Preface

OSM/ESM with Network Management

As of firmware version 2.0, all Industrial Ethernet OSMs (Optical Switch Modules) and Industrial Ethernet ESMs (Electrical Switch Modules) have integrated management functions.

These functions provide you with simple methods of modifying settings on

OSMs/ESMs, monitoring OSMs/ESMs, and running network diagnostics. If you already have OSMs and ESMs, you can upgrade them with the network management functions by simply downloading new firmware via the serial port.

This user manual describes the functions of firmware version 2.3.5

Note

Upgrading OSMs version 1 (order number 6GK1105-0AA00) or ORMs is not possible.

The OSM/ESM allows three separate ways of using network management, all of which are possible at the same time:

S Web-Based Management (WBM); in other words, operation and diagnostics using an Internet browser.

S SNMP Management; in other words, parameter assignment and diagnostics from one or more management stations.

S A command interpreter (CLI - command-line interface) accessible both via the serial port of the OSM/ESM and using TELNET

With remote monitoring (RMON), the OSM/ESM provides you with a wide range of diagnostic functions for your network. You can, for example, record network load trends and visualize them on a network management console or you can configure the OSM/ESM to send traps (alarm messages) to notify you of faults and errors.


C79000-G8976-C137-08 i

Preface

Note

To use SNMP management, RMON and traps, you require a network management station. This is not supplied with the OSM/ESM.

Purpose of the Manual

This manual describes the network management functions of the Industrial

Ethernet OSM/ESM. It explains network management with SNMP, Web-Based

Management of OSM/ESM, and how to set parameters with the command interface.

Aims

Using network management on the OSM/ESM, you can also configure a redundant coupling allowing several rings or networks to be interconnected redundantly.

With this manual, you should be in a position to use the network management functions of the OSM/ESM.

Scope of the Manual

This manual is valid for the OSM/ESM with firmware version 2.3 and higher.

Notes for the Reader

How you use the manual depends on what you want to do...

S

You want to get to know the functions of the OSM/ESM. First, read the

OSM/ESM manual supplied with the device on CD. This manual can also be downloaded from the SIMATIC Customer Support Web site under entry number

8677203 at http://www4.ad.siemens.de/view/cs/en/8677203 .

S You want an overview of SNMP and Web-Based Management. Read the introduction in Chapter 1.

S

You want to know how to use the integrated command interpreter (CLI). This is explained in Chapters 2 and 3.

S

You want to control the OSM/ESM with an Internet browser or want to get diagnostic information from the OSM/ESM using a browser. You will find information on these topics in Chapters 2 and 4 of this manual. Trying out

Web-Based Management is the simplest way of familiarizing yourself with the management functions of the OSM/ESM.

S

You want to monitor the OSM/ESM from a network management station using

SNMP or want to use the RMON functions of the OSM/ESM. Read Chapter 5 in this manual.

Preface

Audience

This manual is intended for persons with the qualifications required for installation, operation, and programming of the described product.

If you want to control the OSM/ESM using Web-Based Management, you must be familiar with the basic functions of an Internet browser and be capable of making changes to the browser settings. You will find information on the settings required in Web browsers in the appendix to this manual. It is also assumed that you are already familiar with the functions of the OSM/ESM as described in the OSM/ESM manual /1/.

If you want to access the OSM/ESM from a management station using SNMP or want to use remote monitoring (RMON), it is assumed that you are familiar with operating the management station (for example, HP Open View or SNMPc from

Castle Rock) and that you know the basic mechanisms of SNMP and Ethernet switching.

Personnel Qualification Requirements

Only qualified personnel should be allowed to install and work on this equipment .

Qualified personnel as referred to in the operating instructions or in the warning notes are defined as persons who are familiar with the installation, assembly, startup and operation of this product and who possess the relevant qualifications for their work, e.g.:

S Training in or authorization for connecting up, grounding or labeling circuits and devices or systems in accordance with current standards in safety technology;

S

Training in or authorization for the maintenance and use of suitable safety equipment in accordance with current standards in safety technology;

S

Possible Security Risks on Standard IT Interfaces

In various SIMATIC NET components such as OSM/ESM, a wide range of parameter assignment and diagnostic functions (for example Web Server, Network

Management) are available over open protocols and interfaces. The possibility of unauthorized misuse of these open protocols and interfaces by third parties, for example to manipulate data, cannot be entirely excluded.

