Settings
The Settings section contains communication parameters specific to the CDP
protocol. The TimeOut element defines the timeout for not received messages.
This element identifies the time until the connection is considered broken and is
only needed for bidirectional communication. The MaxLost attribute defines the
maximum number of not acknowledged or lost messages allowed. The DryRun
element identifies, if the acknowledgement of messages is supervised and can be
used to setup an unidirectional communication.
Element

DryRun
If the element DryRun in the Description.xml is set to FALSE, communication
supervision is established on the protocol level of the Robot Reference Interface,
using the settings for TimeOut and MaxLost. This supervision requires that each
message that is sent out from the robot controller is answered by the connected
device. The supervision generates a communication error, if the maximum response
time or the maximum number of lost packages is exceeded. Each sent out message
has an ID, which needs to be used for the ID in the reply too, to identify the reply
message and to detect which packages have been lost. See also the example in
