Two-point Element with Hysteresis
>>Basics>Blocks>Signal Processing
The block represents a two-point element with hysteresis. The component cannot be used
with AC and DC simulation.
yk ( ) = A1, if x( k)
< T1
yk ( ) = A1, if x( k)
< T2 and A( k – 1)
= A1
yk ( ) = A2, if x( k)
> T2
yk ( ) = A2, if x( k)
> T1 and A( k – 1)
= A2
Dialog Settings
«Threshold 1»«Threshold 2»
Define the threshold T1 and T2 of the Two-Point Element. Common parameter types. Enter a
numerical value, a variable, or an expression in the text box.
«Value A1»«Value A2»
Define the amplitude left (A1) from the threshold T1 and right (A2) from the threshold T2.
Common parameter types. Enter a numerical value, a variable, or an expression in the text
box.
� «Sample Time»
Select «System» for simulator-defined variable sample time. Select «Value» to define a numerical
value, a variable, or an expression in the text box or use the pin to connect a quantity.
Please note: The sample time must be a positive value.
� � «Use Pin»
If the box is checked, the sample time is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
«Input Signal»
Enter a quantity name used in your model sheet in the text box to define the input signal
(RLOAD.I, STEP.VAL, STATE.ST, VAR) or use the pin to connect a quantity. Please note: You
cannot use conservative nodes from circuits as input signal (N0002, GND).
� � «Use Pin»
If the box is checked, the input signal is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
