Design
The SCALANCE XF-204IRT managed Industrial Ethernet switch
is designed for mounting on a standard mounting rail.
With its enclosure in ET 200S format (slim design), the device
is optimally suited for integration in automation solutions in small
control boxes together with the ET200S.
The switch with degree of protection IP30 features:
•
2 x 2-pole terminal block for connecting the redundant supply
voltage (2 x 24 V DC)
•
A row of LEDs to indicate the status information (power, link
status, data traffic, power supply, signaling contact)
•
A 2-pole terminal block for connecting the isolated signaling
contact
•
A SET button for on-site configuration of the signaling contact
The SCALANCE XF204IRT switch is available with the following
port types:
•
10/100BaseTX, RJ45 connection;
RJ45 socket, automatic detection of the data rate (10 or 100
Mbit/s), with Autosensing and Autocrossover functions for
connecting IE FC cables using the IE FC RJ45 Plug 180.

Function
•
Configuration of electrical Industrial Ethernet line, star and
ring topologies
•
Integral redundancy manager for setting up ring topologies
•
Integral standby function for redundant coupling of two rings
•
Extremely short cycle times with highly accurate clock-pulse
rates thanks to integrated real-time functions
•
Bumpless ring redundancy by sending message frames twice
in the ring, by means of PROFINET-compliant MRPD
procedure (

according to IEC 61158)
•
System-wide clock accuracy (deviation less than 1 ms)
•
Uncrossed connecting cables can be used due to
Autocrossover function integrated in the ports
•
Easy diagnostics using signaling contact, SNMP and Web
browser
•
Integration into the diagnostics of a PROFINET IO Controller
by means of real-time communication (RT) according to the
PROFINET standard
•
Fast device replacement in the event of a fault by using the
optional C-PLUG swap medium (not included in scope of
supply)
Network topology and network configuration
The SCALANCE XF204IRT Industrial Ethernet switch with IP30
degree of protection is installed in a control cabinet together with
the stations to be connected. It can be combined electrically in
star, line and ring topologies.
When configuring the network, it is necessary to observe the
following boundary conditions:
•
Length of the TP cable between two SCALANCE XF switches:
- Max. 100 m with IE FC cable and IE FC RJ45 Plug 180
•
IP Address:
The IP address is assigned using the DHCP (Dynamic Host
Configuration Protocol) mechanism. If there is no corre-
sponding server in the network, the IP address can be
assigned using the supplied software tool PST (Primary Setup
Tool) or STEP 7. The device and real-time configuration of the
SCALANCE XF204IRT switch is performed via STEP 7.

Commissioning and diagnosis
PROFINET diagnostic interrupts from SCALANCE XF204IRT can
be displayed with the appropriate SIMATIC Engineering Tools
and processed in the controller with expanded diagnostics
function. The engineering outlay for the PLC and HMI have been
drastically reduced due to the complete integration in the
SIMATIC concept for system error messages.
The SCALANCE XF204IRT Industrial Ethernet switch can also be
integrated into a network management system, e.g. SINEMA
Server, through the standardized Simple Network Management
Protocol (SNMP). In the event of a fault in the device, error mes-
sages (SNMP traps) can be sent to a network system or as e-
mail to a specified network administrator.
The integral Web server enables configuration and diagnostics
settings to be made using a standard browser (e.g. port con-
figuration). Statistical information can also be read out over the
Web server (e.g. port capacity utilization).
The following information is displayed by LEDs on site:
• Power
•
Port status
•
Data traffic
•
Signaling contact
•
