Organization: ISA
Publication Date: 2 October 2009
Status: inactive
Page Count: 22
scope:

This technical report:

• provides guidance on implementing Safety Fieldbus protocols and devices in safety instrumented systems in the process industries

• recommends additional considerations and practices for the implementation of Safety Fieldbus that are not currently included in ANSI/ISA-84.00.01-2004.

This technical report addresses Safety Fieldbus design and management. It does not provide detailed implementation guidance, which would be different for each Fieldbus technology.

This technical report is limited to the application of Safety Fieldbus to communicate between the safety logic solver (i.e., compliant with ANSI/ISA-84.00.01-2004) and multiple field devices. It does not address implementation of the logic within the Fieldbus segment.
