Configuration and operation
4.15 STEP 7 configuration of individual parameters
CP 1243-7 LTE
66 Operating Instructions, 01/2015, C79000-G8976-C381-01
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.
Note
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.
In this parameter group, you enable the communication type of the CP.
To minimize the risk of unauthorized access to the station via mobile wireless, 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 telecontrol communication
Enables communication with a Telecontrol server on the CP.
Note:
To enable telecontrol communication, the Security functions must also be enabled.
●
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 on the CP.
Open User Commmunication does not need to be enabled since you then need to create the
relevant program blocks. Unintended access to the CP is therefore not possible.
