STEP 7 configuration of individual parameters
Below, you will find information on the configuration of individual functions grouped
according to parameter groups in STEP 7.
Information in STEP 7 and in the manual
If there are discrepancies between the following descriptions and the information in STEP 7 /
Professional V13, the information in this document is valid.
Communication types and SNMP
In this parameter group, you enable the communication type of the CP.
To minimize the risk of unauthorized access to the station via Ethernet, you need to enable
the communications services that the CP will execute individually. You can enable all options
but at least one option should be enabled.
"Communication types" parameter group
● Enable Plant Cloud Communication
Enables communication with the operation center on the CP. Two operation centers can
● Activate online functions
Enables access to the CPU for the online functions via the CP (diagnostics, loading
project data etc.). If the function is enabled, the engineering station can access the CPU
via the CP.
If the option is disabled, you have no access to the CPU via the CP with the online
functions. Online diagnostics of the CPU with a direct connection to the interface of the
CPU however remains possible.
● Enabling S7 communication
Enables the functions of S7 communication with a SIMATIC S7 on the CP.
If you configure S7 connections to the relevant station, and these run via the CP, you will
need to enable this option.
"SNMP" parameter group
● Enable SNMP
Enables communication using SNMP on the CP.
If security functions are enabled, you will find the entry in "Security".
