SETTINGS
PRODUCT SETUP
SECURITY
The C30 supports password entry from a local or remote connection.
Local access is defined as access to settings or commands via the faceplate. This includes both keypad entry and the
RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes
both Ethernet and RS485 connections. Any change to the local or remote password enables this functionality.
ACCESS LEVEL
— The "Restricted" option means that settings and commands can be accessed, but there is no access to
factory configuration. Access automatically reverts to the Restricted level according to the access level timeout setting
values. The access level is set to Restricted when control power is cycled.
The "Factory Service" level is not available and intended for factory use only.
There are two user security access levels, setting and command, for which you can set a password for each. Use of a
password for each level controls whether users can enter commands or change settings. Another option is to specify
setting and/or command access for individual user accounts.
•
Setting
— Allows the user to make any changes to any of the setting values:
–
Changing any setting
–
Test mode operation
•
Command
— Restricts the user from making any settings changes, but allows the user to perform the following
operations:
–
Changing the state of virtual inputs
–
Clearing the event records
–
Clearing the oscillography records
–
Changing the date and time
–
Clearing the data logger
–
Clearing the user-programmable pushbutton states
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 C30, the remote password must be used. If the
connection is to the RS232 port of the faceplate, 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
