Time synchronization - ibaClock

Time synchronization for distributed systems

With the time synchronization module ibaClock, several distributed iba systems can be synchronized precisely. ibaClock provides a precise time basis for all connected systems and enables an exact synchronized data acquisition.

At a glance

 ·         High precision time server

Highest precision

The timebase for ibaPDA systems is the clock of the respective ibaPDA computer. In case decentrally acquired data have to be correlated or a measurement has to be done in real time, it is necessary in such distributed systems to synchronize all computers or provide the exact GPS time to a computer.

ibaClock determines a uniform, exact time basis for all connected systems and enables an exact time synchronous recording of the data with a precision of better than 150 ns. The measurement systems are connected to ibaClock using fiber optic cables.

ibaClock can use different time sources:

 ·         GPS time signal

 ·         Timecode IRIG-B

 ·         Ethernet-based PTP (Precision Time Protocol) according to IEEE 1588 standard

For synchronizing the time of non-iba systems, ibaClock supports several time server models:

 ·         Fiber optics for ibaPDA systems

 ·         IEEE 1588 (PTP)

 ·         NTP

 ·         DCF77*

*for future fi rmware versions.

Configuration in ibaPDA or Web Interface

ibaClock can be confi gured using ibaPDA or a web interface. The user can see the quality of the GPS signal and the device status on the LED display of the device or in the web interface and ibaPDA.

Antenna

The device supports a special GPS smart antenna, that can be mounted with a cable length of up to 400 m from the device. The antenna with a suitable cable and an optional mounting bracket can be purchased from iba.

Fields of application

 ·         Correlation of decentrally acquired data

 ·         Linking processes in decentralized structures

 ·         Energy supply (phasor measurement)
