S7-CPs for Industrial Ethernet Configuring and Commissioning
Release 01/2007
C79000-G8976-C182-07
Note
Read the description of FB55 IP_CONFIG in Section 7.6.
Configuration Limits
A maximum of 64 connections can be specified in FB55 CP_CONFIG. The most
important factor, however, is the maximum number of connections supported by
the CP type you are using (see /2/).
Special Features / Restrictions
Consistency check only with STEP 7
The connection configuration in STEP 7 involves consistency checks that are
not possible or only possible with restrictions when using the programmed
configuration!
Connection configuration required on the partner
When configuring specified connections in STEP 7, you implicitly create the
connection for the partner; with a programmed configuration, this is not
possible! In this case, you must configure suitable connections for the partner.
DHCP / DNS is supported
IP address assignment is also possible using DHCP/DNS even if you choose
programmed configuration.
No connection information when uploading
When you upload the S7 station data in STEP 7, this does not contain the data
of the programmed configuration.
