Fanuc O-T rs232 output issue

[garoweir]

Has anyone ever seen this before. I send a program to a machine with a Fanuc O-T controller in the standard format:

%
O1234
M30
%

When I upload the program back to the PC, I'm getting:

&HE:%
:1234
M30%

my concern is the first line. The various characters are messing up my DNC software's ability to compare the uploaded program to the original on file. Any ideas as to how to remove the "&HE:" ???

The relevant RS232 parameters that I'm aware of are:
I/0 = 0
2.0 = 0
2.2 = 0
38.6 = 0
38.7 = 1
70.7 = 1
552 = 11

Any help is greatly appreciated!

What is parameter 2.7? Should be set to 1.

What software are you using for Upload/Download? There may be settings to strip characters before the % sign.

Parameter 2.7 is indeed a 1. I wrote my own DNC software...so ignoring characters before the "%" is an option...but I was hoping to get away with a parameter change or something similar...

Thanks for the reply!!!

I had problems uploading from my ot control two but for some reason when I changed the parameter from ascii to iso at the machine it worked? It sdhouldnt have but did.

I ended up modifying my DNC software to omit everything before the first "%". I still bothers me a bit...so if anyone has any other ideas...I'd love to hear em...

Thanks for the suggestion dcoupar!!!

garoweir,

IIRC, we had to strip them out when receiving with SmartCAM's communicate, too. I believe they're control codes... nothing to be bothered about, as long as it's working.
