Configuring date/time
Setting time source
The section introduces how to synchronize the controller time to the
SNTP server.
For ControlEdge 900 controller, the synchronization is required in
order to ensure robust operation of the embedded OPC UA server.
1.
From the Home Page, under
Miscellaneous
, click
Configure
Date/Time Options
.
2.
Select
Enable
and enter the IP addresses of SNTP servers in the
Primary Server
and
Secondary Server
fields.
If you select
Enable
here, under
Configure ProtocolsDNP3 Slave
, you
should not select
Enable DNP3 Time Synchronization
in
Application
Layer
tab at the same time.
3.
Adjust the
Poll Interval
to synchronize current controller time to
the SNTP server.
The SNTP message poll interval is Poll Interval power of 2 (2
(Poll
Interval)
) in unit of second.
The maximum poll interval is 17 (approx. 36 hours) and the
minimum is 6 (64 seconds).
It is recommended to set Poll Interval as 16 (approx. 18 hours). To
avoid the communication storm, the controller will pick a random
poll interval time in the range [2
(Poll Interval)
, 2
(Poll I1)
],
not exactly what is configured.
If the NTP server is not available, you can use the function block
(Set_RTC) to configure the controller time. For more information,
