Create a Protective Instrument Loop Sensor

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

Note: By default, when you create a Protective Instrument Loop or a Protective Instrument Loop Sensor Group, a Protective Instrument Loop Sensor is already created. You can, however, create as many Protective Instrument Loop Sensors as required.

Steps

Access the Protective Instrument Loop Sensor Group in which you want to create a Protective Instrument Loop Sensor.
In the workspace, select the Sensors tab.

The Sensors section appears, displaying a list of Sensors in the Sensor Group.
In the upper-right corner of the section, select .

A Protective Instrument Loop Sensor is created and added to the list of Sensors. If the Diverse field in the Sensor Group is cleared, the sensor will contain the same values as those in the default record.
For the newly added record, in the ID column, select the link.

A blank datasheet for the Sensor appears.
As needed, enter values in the available fields.
In the upper-right corner of the datasheet, select .

The Protective Instrument Loop Sensor is created.

Results

The voting architecture in the Protective Instrument Loop Sensor Group record is updated both in the datasheet and also in the diagram.
If the Diverse field in the Sensor Group is cleared, the modifications to values in the sensor are reflected in other Sensors within the Sensor Group.
The GE Digital APM system calculates the results again.
