    Hi Guys,

    We usually hardwire safety signals (Dual Channel) from R30iB Plus to Allen Bradley GaurdLogix PLC.

    Due to the lack of availability of PLCs and components :frowning_face: , we are forced to look into other ways of doing safety.

    Has anyone worked EhternetIP Safety Option on Fanuc robots?

    If my understanding is correct, safety over EthernetIP will eliminate the need to hardwire safety signals between PLC and Fanuc controller. Is this correct?

    are there any limitations to using EthernetIP safety and IO Signals on a single ethernet cable?

    Thanks In advance.

    Kind Regards

    Yes, it will eliminate needing to hardwire safety signals.

    Yes there is a limitation to doing both Safety and Standard IO on the same cable. It is supposed to be possible to do so on a single cable by utilizing a DNS setup on the Robot. Otherwise you can separate them with Safety on 1 Ethernet port and standard IO on another with 2 separate IP addresses. Details are in the manual.

    CIP safety ist a certified extension of the standard (non-safe) CIP capabilities for CIP based networks (e.g. Ethernet/IP).

    Standard and safety communication is all going through the same physical connection. It ist only one ethernet cable required.

    Hi Guys,

    Thanks for the reply.

    I read the manual and we'll be separating safety and Standard IO.

    Do you guys have any recommendations on the byte size for safety? In the manual, it shows an example with 2 bytes. Is this enough?

    Thanks for your help.

    I think that's enough for the safety side.

    ¡ Hola

    podría ayudarme con el mismo problema, dividir los 2 puertos ethernet usando el CIP

    o sabes donde puedo encontrar ese manual de configuracion

    Give us some details on your setup, what you have tried, what error and issues you are having.

    configure standard Ethernet IP. I can already see it, it is in runing

    but I can not partition the ports, in standard and security

    menu > configure > I/O > ethernt IP > F3

    in the safety I/F status option : IDLE

    I want to know how to change the IDLE to Running

    have you guys seen scenarios where the robot looses ethernet every so often ? having some issues with the robot losing the ethernet and the safety bits drop because of it and stops the robot we have change the ethernet card on the robot cab 30ib and change the ethernet cable going to the controller but still happens it can run for hours without doing it and sometimes it does it every so many minutes

    Yes. We usually find its a questionable cable. But not always.

    A couple of times, it was the PLC sensing a dropped Estop from the robot. I put TOF timers on the estop bit and the problem disappeared. Its never been the robot detecting an estop from the PLC so I suspected something on the PLC or Stratix switch side.

    This is with the default safety RPIs set to 10ms from the robot and 20ms to the robot. Its possible changing these could help.

    All of these changes still satisfied the risk assessment.

    jstolaruk I can try it. but having an e stop signal from the plc to the robot don't make sence that it would loose communication because of an e stop. If I was to make the RPI what would you suggest I change them to?

    Something longer that won't impact the risk assessment.
