ReadNeuralNetwork

This FB reads a neural network from a file on the target pc.

Syntax

Constructor:

ReadNeuralNetwork()

Execute main:

FB_Main()

FB_Main(
    PCCH                 sFilePath,
    ITcVnNeuralNetwork** pipDestNeuralNetwork,
    bool                 bRead
)

FB_Main(
    PCCH                 sFilePath,
    ITcVnNeuralNetwork** pipDestNeuralNetwork,
    TcVnArray33_UDINT*   paInputShape,
    bool                 bRead
)

FB_Main(
    bool bRead
)

 Inputs

Name

Type

Default

Description

sFilePath

PCCH

Full path of the file or relative path to the default directory on the target pc

pipDestNeuralNetwork

ITcVnNeuralNetwork**

Returns the neural network

paInputShape

TcVnArray33_UDINT*

Optional input shape for testing the execution of the neural network model. The error code INCOMPATIBLE is returned if the execution fails. Setting aInputShape = 0 or aInputShape[0] = 0 disables the testing of the execution.

bRead

bool

Reading the file is triggered by a rising edge at this input.

nTimeout

unsigned int

VISION_ADS_TIMEOUT

Indicates the time before the function is cancelled.

 Outputs

Name

Type

Description

bBusy

bool

This output remains TRUE until the function block has executed a command, but at the longest for the duration supplied to the 'nTimeout' input. While bBusy = TRUE, no new command will be accepted at the inputs.

bError

bool

This output is switched to TRUE as soon as an error occurs during the execution of a command. The command-specific error code is contained in ‘nErrorId’. If the function block has a timeout error, 'bError' is TRUE and 'nErrorId' is 1861 (hexadecimal 0x745). Is reset to FALSE by the execution of a command at the inputs.

nErrorId

ULONG

Contains the ADS error code or the command-specific error code of the last executed command. Is reset to 0 by the execution of a command at the inputs.
