Dear Old Sinumerik experts,

I am working on old machine (2007 milling) equipped with Sinumerik 840D powerline /Shopmill v6

I would like to understand Shopmill commands/blocks such as E_HEAD and E_CONFIG to use them in G-Code NC-programs instead of WORKPIECE Command that is recently used in 828D and modern Shopmill.

can you assist me on that?
at least these commands. but it will be better to have a reference for these cycles similar to " Programming Guide 11/2002 Edition: Fundamentals "
