IO Data Sink

Record, output, or terminate input message

  • Library:
  • SoC Blockset / I/O Data Source and Sink

  • IO Data Sink block

Description

The IO Data Sink block records, outputs, or terminates the received input message signal. The input of this block connects to the output of the TCP Write, UDP Write, or Register Write block. This block enables you to save the received input data to a file that you can play back using the IO Data Source block in the model. You can also terminate the signal or output the signals through an output port which can be fed as an input to IO Data Source block.

Ports

Input

expand all

This port receives the data vector from the msg port of the processor io blocks, which includes Stream WriteTCP Write, UDP Write, or Register Write blocks.

Data Types: SoCData

Output

expand all

Output data, returned as a numeric vector. The block converts the received input message into a data signal.

Dependencies

To enable this port, set the Output parameter to To output port.

Data Types: uint32 | double | single | int8 | uint8 | int16 | uint16 | int32 | int64 | uint64 | Boolean | fixedpoint

Length of output data, returned as a nonnegative scalar.

Dependencies

To enable this port, set the Output parameter to To output port.

Data Types: double

Control signal that indicates whether the output data is valid. When this value is 1 (true), the value on the output data port is valid.

Dependencies

To enable this port, set the Output parameter to To output port.

Data Types: Boolean

When done is 1, the block has no more stream output data to return in the data port. When done is 0, the block has more stream data to return in the data port.

Dependencies

To enable this port, set the Device type parameter to Stream.

Data Types: Boolean

This port sends a task event signal that triggers the Task Manager block to execute the associated event-driven task.

Dependencies

To enable this port, set the Show port parameter to Data and Event.

Data Types: rteEvent

Parameters

expand all

Set the sink of output data from the block by selecting one of these values.

  • To file — Save output data to a file.

  • To output port — Output data and signals by using output ports on the block.

  • To terminator — Terminate the received input signal.

Select a device type to enable the corresponding input data port.

  • UDP — Enable the msg input port to receive UDP data as message from a msg port of UDP Write block.

  • TCP — Enable the msg input port to receive TCP data as message from a msg port of TCP Write block.

  • Register — Enable the msg input port to receive Register data as message from a msg port of Register Write block.

  • Stream — Enable the msg input port to receive Stream data as message from a msg port of Stream Write block.

Select one of these values to enable the corresponding output ports towards the writing source.

  • Data — Enable only the msg input port.

  • Data and event — Enable the msg input and event output ports.

Specify the number of data elements to store in the data queue. This parameter must match the Number of buffers parameter specified in the Memory Channel block.

Dependencies

To enable this parameter, set the Device type parameter to Stream.

Specify a discrete time interval, in seconds, at which the block outputs data. The default value -1 inherits the sample time from the solver used for simulating the model.

Specify the full path to where you want to save the file on the host PC. This block saves the output data as a TGZ file. You can import this file into the model by using the IO Data Source block.

Dependencies

To enable this parameter, set the Output parameter to To file.

Specify a name for the output data source in which to save the data in the dataset file.

Dependencies

To enable this parameter, set the Output parameter to To file.

Select the data type of the output data. This value must match the data type of the input data.

Dependencies

To enable this parameter, set the Output parameter to To file or To output port.
