Due to the data point configuration in STEP 7, programming program blocks in order to
transfer the process data is unnecessary. The individual data points are processed one-
to-one in the control system.
●
IP configuration - IPv4 and IPv6
– IPv4 / IPv6
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.
– Address assignment
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.
●
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).
●
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
●
Analog values can be preprocessed on the CP according to various methods.
