•
P.0415: hours.
•
P.0416: minutes.
•
P.0417: seconds.
You can set the clock manually, but also in the following two ways:
•
Using the Modbus protocol through the communication ports. The BoardPrg3
software, for example, allows the synchronization of the controller clock with the clock
of the PC (it acts on the previous parameters).
•
Using the NTP protocol through the ETHERNET port. It is a standard TCP/IP protocol
that allows to keep aligned the clock of the controller with the clock of an external
server. The IP address of the NTP server must be set by the parameter P.0509; it is
also required to specify the TCP port used by the server using the parameter P.0508
(the default value for this parameter is 123, that is the standard port for all NTP servers
– change it only If required).
The NTP servers provide the date time in the Greenwich meridian format (GMT+0). If
the controller is in a different area, the required GMT value must be specified using
the parameter P.0410. It allows to select both positive and negative values, with a
resolution of 15 minutes. For example, to select GMT+1 (Rome), it must be set to 4
(15 min * 4 = 1 hour).
Note: this value is used while sending data to SI.MO.NE.
server too.
The controller can also manage the daylight save time. This configuration can be done by
means parameter P.0409 that allows the following values:
•
“0 – No”: the automatic management of the daylight save time is disabled. If the NTP
protocol is used, the controller does not add any value to the date/time received by
the server.
•
“1 – Yes”: the automatic management of the daylight save time is disabled. If the NTP
protocol is used, the controller adds the value specified by the parameter P.0408 to
the date/time received by the server.
•
“2 – Automatic (Europe only)”: the automatic management of the daylight save time is
enabled. This configuration can be used only in Europe, because the date/time for the
activation/deactivation of the daylight save time are fixed:
o
The last Sunday of March, 02:00:00.
o
The last Sunday of October, 03:00:00.
At the specified date/time, the controller automatically adds/subtracts the value
specified by the parameter P.0408 to the current date/time: the following updates from
the NTP server will take care of the status (active/inactive) of the daylight save time.
•
“3 – Automatic via calendar”: the automatic management of the daylight save time is
enabled. The date/time for the activation/deactivation of the daylight save time are
configurable by means calendars 15 and 16 (see 11.3.4):
o
Use calendar 15 to specify date/time for the activation of the daylight save
time.
o
Use calendar 15 to specify date/time for the deactivation of the daylight save
time.
Note: when parameter P.0409
is set to “3”, calendars 15 and 16 cannot be used
for other purposes.
At the specified date/time, the controller automatically adds/subtracts the value
specified by the parameter P.0408 to the current date/time: the following updates from
the NTP server will take care of the status (active/inactive) of the daylight save time.
