DeltaV SIS Simulate is a complete simulation environment you can use to design and test an SLS 1508 safety instrumented system. Most aspects of an SIS simulation system are identical in look and feel to a physical system. This includes configuration (including graphics configuration), diagnostics, and operating (if you have the OPC license and have configured a process simulation with a third-party application). The ability to simulate operation makes SIS Simulate useful for operator training.
You can configure a simulated SIS system only on workstations with the appropriate simulation licenses. There are licenses available that allow different levels of use. You cannot commission or run simulated logic solvers in an online system.
Because DeltaV SIS Simulate is an add-on to DeltaV Simulate, this document explains only the differences and enhancements seen when using DeltaV SIS Simulate.
DeltaV SIS Simulate does not affect the operation of DeltaV Simulate. DeltaV SIS Simulate adds the ability to simulate safety instrumented system configuration and operation to the DeltaV Simulate environment.
DeltaV SIS Simulate features include the ability to configure:
The ProfessionalPLUS workstation as a simulated controller with as many as 32 simulated logic solver cards.
Configure Application Stations as additional simulated controllers, each with 32 simulated logic solver cards.
Communication between simulated logic solver cards in the same workstation using secure parameter references.
Communication between simulated logic solvers in different workstation using global secure parameter references (simulated SISNet Repeaters)
Writing simulated process inputs to SIS modules.
Reading process outputs from SIS modules.
OPC (OLE for process control) to write values to SIS inputs.
The general steps to use DeltaV SIS Simulate are:
Configure a complete simulated safety instrumented system or import a runtime SIS configuration into the simulation system.
Configure operator graphics.
Perform operator training.
Perform a functional test on the simulation system.
Record the CRC checksums.
Export the configuration from the simulation system.
Import the configuration to the runtime system.
Verify that the CRC checksums have not changed.
Copy the operator graphics from the simulation system to the real system. You do not need to make any changes to the graphics.
Perform a functional test on the physical system.
Begin operating.
