Overview of Communications Capabilities
The S5-115F offers communications capabilities using the SINEC L1 local area network and a
programmer. All the communications capabilities of the SIMATIC family are available by inter-
posing a programmable controller of the U range. The CP 523 communications processor is still
available for use direct in the S5-115F.

SINEC L1 Local Area Network
SINEC L1 is a communications system that networks SIMATIC S5 programmable controllers. It ope-
rates on the Master-Slave principle. You can connect one master and up to 30 slaves to the
SINEC L1 LAN.
Each node, master or slave, needs a BT 777 bus terminal (transceiver) for signal level conversion.
Connect the terminal to the programmer port of the slaves or to the SINEC L1 interface of the
CP 530. The transceiver is powered by a separate 5 V power supply unit.
Note
Contrary to the information in the SINEC L1 LAN Manual, the BT 777 transceiver must
remain as supplied, i.e.
•
You must not remove jumper Q8
You must not insert the jumper between pins 6 and 7.
•
Data is transmitted via a 4-wire shielded cable, which connects the individual transceivers to each
other.
