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 machinelevel 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.

SCALANCE X-200 Operating Instructions, 12/2011, A5E00349864-19

Preface

The only difference between the SCALANCE XF204IRT and the SCALANCE X-204IRT is the shape.

SCALANCE X-200 IRT PRO managed

In terms of functionality, the SCALANCE X200 IRT PRO switches are the same as the SCALANCE X-200 IRT managed switches listed above. The switch with degree of protection IP65/IP67 is designed for use outside a cabinet and has PROFINET-compliant connector technology (RJ-45 in compliance with IEC 61076-3-117 for X204 IRT PRO or SC RJ in compliance with IEC 61754-24-2 for X202-2P IRT PRO).

SCALANCE X-300

The main areas of application are high-speed plant networks with an interface to the Enterprise network. The SCALANCE X-300 managed plus product line combines the firmware functionality of the SCALANCE X-400 product line (without routing functions at the layer 3 level) with the compact design of the SCALANCE X-200 product line. The "managed plus" attribute means both enhanced management functions compared with the SCALANCE X-200 and enhanced firmware functionality.

SCALANCE X-400 modular

The switches of the SCALANCE X-400 product series are suitable for the construction of optical/electrical linear, ring and star topologies (10/100/1000 Mbps) for high-speed systems.

They have a modular structure, in which media modules and extender modules can be inserted in the switch as required. These expansions make as many as eight electrical and eight optical ports additionally available.

By supporting IT standards, for example, VLAN, RSTP, Layer 3, automation networks can be seamlessly connected to existing corporate networks.

The SCALANCE X-400 switches are ideally suited, for example, for process control systems such as PCS 7.

What is possible?

The devices of the SCALANCE X-200 product lines allow the cost-effective installation of Industrial Ethernet linear (bus), star and ring structures with switching functionality.

By using the “cut through” switching mechanism, the SCALANCE X-200IRT switches are ideal to meet the real-time requirements of PROFINET.

Cut through is not possible

● between a port set to 10 Mbps and a port set to 100 Mbps

● when two packets are to be sent at the same time on one port.

SCALANCE X-200

4 Operating Instructions, 12/2011, A5E00349864-19

Preface

One particular advantage of the SCALANCE X-200IRT switches in PROFINET networks is the integrated ERTEC. This gives priority to PROFINET packets when forwarding.

WARNING

When used under hazardous conditions (zone 2), the devices of the SCALANCE X-100 and SCALANCE X-200 product lines must be installed in an enclosure.

To comply with ATEX95 (EN 60079-15), this enclosure must meet the requirements of at least IP54 in compliance with EN 60529.

Network topologies / media redundancy

2.1 Network topologies

Switching technology allows extensive networks to be set up with numerous nodes and simplifies network expansion.

Which topologies can be implemented?

Bus, ring, or star topologies can be implemented with the X-200 IE switches.

Bus topology

Note

sure that the maximum permitted cable lengths for the relevant devices are not

Make exceeded. You will find the permitted cable lengths in the technical specifications.

For example, with the SCALANCE X202-2P IRT, X201-3P IRT, X200P IRT, X202-2P IRT PRO and X201-3P IRT PRO only 50 m POF or 100 m HCS cable may be used.

2.1 Network topologies

Figure 2-7 Ring topology with optical ring, example with SCALANCE X202-2IRT

To increase availability, optical or electrical bus topologies made up of X-200 IE Switches with an IE Switch X-200, IE Switch X-300, SCALANCE X414-3E, OSM version 2 or ESM version 2 configured as a redundancy manager can be closed to form a ring. The IE Switches X-200 are first connected over their ring ports to form a bus. The two ends of the bus are closed to form a ring by a switch operating in the redundancy manager mode. Devices of the IE switches X-200, X-300, X-400 product families, or OSMs / ESMs can be used as the redundancy manager. When a switch is used as the redundancy manager, the ring ports are isolated from each other if the network is operating problem-free.

The IE Switch X-200, IE Switch X-300, SCALANCE X414-3E, or OSM / ESM operating in the redundancy manager mode monitors the connected bus over its ring ports and switches the ring ports through if there is an interruption on the connected bus; in other words, it restores a functioning bus over this substitute path. Reconfiguration takes place within 0.3 seconds.

