| Events are not handled like
Reports/Alarms/Trends where the handling is done by a server.
Events are handled by any computer where the [Events]Server=1
parameter is set in the Citect.ini file located on the computer.
This is done by selecting the "Enable Events on this computer"
checkbox during the CitectSCADA computer setup wizard.
When you prepare a project for web deployment through
CitectSCADA, the Citect.ini file created after the last execution
of computer setup wizard is copied to the
\User\<project>\WebDeploy\<project> directory. This is
then copied with the project files once the project is deployed to
the WebServer. If [Events]Server=1 is set in this Citect.ini file
then any computer running web client through Internet will handle
events. Care must be taken if for example the event runs cicode
that updates system tallies, then all web clients will be updating
the tallies. Any of the CitectSCADA servers (IO/Report/Alarm/Trend)
could also be handling events if set.
If you would like events to be handled centrally by one computer
then do not enable events for the web client, i.e. run computer
setup with events not enabled before deploying. Instead use the I/O
server to handle the events, this will have a different Citect.ini
to the deployed version.
