There are multiple ways to synchronize the time on the SCADAPack X70.
DNP3 time synchronization over serial and WAN connections
A SCADAPack x70 device operating as a DNP3 Outstation supports the non-LAN time synchronization procedure using DNP3 DELAY_MEASURE and time WRITE requests. Use this procedure for serial and IP wide area networks (WAN) to provide time synchronization, when the DNP3 protocol is used as the time source.
DNP3 time synchronization over Ethernet LAN connections
A SCADAPack x70 device operating as a DNP3 Outstation also supports the LAN time synchronization procedure using DNP3 RECORD_CURRENT_TIME and time WRITE requests. Use this procedure for Ethernet local area network (LAN) time synchronization, when the DNP3 protocol is used as the time source.
Do not use this procedure for serial or IP wide area network WAN connections (such as Ethernet radio, cellular IP, multi-path networks, etc.)
DNP3 time synchronization with multiple DNP3 Controlling Stations
If a DNP3 Outstation has multiple DNP3 Controlling Stations, it is strongly recommended to allow time synchronization from only one specific Controlling Station. This includes time synchronization from other protocols such as IEC 60870-5-104, Modbus via Logic, etc.
Alternatively, use NTP to synchronize time on the SCADAPack x70 device. An IP connection to a local or remote NTP clock source is required.
Application Tip:
Geo SCADA Expert provides a set of configuration options for managing time synchronization. Set Clock Method and other configuration options can be set in the DNP3 Outstation object.
Refer to SCADAPack SCADA Protocols Technical Reference > DNP3 Protocol Reference Information > DNP3 Outstation Operation > Time Synchronization
For optimal time synchronization when using the DNP3 protocol, it is recommended to leverage the time synchronization capabilities provided within the protocol itself. This is usually configured within the SCADA system, such as Geo SCADA, rather than directly in the RTU. SCADA systems that support these functions can facilitate time synchronization over DNP3.
Refer to FAQ How to time synchronize Scadapack RTU from Clear Scada over DNP3 ?
If you prefer to use NTP, you will need to use RemoteConnect 3.0.3 and above. Detailed instructions on setting up NTP can be found in the "Configuring SCADAPack x70 Device Operation" section of the SCADAPack x70 Configuration documentation.
***the NTP service is available on SCADAPack 47x and 47xi models.
