Hi,

Currently my OPC simulator is down. Can anyone help me on this. I suspect something wrong with the security setting.

Anywhere more I need to check now.

Thanks.

It looks like you modified the user profile used by the Ignition OPC UA server.

Now you’ll have to go update the OPC UA connection configuration with the new username and password.
