Automatic cross wiring enables you to instruct Smart Instrumentation to automatically find matching signals for you and cross-wire the relevant terminals in a single operation. Two signals match if:
-
The signals are between two terminal strips belonging to the same panel.
-
Both signals are on the same signal level.
-
The first signal comes to the first terminal from a device panel (the signal sequence is less than 50) and the second signal comes from a control system (the signal sequence is greater than 50.)
You can set the default definitions for matching signals by using the Preferences dialog.
You can set the default definitions for matching signals by using the Preferences dialog. For details, see Set Cross Wiring Preferences.
-
Press F7 open the Domain Explorer and select one or more terminal strips for potential cross wiring. You can also select a panel or several panels if required.
-
Right-click the selected item and on the shortcut menu, select Actions > Cross Wiring.
-
In the Cross Wiring window, select the required terminal strip from the Primary terminal strip list.
To add terminal strips that do not appear on the list, select 
beside the Primary terminal strip list arrow, select the required terminal strips in the Domain Explorer, then select OK to add them to the Primary terminal strip list.
-
Under Primary auto cross- wiring side, select Left or Right to select the appropriate side of the primary terminal strip that you want to connect.
-
From the Secondary terminal strip list, select the required terminal strip that you want to cross wire.
To cross wire two terminal strips belonging to different panels where you did not
select one of the panels in Domain Explorer, select beside the Secondary terminal strip list arrow, select the required terminal strip in the Domain Explorer and select OK to add it to the Secondary terminal strip list. Then, select that terminal strip from the Secondary terminal strip list for cross wiring.
-
Under Secondary connection side, select Left or Right to select the appropriate side of the secondary terminal strip that you want to connect.
This option is not available if the current secondary terminal strip is a terminal
strip with channels (belonging to a DCS or PLC panel). In this case, you can connect
the left side only.
-
From the Cross-wiring cable list, select one of the following to define a cross-wiring cable:
-
Select CROSS WIRE to cross wire the terminals with wires that the software creates during the cross-wiring process.
-
Select the required cross- wiring cable. If the cross wiring cable that you need is not on this list, select
beside the list arrow to open the Domain Explorer. Select a cable and select OK to add it to the list. Note that you can also create a new cross wiring cable if
the one you need does not exist in the Domain Explorer.
-
-
Select the Prompt for cross operation message check box to be prompted by Smart Instrumentation to confirm the cross wiring. If you do not select this check box, cross wiring of the selected terminals proceeds without messages and Smart Instrumentation propagates all the existing signals.
-
Select Actions > Auto
.
Smart Instrumentation finds and selects the matching signals and the terminals that it can cross- wire automatically. The Secondary Terminal Strip pane does not appear in the Cross Wiring window.
-
Select
to cross wire the selected terminals. Smart Instrumentation replaces the selection with a solid black line indicating that the cross wiring has
been done.
OR
Select
to discard the selection made by the software and return to manual mode.
-
After the software cross wired the terminals, select
to return to manual mode.
-
For an example and information about the conventions used to represent various items and connections in the Cross Wiring window, select the Help icon on the main toolbar and then select the required link at the bottom of the help page.
-
In the Primary Terminal Strip pane, select the required cross-wired terminal, and then select
to open the Point-to-Point Wiring Diagram.
-
Select
to open the Terminal Connection window. You can also double click 
to get the same result.
-
Select
to remove the cross wiring between two terminals after selecting the cross- wired
terminals (shown connected by a solid black line).
-
Select
to generate a report that shows all the wiring connections of the primary strip on
both sides.