When using the functions listed above and these open interfaces and protocols (for example, SNMP, HTTP, Telnet), you should take suitable security measures to prevent unauthorized access to the components and the network particularly from within the WAN/Internet.

Introduction

1.1

Network Management with SNMP

The Industrial Ethernet OSMs (Optical Switch Modules) and Industrial Ethernet

ESMs (Electrical Switch Modules) have SNMP and Web Based Management. This chapter briefly explains the basics of network management with SNMP and

Web-Based Management.

In the past, homogeneous office networks installed with components from one manufacturer could also be maintained and administered with the proprietary management systems provided by the manufacturer. Due to the constant increase in the size of networks and internetworking involving the widest variety of different network types (for example an intranet), these proprietary management systems often reach their limits.

The problem was solved in the eighties with the introduction of the Simple Network

Management Protocol (SNMP) by the Internet Activities Board (IAB). This standard was readily accepted by the network industry and solves the essential tasks of a network management system.

1.1.1

Function

Client/Server Model

A network management system that uses SNMP works according to the client/server model. The management station or simply manager (client) can query status information from the components it is responsible for controlling. These components can be widely differing devices within the network system, such as network components, switches, hubs or DTEs such as workstations, PCs or network printers.

Agent

An agent (server) is installed on all of these devices. This agent that is normally implemented on the components as software functionality provides the

management system with station-specific data or receives configuration data.

Access to the components by the management station (both reading and writing) is cyclic and uses the network management protocol (SNMP).

The station data provided by the agent is stored in structured form in the MIB

(Management Information Base, see below).

The agent not only has the task of providing data when requested by the management station, but can also react event-driven by sending a message known as a trap to the management station.

Communication between the management station and agents involves only an insignificant increase in overheads on the network during operation.

Introduction

1.1.2

Communication

Protocol

SNMP uses the connectionless protocol UDP (User Datagram Protocol).

Getting Information

To read the required status information, the manager sends a Get request to the agent of the device. The addressed component answers the request with a

Response message.

Making Settings

To change the current configuration of a managed device, the manager sends a

Set request.

Status changes can be notified to the manager event-driven and without polling by the agent sending a Trap message.

Management for Industrial Networks

MIB

The MIB is a data structure made up of different variables (management objects) that can be polled or set by the management system. The variables used for polling are described in a language independent of the target system.

Thanks to the standardized MIBs and access mechanisms used by all manufacturers, it is possible to monitor and control a network with components from a wide range of vendors. Device views allow the management objects to be displayed graphically in the management system. If there is no device view available for the component, the objects are represented row-oriented using an

MIB browser.

If additional data is required for network monitoring, this can be defined in private

MIBs by the vendors. This allows values to be polled that are not included in the standard.

Introduction

1.2

Network Management for Industrial Networks

The trend towards larger and larger structures in industrial networks has been apparent for some time. Vertical integration, in other words the growing together of industrial networks and office networks, allows transparent access to all data but also requires integrated diagnostic functions. To meet the new requirements of this situation, the SIMATIC NET signaling concept using a signaling contact has been extended to include network management.

1.2.1

Signaling Concept

All active Industrial Ethernet network components have a signaling contact. Using this digital contact, the network component provides a group signal with which various statuses can be reported. Using an input module, this signal can then be passed on to operator control and monitoring systems (for example WinCC) where it can be visualized. This allows problems in a network to be recognized early and eliminated. The signaling concept with a signaling contact is a reliable and adequate monitoring system for small and medium sized networks.

1.2.2

Network Management

For industrial networks extending over large company complexes and linked to office networks, the signaling concept outlined above is not always suitable for monitoring the network. Moreover, there are not always suitable I/O cards available that are capable of reading in these digital signals.

For such networks, SIMATIC NET provides network management functionality based on SNMP for network monitoring in the OSM/ESM product range.

This allows the new switch modules to be managed, monitored and tested with every network management tool available on the market, for example, HP Open

View, SunNet Manager or SNMPc from Castle Rock.


