Illumination Fluctuation Follow Execution (F300)
(Sequence No. 465 (Hex 01D1))
This sequence executes an illumination fluctuation follow.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
Measurement Execution and Positioning (F350)
(Sequence No. 470 (Hex 01D6))
This sequence carries out one measurement and stores the measurement results in the specified words.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
Note 1. The number of models that can be stored in a designated word is 1.
2. If a measurement is carried out without executing a camera designation, a measurement is executed
for all cameras in which the measurement model is registered.
3. When the correlation value is less than 70 and the measurement value overflows, the following flags
will be turned ON. The flags for port 1 are CIO 190914 for the Serial Communications Board and CIO
