Industrial ETHERNET Technology
The range of WAGO Switches ensures scalability of your network infrastructure
with outstanding electrical and mechanical characteristics. These rugged devices
are designed for industrial use and are fully compliant with the IEEE 802.3,
802.3u, 802.3ab, 802.3az, 802.3x and 802.1p standards.
They have power supply with a supply voltage range of 9 … 57 V. Characteristics
such as auto-negotiation and auto MDI/MDIX (crossover) on all
10/100/1000BASE-T ports are also realized.
3.3
Switching Technology
Industrial ETHERNET primarily uses switching technology. This technology
allows any network subscriber to send at any time because the subscriber always
has an open peer-to-peer connection to the next switch. The connection is
bidirectional, i.e., the subscriber can send and receive at the same time (full
duplex).
The targeted use of switching technology can increase real-time capability
because the peer-to-peer connection prevents collisions in network
communication.
3.4
Autonegotiation
Autonegotiation allows the switch to detect the transmission rate and operating
mode for each port and the connected subscriber or subscribers, and to set them
automatically. The highest possible mode (transmission speed and operating
mode) is set.
Autonegotiation is available to ETHERNET subscribers connected to the switch
via copper cable.
This make the switch a plug-and-play device.
3.5
Autocrossing
Autocrossing (MDI/MDI-X, “Medium Dependent Interface”) automatically
reconfigures the receive and transmit signals for twisted-pair interfaces as
needed. This allow users to use wired and crossover cables in the same manner
1:1.
