Programmed communication connections
6.11.1
Programmed communication connections with FB55 IP_CONFIG
Downloading the configuration using FB55 IP_CONFIG
IP_CONFIG allows programcontrolled transfer of the configuration data.
Note
If the CP is in PG STOP mode and the configuration is downloaded using IP_CONFIG, the
CP then changes automatically to RUN.
6.11.2
Programmed communications connections - assigning parameters to the ports
The CP supports the following settings when assigning parameters to the ports in the
parameter block for TCP connections and UDP connections:
● SUB_LOC_PORT parameter
● SUB_REM_PORT parameter
6.11.3
IP access protection with programmed communication connections
In principle, it is possible to set up communications connections using program block
IP_CONFIG (FB55) by programming and at the same time by configuring IP access
protection.
When configuring specified connections (active endpoints) in STEP 7, the IP addresses of
the partners are entered automatically in the IPACL (IP Access Control List).
Communications connections programmed with FB55 are also entered in the ACL as of
firmware version V3.0.
Please note the following point:
Note
The IP addresses of partners with unspecified connections (passive end points) are not
entered in the IPACL. Communication with unspecified nodes is only possible when IP
access protection is enabled if the IP addresses were entered previously in the ACL during
configuration.

The port can be specified as an option when the connection is established actively.
The port can be specified as an option when the connection is established passively.
