Assign an I/O reference for an input function block in an SIS module

This assumes that the SIS module is not assigned to a Logic Solver.

  1. Right-click the input block in the function block diagram.
  2. Select Assign I/O → To Signal Tag.
  3. In the I/O Properties dialog, click Browse to browse for the device signal tag.
  4. Browse to the SIS Network and double-click the Logic Solver.
    Note

    If the SIS module is assigned to a Logic Solver, the browser starts at the assigned Logic Solver and all DSTs of the correct type are displayed, as well as those of the Undefined type. You may browse up to other Logic Solvers on the same railbus as the assigned Logic Solver. If the SIS module is not assigned, the browser starts at the SIS Network, and you need to browse to the correct Logic Solver.

  5. Select the DST, and then click OK.
    Note

    You can type a DST name in the Object Name box instead of browsing for one. The typed name cannot be the name of an existing control DST. If the tag does not exist in the database, the DST appears in the DeltaV Explorer under Unassigned SIS I/O References.

  6. Click OK in the Properties dialog.
