Preface
Overview of the SCALANCE X product family
The SCALANCE X-200 product family is part of the SCALANCE X product family. Below,
you will find a brief overview of this product family.
The SCALANCE X family comprises various product lines that complement each other and
that are carefully tuned to specific automation tasks.
SCALANCE X005 and XB000 line, entry level
Unmanaged switch with five twisted-pair ports and optical diagnostics on the device for use
in machine and system islands.
SCALANCE X-100 unmanaged
Switches with redundant power supply and signaling contact for use in applications in the
immediate vicinity of machinery.
A variety of device variants with different numbers and designs of electrical and optical ports.
SCALANCE X-200 and XF-200 managed
The devices of the SCALANCE X-200 product line can be used universally – in machine-
level applications as well as in networked plant sections, in electrical or electrical/optical
linear, ring or star structures and with single mode up to 26 km.
Devices with a high degree of protection (IP65/67) can be installed outside the control
cabinet.
Configuration and remote diagnostics functions are integrated in the STEP 7 engineering
tool. This increases plant availability and has advantages during the engineering,
commissioning and operational phases. The devices of the SCALANCE X-200 line also have
standard remote diagnostics functions (SNMP, Web server).
The only difference between the devices of the SCALANCE XF-200 product line and the
SCALANCE X-200 product is the flatter construction.
SCALANCE X-200IRT and XF204IRT managed
In subsystem networks with hard real-time requirements (real time and isochronous real
time), the SCALANCE X-200IRT switches can be used. They include the enhanced real-time
controller ERTEC. By using the "cut through" switching mechanism, the switches are ideal to
meet the real-time requirements of PROFINET.
The standard data transmission (TCP/IP) can take place on the same network. Dual network
structures are therefore not necessary.
Network installation, configuration and diagnostics involves the same procedures as for the
other devices of the SCALANCE X-200 product line.
