CAMAT RES MEASUREMENT BLOCK (0xFA)

Code: 0xFA
Description: Spontaneous message from the SRV image processing sensor for transmitting the results of the image processing.
Response (slave -> master): The answer contains a fixed part and a variable part, which is dependent on the function type in the activated program of the SRV.

In the fixed part, the following 4 parameters are transmitted as 2 byte integer number (16 bit Intel format: Low-Byte, High-Byte):

• Program ID is the ,,SPS-ID'' of the activated program.
• Function ID is the ID of the active function (-1 = 0xff, 0xff with program result).
• Function type: The type of the function from the SRV functionality.
• Result: Good (0), bad (1)

This is followed by the variable part, depending on the function type. Depending on the units system set, the transmitted values are transmitted either as 4 byte integer number (32 bit Intel format (lowestvalue Byte first)) or as 4 bytesFloat (floating point numbers with simple precision, 32 Bit IEEE 754 format):

• Pattern search / Tracking
  • Match: Milli-percentage (Integer) or percentage (Float)
  • Position X: Micrometer (Integer) or millimeter (Float)
  • Position Y: Micrometer (Integer) or millimeter (Float)
  • Rotation: Micro-degrees (Integer) or Milli-degrees (Float)
• Area test
  • Area: Micrometer^²*1000 (Integer) oder mm^² (Float)
• Gray value
  • Gray: 0..255 (Integer or Float)
• Brightness percentage
  • Brightness: Percentage (Integer or Float)

Note: Only for SRV image processing sensor.
