data exchange through controllers

[potis]

Hello to all. we have 2 nx controllers and we would like to exchange data with each other but without using the digital i/o of them because we would then must reserve a lrge number of i/o meaning additional xoi cards and no bus card are present either (devicenet,profibus etc) Is there any other way to echange data f.e. by using the ethernet port?i would like to read some i/o from the other controller or a variable. any suggestion is welcome

Unfortunately there is nothing to help you . I heard that dx was supposed to have that feature though. I believe it was called moot-net ??

Good luck

Since i have placed the controllers up and down i thought of how about making iot master/slave? this would solve all my issues but then comes the big question "how do you make this?". i have worked with master/slave on xrc and nx but do not remember cabling. any idea?
one the first robot is a EA robot with 3 external axis (1 base track and 2 positioners) and the other is A ES robot.

Well you could make your system a dual... this would involve running a linking cable between the two cabinets and modifying some rotary switch settings as well as it would require initializing your robot system.

Your current jobs would need to be re-programmed, or at least some clever offline manipulation.

By linking them together, you would be controlling two robots from one teach pendant.  Both robots would share the same I/O system

Hi,
I think you will need to make your cabinet into a slave before you link it to the other master. Also i guess the CPU & rack will need changed from a master to a slave because two masters not possible. Then it is just a case of adding a internal bus cable/supply from master cpu to slave and then reconfigure.

Hope this helps.

is there any guide that i could follow? which link cable would i need? which rotary switches should be changed? how i will disable the pp from the slave? the nif board at the slave will it act as an aditional xoi card (meaning 40 i/o) or as the standard (meaning 24 i/o). what about the X18 safety boards? some drawings or pictures would be really helpfull.
with this strategy i will solve all my problems.

Not sure of any guidesm or manuals? but you will defiantly need additional parts/cables so you will need to speak to Yaskawa.

You will need cable to draw power from master NTU to slave NTU rather than the master transformer. The Master CPU back plane/rack that you are converting to a slave will need to be changed to a slave rack, this will not have the X18 connection. There will be an additional cable to connect the master & slave back planes together as well as a bus cable.

Sorry for vague info but believe i'm pointing you down the correct road?

Hope this helps.
