PC -> Robot ethernet communication protocol

[Dragonfly]

Hallo Fanuc specialists

I am looking for information about the ethernet communication protocol.
Normally i work with motoman and they have a manual that describes the ethernet communication protocol between the PC and Robot.

Is there some sort of manual of the RJ3 controller from Fanuc.

Its like this:
We have created vision software that can handle with 3d images and give XYZ Rx Ry Rz.

I want to write a protocol to control the robot, send variables and start and stop the robot, and all this with the ethernet protocol.

I already found this manual ROBOT-PC COMMUNICATIONS MACROS. But thats from the Robot to the PC.

I know there is software PCDK but you have to buy it and other stuff. If there is a manual about the PCDK with the communication described  that's also perfect.

I know its not allowed to ask for manuals so maby you can contact me with a PM

( The manual that discribes the motoman communication is Data Transmission Function Manual )

Thank you very much

FANUC will not disclose anything about the PCDK protocol because you could really screw the machine up if a mistake is made.  Its very low level (I helped develop it).  Also, I don't know if a way to listen on a port using KAREL.  There may be a potentially free way to transfer data using the web interface but I was not involved in developing that interface.  I seem to recall a mechanism for setting variables from web pages using FANUC ActiveX controls that used to be given away.  There may be a way to fool the web server into transferring data using these controls.  Is anyone familiar with the web interface?

Hi Dragonfly you have been succeed with something??

I was looking if Fanuc give more information about ethernet comunication for RJ3... with motoman they give all information of the protocol. It will be very nice the same for Fanuc.

Many thanks
