Design
The SCALANCE X204RNA and X204RNA EEC network access
points with rugged plastic or metal enclosure have been
optimized for installation on a standard mounting rail and for
direct wall mounting in different mounting positions.
The network access points with IP20 degree of protection
feature:
•
A 4-pole terminal block for connecting the redundant supply
voltage (2 x 24 V DC), or a 3-pole terminal block in the case of
the wide-range power supply unit
•
A row of LEDs to indicate the status information (power, link
状态，数据交换，电源，信号接触）
•
A 2-pole or 3-pole terminal block for connecting the floating
signaling contact in the corresponding voltage range
•
A SET button for on-site configuration of the signaling contact
The SCALANCE X200RNA devices are available with the
following port types:
•
100BaseTX, RJ45 connection;
RJ45 port with a data rate of 100 Mbit/s, with autosensing and
autocrossover function for the connection of IE FC cables via
IE FC RJ45 Plug 180 up to 100 m
•
100BaseTX, combo port (RJ45, SFP slot);
100 Mbit/s combo ports for direct connection to Industrial
Ethernet copper cables or glass fiber-optic cables
(multimode/singlemode fiber-optic cable);
如果使用组合端口的RJ45接口，则SFP插槽为
deactivated, and vice versa.

Function
•
Connection of non-HSR-enabled terminal devices to ring-
shaped networks
•
Transition from ring-shaped HSR networks to parallel PRP
network structures
•
Parallel data transmission by means of duplicate transmission

•
Uncrossed connecting cables can be used due to
Autocrossover function integrated in the ports
•
Easy diagnostics using signaling contact, SNMP and Web
浏览器
•
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

stations to be connected. They can be mixed electrically and
optically in star and line topologies.
When configuring the network, it is necessary to observe the
following boundary conditions:
•
Length of the TP cable between the network and
SCALANCE X-200RNA:
- Max. 100 m with IE FC cable and IE FC RJ45 Plug 180
- Max. 10 m using patches with TP cord
•
Length of the optical cables between the network and
SCALANCE X-200RNA
- Max. 5 000 m with Industrial Ethernet glass fiber-optic
cables (multimode)
- Max. 26 000 m with Industrial Ethernet glass fiber-optic
cables (singlemode)
•
IP address:
The IP address is assigned by means of the DHCP (Dynamic
Host Configuration Protocol). If there is no corresponding
server in the network, the IP address can be assigned using
the supplied software tool PST (Primary Setup Tool).
Commissioning and diagnostics
The SCALANCE X-200RNA Industrial Ethernet network access
points can be integrated into a network management system via
the standardized protocol SNMP (

rotocol). In the event of a fault in the device, error messages
(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 config-
uration). Statistical information can also be read out over the
Web server (e.g. port capacity utilization).
The following information is displayed on site by LEDs:
• Power
•
Port status
•
Data traffic
•
Signaling contact
•
HSR activity
The SCALANCE X-200RNA Industrial Ethernet network
access points can also be monitored using the floating signaling
contact.
