Select a Field Device Terminal Configuration

Although the specified Wiring Rule (in the Wiring Config field) defines the terminal configurations of the Field Device, Users can select a different configurations clicking on the button in the Tag No field and selecting from the list of configurations in the Select a Field Device Terminal Configuration window that is then displayed.

The Graphic tab displays graphical representations of each available configuration. The List tab displays them in a simple list.

To select a configuration and exit the window, either double-click on it, or single click on it and click Select.

Assign Wiring Rules to Tags

1. To select a wiring rule to apply to a tag, click the button in the Wiring Config field of the Create Tag Wiring for window.

   The Wiring Rule Definitions window is then displayed:

   

2. Select the required rule from the list on the left. If required, use the facilities above the list to filter the number of rules displayed.

   A graphical representation of the rule is displayed on the right. Click OK to apply the rule to the field device.

   The window then exits, and the selected rule is displayed in the Wiring Config field of the Create Tag Wiring for window. The Cable Number and Cable Type fields are also completed or updated as appropriate.

   See Instrument Wiring Manager documentation for information on creating and editing wiring rule definitions.

Assign a Junction Box

When selecting a Junction Box when applying Wiring Rules, the following Assign <Tag Number> to... window is displayed, initially listing all junction boxes defined in the current plant area:

3. Select the All Areas option to view equipment in all plant areas.

4. To assign a Junction Box, double-click on the required equipment tag.

   Junction Boxes and other Equipment (other than field devices) can only be created in the Instrument Wiring Manager module.

Notes: In order to select another Tag as the Junction Box (cable end) connection that tag must have previously been created by a Wiring Rule for it to appear in the List of Equipment. For example, to connect a Field Element to a Transmitter, first the Transmitter must be created, then the element must be assigned to the Transmitter (e.g the Transmitter becomes the element's Junction Box).

The instrument Signal Type is shown near the top of this window. This comes from the Instrument's Signal Type field in the Instrument Data window. However any instrument may be assigned to any junction box, regardless of signal type.

The maximum number of cables that may be connected to a junction box may (optionally) be specified in Instrument Wiring Manager. If the application of a wiring rule would result in more than when the maximum number of cables being assigned to it, a message is displayed to inform you of this.
