semens 808D

Hey all.
Can anyone help with programming a subroutine/subprogram please ?

The program is Fanuc on Seimens 808D basic.
I have 2 datum points set up on the milling table G55 and G56
I will call the subprogram .....LABEL1
I know I must finish the subprogram with M17

I will position the cutter at the respective Datum points and call the subprogram. My problem is what is the command to call the subprogram ?
Also do I write the subprogram at the start of the main program ?
Thanks for any advice offered.
Dave.

Ok don't know siemens, so it may not apply. In Fanuc, there are 2 types of subprograms, local and global(?) Not sure of exact terminology as I don;t use them much... One uses M98 to call the subprogram and one uses M99. Don't remember which is which... one is local contained in the main program body, and one is global(?) contained in the controller as it's own program if that makes sense...

edit: sorry, think it might be M97 and M98 as M99 is the loop command...

Hello Mike,
Still no Cigar.

With a Fanuc Control that is able to Call a Subprogram by Sequence Number (introduced with the FS16i control) M98 is used to Call both Local and External Subprograms; with a Q address for a Local Subprogram, with a P address for an External Sub, with a P and Q address to start at a particular Sequence Number (specified by the Q address) in the External Sub. Whether Local, or External Subprogram, M99 is used to return control to the Calling Program. Haas uses M97 to call a Local Subprogram and M98 for an External Subprogram.

Regards,

Bill
