Network topology and network configuration
The network topology can easily be adapted to the structure of
the plant with SCALANCE X-400 Industrial Ethernet switches.
The following network structures and combinations of structures
can be implemented:
•
Fast Ethernet and Gigabit rings with fast media redundancy:
To protect against failure of a transmission link or a switch,
as many as 50 X-400 switches cascaded in line can be
connected into a ring with a total length of up to 150 km using
multi-mode or 6,000 km using single mode. On the failure of
a transmission link or a SCALANCE X-400 switch in the ring,
the transmission path is quickly reconfigured due to the media
redundancy.
•
Several rings can be redundantly linked through the standby
function.
•
At the same time, SCALANCE X-400 supports redundant
connection of the ring structure to the corporate network with
Rapid Spanning Tree.
•
Star topology with SCALANCE X-400 switches:
The SCALANCE X-414-3E switch represents a star point
which can interconnect as many as 26 nodes or subnetworks
electrically or optically;
SCALANCE X408-2 can connect up to 8 nodes or
subnetworks.
When configuring the network, it is necessary to observe the
following boundary conditions:
•
Maximum line length between two modules for multi-mode
fiber-optic conductors:
- 3 000 m at 100 Mbit/s
- 750 m at 1 Gbit/s
•
Maximum line length between two modules for single-mode
fiber-optic conductors:
- 70 km at 100 Mbit/s
- 12 km at 1 Gbit/s
•
Maximum length of installation cable:
- 100 m at 100 Mbit/s with IE FC TP Cable 2 x 2 and
IE FC Plug 180
- Max. 90 m at 1 Gbit/s with IE FC TP cable 4 x 2,
IE FC RJ45 modular outlet and patch cable (10 m)
- 100 m at 1 000 Mbit/s with IE FC TP Cable 4 x 2 and
IE FC Plug 4 x 2
Commissioning and diagnosis
Setting options on the device itself:
•
Redundancy manager RM;
to establish a ring, a SCALANCE X-400 is switched to RM
mode. The Gigabit ports (electrical or – with media module –
optical) are preferably used as ring ports. When using in
optical rings with 100 Mbit/s, the ring ports can be configured
on one media module or on two media modules.
•
Signal mask;
the signal mask is set to the current status of the SCALANCE
X-400 (setpoint) by pushbutton operation. It defines which
ports and which voltage feeds are to be monitored. The signal
contact only reports an error when a monitored port or a
monitored feeder fails (deviation of setpoint/actual status).
Diagnostic options on site:
•
The following status information is displayed by LEDs on site:
- Port status
- Port mode (10/100/1 000 Mbit/s, full/half-duplex)
- Status of the two voltage feeders
- Signal contact status
- Signal mask (setpoint status)
- RM mode
- Standby mode
•
The status of the signal contact is routed externally by means
of floating relay contacts. This enables, for example, the
module to be monitored via an input module from a controller.
•
A PC or a programming device can be directly connected via
a serial interface or, with the X414-3E, also via an Ethernet
interface (out-band port). Operation is by means of
commands (Command Line Interface (CLI)).
•
Monitoring via the Industrial Ethernet network;
the following possibilities are available:
- Remote via standard browser (Web-based management):
Selection of SCALANCE X-400 switches via the network from
a PC with browser
- Remote via SNMP V1, V2c, V3:
Secure integration of SCALANCE X-400 switches via the
network into a network management station
- Remote via PROFINET IO diagnostics
- Standard diagnostic alarms can be configured in an easy,
familiar manner in STEP 7 and processed in SIMATIC.
The engineering outlay is drastically reduced for the PLC
and HMI through complete integration in the SIMATIC
system error message concept SFM.
