Manufacturer wording — WARN Invalid algorithm type %d
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC VISN-033 (“WARN Invalid algorithm type …”): You called a built-in routine with VIS_PROCESS that uses an algorithm which is not appropriate for that built-in. First check: Check the built-in description for restrictions on the parameters.

Description
You called a built-in routine with VIS_PROCESS that uses an algorithm which is not appropriate for that built-in. For example, you cannot call FOUND_MODEL with a VIS_PROCESS which has been trained as a connectivity tool.
Remedy
Check the built-in description for restrictions on the parameters. Make sure that the VIS_PROCESS parameter contains data appropriate for the built-in routine being called. The value of "xxx" indicates the type of VIS_PROCESS you passed in: 16. Shape Matching Feature Find Location Tool 17. Scanning Feature Find Location Tool 18. Edge Tracing Feature Find Location Tool 19. Contour Match Location Tool 20. Combine FF List Vision Process 21. Match List Vision Process 22. Automatic Object Find Location Tool 23. Connectivity Location Tool 24. Master Vision Process 25. Found Feature Measurement Tool 26. Gauge Measurement Tool 27. Pixel Statistics Measurement Tool 29. Feature Find Location Tool, algorithm not specified
