WriteRegisters_UDINT

This FB writes multiple UDINT registers on the camera. Requires the same endianness for the specified registers and an open control channel (e.g. by calling FB_VN_GevCameraControl.OpenCamera() before).

Syntax

Constructor:

WriteRegisters_UDINT(
    OTCID oidITcVnGevImageProvider
)

Execute main:

FB_Main()

FB_Main(
    GVCP_ADDRESS_VALUE_PAIR* pAddressValuePairs,
    USHORT                   nArraySize,
    bool                     bWrite
)

FB_Main(
    bool bWrite
)

 Inputs

Name

Type

Default

Description

pAddressValuePairs

GVCP_ADDRESS_VALUE_PAIR*

An array containing address/value pairs of the registers that should be written

nArraySize

USHORT

Number of address/value pairs in pAddressValuePairs

nEndian

USHORT

OPTIONAL: The endianness of the registers. 0 = Big, 1 = Little. Default: 0

bWrite

bool

Writing the registers 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.
