How to configure OPC-UA in OfficeLite DeviceConnector

    Hello everyone, I am new to the world of kuka robots. I would like to understand the basics of using the OPCUA protocol provided by DeviceConnector in Officelite. Starting from the beginning I have read the manual but I have the following doubts:

    - The manual pages show the UaExpert interface but I don't understand if I have to install it on the windows machine or inside the VM where Officelite is. I tried to install it but using the default credentials specified in the manual (user: OpcUaSecurityAdmin, pass: kuka) I get an error: ‘’BadUserAccessDenied’ was returned during ActivateSession’

    - Is it necessary to save a configuration in order to use OPCUA or do I have to write lines in KRL to initialise the server?

    I'm using Kuka KSS 8.6.12 and KUKA.DeviceConnector 2.1. Thank you in advance for your help.

    had on occasion used OPC server but never DeviceConnector. UaExpert is a OPC client.. and a massive one at that... (like Matrikon OPC UA). anything installed on KRC or OfficeLite should be light on resources so this is not something i would even consider putting there.

    i only used UaExpert/Matrikon to test connections while developing own client.

    Thank you for your reply, however I have also tried with a small script in python to log in and the program returns the same error ‘’BadUserAccessDenied‘ was returned during ActivateSession’ I have also tried logging in with other users like OpcUaOperator or OpcUaObserver, always with default password ‘kuka’ but I always get the same error, logging in as Anonymous instead the system (both python and UaExpert) returns another error ‘BadIdentityTokenInvalid’ was returned during ActivateSession .

    yup i remember those from working with OPC UA server... one had to login... anonymous would not work at all. i may try looking up my notes on this in the evening. if i recall correctly Matrikon was a tad better than UaExpert in terms of troubleshooting and establishing connection.

    if you never used OPC, you may consider also trying some demo server... and check KUKA.OPC server manual (even though you do not have that option on your robot). this should make things clearer and give you chance to try things out - see how client works before you start wrestling with making it work with the robot.
