Description

[Picture]

Continuous inputs are used to feed continuous signals from Simulink into a PLECS circuit or from a circuit into a subcircuit. If you copy an input block into a schematic an input terminal will be created on the corresponding subsystem block. The name of the input block will appear as the terminal label. If you choose to hide the block name by unselecting the show button in the dialog box the terminal label will also disappear. The Continuous Input block can be distinguished from the Gate Input block by the green instead of a brown output terminal.

Input Blocks in a Top-Level Circuit

If an input block for a continuous or gate signal is placed in a top-level circuit a unique number is assigned to the block. In Simulink, the relative position of the corresponding input terminals is determined by the order of block numbers. You may change the block number in order to change the relative terminal position.

Input Blocks in a Subcircuit

If placed in a subcircuit the inputs are not identified by numbers since the terminals of the subcircuit can be freely positioned. Which terminal corresponds to which input block can only be seen from the block name. In order to move an unconnected terminal with the mouse around the edges of a subsystem hold down the Shift key or use the middle mouse button.

Parameters and Dialog Box

Width
The width of the input signal. The default is 1.
Port number
The terminal number of the input block. This parameter appears only if the block is placed in a top-level circuit.
