1.2.1 Session in a single-TMR environment
In order to fully understand how a Remote Control session works, it is important

Remote Control, starting with the most simple scenario.
Data flow for single-TMR session
Figure 1-2 shows in detail how a Remote Control session works in a single-TMR

The legend used in this diagram is explained as follows:
