Process data size
Size in bytes of the available process image
Process image mapping
Subdivision of a process image into independent parts and allocation of
these parts to specific slots for data transmission.
Q
Quality-of-Service (QoS)
Quality of a communication service from the view of the user. The user can
define his or her requirements regarding the communication service through
the QoS.
R
Real-time capability
Devices have real-time capability if their time behavior is deterministic; i.e.,
the observations of guaranteed maximum times in each operating condition
and the notification of timeouts as errors. For example, a device has real-
time capability with regard to data exchange if a maximum delay for the
transmission of data packets is never exceeded and errors or disturbances
that occur are reported to the next higher entity.
Real-time profile
The real-time profile is one of two profiles in the communication mode sup-
ported by the Bluetooth
plications.
Reconnection time
The "reconnection time" is the time interval in which a non-connected de-
vice attempts to establish connections to other devices.
