Siemens SIMATIC NET PROFIBUS manual Industrial Ethernet/Fast Ethernet, AS-Interface

PROFIBUS NETWORKS

Industrial Ethernet/Fast Ethernet

A communication network for the LAN and cell area using baseband technology complying with IEEE 802.3 and using the CSMA/CD medium access technique (Carrier Sense Multiple Access/Collision Detection). The network is operated on

S50 Ω triaxial cable

S100 Ω Twisted pair cables

SGlass fiber-optic cable

AS-Interface

The actuator sensor interface (AS-i) is a communication network for automation at the lowest level for connecting binary actuators and sensors to programmable logic controllers via the AS-i bus cable.

PROFIBUS

A communication network for the cell and field area complying with EN 50170-1-2 with the hybrid medium access technique token bus and master slave. Networking is on twisted pair, fiber-optic cable or wireless.

PROFIBUS-PA

PROFIBUS-PA is the PROFIBUS for process automation (PA). It connects the PROFIBUS-DP communication protocol with the IEC 61158-2 transmission technique.
