Assigning Addresses For The First Time (Applies To Latest Cps) - Siemens NCM S7 Manual

Installing and Starting the Ethernet CP with STEP 7
2.3 Assigning Addresses for the First Time (Applies to
Latest CPs)
Meaning of the Address Assignment – MAC Address and IP Address
The CP ships with a factory-set MAC address. Without further configuration, the
device can only be accessed over the Ethernet port using this MAC address.
In its original state, you can already use the following functions via the CP using
the ISO protocol and the factory-set MAC address:
S Download the defined configuration to the CP or CPU
S Run diagnostics on the CP or CPU
Before you can download defined configuration data to the device using an IP
address, you must first assign an IP address to the CP.
Assigning the Address – Options and Recommendations
There are three ways of assigning this address in STEP 7:
S Addressing by selecting the target system in the SIMATIC Manager
This option allows you to assign the address without having to set up a STEP 7
project. This is useful, for example, if you want to download defined
configuration data you created offline to the S7 station.
This is described in Section 2.3.1.
S Addressing using the properties dialog in HW Config or NetPro
This option assumes that the CP was networked in STEP 7. The advantage of
this method is that the IP parameters set during configuration in STEP 7 /
NetPro can be used.
In the "Addressing" tab, you assign the previously configured IP address and IP
parameters to the CP.
This is necessary before the configuration data can be downloaded to the CP
over Ethernet.
This is described in Section 2.3.2.
S Downloading configuration data using the ISO protocol
Another option is to download configuration data with a defined IP address
using the ISO protocol (see above).
