Information required for telecontrol communication
The following information is required for the STEP 7 configuration of the CP:
● Address of the telecontrol server
– IP address
or
– Name of the telecontrol server that can be resolved by DNS
– IPT listener port (55097)
IPT listener port of the telecontrol server. Default setting: 55097
If only connections with TCSB are used (no direct communication), a dynamic IP address
can be assigned to the CP by the Internet service provider.
For addressing a redundant TCSB system, refer to the section Partner stations >
Telecontrol server (Page 70).
● DNS server address(es)
You require the DNS server address if you address the telecontrol server using a name
that can be resolved by DNS and the DNS is not operated by the network provider. You
configure DNS in the parameter group "DNS configuration":
– If you do not specify an address, the DNS server address is obtained automatically
from the network provider (recommended procedure).
– If you want to use a different DNS server, enter its IP address. In this case, DNS
servers of the network provider are not taken into account.

The following parameters from the STEP 7 configuration of the CP are also required for the
configuration of the telecontrol server:
● Address and port of the telecontrol server
● Project number
● Station number
