Data cannot pass to Subroutine - Studio5000 ST

[PLC1234]

See image below. Look at line 95. I tested all data type, but none of them works.

See this. TEMPDATA2 is used only there. No other part of the program modify it.

Why? How to solve? Please help.

What about being modified from hmi or from another plc as produced/consumed.

Is the routine being called?

All this is telling you that, while CAMERA_TOP_SEQ_INDEX = 11, the exact instant that CV_X_TOP:I.Data[0].0 was set, CV_X_TOP:I.Data[12] was equal to 0.

It may have changed to 664810 a few msecs later, but by that time, you had set the INDEX to 12, and thus would not execute the logic any further.

If you truly expect Data[0].0 to be 1 at "the exact same time" that Data[12] has a non-zero value ("the camera is telling me it took the picture; so I should be able to read the result), you may want to put a small time delay on Data[0].0 being true, and use that before executing the IF-THEN. Just to give the camera a moment to finish sending the data that obviously is there.

Then again, it may be that the camera doesn't send Data[12] until after you've turned off CV_X_TOP:O.Data[0].0, which would also explain your screen capture.
