Problem- 21i-MA - Memory Card

[aaronson]

I can read programs from the memory card to the control memory. I can copy parameters and programs from the control memory to the card. I would like to be able to DNC large programs from the memory card, but I can't.

I followed the instructions in previous posts on this topic. I don't get the DNC-CD and DNC-ST soft keys. I get an alarm 3 - "too many digits", when trying M198 to run a sub-program from the memory card.

I have I/O = 4

Does anybody know if the 21i-MA is able to support DNC from the card?
Do I need to purchase any options from Fanuc to support this?

Thanks,

Parameter #138 bit 7 = 1 enables DNC from memory card.

[aaronson]

Thanks for responding dcoupar, I tried 138.7 with no luck.

I doubt that dnc from memorycard for the21ia is available, even as an option. The earlier 18ia control software did not have it either- needed a software upgrade. Call Fanuc (good luck!) to find out what the status is and please post it here.

[dcoupar]

memoryman is probably right. Interestingly enough, the 21i/210i/210is - MA Operator's Manual (GFZ-63094EN/02) section 4.10 details DNC Operation with Memory Card. This is a GE Fanuc manual, not a regular Fanuc manual.

Does the screen display RMT when you put it in TAPE or RMT mode?

[aaronson]

Yes, when the selector switch is set to DNC, the screen shows RMT.

dcoupar,

I only have the 63094EN/01 manual. Do you have the GFZ-63094EN/02 in PDF format?

The "Too many digits" alarm resulted from having a setting of 2 for the M address parameter.

One I got over that, the M198 didn't cause an alarm, but just hung up with the cycle start light on.

To test the M198, I set the I/O to 0 and the device type to 3 (serial connected floppy cassette ?) and connected to a terminal window on a PC. The M198 sent A: to the PC. I guess that is part of a strange fanuc protocol.

Check out parameter 3030 - number of digits for M code, sounds like this parameter is not set to 3 hence your alarm.
