Ethernet Interface; Ipv6; Time-Of-Day Synchronization - Siemens ET 200SP Operating Instructions Manual

7. Optional: Create the program blocks for the Open User Communication.
8. Save and compile the project.
Here you will find information on individual parameter groups in the following sections. You
will find information on parameters not described in this manual in the information system of
STEP 7.
Details on the parameters of the telecontrol communication of the CP 1542SP-1 IRC can be
found in the section Telecontrol communication (CP 1542SP-1 IRC) (Page 45).
Details on the parameters of the security functions can be found in the section Security
configuration(CP 1543SP-1) (Page 86).
Loading and saving the configuration data
When you load the station, the project data of the station including the configuration data of
the CP is stored on the CPU. You will find information on loading the station in the STEP 7
information system.

4.3.1

IPv6

Configuring the Ethernet addresses
You will find information on configuration in the information system of STEP 7.
Note
Communication via IPv6
If you want to use IPv6 addresses and connect the CP to the Internet, make sure that the
router connected to the Internet and the providers of the Internet services used (e.g. e-mail)
also support IPv6 addresses.
4.3.2

Time-of-day synchronization

Procedure for time-of-day synchronization
You will find the parameter group for time-of-day synchronization under the Ethernet
interface.
If the Security functions are enabled, the parameter group is displayed below "Security".
Note
Recommendation for setting the time
Synchronization with a external clock at intervals of approximately 10 seconds is
recommended. This achieves as small a deviation as possible between the internal time and
the absolute time.
