Turning on OPC UA on a Siemens 840D Solution Line

Make sure that you have the option "Access MyMachine /OPC UA 6FC5800-0AP67-0YB0" activated (Startup->Licenses).  Note: if your machine is an embedded Siemens control with an overlay from another machine tool builder you will need to reach out to that tool builder to activate the OPC UA option as it may interfere with their customizations to the control.

Activate OPC UA License

FIG above:    Activate License

Start the OPC UA configuration in area [Startup]->[Network]->[OPC UA]

Configure OPC UA at the controller

FIG above:    Configure OPC UA


Note:  The steps below are typically auto-filled when the license is activated.  Just verify they have been populated and that the Activate OPCUA option has been turned on.

IP Address is automatically set according to the HMI configuration, 

Enter 4840 in field Port (1)

Enter a username for the Administrator (2) of the OPC UA server on the controller, such as OPCUAUSER

Enter and confirm the password for this user (3). such as OPCUAPWD1

Check ‘Activate OPC UA’, click [OK].

HMI Operate may need to be restarted for the changes to take effect.

Important note: Please ensure that the date and time on your HMI is correct, otherwise certificate based OPC UA authentication does not work!
