Hello xsmart; The repeater introduces a transmission delay in the network propagation, and the Profibus configurator should be made aware of the presence of multiple repeaters in the bus and the total length of the bus in order to recalculate the time delays introduced (Tbit value in network parameters). However you do not have to integrate the repeaters as separate modules in the network configuration. Hope this helps, Daniel Chartier Edit: If you would like to study the issue with more details, I can recommend this Technical Reference for Profibus-DP from Acromag; the last section (starting on page 36) is a discussion on bus timing and introduces the Tbit and Tsdr parameters that the Profibus configurator uses to synchronise the slave exchanges on the bus; https://www.acromag.com/sites/default/files/Acromag_Intro_ProfibusDP_698A.pdf |
