Data Store Read

Read data from a data store.

Signals & Systems

Description

The Data Store Read block reads data from a named data store, passing the data as output. The data was previously initialized by a Data Store Memory block and (possibly) written to that data store by a Data Store Write block.

The data store from which the data is read is determined by the location of the Data Store Memory block that defines the data store. For more information, see Data Store Memory.

More than one Data Store Read block can read from the same data store.

Note    To avoid block output consistency errors, be careful not to set an execution priority on a Data Store Read block such that the block reads from the data store before the store is updated by any Data Store Write blocks that write to the store in the same time step.

Data Type Support

A Data Store Read block outputs a real signal of type double.

Parameters and Dialog Box

Data store name

The name of the data store from which this block reads data.

Sample time

The sample time, which controls when the block writes to the data store. The default, -1, indicates that the sample time is inherited.
