D.3 Basic application functions
Cyclic data transmission
Cyclic data transmission is used to send measured values to the IEC 60870-5-104 master.
Spontaneous Transmission:
Information objects may be transmitted without a specific request from the IEC 60870-5-104 master.
The data that can be sent spontaneously are:
• Measured values when a deadband overflow takes place.
• Single points in the time the event is produced.
• Double points in the time the event is produced.
•Integrated Totals
Clock synchronization
F650 supports clock synchronization from IEC 60870-5-104 master.
If IRIG-B, PTP-1588 or SNTP is being used for time synchronization, the IEC 60870-5-104 clock synchronization command
does not set the F650 real time clock.
Command transmission
F650 is allowed to accept single commands and double commands.
