PMC-L OE1 and OE2 combining to #ex
Folks,
I need to add drip feed to an older 0-MC with PMC-L. I have an EPROM reader and grabbed the images from OE1 and OE2 to pull into the old DOS fladder software, but I'm curious about how the binary data from the EPROMs needs to be combined (and then split again after the ladder is edited). I'm assuming that the address layout is such that one chip contains the high order byte, the other the low order byte, but wanted to see if anyone can tell me for sure. I wouldn't put it past Fanuc to have swapped address lines just to obfuscate things.
Yes, I know I can pay the extortion fee for the converter software from 3BH, but I'm not really interested in going that route. I can easily write a script to combine the files once I know the address mapping. I'm hoping that someone can share that info so I don't have to go the route of borrowing a logic analyzer to hook up to the address/CS/OE lines on the EPROMS and decode the addressing layout by watching the PMC load from the chips.
Thanks!

can you share me the software how to converter the file.bin to file.#ex????
Thanks.

I can send a copy of the .BAS program and would like to see a similar program for other Fanuc ladders.
Dear friend.
Can you share me the program converter rom Fanuc 6m to ladder??

Re: PMC-L OE1 and OE2 combining to #ex
SO, FOR A FANUC 0 PMC-L
YOU NEED A FANUC ROM WRITER AND A FAPT LADDER WITH AN OLD VERSION 5 OR OLDER WITCH IS RUNNING FROM DOS ....
PMC-L OE1 and OE2 combining to #ex
Correct. You can use a generic EPROM reader/writer to read or write the individual chip images for things like backups, but the FA writer or PC writer and the DOS FAPT Ladder software is necessary if you need to create a single #EX that is needed to further decompile the ladder. The same is true for compiling, you can compile the code into a #EX, but splitting it onto OE1 and OE2 images requires the Fanuc reader/writer unit.
