4. Remote Communications
Webserver
4.1.1. Main page
The Web server can be used by entering the IP address of the device into a browser address bar. This allows
the user control of various settings within the device and to read the devices current reading. Along the top
are a series of tabs to allow the user to switch to various sections of device control. Also along the side is the
device serial number and controls to start streaming communications, note for TCP streaming to work a TCP
connection on port 101 must be pre-established (the unit does not data stream over the HTTP port (80)).
4.1.2. Live data
The live data page is the first page the user will see when the web server is loaded up. The main feature of this
page is the live data output from the device, but it also has the capabilities to rezero the channel, to change
the setpoint value and to set the setpoint valve position. Note: The setpoint is set in engineering units as
configured by the range setting and cannot be set to more than this range configuration.
The units string and device range can be changed from the Channel cfg page.
4.1.3. Channel Configuration page
The channel configuration contains channel setup options.
· Units string allows the user to change the units of the channel.
· Range is the Engineering unit conversion of the Voltage output from the transducer (e.g. in the image above
10 Volts = 100 mbar).
· The number of decimal places set for the range dictates its display precision
· Fullscale is the maximum Voltage output of the transducer.
· Source is where the setpoint is referenced from, Internal will output the number entered as the setpoint
value and Slave will output a percentage of the external input.
· Init value is the value to which the setpoint will be set to at start-up.
· Init mode is the valve position, auto is the normal setpoint mode, Open will set maximum range voltage
output and closed sets minimum range
