Fig 46 Component Services window
Double click the Component Services and then expand the structure below it. You
can now operate at machine (recommended) or at task level.
In order to set the DCOM security at machine level, right click “My Computer” and
select “Properties”. In the new window (Fig 47), click the “COM security” tab and
consider both “Access Permissions” and “Launch and Activation Permissions” sec-
tions.
Here, select “Edit Limits” and “Edit Defaults” (both of them are required), and add
the user (“MM8000_PROC” user on the OPC server PC or the OPC server identity
user on the MM8000 PC), setting the “allow” attributes for all positions.

The “Edit Defaults” settings described above will affect all software tasks. Alterna-
tively, you can enable users at individual software task level (note that the “Edit
Limits” configuration is required anyway).
In order to do so, expand the list of tasks in the “DCOM Config” node, and locate
the task: “MM8000server” on the MM8000 PC (Fig 48) or the OPC server name on
the OPC server PC). Right click the task name and select the “Security” tab.