C79000-G8976-C137-08 1-5

Introduction

1.2.3

Web-Based Management (WBM)

To allow users to introduce network management cost-effectively, Web-Based

Management is available for network management and diagnostics with the

SIMATIC NET switch modules.

With the aid of Web-Based Management, it is possible to address individual network nodes or DTEs using an Internet browser such as the Netscape

Communicator or Internet Explorer. By using the browser technology, access to network nodes on different platforms such as WinNT or UNIX is possible. Since the user is generally familiar with a browser, network management can be learned quickly and easily.

To allow Web-Based Management, an applet is stored on the OSM/ESM modules from SIMATIC NET that is loaded with the browser. This applet accesses data from the MIB of the addressed module dynamically and represents it graphically in the browser.

Web-Based Management allows access to only one network node at a time. An overview of all the nodes in the network and their topological arrangement is possible only with an extensive SNMP-based network management tool.

1.4

Command Interpreter (CLI)

In addition to the Web-Based Management, you can also change or query all the important parameters of an OSM/ESM using a terminal with a V24 interface (for example a PC with the Windows Hyperterminal program). The terminal is connected to the serial port of the OSM/ESM. The functions of the OSM/ESM are manipulated using a simple command interpreter (CLI, Command-Line Interface).

TELNET also provides the same functionality.

Setting the IP Addresses

You can set the IP configuration (IP address, subnet mask, gateway) using the following alternative methods:

S Manually using the Command Line Interface (Chapter 3)

S Manually using SIMATIC NET NCM PC, SIMATIC STEP 7 or the Primary Setup

Tool (Section 2.14)

S Automatically using BOOTP/DHCP (Section 2.13)

When supplied, the OSM/ESM has no IP address and BOOTP/DHCP is activated.

To use Web Based Management, Telnet, SNMP, E-Mail, TFTP

(saving/downloading configuration data, firmware update over Ethernet), the

OSM/ESM must have an IP address.

Important OSM/ESM Functions

C79000-G8976-C137-08 2-1

Important OSM/ESM Functions

2.1

Autonegotiation

In the autonegotiation mode, an electrical OSM/ESM port sets itself automatically to the transmission rate (10/100 Mbps) of the connected partner device. If the partner device also supports autonegotiation, the devices further negotiate whether they will exchange data in the half-duplex or full-duplex mode and full-duplex flow control.

Note

If an OSM/ESM port that supports the autonegotiation mode is connected to a partner that does not support this mode, the port of the partner device must be set to the half-duplex mode.

2-2


C79000-G8976-C137-08


2.2

Autocrossover

Electrical OSM/ESM ports with the autocrossover function are capable of crossing over the send and receive signals internally in the port. This means that straight-through or crossover TP cables can be used without causing problems.

To use the autocrossover function:

S

At least one of the two ports must support the autocrossover function.

S

The autonegotiation mode must be set on the port providing the autocrossover function.

OSM TP22, ESM TP40 and all OSMs/ESMs with order numbers ending in “10” (for example, 6GK1105-2AA10) provide autocrossover functionality.

Notice

Please note that even when using straight-through cables, an invalid loop can result in the Ethernet network, for example, by linking two ports on one OSM/ESM.

Such a loop can lead to network overload and network failures.

2.3

Transmission Rate and Duplicity

The transmission rate and/or duplicity of the electrical ports can also be set by the user with network management functions. The values are shown in Table 2-1 below.

The transmission rate and duplicity of a port set by the user only comes into effect if autonegotiation is turned off for the port.

Table 2-1 Transmission Rate and Duplicity

C79000-G8976-C137-08 2-3


2.4

Factory Defaults and Protected Settings

Defaults

The OSM/ESM had default settings made in the factory (see 4.7.3Factory

Defaults). The user can query and modify these defaults with WBM, the CLI or

SNMP.

The screenshots of the WBM dialogs in Chapter 4 show the default settings. You will find further default settings in the private MIB file (see Section 4.7.3).

Restore Memory Defaults and Restart

Using WBM or the CLI, a command is available with which it is also possible to restore some of the factory defaults.

Apart from the protected settings, all the settings are restored to the factory setting.

