    I missed these from the manual when I posted the other pages.

    serial-interface.jpg


    The illustration in the manual reads

    Interface Com1
    Protocol RTS-CTS
    Baud 9600
    Stopbits 1
    Parity Common
    Dat byte 8
    Xon 11
    Xoff 13
    End transmission ???cannot read it???


    Ticked boxes on right 3,4 and 7

    I edited the protocol and the EOT to 18 and see no change.
    Still captures just fine, just no "end of file" like I normally get from other controls.

    Preface: I'm nearly illiterate in Siemens CNC.....

    I wonder if the EOT is a hex value? The XON and XOFF fields are noted as hex. Seems logical that if Siemens was going to use a hex value for EOT they would have noted it as well.

    If it was just looking for literal text to designate EOT then maybe you have to enter whatever you are going to transmit as EOT (usually a %).

    Another thought that might bear looking at is that hex 1c is deemed "file separator" in my ASCII chart....

    Thanks Jules, No experience in that before, but I knew that there had to be some cheat sheet somewhere for those values.


    Vanc - Keep in mind that the 11 and 13 in my control are apparently Siemens defaults.
    However - Mr. Thames has the same values.


    Thames - Where doo you come up with 1a from?

    Even the 840D typically has only about 8mb of memory up front in the CNC folder.

    Most machines come configured by the MTB with a "LOCAL DRIVE" directory that runs off the hard drive.

    You may be able to map your own "LOCAL DRIVE" if you look under the HMI settings.

    A couple more pictures to add to the thread, may be of use when this thread comes up again with a search.

    My lathe is 2002 marked as - Siemens 810D/840D

    This is the RS232 screen default are slightly different than the manual pages I posted above.
    Not use this so this must be factory default for my machine.

    Confirms End of Transmission as 1a on my control.

    Now to see if I can figger out how to load directly to the CCU, or to drip feed it. (or both)

    I would think that having the % finish thingies working would be helpfull in this tho...

    On my 840C control I have to put the following end-of-file character at the end of a g-code file in order to transfer to the CNC via RS232:

    

    I'm sure there in a keyboard code that will insert that character, but I just have a text file with that character that I copy and paste on the end of the program.

    Default Good News!

    Worked with a voice from Siemens today, and we got it figgered out.

    My control IS able to drip feed directly from the hard drive, and the HD seems to have way more headroom than we will need!



    It took a while to find the required keystrokes/routing to get there, but it does not appear to be an optional feature.
    My Opp Manual did not give nearly enough info to get there, but we got it now....


    Thanks for all who tried to hep!


    Still not gotten the EOT thing all under control, but it's not that big'a deal.
    If it works - super, but if it doesn't - I can find someone that can hit the "done" button....

    As a precaution it might worth getting a Siemens engineer on-site to have a look at your FIFO buffer settings, baud rate, 'and all'. Just to make sure that ctrl is able to keep up with that particular 3D part program. Depending on how its programmed (e.g. linear lines, 0.01mm tol, etc)

    3D scrap$ are not cool
