The SLS 1508 logic solver card and logic solver are configured in different places in the DeltaV Explorer. After you create the logic solver assign it to the logic solver card.
The Logic Solver now appears in the DeltaV Explorer hierarchy under a SIS Network Domain in the SIS Network, but the icon is grayed until it is commissioned to a Logic Solver card.
You can also create a Logic Solver by dragging and dropping a Logic Solver card from an I/O subsystem onto a SIS Network Domain (which assigns the Logic Solver as well). Right-click the Logic Solver and select Properties to complete the properties information.
