The block implements the function of the controlled key according to the following algorithm:

where x(t) is the vector of the input signals; y(t) is the vector of the output signals; T0 is the vector of the "closing" times of the corresponding inputs and outputs; y0 is the vector of the output signals of the block at times less than T0.

where x(t) is the vector of the input signals; y(t) is the vector of the output signals; T0 is the vector of the "closing" times of the corresponding inputs and outputs; y0 is the vector of the output signals of the block at times less than T0.
Inputs
- input - block input, x.
Outputs
- output - block output, y.
Properties
- Time setpoint – vector T0.
- Subthreshold value at the output – vector y0.
Parameters
- Level - the current position of the key.
Note:
- By default, the block generates a scalar output signal.
- Named properties can be set as local model variables (submodels) in a programming language script, as global project signals using the Tools → Signals main menu item, or as external project signals using an attachable signal database.
