● Enable telecontrol communication
Enables communication with the master station 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.
SMS
If the CP is intended to use the sending of SMS messages, you need to activate this
separately, refer to the section "Serial Interface" parameter group (Page 62).
Open User Communication
Open User Communication 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.

"Station address": Adoption of the subscriber numbers from STEP 7 V5
The subscriber numbers cannot be edited.
As a default, all CPUs and CP 1243-8 have the subscriber number 0.
The subscriber numbers are only displayed after you have imported the configuration data of
the station from the STEP 7 project.
Adoption of parameters from the STEP 7 V5 project
The displayed parameters are shown alongside the corresponding parameters in STEP 7
V5.
