9.6 Application Notes on the Target Visualization
Target visualizations differ from Web visualizations by being planned directly in
e!COCKPIT, in their reaction speed, in the fact that the visualization is provided
on the Visu Panel by means of a Webserver and in the communication options
(Modbus
®
and network variables). Therefore, a connection to other controllers is
possible.
Unlike the Web visualization, the target visualization is not generated on another
controller, but rather directly in the panel. What this means for the display is that
a website does not first need to be loaded from a controller and stored
temporarily in the RAM, but can rather be generated and displayed directly in the
panel. As a result, there are almost no delays when switching between different
pages. The entire performance of the visualization is significantly better.
Another great advantage is that the data volumes exchanged between the
controller and panel are significantly smaller.
Entire pages do not not need to be exchanged – only the corresponding
variables. The frequency of exchange can be configured. Depending on the
setting, it is possible for a variable to only be transferred if it has actually
changed. This significantly relieves the burden on the network and PFC, since
the data no longer needs to be provided via the Webserver and is instead
provided by the Visu Panel itself. Therefore, the control and visualization
functionality is independent of the network and PFC.
