CIP Safety with KRC5 Micro and AB Guardlogix: When does the SCID and SCTS values update?

    Hi,

    For our lab Kuka KRC5 micro robot controller with a KR3 D1200 robot, we are doing a simple setup where we basically want a safety Allen Bradley Guardlogix PLC to detect 2 light curtain, 2 safety stop buttons, 2 reset buttons, 2 magnetic sensor detecting if 2 doors are open, then make the robot do a safety stop. The robot controller and the safety PLC are connected through E/IP.

    The PLC logic is being handled externally but I am in charge of configuring the robot side.

    We have already configured the the safety local adapter and local adapter 1 in WoV, and the PLC is able to detect the controller.

    1. We don't understand why the SCTS values and SCID values did not change after our recent deployment with our safety changes (activated the Local Safety Adapter . They stay at the value 2024-01-18 which is probably the Kuka setup date.

    When we enter these values on the PLC side, they do not match and the SCID is thus not validated..Why?



    2. I still don't understand if I will need to map IOs for this setup. None of my robot programs will use the safety signals, we just want the PLC to shut down all possible motion, really. So do I need to look at mapping all the bits mentionned in the CIP Safety part of the Ethernet IP manual? Or is all of this already configured internally, and these info are just to be used by the PLC program developper?


    Thanks for any help!

    Changed the title of the thread from “When does the SCID and SCTS values update?” to “CIP Safety with KRC5 Micro and AB Guardlogix: When does the SCID and SCTS values update?”.

    Not sure about ABB PLC's, but if you use CIP in a SICK safety controller, you have to go into the SICK software and tell it to "write TUNID".

    I assume this is a similar situation. If ABB PLC sees the Kuka / was working before changes, It doesn't make sense to me that you'd have to change anything on the robot.
