ThingSpeak Input

Scalar numeric data read from the ThingSpeak channel.

Example: 3.14159

Dependency

The setting of the Output data type parameter determines the port data type.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32

This parameter is read-only.

To select a channel, click the Configure channel parameters button. In the Network Services ThingSpeak dialog box, set the Channel ID parameter.

Programmatic Use

Block Parameter: DrvAddress

To configure the channel, click this button. A dialog box displays the channel parameter settings.

To accept your changes, click OK. To test your changes, click Test. To revert your settings to their previous values, click Revert. To exit the dialog box without changing the settings, click Cancel.

Programmatic Use

Block Parameter: DrvName

Block Parameter: DrvOptions

The default value is the standard address of the public ThingSpeak server.

Programmatic Use

Block Parameter: DrvName

Block Parameter: DrvOptions

Select a unique channel among the available channels.

You cannot read and write over the same ThingSpeak channel in the same model.

Programmatic Use

Block Parameter: DrvOptions

By default, this key is the API key for the channel on the public server, api.thingspeak.com.

Programmatic Use

Block Parameter: DrvOptions

Time between successive reads over the channel.

Programmatic Use

Block Parameter: DrvOptions

To access the web page for Channel number, click View channel web page.

Programmatic Use

Block Parameter: DrvOptions

Enter a value, in seconds, that represents how frequently you want the block to execute and interact with the I/O hardware. The block synchronizes your model with the real-time clock at this sample rate.

If you are using a fixed-step solver, enter the value that you entered as the Fixed step size configuration parameter or an integer multiple of that value.

Programmatic Use

Block Parameter: SampleTime

In Connected IO mode, enter the number of timer ticks that your model can lag behind the real-time kernel. When the model lags behind by this number or fewer timer ticks, the software assumes that the lag is temporary. It allows the model to catch up, even if the model misses some ticks. When the model lags by more than this number, the software reports an error and simulation stops.

In Run in Kernel mode, the software ignores this value.

Programmatic Use

Block Parameter: MaxMissedTicks

In Connected IO mode, select this check box to send the number of missed ticks to output port Missed Ticks.

In Run in Kernel mode, the Missed Ticks port is zero.

Programmatic Use

Block Parameter: ShowMissedTicks

In Connected IO mode, select this check box to grant other programs more CPU time while the kernel waits for a response from the hardware.

In Run in Kernel mode, the software ignores this value.

Programmatic Use

Block Parameter: YieldWhenWaiting

You can read 1–8 fields from each channel. Use this parameter to ignore implementation-specific information and receive only the fields that your application requires.

Programmatic Use

Block Parameter: ChannelFields

Define the data type of the output port.

To open the Data Type Assistant, click the >> button. To close the Data Type Assistant, click the << button.

Programmatic Use

Block Parameter: DataTypeStr

Use a built-in type, such as double or one defined by a data type expression.

Programmatic Use

Block Parameter: OptParam

Set of built-in types that are available for constructing data type expressions.
