S5-95F on SINEC L1
SINEC L1 is a local area network (also sometimes called a bus, or channel) for interconnecting
SIMATIC S5 programmable controllers; it functions on the master-slave principle.
More detailed information on SINEC L1 local area networks can be found in the "SINEC L1
Manual". It has been assumed that the reader of this document is familiar with how a SINEC L1
LAN works.
The S5-95F can be used as slave station. The required information is presented in the following
manual sections.
13.1
Options for Connecting the S5-95F to the SINEC L1 LAN
There are two ways to interface an S5-95F to SINEC L1:
•
For a pure point-to-point connection between master and slave, the programmable controllers
are interfaced via a direct cable connection (possible only when the two units are less than
100 m apart). For a point-to-point connection, use a four-wire shielded cable with a cross
section of no less than 0.14 mm
used. If you have any questions, please contact your local Siemens branch office.
•
If there are several nodes on the channel, connect the controllers using BT 777 bus terminals.
A bus terminal serves as level converter.
The hardware configurations for failsafe and nonfailsafe data transfer are identical. A separate power
supply for BT 777s, such as that required for the S5-115F, is unnecessary.
Warning
!
To ensure protection against dangerous touch voltage, all SINEC L1 components must
be operated by electrically separate power supplies.
