Differences for isochronous and non-isochronous communication:
Isochronous The ping compensation value is determined in the converter.
not isochronous You can influence the accuracy of the ping compensation using the PZD
Time synchronization via Network Time Protocol (NTP)
Through NTP, all computers worldwide can synchronize their time. An inverter configured as
an NTP client synchronizes the time via a PROFINET connection to an NTP server (a time
source).
As NTP server, the following constellations are possible:
● Local NTP server that receives the time via GPS or DCF77 (e.g. SICLOCK).
● Control as NTP server if the plant network is divided into a control level and a field level.
