FANUC RJ3 DEVICENET CONFIG

    Hi Guys, I have a m6ib with rj3 controller and handling tool, I am in Argentina and I have purchased the update to Arctool with the devicenet license from Fanuc. I have installed the update without major complications but the devicenet board does not recognize. The devicenet module has four green lights on the top and two red lights on the dotherboard, power one and hlth. The problem is that the software does not seem to recognize the board. Do any of you know what the initial configuration is for devicenet? Do I have to enable some variable or configure some port?

    Thanks

    Approved the thread.

    Red power LED usually means the 24VDC has not been connected to V+ & V- at the DeviceNet connector.

    Red health LED usually is the board is not configured in the software.

    Are you using this to connect to a Lincoln welder (ArcLink) or to a PLC or I/O?

    There are several generations to the DeviceNet cards, can you post a picture of yours to help identify?

    Thank you very much for your response, the devicenet board I have is model A16B-2203-0190/07B. The welding source is the Miller Auto Axcess 300 DI, perhaps because I am completely ignorant on the subject, I interpreted reading the Miller manual that the source provided 24V, does the network always have to be powered with 24V? I attach an image of the devicenet board, I was reading the manual, configure the dotherboard jumpers. If you can guide me on the configuration it would be very helpful.~lg-FANUC-DEVICE-NET-BOARD---USED-(A16B-2203-0190-07B).jpg

    A16B-2203-0190 is the part # for only the full size motherboard, Fanuc had different numbers depending which PC104 daughterboards were installed.

    Hard to tell but DeviceNet daughterboard looks like the 5136-DN installed in position 1 (Rack 81). Make sure the address dipswitches at the back of the daughterboard are all set to 'OFF".

    Did you receive any manuals from Fanuc when you worked with in a previous post found >here< ?

    Hi again.

    As I understand it, the dotherboard is the SST-DN4-104, I don't know if it has a sub_code, I would have to disassemble it and see.

    It is in rack 81 and the dipswitches are all off.

    Fanuc has sent me a devicenet manual but I can't find anything that could be causing the problem.

    I have some doubts, as I understand the devicenet networks require external 24v power but the miller supply delivers 24v through V+ and V-, will it also be necessary to power with external 24v? Wouldn't this generate a short circuit?

    On the other hand, the Mac ID is set to 1, could this be generating a conflict with the communication of other parts of the robot?

    I can't find the manual that Fanuc sent me in a timely manner. It was a fairly generic manual.

    I didn't buy the devicenet motherboard along with the dotherboard from Fanuc, I bought them used and tested on eBay.

    I thought I mentioned, maybe I didn't, that the health light is red. Do you think there may be an incompatibility between the rj3 controller and the DN4 dotherboard?

    When I ordered the new software and the devicenet license from Fanuc, I talked to them about the motherboard model but never about the dotherboard.

    I missed the Health - sorry.

    I don't recall ever using a DN4 in an R-J3, always the DN or DNP and maybe/maybe not the DN3. I assume it will work but not sure.

    If you have 24V at V+ & V-, I would still expect the Power LED to be green.

    Searching A16B-2203-0190 online shows used ones with older DeviceNet PC104 cards relatively cheap.
