- Abstract
- This paper introduces a mathematical model for analyzing the delay performance of time-critical and time-available data in the Foundation Fieldbus data link layer token-passing service. The mathematical model introduces the concept of virtual token rotation time to account for the dependency of the token rotation times on prioritized data in analyzing their data latency. The validity of the analytical model was verified using a simulation experiment.