As soon as the problem has been eliminated, the original topology is restored; in other words, the ring ports in the redundancy manager are once again disconnected from each other.

2.2 Options of media redundancy

There are various options available to increase the network availability of an Industrial Ethernet network with optical or electrical linear bus topologies:

● Mesh networks

● Parallel connection of transmission paths

● Closing a linear bus topology to form a ring topology

2.3 Media redundancy in ring topologies

Structure of a ring topology

Nodes in a ring topology can be external switches and/or the integrated switches of communications modules.

To set up a ring topology with media redundancy, you bring together the two free ends of a linear bus topology in one device. Closing the linear bus topology to form a ring is achieved with two ports (ring ports) of a device in the ring. This device is the redundancy manager. All other devices in the ring are redundancy clients.

Figure 2-8 Devices in a ring topology with media redundancy

The two ring ports of a device are the ports that establish the connection to its two neighboring devices in the ring topology. The ring ports are selected and set in the configuration of the relevant device. On the S7 Ethernet CP modules, the ring ports are indicated by an "R" after the port number.

Note

ate the configuration of the devices to be connected to form a ring before you close the

Cre ring.

How media redundancy works in a ring topology

5HGXQGDQF\FOLHQWV

When using media redundancy, the data paths between the individual devices are reconfigured if the ring is interrupted at one point. Following reconfiguration of the topology, the devices can once again be reached in the resulting new topology.

In the redundancy manager, the 2 ring ports are disconnected from each other if the network is uninterrupted. This prevents circulating data frames. In terms of data transmission, the ring topology is a linear bus topology. The redundancy manager monitors the ring topology. It does this by sending test frames both from ring port 1 and ring port 2. The test frames run round the ring in both directions until they arrive at the other ring port of the redundancy manager.

SCALANCE X-200 Operating Instructions, 12/2011, A5E00349864-19

Network topologies / media redundancy

2.3 Media redundancy in ring topologies

An interruption of the ring can be caused by loss of the connection between two devices or by failure of a device in the ring.

If the test frames of the redundancy manager no longer arrive at the other ring port, the redundancy manager connects its two ring ports. This substitute path once again restores a functioning connection between all remaining devices in the form of a linear bus topology.

The time between the ring interruption and restoration of a functional linear topology is known as the reconfiguration time.

As soon as the interruption is eliminated, the original transmission paths are established again, the two ring ports of the redundancy manager are disconnected and the redundancy clients informed of the change. The redundancy clients then use the new paths to the other devices.

If the redundancy manager fails, the ring becomes a functional linear bus.

Media redundancy methods

The following media redundancy methods are supported by SIMATIC NET products for ring topologies:

● HSR (High Speed Redundancy)

Reconfiguration time: 0.3 seconds

● MRP (Media Redundancy Protocol)

Reconfiguration time: 0.2 seconds

Automatic configuration of the ring

The mechanisms of these methods are similar. With both methods, up to 50 devices can participate in the ring. HSR and MRP cannot be used in the ring at the same time.

If you configure your plant using STEP 7, you can only select MRP as the media redundancy method.

If you configure your devices with Web Based Management, CLI or SNMP, you can choose either HSR or MRP.

Media redundancy with IRT

For ring topologies in which MRP is activated, the "MRPD" function is activated automatically for IRT devices capable of IRT, if this is supported by the device.

● MRPD (Media Redundancy with Path Duplication)

For use only with SCALANCE X-200IRT

This procedure allows redundancy with IRT. You will find details in the section MRPD (Page 27).

SCALANCE X-200

Network topologies / media redundancy

2.4 MRP

The "MRP" method conforms to the Media Redundancy Protocol (MRP) specified in the standard IEC 62439-2 Edition 1.0 2010-02.

The reconfiguration time after an interruption of the ring is a maximum of 0.2 seconds.

Requirements

The following requirements must be met for problem-free operation with the MRP media redundancy protocol:

● MRP is supported in ring topologies with up to 50 devices. Exceeding this number of devices can lead to a loss of data traffic.

