Product manual | Version: 1.0.1 11
Industrial-Eco-Switch
3Overview
The 852-111/000-001 Switch is an industrial, unmanaged ETHERNET switch with
5 x 10/100BASE-TX ports. Its slim design paired with a DIN-rail adapter simplifies instal-
lation in the control cabinet and provides high vibration and shock resistance. Addition-
ally, automatic transmission rate detection (auto-negotiation) and automatic identification
of the transmit and receive lines (Auto MDI-X) allow simple plug-and-play operation, help-
ing save time and money during commissioning.
3.1 Industrial ETHERNET Technology
WAGO’s range of switches ensures the scalability of your ETHERNET network infrastruc-
ture, while providing outstanding electrical and mechanical performance. WAGO's
switches have robust enclosures and are designed for industrial use in compliance with
the IEEE 802.3, 802.3u, 802.3x and 802.1p standards. They have power supply with a
supply voltage range of 12 … 48 VDC. Features such as auto-negotiation and auto-MDI/
MDIX (crossover) on all 10/100 BASE-TX ports are also implemented.
3.2 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 tech-
nology can increase real-time capability because the peer-to-peer connection prevents
collisions in network communication.
3.3 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. Autonegotia-
tion is available to ETHERNET subscribers connected to the switch via copper cable.
This make the switch a plug-and-play device.
3.4 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.
3.5 Functioning of Switches
Switches analyze all incoming data packages and forward them to the port where the cor-
responding destination address is located. Exceptions are the multicast and broadcast
telegrams, which are forwarded to all active ports of the switch.

852-111/000-001Overview
12 Product manual | Version: 1.0.1
Industrial-Eco-Switch
For selective forwarding of the telegrams, each switch contains of an address / port as-
signment table in which the assignments of the destination addresses to a specific port of
the switch are stored. The address / port mapping table is typically generated and main-
tained automatically by the switch through a self-learning process. Incoming data pack-
ages are analyzed, filtered and forwarded directly to the appropriate port by using this as-
signment table based on their destination address. The incoming data package is sent to
all ports, if there is no corresponding entry in the assignment table for a destination ad-
dress. If a destination address answers, the assignment table is complemented with this
destination address as well as the associated port.
3.6 Store-and-forward switching mode
In “Store and Forward” mode, the ETHERNET switch caches the entire data telegram,
checks it for errors (CRC checksum) and if there are no errors, puts it in a queue. Subse-
quently, the data telegram (MAC table) is selectively forwarded to the port that has ac-
cess to the addressed node.
The time delay required by the data telegram to pass the store-and-forward switch de-
pends on the telegram length.
Advantage of “Store and Forward”: The data telegrams are checked for correctness and
validity. This prevents faulty or damaged data telegrams from being distributed via the
network.
3.7 Line Depth in PROFINET
Line depth (cascading) is the number of all switches in a communication path.
The maximum line depth depends on the send cycle.
Note
Observe line depth!
Observe the maximum line depth for switches in Store-and-Forward mode according to
the “Topology Check” section of PI-PROFINET Commissioning Guideline
(PROFINET_Commissioning_8081) (üwww.profibus.com).
3.8 Port Speed & Duplex Mode
After a cable is connected to a specific port, the system uses the auto-negotiation func-
tion to determine the transmission mode of the new twisted pair connection:
If the connected device does not support auto-negotiation or has auto-negotiation dis-
abled, an auto-sensing process is initiated to select the speed and set the duplex mode to
half duplex.
