Siemens V 4.0 manual System-wide settings, Host-specific parameters, Application-specific parameters

Overview

transmitted by both sides. The controlling application simply has priority over the passive application. From a performance point of view, the controlling application should be the one which generally (or more frequently) opens the communication.

The definition of the type and number of all connections between the applications is equiv- alent to the definition of the communication structure for the entire system.

Figure 1 on page 44 is a symbolic representation of the hierarchies in the definition of this communication structure. It is not drawn to scale to reflect the scope of the individual sub- descriptions. Depending on the particular network structure, the definition of the connec- tions between the applications can be much larger than the definition of the applications.
