Hard to say. I don't know what is inside your motion_control.txt file, so I can't tell where the problem is.

This file needs a PROGRAM. It won’t compile if it doesn’t have a PROGRAM defined. Why don’t you just use the blocks in your program as posted in the link you sent?

Just create a project with your block and then export it to .st by clicking on the orange down arrow at the toolbar. You will see that the exported program contains a PROGRAM definition. To compile it with MatIEC you will have to remove the bottom comments wrapped in (* *)
