Common Block Parameters

Description

Values

Name of the library block

string

that the block is linked to (for

blocks with a disabled link).

String format specified for

string

block annotations in the Block

Parameters dialog box.

Block background color.

RGB value array string |

[r,g,b,a] where r, g, b,

and a are the red, green, blue,

and alpha values of the color

normalized to the range 0.0

to 1.0. The alpha value is

ignored.

Block description shown in the

string

Block Properties dialog box.

Block type (read only).

(Ctrl+C)

Function called when

string

close_system is run on

block.

time]

Function called when block is

string

copied.

For internal use.

Description

Values

Function called when block

MATLAB expression

is deleted. If a block

is graphically deleted,

you can still undo the

operation and call the block’s

UndoDeleteFcn. In addition,

for graphically deleted blocks,

the block’s DestroyFcn is still

called when the model is closed

or any subsystem containing

the block is destroyed using

delete_block.

Function called when block

MATLAB expression

is destroyed. If you run the

delete_block command

for a block, it first calls the

block’sDeleteFcn, then calls

the DestroyFcn for that block;

no undo is possible. The

DestroyFcn is also called

when you close the model

or invoke delete_block on

a subsystem containing the

block.

Description of block. Set by

text and tokens

the Description field in the

General pane of the Block

Properties dialog box.

For internal use.

{'off'} | 'on'

Description

Values

Enable a block to support

{'off'} | 'on'

uploading of signal data in

external mode (for example,

with a scope block).

Enable a block to act as the

{'off'} | 'on'

trigger block for external mode

signal uploading.

Enable a block to upload signal

{'none'} | 'log' |

data in external mode when

'monitor'

the Select all check box on the

External Signal & Triggering

dialog box is not selected. A

value of log indicates the

block uploads signals. A value

of none indicates the block

does not upload signals. The

value monitor is currently

not in use. If the Select all

check box on the External

Signal & Triggering dialog box

is selected, it overrides this

parameter setting.

Font angle.

'normal' | 'italic' |

'oblique' | {'auto'}

Font.

string

Font size. A value of -1

real {'-1'}

specifies that this block

inherits the font size specified

by the DefaultBlockFontSize

model parameter.

Font weight.

'light' | 'normal'

| 'demi' | 'bold' |

{'auto'}

Description

Values

Foreground color of block’s

string {'black'} |

icon.

[r,g,b,a] where r, g,

b, and a are the red, green,

blue, and alpha values of the

color normalized to the range

0.0 to 1.0. The alpha value is

ignored.

Block handle.

real

For internal use.

Initialization function for a

MATLAB expression

masked block. Created on

the Callbacks pane of the

Model Properties dialog box.

See “Create Model Callback

Functions” in the Using

Simulink documentation for

further information.

Names of input signals.

cell array

list

Signal & Scope Manager type.

For internal use.

Handles of lines connected to

struct

Link status of block.

{'none'} | 'resolved' |

Updates out-of-date reference

'unresolved' | 'implicit'

blocks when queried using

| 'inactive' | 'restore'

get_param.

| 'propagate'

Function called when block is

MATLAB expression

loaded.

For internal use.

Description

Values

Function called when model

MATLAB expression

is closed. The ModelCloseFcn

is called prior to the block’s

DeleteFcn and DestroyFcn

callbacks, if either are set.

For internal use.

Function called when block is

MATLAB expression

moved.

Block name.

string

Function called when block

MATLAB expression

name is changed.

Position of block name.

{'normal'} | 'alternate'

Names/attributes of block’s

opens.

Where block faces.

{'right'} | 'left' | 'up'

Names of output signals.

cell array

Name of the system that owns

string {'untitled'}

Description

Values

The value of this parameter

structure array

is an array of structures, each

of which describes one of the

block’s input or output ports.

Each port structure has the

following fields:

• Type

Specifies the port’s type

and/or number. The value

of this field can be:

- n, where n is the number

of the port for data ports

- 'enable' if the port is an

enable port

- 'trigger' if the port is a

trigger port

- 'state' for state ports

- 'ifaction' for action

ports

- 'LConn#' for a left

connection port where #

is the port’s number

- 'RConn#' for a right

connection port where #

is the port’s number

• Position

The value of this field is

a two-element vector, [x

y], that specifies the port’s

position.

Description

Values

• SrcBlock

Handle of the block

connected to this port.

This field is null for output

ports.

• SrcPort

Number of the port

connected to this port.

This field is null for output

ports.

• DstBlock

Handle of the block to which

this port is connected. This

field is null for input ports.

• DstPort

Number of the port to which

this port is connected. This

field is null for input ports.

The value of this parameter

structure array

is a structure that specifies

the handles of the block’s

ports. The structure has the

following fields:

• Inport

Handles of the block’s input

ports.

• Outport

Handles of the block’s

output ports.

Description

Values

The value of this parameter

vector

is a vector that specifies the

numbers of each kind of port.

The order of the vector’s

elements corresponds to the

following port types:

• Inport

• Outport

• Enable

Description

block is saved. Created on

the Callbacks pane of the

Model Properties dialog box.
