5 Configuring Communication Connections
This chapter explains the following:
 The general aspects of configuring communication connections
 How to configure ISO transport, ISO-on-TCP, UDP and TCP connections
 How to use the connection configuration functions to specify communication
partners that exchange data via UDP
You will find a description of the connection-specific properties dialogs in the
following sections:
 ISO transport connections see Section 5.4
 ISO-on-TCP connections see Section 5.5
 TCP connections see Section 5.6
 UDP see Section 5.7
You will find further information in the following sources:
 For the properties of the configurable connection types, refer to Section 1.5
 There are situations in which communication connections are not set up over
the configuration interface of STEP 7 but program-controlled by certain
applications; see also Chapter 6.
 For the properties of the configurable connection type E-mail, refer to /5/.
 You will find information on the numbers of connections and amounts of data in
Section 4.1.
 For information on configuring connections, refer to the online help of STEP 7
