Configuring UDP connection properties

5.7.1

Specifying UDP addresses

Address parameters and connection types
With UDP, the communication partners are addressed by the local and remote endpoints as
follows:
● Local addresses:
● Remote addresses:
Depending on the required connection type, the remote address parameters are either
specified or left open during configuration.
● Specified UDP connection
● Unspecified UDP connection
Configuring addresses
STEP 7 displays proposed values for the relevant local and remote address information. If
necessary, you can set the ports individually.

Note
The term "connection" is also used here for UDP.
The reason:
During configuration (just as in TCP), the communications partners are assigned to each
other and therefore logically "connected". In actual fact, with UDP there is no explicit
connection establishment between communication partners.
You specified a destination station when you created the connection.
Configuring broadcast or multicast provides you with a further option (see Section UDP
with broadcast and multicast (Page 107)).
You entered "unspecified" for the connection partner when you created the connection.
