 Detailed Explanation of Functions

 

Vision Sensor Dedicated Commands and Status Variables

  9-98 

 
[Errors] 

(1) 

If data type for an argument is incorrect, a 

"syntax error in input command statement"

 error is 

generated. 

(2) 

If there is an abnormal number of command arguments (too many or too few), an 

"incorrect argument 

count"

 error occurs. 

(3) 

If the <vision sensor number> is anything other than "1" through "8", an 

"argument out of range"

 error 

occurs. 

(4) 

If the NVOPEN command is not opened with the number specified as the <vision sensor number>, an 

"abnormal vision sensor number specification"

 error occurs. 

(5) 

If the vision program's image capture specification is set to anything other than "Camera" (all trigger 
command), "External trigger", or "Manual trigger", an 

"abnormal image capture specification" 

error 

occurs. 

(6) 

If the vision sensor is "offline", the 

"Put online"

 error occurs, so put the vision sensor "Online". 

(7) 

If the communications line is cut while this command is being executed, an 

"abnormal 

communications"

 error occurs and the robot controller side line is closed.
