2.9. Time handling

There are two different time sources available for accurate time synchronization,

GPS and DCF77. SNTP method is used to provide resource to IP network clients.

DCF77 radio receivers that are connected directly to PC receive radio timing signals

and synchronize Windows platform or MicroSCADA Pro directly.

The most precise time handling method of MicroSCADA Pro system is to use IEC

61850 OPC Server, which can act as an SNTP client and server. For more details,

refer to IEC 61850 Configuration Manual.

If IEC 61850 OPC Server is not used, it is possible to use a client program and GPS

clock, which synchronize the PC clock. There are many server/client utilities which

can be used. Tardis2000 and Yats32 Synchronization applications and Trimble Ace

III clocks have been used in customer projects.

Meinberg’s board PCI511, as shown in Fig. 2.9.-1, has been designed for the

reception of the DCF77 signal, to transfer the time information to a computer with

PCI (PCI-X) bus interface and the translation of the received codes into a serial

telegram. This solution can synchronize MicroSCADA time.
