■Description, data type of result
Setting data Description
(S1) Vision system (camera) No. issues a trigger (1 to 32)
(S2) Timeout time until execution result is received from vision system (1 to 32767) [10ms]
Processing details
• The job is executed if a trigger is issued to the vision system specified with (S1) and the result is stored in the image data
storage device set in the vision program operation setting parameter.
• The Motion SFC program execution transits to the next block without waiting for the process completion. After the job is
ended in the vision system and the sending of image data (created by vision processing) by TCP/IP protocol is completed,
the status storage device value set in the Ethernet communication line setting parameter is 40 (Image data reception
completed). When the read value is set in the vision system parameters, the data is stored in the read value storage device,
and the status storage device value set in the Ethernet communication line setting parameter is 50 (value cell reception
completed).
• (S2) is set in increments of 10ms. When the setting is omitted, the timeout time is 10 seconds (same as setting 1000).
Operation error
An operation error will occur if:
• The (S1) data is outside the range of 1 to 32.
• The (S2) data is outside the range of 1 to 32767.
• The vision system specified with (S1) has not been logged on.
• The vision system parameter setting is different from the setting on the vision system.
• The tag specified with reading value cell or the spreadsheet data is not an integer value.
• The current process is not completed when the specified timeout time has elapsed.
