WriteRegister_UDINT
This FB writes a DINT value into a register on the camera. Requires an open control channel (e.g. by calling FB_VN_GevCameraControl.OpenCamera() before)
Syntax
Constructor:
WriteRegister_UDINT(
OTCID oidITcVnGevImageProvider
)
Execute main:
FB_Main()
FB_Main(
GVCP_REGISTER_ADDRESS nAddress,
ULONG nValue,
bool bWrite
)
FB_Main(
bool bWrite
)
Inputs
|
Name |
Type |
Default |
Description |
|---|---|---|---|
|
nAddress |
|
The address of the register that should be written | |
|
nValue |
ULONG |
|
The value to write |
|
nEndian |
USHORT |
|
OPTIONAL: The endianness of the register. 0 = Big, 1 = Little. Default: 0 |
|
bWrite |
bool |
|
Writing 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. |
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. |
