Web graphs

Configure a web site

To be able to open the varoius process graphs in a system it is suitable to have web page
with a menu to the left and actual graph to the right. With some configuration you can generate
such a page from 'Generate web' in the menu.

This is how the configuration is done:
Create a WebHandler object under the node object in the node hierarchy. The WebHandler object
will cause the start of a server process that supplies the graphs with the dynamic information
from the realtime database. In the object you also state if you should be able to log in as a
ProviewR user. Under the WebHandler object you create a WebGraph object for each graph that is
to be opened from the menu.
Under the WebHandler object, you can also create WebLink objects. Each WebLink object give rise
to a menu entry that is connected to an URL, e.g. documents for working instructions, function
specifications etc.

All files required for the web site are gathered in the directory $pwrp_web. By copying these
files, together with the files $pwr_lib/pwr_rt_client and $pwr_lib/pwr_jop.jar, to a suitable
directory in the web server, the operator station is available on the net.
