Username/Password Authentication - GE PACSystems RXi User Manual

13.3.2 Username/Password Authentication

You enable OPC UA server Username/Password Authentication by enabling RXi controller
passwords. Machine Edition is used to enable controller passwords. To access this setting
using Machine Edition, open the RXi hardware configuration in the Project tab within the
Navigator, expand the hardware configuration, and select the controller. Double-click the
controller tree node to access the controller-specific hardware configuration settings. Select
the Settings tab, then set the Passwords parameter to Enabled (refer to screenshot below).
The RXi OPC UA server password is the same as the RXi controller password. Controller
passwords are set using the Machine Edition commands Select Target  Online
Commands  Show Status, which opens the controller status dialog box. Select the
Protection tab, click the Passwords button to set the passwords for the different access
levels (refer to the screenshot below).
The RXi OPC Server assigns usernames to the different access levels. The usernames that
correspond to the different levels are as follows:
Level 4
Level 3
Level 2
For example:
RXi Level 2 password = MyLevel2Password
The OPC UA Client would use the following username/password to establish a
connection.
Username = OpcUserLevel2
Password = MyLevel2Password
