The ipNTP Standalone Timeserver can transmit DCF77 / GPS time information
onto computers, controllers or other dynamically critical devices / applications
ove t client first determines the average transmission time for
the data exch time server. After that the client fetches the current
time and patches this value around the transmission time. The time on the client
deviates then only a few milliseconds from the timeserver.
All components in the TCP / IP network could be synchronized over the SNTP
protocol with the time signal transmitter Mainflingen near Frankfurt at the Main
(DCF77), or through the global satellite navigation system (GPS).
Time-precise solutions are needed in task executions, schedulers, personnel
information systems, time recordings and error logging. Through the commitment
TCP / IP is the platform independen
guaranteed.
