Using fieldbus physical layer diagnostics in maintenance practice

Abstract

An availability of valuable physical layer diagnostic information in maintenance practice is presented in this article. Establishing an effective and efficient maintenance capability for Foundation Fieldbus segments installed at the Tail Gas Treating Unit, IRPC Public Company Limited, Thailand is described as an illustrative case study. Diagnostic-driven maintenance strategy not only reduces fixed and variable maintenance costs but also extends useful asset life by reducing the interval between maintenance events, reducing the cost of failures, and making it easier to plan maintenance and service work. © 2013 ICIC International.
