# Sample time (-1 for inherited) — sampling period
Details
The time between consecutive runs of the block.
During a run, the block produces output data and, if necessary, updates its internal state.
-
For legacy discrete-time operation, set the value to
-1. -
For discrete-time operation, set to a positive integer.
-
For continuous time operation, set the value to
0.
If this unit is in a masked subsystem or variant subsystem that supports switching between continuous and discrete operation, increase the value of this parameter to ensure correct switching between continuous and discrete implementations of the unit.
