Communication between Roboguide and PLC Siemens with ethernet

    Hello everyone,

    I'm trying to communicate between a real PLC S7-1200 and roboguide with an Ethernet communication and I need help if possible. I've looked around and it seems possible but mainly done with Alan Bradley PLC.

    I've searched in this forum and around but i didn't find a subject that is clearly related. Sorry in advance if I missed it.

    Below is a list of the things I've done in order to make it run :

    • The IP adress of the robot identical as my computer 192.0.0.12 / 255.255.255.0 without any gateway and my PLC is 192.0.0.141 and responding to ping.
    • R784 / R785 + Variable EIP_ENA_IO = 1
    • IO ethernet IP 32 IN / 32 OUT in order to use 64 bytes of communication. Connection1 enabled as adapter and status online. Not responding to ping in this menu.
    • DIO and GIO, I've declared few bits on the rack 89 slot 1 but not the 64bytes which shouldn't be a problem if i'm not wrong.
    • Below is the configuration of the LCCF DB :
    • IP Adress 192.0.0.12 / vendoridentifier : 356 / producttype : 12 / productcode : 4 / revmajor : 3 / revminor : 1 / assemblyinstance : 100 / packetinterval : 100ms
    • conPointOutpuidentifier : 151 / size : 64
    • conPointInpuidentifier : 101 / size : 64
    • configDarasize : 0

    Do you see something that is missing or wrong in this ??

    Thanks in advance for the help !

    Approved the thread.

    I've never tried to connect Roboguide to physical PLC.
    However, I would not set the Roboguide robot IP address same as PC physical port address, as this might be an address conflict.
    I would set the robot on the same network, but different from the PC IP address.

    Do it well right away. It will become bad by itself.
