Instruction manual

XWEB 500 – rel.1.0 –
The first information about the archive shows into “Available Interval” the first and the last recording date,
while the “Select Interval” includes the period you can decided to show.
If necessary, modify the Select Interval period.
Longer is the time interval to show, longer the loading time needed to show the data graph.
For a first analysis select a time period not so wide but centred on the target of your interest, this ensure
higher graph precision. You can also act on “Graph Density” parameters to decide if you need all data
samples. This feature is very useful if you are connected via modem at a slow speed.
You have many rows: Analog Input – Setpoint – Digital Input – Output Status – Devices Staus - Alarm.
The number of the rows depends on the controller type.
For each of them you can graphs as many values as you want. The only limitation is 3 analog values and
2 digital ones.
For each selection is possible to decide the colour of the line that will be represented.
It is also possible to group the analogue inputs into a unique graph or to display them into separated
ones. For example if you want to display all data using only one graph, select for each value AG1 from
the roll-down menu, then in “Graph labels” write some words reminding you the meaning of the graphs.
On the other side if you want to display the values in different graphs, you have to chose AG1 for the first
values, AG2 for the second and AG3 for the third.
Remember that each graph can be renamed by the user with an appropriate name into the
corresponding “Graph Labels” situated into the low side of the page.
Before clicking the command “View” it is possible to define the graph density to decide the resolution of
the lines and recordings. Select the box “ Graph Density”.
Higher is the value of this parameter better will be the graph resolution, but longer the downloading time
from the XWEB 500.
Now Click on “View” to start the transferring process of data from the XWEB 500 to your PC.
The displaying structure is based on a Java Applet and the Java Virtual Machine program installed into
the remote PC that computes the data coming from the XWEB 500.
Depending on the Virtual Machine version installed a message to accept the term of use will appear
during the operation.
