DR signal off via ethernet?

[H234]

I have a Puma MX2000ST and I am having issues sending programs to the control via ethernet. I followed a guide I found on the forums for setting up FTP with the Fanuc control and its almost working...

I have the IP addresses setup on a laptop as well as the control where the control can see the host FTP server as well as the programs that reside on it. When I use edit mode -> program -> read -> execute I get the error "DR Signal Off". This leads me to believe that it is trying to use the RS232 port rather than the ethernet. Perhaps I am simply using the wrong menu option to read programs from the FTP server or the I/O Channel is incorrect. I have tried several different channels to no avail.

Any help is greatly appreciated.

Thanks,

Jonathan

Have you tried 9?

Also, check parameter 0110 bit 0. If it's 1, then input and output are set separately in parameters 20 - 23.

Here's a Doosan/Daewoo .pdf document describing how to set up the Ethernet.

I changed the I/O Channel to 9 as it suggests and I am now able to PUNCH and the program is successfully written to the laptop. However, whenever I try to send a program to the control I get error 071 Data Not Found. If I send a program that I just received from the control, it flashes compare and finishes with no error. If I change a single line I get error 079 Program Verify Error because the two versions are different.

It seems that the communication between the laptop and the control are working, but now something else is going on..

Are you typing in a filenumber (NOT a program number) then pressing READ?

Not sure what control is your MX but the following procedure suits Fanuc 30 series:

To download programs from PC to machine tool
· Select EDIT mode
· Press PROG DISP
· Press FOLDER screen key
· Press OPRT screen key
· Press DEVICE CHANGE screen key
· Press EMB ETHER screen key
· Press + screen key
· Press REFRESH screen key
If the file is displayed as a file (i.e. TEST.NC)
· Press READ screen key
· Cursor to program required
· Press F GET screen key
· Press F SET screen key
· Press EXEC screen key

I can say that I am using the file numbers to load the program as you suggest, not simply the program number. When I do access a program, I can confirm it was read because the FTP server says it was successfully accessed and read. I believe that the major source of my problem is not having the edit enable key. Someone managed to hide or misplace it and I am trying to track it down. Thanks for your help
