Sample State Information

Byte	Name	Type	Description
0-1	Inputs	16u	Digital input state of the last frame.
2-9	Z Index Position	64s	Encoder position at time of last index pulse of the last frame.
10-13	Exposure	32u	Laser exposure in µs of the last frame.
14-17	Temperature	32u	Sensor temperature in degrees Celsius * 100 (centidegrees) of the last frame.
18-25	Encoder Position	64s	Encoder position of the last frame when the image data was scanned/taken.
26-33	Time	64u	Time stamp in microseconds of the last frame.
34-41	Frame Counter	64u	The frame number of the last frame.
42	Buffer Count	8u	Represents the number of frames waiting to be output if buffering is enabled.
43	Buffer Overflowing	8u	Indicates whether the output buffer has overflowed: 0 - No overflow 1 - Overflow
44 - 79	Reserved		Reserved bytes.
80-83	Measurement 0	32s	Measurement value in µm (0x80000000 if invalid).
84	Decision 0	8u	Measurement decision. A bit mask, where:   Bit 0: 1 - Pass 0 - Fail   Bits 1-7: 0 - Measurement value OK 1 - Invalid value 2 - Invalid anchor

375-378	Measurement 59	32s	Measurement value in µm (0x80000000 if invalid).
379	Decision 59	8u	Measurement decision. A bit mask, where:   Bit 0: 1 - Pass 0 - Fail   Bits 1-7: 0 - Measurement value OK 1 = Invalid value 2 = Invalid anchor

Measurement results are reported in pairs of values and decisions. Measurement values are 32 bits wide and decisions are 8 bits wide.

The measurement ID defines the byte position of each pair within the state information. The position of the first word can be calculated as (80 + 5 * ID). For example, a measurement with ID set to 4 can be read from byte 100 (high word) to 103 (low word) and the decision at 104.

In Profile mode, the measurement results are updated after each profile is processed. In Surface mode, the measurement results are updated after each discrete part has been processed. If buffering is enabled in the Ethernet Output panel, reading the Extended Sample State Assembly Object automatically advances the buffer. See Ethernet Output for information on the Output panel.