● The ring in which you want to use MRP may only consist of devices that support this function. This applies, for example, to the following devices:

– Industrial Ethernet switches

SCALANCE X-200 as of firmware version V4.0

SCALANCE X-200 IRT as of firmware version V4.0

SCALANCE X-300 as of firmware version V3.0

SCALANCE X-400 as of firmware version V3.0

– Communications processors

CP 443-1 Advanced (6GK7 443-1GX20-0XE0) as of firmware version V2.0

CP 343-1 Advanced (6GK7 343-1GX30-0XE0) as of firmware version V1.0

CP 1616 (6GK1 161-6AA00) as of firmware version V2.2

CP 1604 (6GK1 160-4AA00) as of firmware version V2.2

– Non-Siemens devices that support this functionality.

Further Siemens devices are planned that will support MRP.

● All devices must be interconnected via their ring ports.

● If you configure in STEP 7, MRP must be enabled on all devices in the ring (see "MRP configuration in PROFINET IO").

● If you configure with Web Based Management, CLI or SNMP, set all the devices in the ring to "MRP Client" or "Automatic Redundancy Detection". At least one device in the ring must have the setting "Automatic Redundancy Detection".

In their basic status, the "Automatic Redundancy Detection" mode is set on IE switches as default.

● The connection settings (transmission medium / duplex) must be set to full duplex and at least 100 Mbps for all ring ports. Otherwise there may be a loss of data traffic.

– To do this, set all the ports involved in the ring to "Automatic settings" in the "Options"

tab of the properties dialog during STEP 7 configuration.

– If you configure with Web Based Management, the ring ports are set automatically to

autonegotiation.

The following rules apply to a ring topology with media redundancy using MRP:

● All the devices connected within the ring topology are members of the same redundancy domain.

● One device in the ring is acting as redundancy manager.

● All other devices in the ring are redundancy clients.

Non MRP-compliant devices can be connected to the ring via a SCALANCE X switch or via a PC with a CP 1616.

2.5 MRPD

The redundancy procedure MRPD (Media Redundancy with Path Duplication)

The MRPD procedure is specified in IEC 61158 Parts 5 and 6 type 10 "PROFINET". It allows redundancy for PROFINET IRT.

In MRPD, the cyclic IRT frames are duplicated and sent to the recipient via different paths. The two redundant paths are planned in STEP 7. Two different paths are then available if the entire network or part of it has a ring topology.

Requirements

● All devices involved must support IRT.

● All devices involved must support MRPD.

Among the Industrial Ethernet switches, this means the following devices:

– SCALANCE X-200IRT as of firmware version 5.0

● STEP 7 as of version V5.5 SP1

Project engineering

MRPD can only configured in STEP 7 and there are no alternative configuration options.

To prevent loops forming and to ensure redundancy for other types of communication, MRP is always required for MRPD. If you activate MRP in STEP 7, products capable of IRT and MRPD use MRPD automatically.

The "High Performance" version of IRT must be used and the topology of the network must be configured.

2.6 HSR

The "HSR" method allows a reconfiguration time of 0.3 seconds following an interruption in the ring.

Requirements

The following requirements must be met for problem-free operation with the HSR media redundancy method:

● HSR is supported in ring topologies with up to 50 devices. Exceeding this number of devices can lead to a loss of data traffic.

● The ring in which you want to use HSR may only consist of devices that support this function. This applies, for example, to the following devices: X-400 IE switches, X-300 IE switches, X-200 IE switches and OSM / ESM.

● All devices must be interconnected via their ring ports.

● A device in the ring must be configured as redundancy manager by selecting the "HSR Manager" setting. You can do this with the button on the front of the device, Web Based Management, CLI or SNMP.

● On all other devices in the ring, either the "HSR Client" or "Automatic Redundancy Detection" mode must be activated. You can do this with Web Based Management, CLI or SNMP.

● In the basic status, the "HSR Client" or "Automatic Redundancy Detection" mode is set as default.

2.7 Redundant coupling of network segments

Coupling option

The coupling of two network segments shown here as an example is possible with X200IRT, X-300 and X-400 IE switches. This requires the standby function of these devices that can be set via the WEB interface or CLI.

If the standby function is enabled, this is signaled on X-200 IE switches by the RM-LED.

The SCALANCE X-200IRT can be operated either as an RM or in standby mode.
