Events Causing the Client to Send Data
• Modification of value of potentiometer (override)
• Modification of handwheel value
• Modification of key status of a key/button
• Data inquiry of server
With each event, the client sends the server a data package containing
the information about the type of event as well as the current data of
all operating elements. If the client produces several events one after
the other, and the server cannot process all of them at once, the server
will send one message containing all events.
Events of Server
By sending a package to the client, the server can set the current
value of the handwheel, or request the current values (position of
handwheel and override potentiometer, as well as state of keys). The
server can also read the current states of the values which can be
modified by the server.
