best way to transfer dec number to plc

  • Hello,
    What is the best way to send a dec number value from a fanuc lr mate 200 id to a allen bradley
    5000 series plc using ethernet. I am wanting to tell the plc what number ring that the robot is picking
    (1-48). Thanks for the help.

  • You could use a group output to do it, and then set the GO in your program, and decode it on the PLC side. This would be the easiest


    Another way is to directly read it out of the robot's register, using an explicit message. The Fanuc EtherNet/IP Setup and Operations manual has very detailed instructions on how to do it.

    Check out the Fanuc position converter I wrote here! Now open source!

    Check out my example Fanuc Ethernet/IP Explicit Messaging program here!

  • For slow me. I've got that ethernet/ip is rack 89. Slot number is what? startpoint is what Size I've got, I think.


    I've got 18 16b registers transferring between Robot and ControlLogix. 1st output reg is O0100.


    The first 8 are used for digital I/O.
    9 is utilizing a size of 5 as it's a small number transfer.
    I want to setup up groups for 10-18 so I can transfer numeric data over.


    The Ethernet setup and operations manual is great, but says to see the
    "Applications specific Setup and Operations manual" for I/O configuration. Wish I knew where THAT was :smiling_face:

    The slot number is the connection number, as listed in the I/O>Etnernet/IP menu.

    No. The connection size is 18X16=288 bits in your case.
    The start point is specified in the DI/DO, UI/UO, AI/AO configuration, and assigns the location of the specified group of consecutive I/Os within the connection data packet (that is within your 288 bits).

    Each robot comes with application-specific software package. Fanuc calls them tools.
    For handling robot, the manual is "HandlingTool Setup and Operations Manual" (MAROBHT8104121E for R-30iB).
    There are also welding, painting, dispensing, and some other robots.
