Fanuc OT

[CEF]

Hi all,


I am having trouble getting a program from my laptop to a Fanuc ot. I keep getting an error 085. Any suggestions?

Usually 085 is parity,framing or buffer overrun, communication error, check your baud rate and other protocol settings.
Are you using a 3 wire cable with the Handshake jumpered out.

Yeah, I am using 2400 baud rate,Rts/cts hardware handshake, I don't know if I am using a 3 wire cable, but I do know that I am using the cable that Fanuc told me to use. thanks for forwarding the PDF. I already had a copy of that but it is good to know that I wasn't chasing my tail thinking that the copy I had was correct.

The dnc software is sending the information but I just keep getting the 85 error. I do not know what else I can check?

You must use XON/XOFF, software handshake otherwise you get buffer overrun. This is why you can usually jumper the hardware handshake out.

I did try xon/off software handshake, 2400 baud rate even, 7 bits,% at the begging and end, correct cable connection, and I have tried numerous methods and combinations of these. I have had no luck. Could it be something in the program? Maybe too long? Wait I tried to making it shorter too.

I really have no idea where to turn to next? Any other suggestion or someone who might know?

Have you tried sending from controller to PC?
This confirms that most of the protocol is OK, right port etc.

How do I do that?

[Al_The_Man]

Do you not have the Operator manual for the machine?
In EDIT mode PRGRM [LIB] 0xxxx OUPUT START.
Use an exsisting program for Oxxxx if non exists write one into memory manually.

Ok Big progress was just made. I was able to send over some code, Excellent. But I got an error 087, Telling me input is not interrupted after 10 characters read. I/O unit or P.C.B. is defective. I think this machine is toying wit me...... i kno my lab top and connection cables are good so the IO device is not bad. Have you ever dealt with this.

[Al_The_Man]

The controller send a XOFF to the PC, if the PC ignores it and then sends more than 10 characters after the XOFF, you get the overrun error.
It looks like you PC software setting?

What setting would you recommend changing. As a dnc I am using NC link.

I have tried several different methods. I have tried shortening the program to just a few lines and have tried multiple setting changes. Two things keep happening: 1, I get alarm 087 Buffer overflow and I get a lot of gibberish that shows up after line 6 of the code or 2, I get a flashing input light in the bottom right of the screen. the only way I can get rid of it is to hit reset. Sometimes I get a lot of gibberish and sometimes I just get the correct program but only upto line 6.

I will keep trying changing things around and maybe something good will happen

I still have a couple of older DOS modem programs I use for trouble shooting, Qmodem and Telix, with these you can select different transmission types etc, the nice thing is they display anything coming back from the controller such as control codes etc.
So a XOFF can be seen as to when it is being received etc.
Sometimes overrun occurs on high baud rates, but up to 4800 should be no problem.
