The vision program status storage device value is refreshed at the following timing.
(1) When a job is loaded by the MVLOAD instruction or MVPST instruction.
(Refreshed immediately after loading.)
(2) When the vision system's online/offline status changes.
(3) When a job is loaded from a source other than the Motion CPU (In-Sight
Explorer, etc.). (Refreshed several seconds after loading.)
(4) When job is loaded and an online vision system is logged onto with the
MVOPEN instruction. (Refreshed several seconds after logging on.)
(e) Read Value Cell/Read Value Storage Device
Set this to store the vision system tag or numeric data of spreadsheet in the
Motion CPU device.
This does not need to be set if the numeric data does not need to be
referred to.
POINT
(1) The vision system image data can be stored in the image data storage device
by setting the format output string setting of TCP/IP protocol.
(2) When the data stored in the set tag or spreadsheet cell is not an integer value,
the value after truncation of decimal point is stored in the read value storage
device.
(3) If a spreadsheet cell is designated when using the vision system In-Sight
