Auto-Wire Control Systems Connected to Pre-Assigned Junction Boxes - Intergraph Smart Instrumentation - Help

This procedure explains how to define and execute an auto- wiring task for a control system that is to be connected to a pre-assigned junction box. Note that prior to defining such a task, you must assign the required control system to specific tag numbers.

• You must pre-assign the required junction boxes and make all the required preparations prior to defining and executing a task. For details, see Pre-Assign Junction Boxes to Device Panels.

• Assign the required control system I/O channels to specific tag numbers. For details, see I/O Assignment.

• Make sure that you have made all the required preparations that are specified in Auto-Wiring.

• For auto-wiring tasks involving a connection to a junction box that has not been pre- assigned, see Auto-Wire Control Systems.

1. Start the Wiring module.

2. On the menu bar, select Actions > Auto-Wiring.

3. In the Auto-Wiring Routing Task window, select the new task and then select Actions > Edit Task .

   The Auto-Wiring Routing Task dialog opens where all the End 1 connection properties except for the Connection type and Overall shield terminal connection have been defined. You can accept the displayed values or modify them as needed.

4. On the Auto-Wiring Routing Task dialog, complete the End 1 connection definition as follows:

   1. Select the required connection type from Connection type list.

   2. If required, select the appropriate overall shield terminal connection.

   3. In the End 2 connection group box, select the Control system check box.

   Selecting the Control system check box disables all the options in the End 2 connection group box (except for Connection type) so that Smart Instrumentation can search for an available DCS or PLC panel with a matching signal.

5. From the Connection type list, select the required End 2 connection type.

6. In the Cross wiring group box, select an appropriate cross wiring option to connect the control system to the junction box:

   • Single cross wires — Connects the control system using a single wire created by Smart Instrumentation automatically during the auto-wiring process.

   • Cables created from reference — Connects the control system using a cable that Smart Instrumentation creates by duplicating the reference cable that you select from the Reference cable list in the Cable group box. The software checks whether such a cable exists in the Domain Explorer and if so, whether this cable is connected to the panel selected in the End 1 connection group box. If this cable has unconnected cable sets, the software connects them and then creates additional cables so that all the terminals are connected. Note that in this case, the software connects all the cable sets whether they are required or not. Therefore, for this option to work properly, you must create appropriate reference cables and connection types before starting auto- wiring.

   • One cable per tag — Connects the control system using a separate cable for each tag number. The software creates each cable by duplicating the reference cable that you select from the Reference cable list in the Cable group box. Smart Instrumentation creates the required number of cables according to the number of tag signals it detects. The software names each cable according to the signal name. You can add a prefix and a suffix to the cable name by typing the required string in the Cable name prefix and Cable name suffix fields.

7. Use the options in the Cable group box to define the cable for connecting the pre- assigned junction box to the control system (not available if you selected the Single cross wires option):

   1. From the Reference cable list, select an appropriate reference cable that Smart Instrumentation uses as a source for the creation of a cable that will connect the two panels. The software duplicates the new cable in the Domain Explorer.

   2. In the Cable name data field, the software suggests a cable name composed of the End 1 and End 2 panel names. Accept this name or type a name of your choice for the cable that Smart Instrumentation will create to connect the two panels. Any additional cables that the software creates have identical names with a numeric suffix that is incremented by one for each new cable; for example XYZ.1, XYZ.2, and so forth.

   3. Select OK to complete the task definition and return to the Auto-Wiring Routing Task window.

8. Select .

• After notifying you that the task has been executed successfully, the task status changes to Done. For details, see Auto-Wiring Task Statuses.

• You can open the Connection window for the selected junction box to display the adjacent connection to make sure that the auto-wiring task has been executed correctly.
