General mechanism
In contrast to Version V2.x the remote visualization clients are nothing else but
interpreters of
draw commands. Independent of its type (web, target, HMI) each
client will get the same instructions, so that the resulting visualizations will all be the
same.

As a consequence the related visualization application has to be downloaded to the
PLC, which might cause trouble for small PLCs. To overcome this problem a data server
is integrated into the runtime system to provide the necessary data for the
visualization application.
