Benefits
•
The ideal solution for constructing isochronous real-time (IRT)
Industrial Ethernet segments especially in line, star and ring
topologies with copper and fiber-optic cabling (glass FOC,
PCF FOC, POF FOC)
•
Reliable data communication thanks to rugged, industry-
standard device connection using PROFINET-compatible
connectors (IE FC RJ45 Plug 2x2) that offer additional strain
relief and bending strain relief thanks to latching on the
enclosure
•
High network availability in ring topologies, without reconfigu-
ration times, when using the PROFINET-compliant MRPD
process (

according to IEC 61158)
•
Fast and easy diagnosis with LEDs on the device, through the
integral Web server and through signaling contacts
•
Easy integration in the process diagnosis and system
diagnosis with PROFINET
•
Configuration and diagnostics integrated into STEP 7 provide
significant benefits during the engineering, start-up and
operating phases of a plant
•
Module replacement without the need for a programming
device, using the C-PLUG swap media for backing up the
configuration data

Application
The SCALANCE X-200IRT Industrial Ethernet switches permit
the construction of isochronous real-time (IRT) Industrial Ether-
net line and star topologies. Ring structures can also be de-
signed using the integral redundancy manager (RM). Redun-
dant ring connections are also possible. Thanks to innovative
switching technology, the special requirements of automation
with regard to line topology, isochronous mode for motion control
applications and unlimited IT openness have been satisfied for
the first time within a single technology based on the PROFINET
standard.
The switches with IP30 degree of protection have been de-
signed for use in the control cabinet. The switches with IP65/67
protection are designed for cabinet-free mounting (PROFINET-
compliant push pull connection technology).
Real-time Ethernet
•
Interfacing of the PROFINET IO Devices to the PROFINET IO
Controller through high-performance, optimized data trans-
mission
•
Coexistence of isochronous mode for motion control applica-
tions and IT openness:
Reaction-free transmission of real-time and non-real-time
communication on the same line
Additionally through isochronous real-time (IRT) Ethernet
•
Isochronous real-time communication based on the trans-
mission procedure of the IEEE 802 standard by combining the
switching mechanisms "Cut Through" and "Store and Forward"
•
For drive controls, PROFINET with isochronous real-time is the
best performing system worldwide with regard to its isochron-
ronous and deterministic response.
With a cycle time of 1 ms, for example, axes can be controlled
in isochronous mode whereby 50% of the bandwidth is
available solely for IT communication.

Design
•
The SCALANCE X-200IRT switches in a rugged metal housing
with IP30 and IP65/67 degree of protection are optimized for
mounting on a standard rail and an S7-300 rail. Direct wall
mounting in various positions is also possible. Thanks to the
S7-300 housing dimensions, the devices are suitable for
integration into an automation solution with S7-300 compo-
nents.
•
The switches have a 4-pin terminal block for connecting the
redundant supply voltage (2 x 24 V DC). The variants with
IP65/67 protection have two 5-pin push-pull connectors via
which the supply voltage is fed and forwarded. In addition, the
load voltage circuit is also looped through for the ET200pro
devices further along the line. The devices with IP65/67
protection thus have no redundant voltage feed, but permit
optimal integration into cabinet-free plant concepts with
ET200pro modules.
The status information (power, link status, data traffic, voltage
supply, signaling contact) is indicated by means of a row of
LEDs.
The SCALANCE X-200IRT modules are available with the follow-
ing port types:
