hi,

I set my dnc software to receive with 2400 baud, 2 stop-bits, 7 data bits, EVEN parity and it works good, but when i try to input any program with the same definitions the machine gives me the alarm 087, can someone help me?
The parameters of my machine are 0005:00000001 and 068: 2400.

best regards

I Believe that is RS232 signal DR signal incorrect, are you using a three wire cable with the handshake jumpered out? If not, try that.
Go to the Cadem.com site for the cable and parameters.

087 alarm = When entering in the memory by using RS232 interface, though the read terminate command is specified, input is not interrupted after 10 characters read.

Hope someone here can help you understand what that means.

Maybe you ro somebody can help me. I don't know how to send info in to or out of my 3T to a PC

I tried, and erased all the programs that I had manually entered. Looking forward to reloading them from what I saved when creating on the PC.

Are you set up on your PC for XON/XOFF, software handshake?

Your DNC software isn't responding to the Xoff handshake fast enough. The 087 alarm means that the Fanuc filled up its buffer, then sent the Xoff to your PC, but the PC kept sending data and overflowed the Fanuc buffer.

If your DNC software is set to handshake with Xon/Xoff, then try this trick: (this is for Windows XP, so other versions of Windows may be different)

Right-click on "My computer"
Click "Manage"
Click "Device Manager"
Double-click on "Ports (COM and LPT)" to reveal the list of ports
Right-click on the COM port you are using
Click "Properties"
Click "Settings"
Click "Advanced"

Set the "Transmit buffer" slider control all the way to the LEFT (lowest setting)

Click OK until all menus are closed.
Open your DNC software again and give it a try.

Hi Al
Yes the PC is set for XON/XOFF

I have a program that I really like. From dnc4u.com. It has a wizard that will analyze output from a machine and store it. I used it to be able to talk to an old Anilam control on a mill, worked like a charm, after 2 techs tried, with other programs, for 2 days without sucess.

This is the first time that I am attempting to connect a PC to this Fanuc 3T on a Wasino lathe. I have owned the machine for several years and have always just used the machine keyboard to manually enter programs. In the parameters I have set the I/O function to ON and selected the RS232 com port on the control.

Now I just need to know how to tell the control to send info to the PC.

Appdreciate your response, I didn't think I would see anything here for a day or two.

Try our PC-DNC Editor. You can download it from our website at:

http://www.sub-soft.com/download/Edi...itor_3.4.0.exe

The operator's manual is also downloadable from:

http://www.sub-soft.com/download/Edi...tor_manual.pdf

In the PC-DNC Editor, go to the I/O menu, click "Configure IO device", then set 2400 baud, 7 data bits, 2 stop-bits, Xon/Xoff handshaking, ASCII even parity, LF as an End-of-block.

On the "Advanced" page, be sure the checkbox marked "Handshake using device driver" is checked. If your programs have percent signs (%) at the beginning and end, leave the "Leader" and "Trailer" boxes blank. If your programs DONT have percent signs, put "LF" in the Leader box and "%" in the Trailer box. Click "OK" to exit the Advanced page, then click "APPLY" to save your changes.

To send a file, open it with the File/Open menu, then click the "DNC" button, or click "I/O", then "Send File". At the prompt, select "Wait for Xon", then go to your Fanuc control, put it into EDIT mode, turn OFF the memory protect key switch, then press INPUT to read the program.

[ardor]

OK, now I have tweaked the buffer setting, set software to wait for XON.

Now I get 086 alarm, "I/O or DR turned off". I have turned I/O on (it was set to off). I have read thru all the parameters listed in my manual and don't see where to turn DR on.

[Dan Fritz]

The I/O bit should be zero ( 0 ). That bit is not the reason for your 086 alarm. Here are the parameters for 2400 baud 2 stop-bits:

First parameter page:
TVON = 0
ISO = 1
I/O = 0

parameter 005 1 x x x x 0 x 1
parameter 068 2400

The bits marked "x" in parameter 005 are used for something else. Do not change these bits. The bit on the far right is for stop-bits (a "1" is for 2 stop-bits, and a "0" is for 1 stop-bit)

Parameter 068 can be set to any legal baudrate between 50 and 9600. I recommend 2400 or 4800 for this control.

