OPC Clients
An OPC client can be used instead of the TrendServer software. It is a user software ap-
plication for realtime interface between servers and clients. Information from our comms
server, which is OPC compliant, uses an industry standard method of uniform data inter-
change. The OPC client can then export realtime communications to other applications, eg.
Microsoft™ Excel. OPC clients must be version 3 compatible.
For more information refer to Application Note 4 - OPC Access.
Web Browser
The Web Browse function can be enabled/disabled from the recorder. This allows you to
view the recorder information only. The web button can be password protected if passwords
are enabled. See “Web” on page 80. This is a firmware option that first needs to be acti-
vated in Options, see “Credits” on page 102. The Remote Viewer is a firmware option that
can be added to allow access to the recorder from a web page. The Remote viewer option
needs to be activated in the Firmware options screen, see “Credits” on page 102.
To access your recorder’s web page, type the device’s IP address in to a web browser such
as Internet Explorer. If Microsoft
WINS system (Windows Internet Name Service) is avail-
able then the device name can be used to search for the device web page. To find your re-
corder IP address see “TCP/IP” on page 73.
The recorder will automatically register a unique Network ID using the serial number. The
format is xs-nnnnnn, where nnnnnn is the serial number of the recorder. This allows you to
browse the recorder if you are using
DHCP (Dynamic Host Configuration Protocol).
On recorders with password security enabled further login will be required to access Full Re-
mote Control of the recorder from the web page and to enable a keyboard and mouse. For
users with Password functionality enabled Login is required. Enter your User name and
Password in the box to gain access to the recorder web page.
For Users without Password security just choose a language option to access the web page.
Select Remote Viewer to enable a desktop user interface. This will allow you to view and
control your recorder in realtime.
