Connecting Blocks in a Model
Before you connect a Gauges Blockset block with other blocks,
you should know whether it is meant to be an output device (with an
input connection), or a pass-through device (with an input and output
connection). Gauges Blockset blocks cannot serve as input devices
(with only an output connection). Gauges Blockset blocks
initially appear with both an inport and an outport, but unused ports
disappear when you start the simulation or update the block diagram.
To determine whether a Gauges Blockset block is meant to
be used as an output or pass-through device, right-click the block
and select the Block Parameters option.
Note
If you customized the generic ActiveX Control block to accommodate
your own control, then another way to display the custom block's Block
Parameters dialog box is to double-click the border of the block. |
In the Block
Parameters dialog box, the Connections field
determines the type of connection the block currently uses:
Input indicates that the
block is a sink; that is, it has an inport and receives a signal.
The Input property parameter indicates the block's
property whose value is changed by the input.
Both indicates that the
block has an inport and an outport. The values at both ports are the
same. That is, the block becomes a unity function.
Neither indicates that
the block has neither an inport nor an outport.
To specify a connection different from the block's default setup,
change the block's Connection setting and make
sure that the Input property field is filled
in with the appropriate property name. See Block Parameters for the ActiveX Control Block for information
about the other fields and check boxes. You can also use the Help button
to find out about other parameters.
