During your wiring design, situations can arise in which the propagation of a tag signal does not occur automatically. Smart Instrumentation lets you effect signal propagation at terminal strip level by manually entering or changing a signal or its level at any point along the wiring path. You need to propagate tag signals manually when:

  • There is a split in the wiring path.

  • There are terminal strips that emulate barriers.

  • You cross-wire two terminals, one of which already receives a signal.

  • You remove a signal that is stopping tag signal propagation.

  • You add another signal level at an exit point of one of the terminal strips.

  1. Do one of the following:

    • In the Connection window, from the Terminal Strip list, select the terminal strip for which you want to effect signal propagation manually.

    • In the Cross Wiring window, from the Primary terminal strip list, select the terminal strip for which you want to effect signal propagation manually.

  2. Double-click next to the required wired terminal.

  3. On the Terminal Connection dialog, under Signal, select and then select from the list the signal that you want to propagate.

  4. Under Signal Level, select and select from the list, a value for the signal level.

    SHARED Tip You can also select zero to indicate that a signal does not have a signal level setting. This means that all the wires in the current wire group are propagated on the same level.

  5. Under Sequence, select and select from the list a connection sequence.

  6. Select Save to propagate the signal.

  7. To navigate to other terminals for which you need to change propagation settings, do one of the following:

    • Select Next or Previous.

    • Under Terminal number, select a terminal that you require.

  • Repeat the above procedure for each terminal strip that requires manual signal propagation.

  • If you remove a signal at any point of the wiring path, Smart Instrumentation stops the signal propagation at that point. However, if there is an I/O card at the other end of that signal path, the Smart Instrumentation stops the tag signal propagation at the break point and assigns a new connection sequence (100, 99, 98 …) starting from the I/O card.

  • If you replace one signal with another at any point along the wiring path, the software stops the propagation of the old signal at the point where you made the change and propagates a new signal from that point onward to the end of the signal path.
