Key-Lock Security
The front panel keyswitch on ControlWave provides
a high level of manual security by allowing three
modes of operation to restrict access ot on-line
functions.
In Run Mode, ControlWave will reject any attempt
to download or modify the running program, either
locally or over the network.
In Remote Mode, ControlWave will allow download-
ing and on-line program modication through the
network provided the security access requirements
have been met. Local download and on-line modi-
cation of the running program is prohibited.
In Local Mode, ControlWave will allow download
and on-line modication through either the network
connection or through a local serial communica-
tion port provided the security access requirements
have been met.
Multi-User Security Access
Security is an essential element of any open
system, particularly those with Internet access.
ControlWave employs a User Name/Password ac-
cess system protected by a 56-bit encryption tech-
nique through the TCP connection. There can be
up to thirty-two users who sign in using their name
and password. Both the name and the password
can be up to sixteen characters.
The security system provides for up to sixty-four
access rights to read and write data values and les
via FTP, access and congure historical and audit
data information, edit conguration, run internal
diagnostics, read and reset system status. It further
allows the programming software to read, write and
download the ControlWave.
The Secure Data Advantage
ControlWave sets a new standard for providing in-
telligent control at the point where control is needed.
Whether you need control on the plant oor or at a
remte site in the "middle of nowhere", ControlWave
is the solution for control, communication and
secure data to help you make the right operating
decisions.
ControlWave was designed to provide the optimum
level of data security using a distributed database
architecture. All data including time & date stamped
alarms, alarm limits, and historical data are stored
locally in each industrially rugged ControlWave,
thereby distributing your data integrity risk. To
rther ensure that the data is always current and
historically accurate, the historical data is stored
in non-volatile ash memory within ControlWave.
Historical data is even maintained during and after
program downloading.
When historical data is collected from ControlWave,
it is converted and appended to .CSV and/or ODBC
compliant databases but does not destroy the origi-
nal historical data stored in ControlWave, thus pro-
viding a exible and secure historical data system
that is clearly recognized as a benet to virtually
every industrial application.
The Bridge Between Systems
Continuing our tradition of introducing innovative
new solutions while maintaining compatibility with
existing systems, Emerson again provides a migra-
tion path for existing customers by bridging the new
ControlWave system with Network 3000 systems
already in place. The network bridge is enabled
by employing the open architecture technologies
afforded by TCP/IP and OPC in both networks.
TCP/IP allows seamless Ethernet connectivity to
both networks as well as the corporate Intranet so
both ControlWave and Network 3000 controllers can
reside and communicate on the same LAN. Em-
erson’s Bristol OpenBSI OPC Server facilitates the
merging of the two networks for technical, engineer-
ing and operator data access. The data source,
conguration and path are completely transparent to
the OPC client. Real-time data can also be passed
between the two communication networks, making
this a total Plant Automation Management Solution.
