Alot Of Code A Little Memory?

[SWPM]

Does anyone no what parameters need changed on a fanuc "16" or "18" to be able to drip feed from a memory card ? we have been using memory cards to load into the machines memory but have not been able to read direct from the card. Any help would be appreciated

Hi!

Did you change your channel to 4 ?

0= RS-232
1= RS-232
2= RS-232
3= floppy drive
4= SRAM memory
5= Hard disk and FTP

PRM 138 bit #7, I/O channel=4

There's a group of parameters you need to set to accomplish this.

Set the machine into "MDI" Mode.
Press the OFFSET/SETTING button.
Change/Set the “I/O Channel” to “4”
Set "Parameter Write Enable" to "1"
Press the Cancel AND Reset buttons simultaneously. This will clear the alarm you get stating parameter write is enabled.
Press the "SYSTEM" button.
Press the numbers "138" on the key pad then "NO. SRCH" on the soft keys (below the CRT). You'll need to set bit 7 to a 1 (Bit order is as follows - 7 6 5 4 3 2 1 0 - so you'll want to change the furthermost bit to the left to a 1)
Press "3403" on the key pad then "NO. SRCH" on the soft keys. Arrow over to bit 2 (3rd bit from the right) and change that to a "1"
Press "6300" on the key pad then "NO. SRCH" on the soft keys. Arrow over to bit 4 (5th bit from the right) and change it to a "1".
Press the OFFSET/SETTING button to get back to setting and set Parameter Write Enable to a "0". Press Reset.

Now, this will allow you to run directly off your memory card.
Your main program in your machine control will just need to look like the following;
%
O100(MAIN PROGRAM)
M198P1234
M30
%

Your program on the memory card MUST be named Oxxxx (the exes being a 4 digit number that MUST correspond to the actual Sub Program Number in the sub program. (ex. O1234) with NO file extension.
Your program on the memory card must be as follows (making sure the M198 P call AND the O number AND the Sub Program Number match as I've shown)
%
O1234(YOUR PROGRAM NAME HERE)
(YOUR PROGRAM AS NORMAL)
M99
%

You MUST have a memory card in the slot when “M198” is called or you will get a BP/S alarm.


I've accomplished this on a 31iM-a Control, a 0iM-a, some 16i's (but not all) and some 18i's.

Use this as a guideline and if it does not work, contact your machine tool builder/dealer. They are usually your best (and often untapped) resource.

I think that you need to have the floppy directory option installed to get M198 to work.. THe manual says so.

[James Meyette]

That could very well be the case. I'd need to compare a machine that I was not able to get it working on vs. a machine that I was able to get it working on...

When it works though... it definitely beats the daylights out of RS-232 drip-feed without a doubt.

i think it isd 3404 that are to be changed and not 3403... call for prog nr instead of file nr on card.

[James Meyette]

Yes, you are correct, darn fat fingers... Thank you for the correction.

[SWPM]

I got the program to drip feed from a card and now it will not read the code fast enough, I have finally broke down and have some guys coming out to install the max amout of memory avaiable for the machine. I appreciate all your help as this isnt my strong point in the field

Thanks everybody

there are parameters to set to get it to highspeed operation and to look ahead..