Protected Settings

The protected settings of the OSM/ESM are not modified when you restore the factory defaults to avoid having to make settings again unnecessarily.

The protected settings are as follows:

IP address, subnet mask, default gateway, system name, system location, system contact.

Restore Factory Defaults

Using WBM or the CLI, a command is available with which it is also possible to restore the factory defaults. The factory defaults are also restored if you trigger a

RESET with the button on the front panel of the OSM/ESM, see /1/.

The protected settings are also reset!

If you trigger the function using the CLI or WBM, the device does not start automatically. You will be prompted to start the device manually. Before you start manually, you have the opportunity of reconfiguring the device. To be able to communicate with the device later over the LAN, it is important to specify the IP address.

Notice

If the device operates as standby master or standby slave, and the user configuration of the linking signal lines does not match the default factory setting, make sure that you disconnect the signal line(s) before starting the “Factory Default” function.

2-4


C79000-G8976-C137-08


2.5

Filtering Database (FDB Table)

The FDB (Filtering Database ) table is used by the OSM/ESM to decide which port or ports a received packet is transferred to. The FDB table of the OSM/ESM can hold up to 7000 addresses.

2.5.1

Entries in the FDB Table

The FDB table contains two types of entries (addresses):

S

Static MAC addresses: These can be entered and deleted by the user with

WBM or SNMP.

S Learned MAC addresses: These are learned by the OSM/ESM automatically; in other words they are entered in the FDB table when the module receives corresponding packets. The OSM/ESM makes an entry in the FDB table indicating the port at which it learned the address; in other words, the port to which the node with the corresponding MAC address is connected. After making this entry, it then passes all received packets for this node to the relevant port. This mechanism reduces network load. Automatic learning is only possible when lock disabled is set for the relevant OSM/ESM port, see

Section 2.6. This is the default setting.

Note

S The OSM TP22 and ESM TP40 do not support static entries in the FDB table.

S Static addresses are retained when the OSM/ESM is turned on and off or restarted; learned addresses are deleted.

S In the redundant manager (RM) mode, no static address entries are possible.

S No static unicast addresses can be entered for the ring ports.

S If a port is used for a redundant network link (master and standby link), there must be no static addresses entered for it.


C79000-G8976-C137-08 2-5


2.5.2

Displaying and Deleting FDB Entries, Aging

The entries in the FDB table can be displayed by the WBM, see Section 4.10.1.

Static addresses can also be entered or deleted in WBM.

If aging is activated (default), a learned entry (address) is automatically deleted in the FDB table when no packet with this source address is received within the

aging time.

Aging prevents addresses that are no longer up to date from remaining in the FDB table permanently. “Aged entries” can, for example, mean that a node that has been connected to a different OSM/ESM port is no longer obtainable because the packets intended for it are still sent to the original port.

In WBM and in the CLI, aging can be enabled and disabled and the aging time can be modified. The default setting for the aging time is 40 seconds.

2.5.3

Reaction to Spanning Tree Frames

When an OSM/ESM is interfaced to a higher - level office network, users often require this interface to be implemented redundantly. The company network, however, uses third - party components that do not support fast OSM/ESM redundancy mechanisms (forming rings and standby links). At other points in the office network, a mesh topology is used and the resulting loops are eliminated by the spanning tree protocol (IEEE 802.1D).

As of firmware version 2.3.5, OSMs/ESMs are capable of evaluating spanning tree frames that report modified configurations in the office network. This allows an

OSM/ESM ring to interface redundantly with an office network based on spanning tree.

During configuration changes (triggered by topology change events) made in a connected spanning tree office network, an OSM/ESM reduces its aging time. As a result, the MAC addresses of all stations (for example PCs) from which no further frames are received during this shortened time are removed from the address table. Stations that use new or modified network paths following a change in the configuration can therefore be reached again more quickly. On completion of the configuration changes, the OSM/ESM changes back to normal operation.

2-6


C79000-G8976-C137-08


Note

The OSM/ESM passes on all spanning tree frames regardless of the function described above. The OSM/ESM itself does not send any spanning tree frames.

The times involved in configuration changes depend on the spanning tree configuration and the network topology. The actual time required to change the configuration must be determined based on tests.

