BOOL |
0 或 1 |
显示采集图像中的字符。 通过 mapp Vision HMI 应用程序进行操作。 |
W |
|
该值不应大于实际可查找的代码/字符集数量,否则可能会不必要地延长图像处理例程的运行时间。
信息:
该值不必与配置变量 NumResultsMax 相同,因为它只是 POWERLINK 框架的占位符。
信息:
理论上也可以设置 "NumSearchMax = 0"(不单独检查),这样在执行视觉功能时会触发搜索 0 个结果。
感兴趣区域(ROI)的方向偏移。方向以 1/100 度的增量指定。
对于 -179.99° 至 +180.00° 的角度范围,可使用的数值范围为 -17999 至 18000。超出此值范围的值将被解释为 +180°。
该参数用于执行字符搜索,并在 mapp Vision HMI 应用程序中显示找到的区域(找到字符的轮廓)。
信息:
该参数在 I/O 映射中不可见。操作通过 mapp Vision HMI 应用程序进行。
The parameters specified in this section are part of the I/O mapping of the hardware module that can be accessed via Automation Studio.
BOOL |
0 or 1 |
Enables/Disables the function |

|
|
USINT |
0 to 255 |
Maximum number of character strings (words) to be searched for |
W |
|
|
UINT |
0 to 100 |
Minimum grade (threshold value) of the character with the smallest confidence value in the word to be searched for or in the ROI. In percentage steps. |
W |
|
|
DINT |
-2622400 to 2622400 |
Offset of the ROI in the x-direction in 1/100 pixel increments. |
W |
|
|
DINT |
-2622400 to 2622400 |
Offset of the ROI in the x-direction in 1/100 pixel increments. |
W |
|
|
INT |

W |
|
|
DINT |
-2622400 to 2622400 |
Offset of the center of rotation in the x-direction in 1/100 pixel increments. |
W |
|
|
DINT |
-2622400 to 2622400 |
Offset of the rotation center in the y-direction in increments of 1/100 pixel. |
W |
|
|
BOOL |
0 or 1 |
Displays characters found in the acquired image. Operation takes place via the mapp Vision HMI application. |
W |
|
Enables/Disables the vision function.
Values |
Information |
|
---|---|---|
BOOL |
0 |
Image processing disabled (default value). |
1 |
Image processing function enabled. |
Parameter for the maximum number of codes / character sets to be found.
The value should not be greater than the actual locatable number of codes / character sets; otherwise, the runtime of the image processing routine could be unnecessarily extended.
Information:
This value does not have to be identical to configuration variable NumResultsMax since it only serves as a placeholder for the POWERLINK frame.
Information:
Theoretically, "NumSearchMax = 0" can also be set (it is not checked separately), which triggers a search for 0 results when the vision function is executed.
This parameter makes a grade with respect to an accepted detection quality.
Values |

UINT |
0 to 100 |
Minimum grade (threshold value) of the character with the smallest confidence value in the word to be searched for or in the ROI. In percentage steps |
Offset of the region of interest (ROI) within the image area in the x-direction.
Values |
Information |
|
---|---|---|
DINT |
-2622400 to 2622400 |
Offset of the ROI in the x-direction in 1/100 pixel increments. A position from -26224.00 to 26224.00 pixels can therefore be selected. |
Offset of the region of interest (ROI) within the image area in the y-direction.
Values |
Information |
|
---|---|---|
DINT |
-2622400 to 2622400 |
Offset of the ROI in the y-direction in increments of 1/100 pixel. A position from -26224.00 to 26224.00 pixels can therefore be selected. |
Offset to the orientation of the region of interest (ROI). The orientation is specified in increments of 1/100 degrees.
For the angle range of -179.99° to +180.00°, this results in a usable range of values of -17999 to 18000. Values outside this range of values are interpreted as +180°.

DINT |
-2622400 to 2622400 |
Offset of the center of rotation in the x-direction in 1/100 pixel increments. A position from -26224.00 to 26224.00 pixels can therefore be selected. |

DINT |
-2622400 to 2622400 |
Offset of the rotation center in the y-direction in increments of 1/100 pixel. A position from -26224.00 to 26224.00 pixels can therefore be selected. |
The parameter performs a character search and displays the found regions (contour of the found character) in the mapp Vision HMI application.
Information:
This parameter is not visible in the I/O mapping. Operation takes place via the mapp Vision HMI application.
