2.Operand D occupies 8 consecutive word registers. The function of each device is as below:

No.	Content	Range	Format
D + 0~1	Zenith	0 ~ 90	Float
D + 2~3	Azimuth	0 ~ 360	Float
D + 4~5	Incidence	0 ~ 90	Float
D + 6	Converted DA value of Zenith	0 ~ 2000	Word
D + 7	Converted DA value of Azimuth	0 ~ 2000	Word

Note

Horizontal=0 North point=0

1LSB = 0.045

degree

1LSB = 0.18

degree

3.The execution time of SPA instruction costs up to 50ms, therefore we suggest users to execute this instruction with an interval not less than 1 sec, preventing the instruction from taking too much PLC operation time.

4.Definition of Zenith: 0° and 45°.

0°

5.Definition of Azimuth:

N

0°

270°

180°

45°

90°

6.The correct time of the local longitude: If we suppose that it is AM8:00:00 in Taipei, and the longitude is 121.55 degrees east, then the correct time of the local longitude in Taipei should be AM8:06:12. Please refer to API168 DTM instruction (parameter k11) for more explanation.
