Safe communication between two KUKA robots

  • Good morning,


    2x KR10R1100six | PLC S7 1500 | WOV 4.0 | KSS 8.3.33


    I want to establish a safe communication between two KUKA robots KR10R1100sixx recently installed. Each robot is already equipped with :


    • 1x EK1100 | EtherCAT Coupler.
    • 1x EL2809 | HD EtherCAT Terminal, 16-channel digital output 24 V DC, 0.5 A.
    • 1x EL1809 | HD EtherCAT Terminal, 16-channel digital input 24 V DC.


    My idea is to add :


     1x PLC. Beckhoff
     2x safe digital input module ( one for each robot ).
     2x safe digital output module ( one for each robot ).


    The EtherCAT output of the PLC ( Beckhoff ) will be connected to the EtherCAT input of the coupler ( first robot ), and the EtherCAT output of the coupler ( first robot ) will be connected to the EtherCAT input of the coupler ( second robot robot ).


    The safe outputs ( robot 1 ) will be wired to the safe inputs of ( robot 2 ).
    The safe outputs ( robot 2 ) will be wired to the safe inputs of ( robot 1 ).


    I want to know your opinion about this solution for that application or propose me a better idea if there is.


    Thank you.

  • 1 question, Why do you need the safe communication between the robots? its hard to judge if you don't tell what you intend to do with it.

    Every problem has a solution, that isn't the problem. The problem is the solution.

    [font=verdana, arial, helvetica, sans-serif][size=2]Safety rated signals must use safety rated interfaces[/size][/font]


    [font=verdana, arial, helvetica, sans-serif][size=2]In case of KRC4 that would be X11 and X13 or ...[/size][/font]

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2
