Abstract
Installation and wiring work for today’s fieldbus installations in process automation,
FOUNDATION Fieldbus H1 and PROFIBUS PA, currently requires tedious manual and
typically incomplete methods for checkout and validation. New online advanced physical
layer diagnostic systems automate construction and pre-commission test and report
generation, up to the point of loop checkout. Fully automated fieldbus test methodology
realizes better installation quality and time savings.
This paper describes a newly revised, significantly shortened and vastly simplified test
procedure applicable to fieldbus systems. Additional guidelines for troubleshooting that
is described herein will further enhance commissioning and testing work. A case study
compares the new working procedure to existing technologies and procedures and
shows the savings potential, which expresses itself in a reduction in commissioning
time.
