Ethernet TCP/IP communication services
The time synchronization service is based on the NTP (Network Time Protocol)
that is used to synchronize the time of a client or a server on Ethernet TCP/IP
from a server or another reference time source (radio, satellite, etc.).
Ethernet TCP/IP communication modules for automation platforms:
v
v
component.
These modules can connect to an NTP server using a client request (unicast),
to update their local time. The module clock is updated periodically (1 to 120
seconds) with an allowable variation of less than 10 ms for standard processors and
less than 5 ms for high performance processors.
If the NTP server cannot be reached, the Ethernet TCP/IP module switches to a
standby NTP server.
(1) Time difference between the physical input and the central NTP server.
(2) With use of an interrupt input module.
The PLC processor clock is updated with a precision of 5 ms for standard processors
and 1 ms for high performance processors. A function block is available for reading
this clock. In each PLC application, events or variables can be time-stamped.
The Ethernet module is configured via a Web page. The time zone can be
configured. A time synchronization service (NTP) diagnostic Web page is also
available.
Information on the time synchronization service (NTP) is also available in the
Transparent Ready
management service (see above).
