Dripfeed Fanuc 20-T

Hello,

I have some questions about a Fanuc 20-T.This control is mounted on a Schaublin CCN125 from aprox.1995.

We purchased a PCMCIA 6mb Sram card to run NC programs from this card.
In MDI mode this card is visible and I am able to read en write parameters to the card.
The card is not visible in EDIT Mode.I read on the internet the Fanuc control has to be in I/O 4.
On our control only I/O channels 0,1 and 2 are available and not I/O 4. channel.
How do I manage to cnc from this card?In other words:I put a O cnc program on it and how to read and run the program.We need to run CNC programs from this card because we use CAD/CAM to control the machine.Our internal memory in the 20-T is only 16K

Another thing is how we can DNC dripfeed or Blockwise on this machine via RS232?We can write and read programs to and from the machine.Is it possible to dripfeed with this Fanuc 20-T and how we set the machine ready to receive long cnc programs.


I hope someone can help me.
