Kuka Robot Software 8.5.8
Kuka Controller KRC4
Profinet Version KRC4-Profinet_5.0
The issue I am having is I have a Kuka robot that is using Profinet communication to send IO back and forth between itself in and the PLC. The PLC recognizes the device and communicates over safety this verifies that both he PLC can see the Robot and the Robot can see the PLC. When I start to map the IO in Work-Visual 6.0 it starts to have troubles. Once the IO is mapped to its corresponding output I have a KSS00099 “Error on reading /writing PNIO-CTRL” and a KSS11000 “Device ac3 could not be started within 20000ms”. These errors pretty much mean that it does not recognize the Profinet device and there is an error transmitting the IO back and forth to between the two devices. This would be caused by a configuration error on the Profinet setup. Well here is where is gets weird I have multiple Kuka robots one of them is communicating fine with the device and one is not. Both are set up the same minus address and naming convention.
If you have any idea to why this would be the case let me know what you think. I attached a screenshot of the Profinet Setup
