Fanuc programs can be separated into the following program number groups

Fanuc programs can be separated into the following program number groups:


Program Number Range


Description


O0001 to O7999


Standard program numbers (typically for the main programs)


O8000 to O8999


Macro program number Group 1


Can be locked by a setting


Macro program numbers for special applications


O9000 to O9049


Can be locked by a parameter


(used with G, M, S, and T functions)


O9000 to O9999


Macro program number Group 2


Can be locked by a parameter

Macro Pro gram Pro tec tion


The ma jor ity of stan dard CNC pro grams do not need pro tec tion of any kind When the word


pro tec tion is ap plied to these pro grams, it means one or both of the fol low ing at trib utes can be as –


so ci ated with the pro gram num ber:


o


Visibility of the pro gram on the control screen (pro gram di rec tory display)


o


Ed it ing of the pro gram contents (also in clud ing pro gram de le tion)


Macro pro grams need pro tec tion more than subprograms, and subprograms need more pro tec –


tion than the stan dard pro grams When plan ning a macro pro gram, it is im por tant to un der stand
