column below can be individually selected from the subordinate Specific 
data type 
menu. 
Note that data type information can also be displayed in a model by selecting 
Port data types from the model window’s Format menu.

Sample mode
Checks whether the signal is discrete-time or continuous-time. (Note that 
when 
Sample time colors is selected from the Format menu, Simulink 
displays continuous-time signal lines in black or grey and discrete-time 
signal lines in colors corresponding to the relative rate. When a Probe block 
with 
Probe sample time enabled is attached to a continuous-time signal, the 
block icon displays the string 
Ts:[0 x], where x is the sample time offset. 
When a Probe block is attached to a discrete-time signal, the block icon 
displays the string 
Ts:[t 0] for a sample-based signal or Tf:[t 0] for a 
frame-based signal, where 
t is the nonzero sample period or frame period, 
respectively. Frame-based signals are almost always discrete-time.)
