Need Help!- Controllers

[Russell@Iscar]

Hi Folks,
Is there anyone with a detailed step by step for setting the correct parameters in these controllers to allow for send/receive to/from between our PC and each controller, 10M, 11M, 15M, 16M, & 160M through our multi-port DNC box. We have each machine defined on the PC with what I believe are the correct set-up parameters. But we are unable to send/receive correctly to/from each machine. We have DB9F to RJ45 on the DNC box going to RJ45 to DB25M to each machine.

Have you tried attaching an RS-232 mini tester to the DB-25 connector to see if there's data coming thru when you send from the pc? What software / multi-port box are you using?

Are you getting an alarm when you try and send or receive?

Typical settings
Format ISO
Parity Even
Data bits 7
Stop bits 2
Flow control Xon/Xoff

Stevo1,
Yes. The alarm code is: SR821 CD OFF (1).
While the Fanuc rep was here we got this one: BG821 CD OFF (1)
The typical settings you stated are what we have.
The web link you provided (http://www.kfasllc.com/rs232_cable.htm) gives the pin connections. On our DB9 female we do not have the 1,4,6 jumper or the 7-8 jumper. We do not have these pins connected at all. We cut them and are not using them. Is there any significance to that?

Russell, I don't remember providing this weblink.

The web link you provided (http://www.kfasllc.com/rs232_cable.htm) gives the pin connections.

Anyhow the alarm your getting has to do with monitoring the comm switch. I don't believe that it is normally used but if your getting the alarm then something is not correct. I suspect that your pinout may not be correct or your settings on the PC. I have attached the pinout that I use. Compare these and let me know what you find.

Stevo,
I am sorry. I guess it was the private message I received from the fanuservicetech which provided the web link. Anyway, I have a cable without RJ45 connections. It is a DB9F to DB25M. It is pinned the same as the pin outs on thje diagram in the web link except we do not use the 1,4, & 6 jumper or the 7-8 jumper. I tested with one of the machines using an 11M controller. I was able to send/receive to/from with no problem. However, the web link also provided parameter settings for the controller and the PC, and even though our settings were a little different, it worked. Now I have to try this on the other machines to see what happens. I will get back with you if I need to.

The CD alarm is happening because you don't have a signal on pin 8 of the Fanuc's 25-pin connector. Pin 8 is a signal called "Carrier Detect", and it's really meant for use with a MODEM (the carrier signal that connects one MODEM with another). Also, pin 6 (Data Set Ready) must be on as well, otherwise you'll get a "DR" alarm. This is why the recommended cable for a Fanuc shows a jumper between pins 6, 8, and 20 on the Fanuc side of the cable. Pin 20 is an output (Data Terminal Ready) that the Fanuc turns on when it opens the port, and this "high" signal can be used to hold pins 6 and 8 high.

If you jumper pins 6, 8 , and 20 together on the Fanuc side, that should prevent the CD and DR alarms. With most DNC software, there is no need to jumper pins 1, 4, and 8 on the 9-pin PC side. These are the same signals as pins 6, 8, and 20 on the Fanuc side, but most DNC software doesn't care about the DR or CD signals, so they are just ignored.

If the Fanuc throws the CD or DR alarm after the 6-8-20 jumper is in place, it may be because the Fanuc is trying to communicate with a DIFFERENT serial port. Most Fanucs have more than one serial port, so if the parameters are set to use a different port from the one you're plugged into, it will just throw a CD or DR alarm regardless of your jumpers.

In some very rare situations, the Fanucs serial port may be blown (no output on pin 20 or bad inputs on pins 6 or 8). In that case, you'll get CD or DR alarms no matter what, and only switching to an alternate serial port or cirucuit board surgery will make it work.

Sounds like your in the process of inventing your own DNC system. There's a lot more to it than what most people think. We've been doing nothing but DNC for 30 years, and we're still learning. Good luck!

Fritz is correct, on my detailed pinout CD runs on pin 8. Even if you are not using the RJ45 jacks the pinout is the same for just straight wire DB9-DB25. I have this cable and the RJ45 cable. You have to jumper the 6,8,and 20 pins together.

Sometimes getting a comlink going needs a bit of DNC knowledge.

Hi Dan,
Thanks for your input. I have the 6, 8, & 20 pins jumpered together on the Fanuc side. I am getting this alarm: BG806 Device Type Mismatch, when trying to send a file from the PC to the machine. Do you have any insight as to what may be wrong? I really appreciate any help.

What make & model CNC controller is this "BG806" alarm happening on?

[Russell@Iscar]

Hi Dan,
The BG806 alarm is coming on a WAIDA with 15M controller.
