Fanuc OM-A or OM-B system PMC problem.

[rai]

I have a Fanuc OM-A & B models it's ladder got lost, I don't have it's EPROM's. I would like to load the new ladder in these systems. Earlier I had loaded the ladder in Fanuc OM-C & D models using RS232 port & I am not familiar with Fanuc OM-A & B models. Can somebody help me & tell me the parameter number for PMC loading menu display as earlier I had used in Model OM-C & D. ( Parameter #71 bit #6 ) Can I use Parameter # 71 bit #6 same way as I had used in model OM-C & D? I would appreciate for sending me manuals for Fanuc OM-A & B model specially connection manual hardware & maintenance.
