Counter

R2026b

Discrete- or continuous-time counter

• 

Counter 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:
Simscape / Electrical / Control / General Control

Description

The Counter block implements an incremental counter in either discrete or continuous time. The counter increments in response to one of these criteria:

• Up — The input goes up.

  

• Down — The input goes down.

  

• Up-Down — The input goes up or down.

  

Ports

Output

T — Counter value

scalar

Counter value.

Data Types: single | double

Parameters

Counter type — Counter strategy

Up (default) | Down | Up-Down

Counter type.

Output range — Range

[0 1] (default) | [-1 1]

Range for the output.

Timer period (s) — Period

0.001 (default) | positive scalar

Timer period, in s.

Phase delay (s) — Delay

0 (default) | 0 or positive scalar

Phase delay, in s. Add a phase delay to change the initial state of the counter.

Sample time — Block sample time

0.0001 (default) | 0 or positive scalar

Time between consecutive block executions. During execution, the block produces outputs and, if appropriate, updates its internal state. For more information, see What Is Sample Time? and Specify Sample Time.

For discrete-time simulation, set the sample time to a positive scalar. For continuous-time simulation, set the sample time to 0.

Programmatic Use: Add Block

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

"ee_sl_lib/General Control/Counter"

Example: add_block("ee_sl_lib/General Control/Counter","myModel/myBlock",MakeNameUnique="on")