The baudrate setting and the stop-bits setting must match your DNC software.

The DR (Data Set Ready) signal is on pin #6 of your Fanuc's serial port. The Fanuc wants to see a "High" or positive voltage signal on this pin. It also wants to see a positive voltage on pin #8. We always put a jumper on the Fanuc end of the serial cable between pins 6, 8, and 20. Pin 20 is an output from the Fanuc, which will hold both pins 6 and 8 high.

Here's the cable I recommend for the Fanuc 3

Fanuc 25-pin side ------- PC 9-pin side
pin 2 ---------------------- pin 2
pin 3 ---------------------- pin 3
pin 5 ---------------------- pin 7
pin 7 ---------------------- pin 5
pin 6 ----
pin 8 ---- <-- jumper these 3 pins together
pin 20 ---

[ardor]

Apparently the DR off means the control is not seeing anything from the PC.
I get the same alarm with the null modem cable attached or not attached.

I tested the cable on another control and it works. So data is getting to the port and no further. Either the control doesn't have the optional communication capability or the capability is borked. Since the RS232 port is on the control I'm probably having a problem on one of the PC boards.

We will see what Fanuc has to say tomorrow.

Dan

Thanks

I can change parameters on the 1st page, but not on next pages.
0005 is set to 00000001
0069 = 1200 PC is set to 1200 & 2 stop bits.

That cable is way different than what I put together.
The diagram I used is for Null modem cable, without handshake.

It looks like this.

25 pin----------9pin
pin 2----------pin 3
pin 3----------pin 2
pin 4
pin 5 <----------------4 & 5 jumpered
pin 7----------pin 5
--------------pin 1
--------------pin 4 <------- 1,4,6 jumpered
--------------pin 6
--------------pin 7
--------------pin 8 <------- 7,8 jumpered
pin 6
pin 8 <---------------6,8,20 jumpered
pin 20

I'll put one together from your diagram. When I do, pins 7 & 8 on the 9 pin will still be jumpered, OK?

Hopefully I can get it right & not be calling Fanuc.

I posted #10 before I saw your #9

[Dan Fritz]

Your cable shows pin 2 on the Fanuc tied to pin 3 on the PC and pin 3 on the Fanuc tied to pin 2 on the PC. This is backwards.

The Fanuc uses pin 2 to transmit data, which must be tied to the receive pin (pin 2) on the 9-pin PC plug.

The PC sends data on pin 3 of the 9-pin plug, which must go to pin 3 (receive) on the Fanuc.

Pin 7 on the Fanuc is signal ground, which is tied to pin 5 on the PC.

Pin 4 on the PC is the Data Terminal Ready output. Jumpering this pin to pins 1 (CD) and pin 6 (DR) is the equivalent to jumpering out 6-8-20 on the Fanuc side. Usually though, the DNC software will not require this. There's no harm having these 3 pins jumpered.

You also show pins 4 & 5 jumpered together on the Fanuc side. This is OK, but it defeats the hardware handshake when the Fanuc is sending. Normally, I like to wire the cable so if the PC is not ready, the Fanuc CAN'T send any data. With your 4-5 jumper, your Fanuc will be able to send data even if the PC isn't ready.

Besides the pins 2 & 3 issue, I see nothing else about your cable that would prevent it from working. As you can probably tell, there are about 10 different cable configurations that will work, but some are better than others.

Let's suppose for a moment that the pin 20 (DTR) output on your Fanuc is blown. That would mean that your 6-8-20 jumper would not defeat the 086 alarm, but this cable configuration would - because it uses pin 4 on the PC side to hold pins 6 & 8 high on the Fanuc:

25-pin Fanuc ------ 9-pin PC
pin 2 -------------- pin 2
pin 3 -------------- pin 3
pin 5 -------------- pin 7
pin 7 -------------- pin 5
pins 6 & 8 --------- pin 4

(no 6-8-20 jumper needed on this cable)

THANK YOU Dan.

That cable did the trick.

Hi,

Check or contact the next link, he has also a Takisawa with Fanuc 3T but don't know which model.
