Is it possible to make a custom program M Code without end of program which is M30 or M02 ?

The requirement is such that the operator needs to login into the machine when he arrives for his shift and if a part program (a long cycle time one) is already running on the machine then he has to run the login M code from MDI mode after executing feed hold in single block (after completion of the block under execution). Any M30 or M02 at the end of custom M Code program will end up resetting the auto cycle which defeats the whole purpose.

Thanks

Since the program execution is line-by-line, you may choose not to have M30/M02 at the end of a program.

How about M00? Or you can use block skip (Block delete)

/M30 will skip if block skip is on.
M00

This does not work as any program has to have either M30, M02 or M99 at the end Or any custom M Code which is defined in ladder as end of record M Code.

I havent tried this but even otherwise this will dependant on operator being conscious of having to switch on block skip on machine which is not desirable.

Any custom M Code program can end with M99. Since the M Code will either be called from a main program Or from MDI mode, the M99 will make it return to the main program Or MDI screen. MDI screen inputs need not have M30 and hence the problem of resetting is solved.

Got this reply from Fanuc which was an obvious solution but it never occurred to me. One look at the standard M6 macro (used of most Fanuc machines) would have given this idea.

Hello yaji63,

I'm curious about this ... how exactly does the operator login at the machine?