During modification of a configuration, ”Configuration BPDUs” (configuration frames) with the ”TC” Flag (”topology change” bit) set are sent repeatedly in a connected spanning tree network . Based on these frames, an OSM/ESM recognizes the duration of the changes to the configuration.


C79000-G8976-C137-08 2-7


2.6

Locked Ports

Locking

Locking is used to make sure that only packets from authorized stations are passed on by the OSM/ESM.

Lock Enabled

If the lock enabled function is activated for an OSM/ESM port, the OSM/ESM only passes on packets received at this port if the source address exists in the FDB table. All other packets are discarded. Learning new addresses is also disabled on this port; in other words, if a packet with a new source address is received, this address is not included in the FDB table of the OSM/ESM.

Addresses that have already been learned, are deleted automatically if aging is activated (see Section 2.5.2). A restart will force all learned addresses to be deleted immediately.

Lock Disabled

If lock disabled (default setting) is set, the OSM/ESM passes on packets with an unknown source address received at a port (in other words an address that does not exist in the FDB table of the OSM/ESM). New source addresses are automatically learned on this port; in other words, they are entered in the FDB table.

Programming Authorized Nodes

If you only want the packets from certain authorized nodes to be passed on by the

OSM/ESM, follow the steps outlined below:

1. Enter the MAC addresses of these nodes and the number of the port to which they are connected in the FDB table of the OSM/ESM using WBM.

2. Set the port to lock enabled.

3. Run an OSM/ESM restart using WBM to delete the learned entries in the FDB table and to save the configuration. The static addresses in the FDB table are retained when you restart.

Note

S The ring ports cannot be configured with Lock enabled.

S If a port is used for a redundant network link (master and standby link), it must not be configured with Lock enabled.

2-8


C79000-G8976-C137-08


2.7

Mirroring

Mirroring for Diagnostics

Mirroring allows you to mirror (copy) the bi-directional data traffic to an OSM/ESM port (mirrored port) to another OSM/ESM port (monitor port) and to record it with a protocol analyzer for diagnostic purposes.

Settings

You can set the mirrored and monitor port and activate the mirror function both with the command-line interface or using WBM. Ports 1 to 6 of the OSM/ESM can be used as the monitor port.

With the OSM TP22 and ESM TP40 variants, only ports 1 and 2 are permitted as the monitor ports.

Mirroring Active

If the mirroring function is activated and if the monitor port has a valid connection to the attached protocol analyzer, the port LED of the monitor port on the

OSM/ESM flashes quickly (4 x short with pause).

Note

Please remember to turn off the mirroring function if you connect a normal DTE to the monitor port.


C79000-G8976-C137-08 2-9


2.8

Traps

Trap Messages

If certain events occur, the OSM/ESM can generate (SNMP) trap messages and send them to up to 10 different nodes, for example management stations. By configuring the management station, the traps can be displayed on the user interface. An interpreted display is possible only when the corresponding MIB files can be evaluated by the management station. For example, to obtain a plain language display of special OSM/ESM functions, the private OSM/ESM MIB file must be loaded (see Section 4.7.3).

Issuing Traps

If the trap function is activated, traps are issued by the OSM/ESM automatically in the following situations:

Standard Traps (RFC 1157)

S After powering up or restarting.

S At link up, link down; in other words, when the valid connection to the DTE at a port is interrupted or reestablished.

S If an SNMP authentication error occurs; in other words, when a network management station or the Internet browser attempts to access the OSM/ESM using SNMP requests with the wrong access permission (community name).

RMON Traps (RFC 1757)

S When certain limit values are violated (high, low) that were configured earlier on the OSM/ESM by a network management station using RMON.

OSM/ESM-Specific Traps

S

When the OSM/ESM ring is opened/closed by the redundancy manager

(OSM/ESM in the RM mode), see /1/.

S When there is a switchover between the standby master and standby slave in a redundant coupling, see /1/.

S If the error state changes, see /1/.

S When one of the two power supplies of the OSM/ESM is turned on or off during operation.

Enabling/Disabling Traps

The issuing of traps can be enabled or disabled by WBM or the command-line interface.

