ibaPDA time synchronisation


ibaPDA offers the following options for time synchronisation:

  • DCF77
    • Using a time receiver. To synchronise multiple ibaPDA PCs you feed the required binary signal from the receiver to each of the systems (with an accuracy of 3ms)
    • or to a controller and the iba system if you want to synchronise the ibaPDA with the controller.
    • In the latter case the DCF77 signal may also be generated by the controller (e.g. with Simatic TDC, FM458)
      You can find instructions for this setup in the ibaPDA-Request-SD-TDC manual, chapters 4.4 and 5.5.

  • IEC 1131
    • ibaPDA may interpret any acquired signal as an IEC 1131 time signal. For synchronising multiple ibaPDA systems you may feed the same source signal to each of them.
    • For synchronisation with a controller again the signal can be generated by the controller. The instructions to do this can also be found in the manual mentioned above.
  • ibaPDA is able to work (using Ethernet) as a PTP (Precision Time Protocol) server or PTP client. It is possible for an ibaPDA system to sync its own time with a different method and then sync other ibaPDA PCs over PTP.
  • Using ibaClock and a FOB-D board you can set the time with an accuracy better than 150 micro seconds. ibaClock can also work as an NTP server.
  • Using Windows NTP time service for receiving the time from an NTP server. NTPv4 can usually maintain time to within 10 milliseconds (3rd party products required, the Windows NTP service cannot maintain an accuracy better than 1-2 seconds).
