Visual Inspection System Protocol
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, CIO 28909 (if port
A is used) or CIO 28913 (if port B is used) will turn ON.
4. Data to be output is within the range 999.999 (upper limit) to –999.999 (lower limit).
5. Retry processing is not performed for this sequence.
6. Turn the Abort Bit ON and then OFF to end this sequence.
Camera Designation and Positioning (F350) (Sequence No. 471)
This sequence designates the cameras for measurement.
Send Data Word Allocation (2nd Operand of PMCR)
First word of
send data
Receive Data Word Allocation (3rd Operand of PMCR)
None.
Note 1. Set values so that the first camera No.< last camera No.
2. If a designated camera No. is abnormal, CIO 28909 (if port A is used) or CIO 28913 (if port B is used)
will turn ON.
