 Time domains comprise blocks which run with the same periodicity. Each time such a time domain executes everyone of its blocks runs in a predetermined way. A control system may have one or several time domains running with different periods.

+===== Transitions from one Time Domain to another =====
+The control system offers a special transition block whenever a signal crosses from one time domain to another. Such a transition block has two different manifestations depending on the two time domains involved.
+  * Signal passing from slow time domain to fast time domain: In this case the transition block does interpolate the signal in the fast time domain.
+  * Signal passing from fast time domain to slow time domain: The transition block filters the incoming signal according to a desired timestamp.
+For further details of the transition block, see [[eeros_architecture:control_system:available_blocks:transition|]].
