Downloading Big pmc File into PPMAc.

Recommended Posts


I"m Using Power PMac(UMac)


I Have a program NC-code witch has three sub-programs.

sub prog size is 1. 2 MB, 2. 80 MB, 3. 100 MB, each.


The Problem is...


 It takes a lot of time for downloading sub prog.

and my PMac's  memory amount is only 320 MB.

so i can not use sub=prog that size exceed over 300 MB(aprox)


is there anyway to run program directly from usb memory or hdd of PC? Like Fanuc Controller SYstem?


Using Rotary Buffer is the only way to solve this program?


If anyone has same issue of me, or know the answer about this.


Please Answer me.

Hi, you can upload the NC file to the PMAC with a FTP client (e.g. FileZilla). The destination folder should be in /var/ftp/usrflash/.

Then, issue the following command to ininitialize the sub prog:

// No space between -i and /var
gpascii -i/var/ftp/usrflash/Temp/mysubprog.nc


And don't forget to enclose the subprog code in the following structure:

open subprog xxx
<subprog code>

In the c language project, add the reading program, use the PMAC_linux command to load the NC program, and realize the NC program you need to dynamically load the usb.

is there any smaple code i can get?

if any, let me know please.
