ST_IEC870_5_101ClockPollParams

Configuration parameters for the cyclic clock synchronization command. The station sending the clock synchronization commands has its own internal software clock. During station initialization, this clock is synchronized with the local Windows system time (the time shown in the Windows taskbar). During operation, the destination stations are synchronized with the time of the internal software clock via the clock synchronization commands.
