Abstract

The PROFIBUS (Process Field Bus) DP is the most popular field bus communication used in the worldwide industry. Many factors contribute for its popularity: protocol simplicity and flexibility in baud rate, cable length and number of equipments by network. This flexibility causes huge acquisition time and reaction time variations for different network setups. This work shows an analog process variable acquisition time measurement in a real network and presents simulation network software that may used to plan different network configurations verifying acquisition time variations.
