Communication via Ethernet CPs in S7 Stations

Configuration and Diagnostics

To connect and configure the Ethernet CP, you require the STEP 7 configuration software and the SIMATIC NET NCM S7 for Industrial Ethernet option.

NCM S7 for Industrial Ethernet is installed as a STEP 7 option and is therefore integrated in STEP 7.

NCM S7 for Industrial Ethernet also provides a wide range of diagnostic functions for the various types of communication.

When configuring PROFInet communication, you also use the engineering tool SIMATIC iMap; for detailed information on SIMATIC iMap, refer to the manual Component based Automation – Configuring Plants with SIMATIC iMap /23/.
