FANUC Alarm VISN-005 — WARN Line not found in the image
FANUC VISN-005 (“WARN Line not found in the image”): FOUND_LINE or FOUND_PLANE cannot determine the geometric parameters because the location tool in the vision process failed to find the line in the image. First check: Use the vision training menus to determine why the line was not found, and retrain the location tool if necessary.

Description
FOUND_LINE or FOUND_PLANE cannot determine the geometric parameters because the location tool in the vision process failed to find the line in the image.
Remedy
Use the vision training menus to determine why the line was not found, and retrain the location tool if necessary. Add logic to the vision KAREL program to call the FOUND_OK built-in to check if the vision process found the line before calling FOUND_CIRCLE. Do not call FOUND_LINE or FOUND_PLANE if FOUND_OK returns FALSE.
