Emerson Collaborates with exida to Reduce Complexity and Time Required for Safety System Setup
31 October 2017
Emerson and exida announce the release of the DeltaV™ safety instrumented system (SIS) configurator, an exida exSILentia® tool that automatically generates DeltaV SIS configurations. By pairing built-in DeltaV functionality with exida’s comprehensive software tools for functional safety, users can develop safety logic configurations much faster and in fewer steps. Project teams can not only decrease time and effort of safety system configuration, but also deliver more consistent configurations with fewer errors, requiring less rework.
In traditional SIS configuration, project teams use the safety requirements specification (SRS), along with custom-built cause and effect matrices (CEM) as the basis for system configuration. The CEM data is manually interpreted and coded into the safety logic to configure the system. This configuration model requires multiple stages of data entry, taking too much time and presenting opportunities for human error. The new DeltaV SIS configurator leverages data structures created during the conceptual safety instrumented function (SIF) design, safety instrumented level (SIL) verification, and the SRS to automatically generate the safety system configuration.
“With the DeltaV SIS Configurator, programming the logic only takes a fraction of the time, so the SIS conceptual design can be finalized before programming begins. This eliminates any rework due to changing requirements and dramatically impacts project schedule,” said Iwan van Beurden, chief technology officer and director of product development at exida.
With automated SIS configuration, there is no need for entering data in multiple tools; everything is entered once into exSILentia, and an automated tool translates the information into the DeltaV safety logic configuration. The SRS data, SIF definition, and the associated SIL verification data are included.
“Using automatic SIS configuration, project teams can deliver accurate safety logic with minimal programming,” said Sergio Diaz, DeltaV SIS product marketing manager, Emerson Automation Solutions. “Less data entry means more consistency between engineers, leading to less validation time and faster startups.”
“By minimizing the need for manually entered data and automating other critical steps, this jointly developed solution addresses some key pain points and should be able to help end users design and implement safer systems more efficiently, maintain these systems, and ensure compliance with pertinent regulations and standards,” says Mark Sen Gupta, research director with ARC Advisory Group.
