MICROSENS
Fast Ethernet switch
for industrial ring application
General
Ethernet has been used in the controlling level of industrial applications for many years.
Ethernet is continuing to beat the field bus technologies used to date in coupling equipment
controls, sensors and actors. Process error-tolerant network components are absolutely essential
because the network availability has a direct effect on production.
It is precisely to prevent this that MICROSENS has developed a mechanism for which a patent is
pending that enables the Ethernet network to be reconfigured within milliseconds if an error
occurs.
The switches can be configured and monitored either by SNMP or a PC-based management tool
(Device Manager). In addition to the Device Manager all statuses are displayed web based using
an integrated HTTP server.
In addition to the two 100Base-FX fiber connections for chain linking several industrial switches,
the MICROSENS industrial switches also offer four 10/100Base-TX connections for linking such
Ethernet terminals as machine controls, network uplinks, consoles and other network
participants.
For particularly demanding uses, the industrial switches are designed in a suitably robust
construction with an integrated clamping device for direct assembly on 35 mm DIN rails. The
devices meet the requirements for IP protection class 20 and are also designed for a larger
temperature range.
The power supply of the devices is done by an external, central power supply unit. With the
second power input the device can be supplied with redundant power. All electrical ports are
either galvanic isolated or equipped with an effective over voltage protection.

Mounting
The switch is housed in a solid metal box with an integrated fixture for the installation on
standard 35 mm DIN EN 50 022 rails.
The fixation of the MICROSENS switch on the rail is done with a locking pin that can be opened
from the bottom side. If multiple devices are mounted in line, a minimum space of 20 mm should
be kept between the devices, to ensure a sufficient heat dissipation.

Switch Features
The integrated switch has a store-and-forward architecture and can transmit all packets non-
blocking between the five ports at full wire speed. For data buffering the switch incorporates
1MB of memory.
Up to 4096 different MAC addresses can be stored simultaneously in the internal switch address
tables. An automatic aging mechanism updates the tables max. 10 min. after the last reception
of data.
Twisted Pair Connections
The integrated auto-crossing function of all Twisted-Pair ports makes the use of crossed patch
cables unnecessary. The switch automatically detects the pinout of the connected cable and
adapts the port accordingly. For all connections standard 1:1 Twisted Pair cables can be used.
The Autonegotiation mechanism detects automatically the speed and transmission mode (full or
half duplex) between connected ports. A manual configuration is not required.
Power supply
The power supply is done by an external power supply with an output voltage of 24 V DC. This
power supply is not included at delivery, but can be ordered separately (MS700420). The
connection is done by the pluggable screw terminals on the top of the device. The connection of
a redundant power supply can be done by the second screw terminal.

Management
The integrated http server offers to show status information by using a standard internet
browser. A special configuration is not necessary. Additional to the web based management the
switch offers a MIB to be used in all standardized Network Management Systems (NMS)
supporting SNMPv1 protocol.
With the PC based management tool Device Manager it is possible to configure all ports of the
switch manually. Please refer to the online manual for the Device manager on the disk.
With this tool it is also possible to do the initial TCP/IP setting (IP address, Gateway etc.). This
configuration can be changed afterwards using the TCP/IP protocol.
Attention: The description for the initial settings can be found in the online manual!
The management information are available inside of the network (inband management). A
special connection is not necessary. Due to this all four twisted pair ports are available to
connect other devices.
With the deactivation of the autonegotiation function of the twisted pair ports the
configuration of the speed to 10 or 100 Mbit/s and full or half duplex mode is done manually.

Ring Function
The two fiber ports of the device can be used to build up a ring structure.
Ring structures are commonly used in industrial and telecommunication environments
as they give redundant protection against failures at minimum cabling expense.
In normal operation the ring connection is logically interrupted by monitoring device
(switch configured for Ring Master mode). In case of failure (broken connection or
switch damage) the logically interrupted connection is activated by Ring Master.
A big advantage of this solution is, that no additional central device is necessary for the
redundancy feature. Even if the ring master itself fails, the interruption of the ring stays
at this location.

Data transmission in failure status
Ring Mechanism
The from MICROSENS patented protection mechanism supports the fast reconfiguration
of the data transmission in case of failure of one fiber segment. This function is a fixed
feature of the industrial switch. During this operation one switch is having the manager
function, all other switches are normal ring switches.
Each switch is monitoring the status of the connected fiber segment. In case of failure
the connected switch forwards this information to the ring manager. The ring manager
terminates the interruption of the ring immediately. The data is transmitted in all
directions then. This fast signaling a fast failure detection within a few milliseconds
(depending on the ring size).

Ring Configuration
The configuration of the operating mode for the ring application is done with the
network management.
At the menu point Hardware Setting it is possible to select the two modes master or
slave. The switch which is configured in master mode is doing the ring manager
functions to avoid the multiplication of the data.
If one connection or one device fails this information is forwarded to the ring manager
(master) by a special protocol. The ring manager keeps the operation of the complete
segment up.
Advantage of this solution is that the ring manager itself has not to be redundant,
because if the manager fails the data can not be multiplied. The segments stays under
operation.
To avoid that the signaling in case of failure has no affect on other rings, it is possible to
define different rings with numbers from 0 to 255 by the network management.
All switches with ring functionality are having the management features included and
are offering the detection and signaling of any failure.
With this concept a limitation in regards to the maximum ring length is not given.

Transmission Speed
The twisted pair ports of the switch are adapting automatically to the highest possible
speed using the autonegotiation protocol. The LED displays are showing the selected
speed. If necessary this configuration can be also done by the network management.

The transmission in full duplex mode is indicated by the related LED (on). If the
connection is working in half duplex mode, this LED indicates collisions for the
connected segment (flashing).
The transmission mode of the fiber uplinks are selected by the network management.
Important is that distances longer than 412 m can be realized only in full duplex mode.
The duplex settings are independent from the mode of the ring feature.
Safety Notes
WARNING: Infrared radiation as used for data transmission within the fiber optic, although
invisible to the human eye, can nevertheless cause damage.
To avoid damage to the eyes:
• never look straight into the output of fiber optic components – danger of blinding!
• cover all unused optical connections with caps.
• commission the transmission link only after completing all connections.
The active laser components used with this product comply with the provisions of Laser Class 1.
DANGER: Conductive components of power and telecommunications networks can carry
dangerously high voltage.
To avoid electric shock:
• Do not carry out installation or maintenance work during lightning storms.
• All electric installations must be carried out in accordance with local regulations.
