«Reset Value»
Defines the value after a reset event. Common parameter type. Enter a numerical value, a
variable, or an expression in the text box.
«Trigger Setting»
Defines the kind of integration after a reset event. Each value 0 means '1' in the table
above. Common parameter type. Enter a numerical value, a variable, or an expression in the
text box.
� «Sample Time»
Enter 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.

Sample and Hold Element
>>Basics>Blocks>Discrete Blocks
The block samples the input signal and holds this value constant up to the next sampling moment
(discretization by time). The sampling period is specified as a number of samples.
