Hi,
I am gone through complete details and manuals , format my machine around 5 times . but i am still facing the same problem in 20 fa.
my machines is runig normal in manual mode , edit mode , momery mode , but gives an error of buffer overflow when i try to run it on DNC, and if i run the same progrramm after storing in memory then its run good.,
after analysing the dnc mode i found that my machine Schedular function is not working , in built flopy drive i.e FDCAS for exection of programm is empty , ,,
, another hand PMC side , my I/O Sequence program is fine , parametres are ok .. but i cant see any data if i viw list in FDCAS, in pmc side, my f rom is empty , thers no floppy and no NC data in machines ,
i have all these back ups of PMC,PARA,Ladder and list of parametres even . I read some where that K17,K18,K19 ONE OF THEM data of ladder is transferes or automatically transfer to in f rom, after editing.,
so please suggest what should be done and how to transfer ,
As suggested earlier , looking for a same machine I Got one locally around here but he is asking a big amount for the data and even i dont know wheres this problem is ?
what data should i copy and how , i am not having any memory card , to copy data./

looking for your kind reply

So are you just trying to write your programs to memory using the DNC software? I am not very familiar with setting it up for dripfeed as it appears you are trying to do. However buffer overflow is typical when your baudrate is set to high or not set the same in the CNC as in the PC. On the 20series I believe the buffer can accept 16 characters so it should not be an issue with the FIFO buffers but it could be. Go to your control panel in your PC and select the port you are using and click advanced. Turn down your FIFO transmit.

thanks Stevo but i have tried all these thing s i have tried even 300 baud rate , , see what happens is that basically when we run a machine on dnc if we stop our hand feed the program is not executed and we can put our machine to stand still at any end of block , now when we execute a programm from memory its working fine stops at end of block , but when we use dnc the data transfering remain countinuious even we switch offthe manual feed , then we have to start again. and if we stop again to see the job to flush chips . it again buffer over flow ,
if we slow down data machine has to wait for line to come , typicaly in laymans language , no stop bits are working , but checking with typical data flow softwares , i see that data overflow ,
what i found is that long back my card bursted , and my machine interal flopy drive data got lost now i am not having any nc language data in my machine , and secondly most important is the scheduling function ,
What i think is that RS 232 DATA IS TRANSFERED IN interal floopy drive then its executed from there , problem is at this place ,
I AM in trouble from around 1 year , even though my machine working , Makinoo people and fanuc people are confused ,
I guess you are too experianced in the same field , and i even tried a card replacement , the same problem remains, what do u suggest in this case ,

PM sent.

I think this is basic communication issues but you considered too much.

On communication software has two protocols
1. software protocol Xon/Xoff
2. hardware protocol through 25pin( 4,5,6,8 20 rs232 socket)

You need select on your software to choice one handshake mode.
