When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the C70, the remote password must be used. If the
connection is to the RS232 port of the front panel, the local password must be used.
The local setting and command sessions are initiated by the user through the front panel display and are disabled either by
the user or by timeout (via the setting and command level access timeout settings). The remote setting and command
sessions are initiated by the user through the EnerVista software and are disabled either by the user or by timeout.
The state of the session (local or remote, setting or command) determines the state of the following FlexLogic operands:
• ACCESS LOC SETG OFF — Asserted when local setting access is disabled
• ACCESS LOC SETG ON — Asserted when local setting access is enabled
• ACCESS LOC CMND OFF — Asserted when local command access is disabled
• ACCESS LOC CMND ON — Asserted when local command access is enabled
• ACCESS REM SETG OFF — Asserted when remote setting access is disabled
• ACCESS REM SETG ON — Asserted when remote setting access is enabled
• ACCESS REM CMND OFF — Asserted when remote command access is disabled
• ACCESS REM CMND ON — Asserted when remote command access is enabled
PASSWORD ACCESS EVENTS — This setting allows recording of password access events in the event recorder.

SETTINGS  PRODUCT SETUP  SECURITY  CHANGE LOCAL PASSWORDS
As outlined in the previous section, there are two user security access levels, setting and command. Use of a password for
each level controls whether users can enter commands or change settings.
Proper password codes are required to enable each access level. When a
CHANGE COMMAND PASSWORD or CHANGE
SETTING PASSWORD
setting is programmed to “Yes” via the front panel interface, the following message sequence is
invoked:
1. ENTER NEW PASSWORD: ____________.
2. VERIFY NEW PASSWORD: ____________.
3. NEW PASSWORD HAS BEEN STORED.
A command or setting write operation is required to update the state of the remote and local security operands
listed.
When a setting password or command password is set or updated, user access with a graphical front panel is
removed. Simply log in again on the graphical front panel.
When the setting password is set or updated, the graphical front panel Access Level displays as Command. This is
because the graphical front panel is a Modbus client and it does not have automatic access to the password
change.
