Create a Protective Instrument Loop Sensor Group

This topic describes how to create a Protective Instrument Loop Sensor Group as part of SIL verification. You can also copy or link a Protective Instrument Loop Sensor Group that is associated with another loop.

Note: By default, when you create a Protective Instrument Loop, a Protective Instrument Loop Sensor Group is already created. You can, however, create a maximum of four Protective Instrument Loop Sensor Groups in a loop.

Before You Begin

• Create a Protective Instrument Loop.

Steps

1. Access the Protective Instrument Loop in which you want to add a Protective Instrument Loop Sensor Group.

2. In the workspace, select the Loop Diagram & calculation tab.

   The Loop Diagram & calculation section appears.

   

3. In the diagram, select the Sensor System node, which is represented by the voting architecture.

   The datasheet for the Sensor System appears.

   

4. In the workspace, select Sensor Groups.

   The Sensor Groups section appears, displaying a list of Sensor Groups in the Sensor System.

   

5. In the upper-right corner of the section, select .

   A new Protective Instrument Loop Sensor Group is added to the list of Sensor Groups with a default ID.

6. Select the newly added record.

   A blank datasheet for the Sensor Group appears.

   

7. As needed, enter values in the available fields.

8. In the upper-right corner of the datasheet, select .

   The Protective Instrument Loop Sensor Group is created.

Results

• Along with the Protective Instrument Loop Sensor Group, a Protective Instrument Loop Sensor is also created.
• The newly created Protective Instrument Loop Sensor Group and Protective Instrument Loop Sensor are shown in the diagram.
• The voting architecture in the Protective Instrument Loop Sensor System is updated both in the datasheeet and also in the diagram.