2-10


C79000-G8976-C137-08


2.9

E-Mail Function

The OSM/ESM has an E-mail function with which an E-mail can be sent automatically (for example to the network administrator) if an alarm occurs. If the

E-mail function is activated, the OSM/ESM sends an E-mail in the same situations that lead to a trap being issued (see Section 2.8). The E-mail includes the identification of the sending OSM/ESM and a description of the cause of the alarm in plain language. For networks with only a few nodes, this allows simple centralized network monitoring to be implemented on the basis of an E-mail system. When an E-mail fault message arrives, the WBM can be started by the browser based on the identification of the sender so that further diagnostic information can be obtained.

To use the E-mail function, the following requirements must be met:

S The E-mail function is activated on the OSM/ESM and the E-mail address of the recipient is configured.

S The E-mail function is activated for the particular event (event configuration, activated for all events as default).

S

There is an SMTP server in your network that can be reached by the

OSM/ESM.

S

The IP address of the SMTP server is entered on the OSM/ESM.

The E-mail function can be activated by WBM or the command-line interface.

Note

Depending on the properties and configuration of the SMTP server, it may be necessary to adapt the “From” box for the E-mails. Please check with the administrator of the SMTP server. You can specify the “From” box using WBM,

CLI or by direct SNMP access.

Unless modified, the OSM/ESM uses the following address:

<device_type>@<IP_address>

For example, [email protected]


C79000-G8976-C137-08 2-11


2.10

Event Log Table

Events are entered chronologically in the event log table (log book) of the

OSM/ESM.

The events include:

S all events reported, including those via E - mail and trap,

S additional error messages if an E - mail server (SMTP) is not accessible or rejects the E - mail of an OSM/ESM.

The event log table can be read out using the command line interface (see section

3.5) over the Web Based Management (see Section 4.7.5) or using direct SNMP access. It can hold a maximum of 200 entries. When the number of entries reaches 201, the oldest entry is deleted (ring buffer).

2-12


C79000-G8976-C137-08


2.11

Time of Day and Time - of - day Synchronization

The OSM/ESM has two times:

1. System Up Time:

The time since the OSM/ESM was last restarted. The system up time is added to every E - mail and every entry in the event log table. After 497 days, the system up time starts again at 0. This oberflow results from the range of values of the standard MIB object (OID 1.3.6.1.2.1.1.3).

2. Date and Time of Day:

The date and time of day can be set on the OSM/ESM either manually using a

CLI command or automatically using SIMATIC time - of - day frames. Once the date and time of day have been set after restarting the device, the date an time - of - day information is added to E - mails and every event in the event log table. The date and time of day are NOT buffered if the device is turned off.

The OSM/ESM evaluates the cyclic multicast frames of a SIMATIC time transmitter and sets the date and time of day accordingly. This allows an absolute time to be assigned to reported events.


C79000-G8976-C137-08 2-13


2.12

Flow Control

Flow control is a mechanism that reduces the risk of data loss in the network resulting from overload.

The OSM/ESM supports two flow control mechanisms:

S Half Duplex Flow Control (Back Pressure) for ports operating in the half duplex mode. With this type of flow control, the OSM/ESM reduces the packet rate received at a port if there is overload in the network by generating additional collisions.

S Full Duplex Flow Control complying with the IEEE 802.3x standard for ports operating in the full duplex mode. If there is overload, the OSM/ESM generates pause packets that stop or re-enable the sending of new packets by the connected partner device. This is only possible when the DTE supports full duplex flow control.

Half and full duplex flow control can be activated separately for each port of the

OSM/ESM. If the OSM/ESM port is operating in the autonegotiation mode, the devices automatically negotiate whether or not the full duplex flow control is activated. It is also possible to deactivate flow control for all ports of the OSM/ESM at the same time.

Note

As default, full duplex flow control is deactivated. If you activate this, remember that this can delay time-of-day synchronization frames.

2-14


C79000-G8976-C137-08


2.13

BOOTP/DHCP

If there is a BOOTP or DHCP server in your network, the OSM/ESM can automatically obtain the following from the server:

S the IP address,

S the subnet mask,

S the IP address of the default gateway,

S the IP address of the TFTP server,

S the configuration file (Section 2.17) / or the firmware file name

If the BOOTP/DHCP function is activated on the OSM/ESM (default), BOOTP and

DHCP are always started after starting up the device.

