Entity Terminator block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
SimEvents

Description

The Entity Terminator block accepts and destroys entities. Use this block to represent the entity departure from the model.

To customize actions when entities enter, use MATLAB^® code in the Entry action field of the Event actions tab. See Events and Event Actions, for more information.

Examples

Generating and Initializing Entities

Different ways to generate and initialize entities and their attribute values.

• Open Model

M/M/1 Queuing System

An M/M/1 queue is a queuing system that has a Poisson arrival process, an exponential service time distribution, and one server. This example models an M/M/1 queuing system with a single traffic source and infinite storage capacity.

Ports

Input

Port_1 — Input entity

scalar | vector | matrix

Input entity port for entities entering the terminator.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | enumerated | bus | fixed point

Output

Port_a — Number of entities arrived

scalar

Number of entities that have arrived at the block.

Dependencies

To enable this port, click the Statistics tab and select the box labeled Number of entities arrived, a.

Data Types: double

Parameters

Event action — Specify the behavior of the entity in certain events

Entry

Specify the behavior of the entity in certain events. Define the behavior in the Event action parameter. The Entry action is called just after the entity entry to the block.

Programmatic Use

Block Parameter: EntryAction

Type: character vector

Values: MATLAB code

Default: ''

Number of entities arrived, a — Outputs the number of entities that have arrived at the block

off (default) | on

Number of entities that have arrived at the block.

Programmatic Use

Block Parameter: NumberEntitiesArrived

Type: character vector

Values: 'on' | 'off'

Default: 'off'

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"sldelib/Entity Terminator"

Example: add_block("sldelib/Entity Terminator","myModel/myBlock",MakeNameUnique="on")
