Start-Up, Tests, and Diagnostics S5-95U, SINEC L2
3.3.2 Prerequisites for Starting Up the S5-95U as a SINEC L2 Station
We assume that the S5-95U is to be connected as a station to an already existing SINEC L2
local area network.
Minimum hardware requirement:
• One S5-95U programmable controller
• One EPROM/EEPROM memory submodule or a back-up battery
• One bus connector or one bus terminal
• One programmer with monitor
Figure 3-5 shows the location of the connectors on the S5-95U.

Parameter Assignments Required in DB1:
• You have set the basic parameters in DB1 (see section 1.4).
• You have set the parameters for the desired data transmission type(s).
Section 1.5 provides information for the selection of the data transmission types.
The specific chapters provide information for assigning parameters for each specific data
transmission type (Standard Connection: chapter 4; PLC to PLC: chapter 6; Cyclic I/O:
chapter 7; layer 2 accesses: chapter 8).
