Plc-To-Plc Connection Between Active S5-95Us - Siemens SIMATIC S5 Manual

System Description
Selecting the Types of Data Transmission to Suit the Hardware Configuration
Except in a few cases, you will still not be able to make a final decision as to which type of data
transmission to use based solely on the information found in Tables 1-8 and 1-9: if, for example,
the amount of data to be expected is not clear.
Typical partial configurations of a SINEC L2 network are illustrated in Figures 1-8 and 1-9.
These partial configurations correspond to the situations encountered most frequently in the
industry. They are presented here according to the frequency of their occurrences (high to low). In
the chapters dealing with the individual types of data transmission (see chapters 4, 6, 7 and 8),
these typical partial configurations are the basis for the examples for assigning parameters and
programming with the S5-95U.
