The existing program functions perfectly when we re-download it, but ours gets stuck in an AOI loop between stopping/stopped states. So far we've tried:
Scan times
Deleting all instances of the P_VSD instruction, deleting the AOI and importing from the existing program
Power-cycling the drives
Has anyone seen this before? Everyone at the plant is at a loss..
Edit: We fixed it! It was a one button click fix (as it always is..). When doing your input/output/AOI mapping, make sure to put the input first, the AOI second, and the output last. That way when the task scans, the inputs update, the AOI executes, then the outputs trigger. It was stuck in a loop because the AOI was last in the program structure. So dumb, but since I'm new to PLCs I wasn't thinking about scan order..
