There are many Mitsubishi systems on the market, but I feel that the information is relatively scarce, not as rich as the FANUC system.
Today, let's summarize the parameters and signals related to Mitsubishi Lock:
1166=1, in edit mode, fixed cycle macro programs can be opened and edited.
8105: Edit lock B (edit lock for program numbers 8000 to 9999)
1121: Edit lock C (edit lock for program numbers 9000 to 9999)
1122: Program display lock C (disable display/search for program contents with program numbers 9000 to 9999 in the memory)
