Ethernet Interface; Cp Identification; Time-Of-Day Synchronization - Siemens CP 1243-1 Operating Instructions Manual

Configuration

4.6 Ethernet interface

● 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.
