Using RS232 on a fanuc 10m

[davidrvalencia]

Hi, I have a kitamura mycenter0 (1985) with a fanuc 10m with a tape drive and rs232. I want to drip feed or do direct downloads/uploads of codes from my computer. I have a cable with the correct pins, I just have no idea on where to start when it comes to telling the machine what to do to talk to my computer.

Thanks in advance

Are you able to transfer programs to the machine from your PC? If so, DNC is achieved with this control by using TAPE mode selected via the mode selection switch. Then its PC software specific whether the same Send function is used to DNC as used for normal transfer of program to machine, or if there is a separite DNC mode to use.

In the majority of good DNC software, you can set the PC ready to send and waite for the machine to initiate the process. Then with the machine in TAPE mode, cycle starts is pressed to begin.

All functions such as single block, feed hold, block delete, etc. all work as per normal as if running the machine form a program held in memory. About the only limitation is if SUb programs are being used; these have to be stored in the machine's memory, but will be called by commands executed from the DNC stream.

If you don't already have communication established between the machine and PC, then you will have to check and make sure that the following parameters are set correctly as indicated:

#0000
Bit 0 = 0
Bit 1 = 1
bit 2 = 0
Bit 3 = 1
bit 4 = 0
#0020 = 1
#0021 = 1
#0022 = 1
#0023 = 1
#5001 = 3
#5110 = 3
#5111 = 2
#5112 = Baud Rate (10 = 4800) Starting point

The PC software settings will be:
Handshake Method = Xon Xoff (software handshaking)
Data Bits = 7
Stop Bits = 2
Parity Bits = Even
Baud Rate = 4800, or whatever the machine is set to.

Just to make sure your cable is correct, the following pin out should be used:

My information is that earlier FS10 controls did not all have a TAPE mode; if so, the ladder (if present) may have to be modified or the TAPE mode input hard wired.

You are most correct. Most of the System 10's did not have a "TAPE" mode on the mode selector, but the System 11 and 12 did. Usually Fanuc would've had to install a DNC type function in the field. Some DNC companies could do this as well.

Thanks for your replies, I just got back in town so I havnt had time to work on the machine, I am working on it now and I checked the wire and parameters and they are all right. The mill has a rs232 25 pin plug on the door next to the tape reader so im assuming it is for DNC, and that is what I am using.

I do not have a TAPE mode, i simply have a switch by the tape drive saying "Tape Reader / Ext System"
What mode should the machine be in to receive the data? Memory, MDI, Edit? Also I am using NCnet Lite as the DNC software.


I have heard from other sources also that hardwiring it into the tape drive could help, if this was require how would I do that?
