8.9 Interface in the user program
8.9.1 Programmed communication connections with FB55 IP_CONFIG
Downloading the configuration using FB55
FB55 allows programcontrolled transfer of the configuration data.
Note
If the CP is in PG STOP mode, the configuration is downloaded using FB55; the CP then
changes automatically to RUN.
8.9.2 IP access protection with programmed communication connections
In principle, it is possible to set up communication connections using FB55 by programming
and at the same time by configuring IP access protection. Please note the following point:
NOTICE
When configuring specified connections in STEP 7 / NCM S7, the IP addresses of the
partners are entered automatically in the IPACL (IP Access Control List).
The IP addresses of partners with unspecified connections (passive end points) and of
partners on programmed communication paths are not entered in the IPACL. This means
that communication with unspecified nodes is not possible if IP access protection is
activated.
8.9.3 Programmed communications connections - Assigning parameters to the port
The CP now supports the following settings when assigning parameters to the port in the
parameter block for TCP connections and UDP connections:
● SUB_LOC_PORT parameter
The port can be specified as an option when the connection is established actively.
● SUB_REM_PORT parameter
The port can be specified as an option when the connection is established passively.
