Access a Protective Instrument Loop Logic Solver

Before You Begin

• Create a Protective Instrument Loop.

Steps

1. Access the Protective Instrument Loop that is linked to the Protective Instrument Loop Logic Solver that you want to access.

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

   The Loop Diagram & calculation section appears.

   

3. In the diagram, select the Logic Solver node.

   The datasheet for the Logic Solver appears.

   

4. If needed, modify values in the available fields.

   Note: To select a logic solver device from Exida's Safety Equipment Reliability Handbook (SERH):

   1. In the upper-right corner of the Logic Solver Details section, select Set Logic Solver Device.

      The Select a Logic Solver window appears, displaying a list of logic solvers from Exida's Safety Equipment Reliability Handbook (SERH).

   2. Select the logic solver that you want to apply for the Protective Instrument Loop Logic Solver, and then select OK.

      The fields in the Logic Solver datasheet are updated with the values for the selected logic solver device.

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

   The changes made to the Protective Instrument Loop Logic Solver are saved.

Results

• The changes you have made may alter the calculated results for the SIL analysis. The GE Digital APM system calculates the results again.
