● IP configuration - IPv4 and IPv6
– IPv4 / IPv6
– Address assignment
● Time-of-day synchronization
The CP supports various methods of time-of-day synchronization. You will find
information in the section Time-of-day synchronization (Page 42).
For information on the format of the time stamp, refer to the section Datapoint types
(Page 89).
● Storage of events
The CP can store events of different classes chronologically and transfer them
spontaneously or together to the telecontrol server.
● Data transfer is on request or triggered
The telecontrol communication with the communications partner is triggered in two ways:
– After a request by the master or an OPC client connected to TCSB
– Unsolicited, triggered by various selectable criteria

The CP supports IP addresses according to IPv4 and IPv6.
For telecontrol applications in IPv6 networks, an IPv6 address can be used in addition
to an IPv4 address.
The IP address, the subnet mask and the address of a gateway can be set manually
in the configuration.
As an alternative, the IP address can be obtained from a DHCP server or by other
means outside the configuration.
