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
S 50 Ω triaxial cable
S 100 Ω Twisted pair cables
S Glass 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.
