ReadRegister_REAL

This FB reads a REAL register from the camera. Requires an open control channel (e.g. by calling FB_VN_GevCameraControl.OpenCamera() before)

Syntax

Constructor:

ReadRegister_REAL(
    OTCID oidITcVnGevImageProvider
)

Execute main:

FB_Main()

FB_Main(
    GVCP_REGISTER_ADDRESS nAddress,
    bool                  bRead
)

FB_Main(
    bool bRead
)

Name	Type	Default	Description
nAddress	GVCP_REGISTER_ADDRESS		The address of the register that should be read
nEndian	USHORT		OPTIONAL: The endianness of the register. 0 = Big, 1 = Little. Default: 0
bRead	bool		Reading the register is triggered by a rising edge at this input.
nTimeout	unsigned int	VISION_ADS_TIMEOUT	Indicates the time before the function is cancelled.

Name	Type	Description
fValue	float	The read value
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.
