I am trying to dnc to a fanuc-o control. I have been told that I have to enable parameter G127.5 . I have found G127.5 in the ladder but how do I toggle it on????????

[Al_The_Man]

AFAIK you set the machine to auto and turn on the DNC enable switch. Look in the ladder rung for G127.5 output and see what is needed to complete the rung. You need a complete highlighted path to get the G127.5 to highlight (turned on).

Thank you Al. I think I almost have it. Need to get past error 087 something to do with" though read terminate command is specified, input is not intereupted after 10 seconds."

That is Buffer overflow, what program are you using to download? Make sure it is set to use Xon/xoff are you using a three wire cable, or do you have a fully populated cable?

Using full cable same one I use to download and upload to and from memory. Software is pro-comm. x-on and x-off activated.do x-on and x-off pacing codes mean anything Thanks

We had a similiar problem with our fanuc 10M (buffer overflow), the problem was with character delay, we set it to 1 ms and the problem went away. I think the problem is with that the machine sends an XOF signal while the PC still keeps sending some chars which cause the receive buffer overflow.
