As an integrated control and safety system (ICSS), DeltaV™ and DeltaV SIS™ provides integrated engineering, maintenance and operations environment. All safety-related information is easily accessible through familiar and intuitive applications. The integrated but separate architecture complies with standards for physical separation and independence of safety and control, delivering the benefits of total integration and total separation without the tradeoffs associated with the two extremes.
The DeltaV SIS power supplies, communication channels, hardware and real-time operating systems are physically separate and independent of the basic process control system (BPCS). This maintains the separation required by IEC 61508 and IEC 61511 standards. DeltaV SIS automatically monitors, controls and collects safety-related data.
The operator interface provides a powerful environment for safety operation, with built-in features for easy information access. To more effectively operate your plant, operators have one common operating environment for both the basic process control system (BPCS) and SIS when using the DeltaV control system.
The engineering software allows you to manage all aspects of DeltaV and/or DeltaV SIS configuration, including hardware configuration, control strategies, built-in change management and history. The DeltaV SIS system maintains proper security on safety logic software and makes the management of required safety logic modifications easier.
To manage change and maintain compliance over time, the DeltaV SIS system provides comprehensive version control and audit trail functionality for required engineering modifications. Electronic signatures ensure proper authorization for online changes.
No matter what DCS or PLC you are using as your basic process control system, you can increase your plant's availability using the advanced diagnostics in Emerson's Smart SIS solution. Modbus RTU and Modbus TCP can be used to integrate the DeltaV SIS system and your BPCS. The DeltaV SIS system can connect with your BPCS via OPC or OPC .Net. All operating and event information can be made available to your operator interfaces and history collection software as part of an integrated solution.
