Siemens SIMATIC NET PROFIBUS manual FastConnect Bus Connector, FastConnect System

Passive Components for RS-485 Networks

4.2FastConnect Bus Connector

Uses

Using the bus connector for SIMATIC NET PROFIBUS:

SNodes with an electrical 9-pin sub-D interface complying with EN 50170 can be connected directly to the SIMATIC NET PROFIBUS cables

SElectrical segments or individual nodes can be connected to the optical link module (OLM, OBT).

SNodes or programming devices can be connected to a repeater.

Note

The integrated bus terminators and the mechanical specifications of the SIMATIC NET bus connectors are tailored to the SIMATIC NET PROFIBUS cables (cable type A of the PROFIBUS standard EN 50170-1-2). Fitting bus connectors to cables with different electrical or mechanical properties can cause problems during operation!

4.2.1The FastConnect System

Uses

PROFIBUS FastConnect is a system for fast simple assembly of PROFIBUS copper cables.

Design

The system consists of three components:

SFastConnect LAN cables for fast installation

SFastConnect stripping tool

SFastConnect bus connectors for PROFIBUS (with insulation displacement system)

Note

All PROFIBUS FastConnect LAN cables can also be fitted into the normal bus connectors with screw terminals.
