Configuration and operation
5.2 Configuration in STEP 7
CP 1243-1 PCC
30 Operating Instructions, 02/2015, C79000-G8976-C384-01
Required information for the Plant Cloud Communication
The following information is required for the STEP 7 configuration of the CP:
● Address of the operation center
The URL address of the operation center.
● DNS server address(es)
You require the DNS server address if you address the operation center 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.
