Fieldbus Gateway Manager’s web server can be used to expose various data via the Fieldbus
Gateway’s Ethernet port, allowing remote access to diagnostic information, or to the values
recorded by the Data Logger. The web server is configured by selecting the Web Server icon
from the main screen.

The web server has the following properties…
Under the Main tab:
• The Server State property is used to enable or disable the web server. If the
server is enabled, the Gateway will monitor port 80 for incoming requests, and
will fulfill the requests as required. If the server is disabled, connections to this
port will be refused. Remember that in order for the server to operate, the
Gateway’s Ethernet port must have been enabled via the Communications
window.
• The Listen on Port property indicates the TCP port number the web server will
listen on. Port 80 is the standard http port for web browsing and will most likely
suit your application.
• The Title property is used to provide the title to be shown on the web server
menu. This title can be used to differentiate between several terminals on a
network, thereby ensuring that the correct terminal is being accessed.
• The Data Log Access property is used to enable or disable web access to the files
created by the Data Logger. Obviously, this facility must be enabled if the
WebSync utility is to be used to copy the log files to a PC.
• The Remote Viewing property is used to enable or disable a facility by which a
web browser can be used to view the current contents of the virtual HMI’s
display. This facility is very useful when remotely diagnosing problems that an
operator may be having with the Fieldbus Gateway or the machine it controls.
