting password to gain setting access.
