How to automate creating this profile?

AS you see this figure is cube along the curve with slots (1). Using follow me tool I only able to create figure without gaps. After that i have to add slots manually. How to automate creating this?

You could create it as a straight run of blocks with the gaps and make the whole run a component. Then use Shape Bender to bend it to the curve.
