    Default ps error 128 trying to DNC

    I have a milling center with a Fanuc O-MD control and I'm having problems to DNC run a program from the computer.

    I select MEM-DNC and press the Cycle Start key and I get LSK flashing in the lower right corner of the screen.
    When I start transmitting from the computer, the first two lines go through and then I get a ps 128 alarm. First line is of code is the % character.

    From the OFFSETS screen pressing the OUTPUT-START key I get all the data sent correctly to the computer, so I assume cable and RS2332 parameters are correct.
    Is this assumption correct?


    Any ideas?
    Please

    ...DNC drip feeding Fanuc 128 Alarm "ILLEGAL MACRO SEQUENCE NUMBER" ...sounds like your program has Sub Programs in it or Macro Calls which I don't think is allowed using an external PC for running a program. one more thing to check use XON/XOFF