BOOTP and DHCP can only be activated/deactivated together. When started, the

OSM/ESM sends both BOOTP and DHCP frames. If a BOOTP and a DHCP server reply in the network, the DHCP server will be given priority by the

OSM/ESM.

Note

The BOOTP/DHCP process delays the startup of the device by approximately 40 seconds if the BOOTP/DHCP server is not obtainable. For this reason,

BOOTP/DHCP is deactivated as soon as an IP address is set using WBM, CLI, direct SNMP access or the Primary Setup Tool.

Note

DHCP provides a mechanism that allows a client to lease an IP address for a limited lease time. When the lease time expires, the OSM/ESM can no longer be contacted using its previous IP address. If you use DHCP, please check the

(default) settings of the DHCP server regarding the lease time.


C79000-G8976-C137-08 2-15


2.14

IP Configuration Using SIMATIC NET NCM PC, SIMATIC STEP 7 or the Primary Setup Tool

Just as several other SIMATIC NET products, the OSM/ESM also supports IP configuration (IP address, subnet mask, gateway) using SIMATIC NET NCM PC,

SIMATIC STEP 7 or the Primary Setup Tool.

For more detailed information, refer to the documentation of the relevant product.

Note

S SIMATIC NET NCM PC and SIMATIC STEP 7 support IP configuration as of version 5.2. To configure an IP address, the SOFTNET for Industrial Ethernet option is also required.

S Assigning the IP address 0.0.0.0 to an OSM/ESM using SIMATIC NET NCM

PC, SIMATIC STEP 7 or the Primary Setup Tool has the effect that

BOOTP/DHCP is activated and BOOTP/DHCP is started immediately (without a restart of the device).

S Changes to the IP configuration using SIMATIC NET NCM PC, SIMATIC STEP

7 or the Primary Setup Tool become valid immediately without a restart on the

OSM/ESM.

In contrast, changes to the IP configuration or to BOOTP/DHCP using the

Command Line Interface, Web Based Management or SNMP only take effect after a restart of the device.

S

The Primary Setup Tool is available from Siemens Automation and Drives

Service & Support on the Internet under entry ID 14929629. You will find this entry at: http://www4.ad.siemens.de/view/cs/de/14929629

2.15

TELNET

With TELNET, you can operate the CLI of the OSM/ESM via the LAN/Internet. You can start a TELNET link to the OSM/ESM, for example, by clicking on the console icon in the login window of the OSM/ESM WBM, see Chapter 4.

Note

A maximum of 3 CLI links (serial + LAN) are possible at the same time.


C79000-G8976-C137-08 2-17


2.16

Extended Redundant Configuration

Redundant Coupling

With OSMs/ESMs (except for the OSM TP22 and ESM TP40), you can implement redundant links, see /1/. A redundant coupling is created using two OSMs/ESMs, one of which is set to the standby slave with the DIP switch (”Stby on”) while the other operates as the standby master. The standby-sync ports of both

OSMs/ESMs are interconnected using an ITP XP standard cable 9/9, see Figure

2-1.

In the factory default setting, port 1 is monitored by the standby master. In problem-free operation, data are transferred to the neighboring ring (network) via this port while there is no data exchange via port 1 of the standby slave.

Extended Redundant Configuration with Network Management

The extended redundant configuration of the OSM/ESM (with the exception of the

OSM TP22 and ESM TP40) allows up to 8 rings or networks to be coupled redundantly with two OSMs/ESMs (see also /1/)

With network management (for example in WBM), each port of the standby master and standby slave can be configured as a standby port, see Figure 2-2. The other ports can be used as “normal” OSM/ESM ports.

In problem-free operation, only the standby ports of the standby master are active and handle data exchange. If the standby master or the link of one of the standby ports of the master fails, all standby ports of the master are disabled and the standby ports of the slave activated so that a functioning configuration is re-established.

Note

Please remember that the same ports on the standby master and standby slave must be configured as the standby ports. If an optical port of the OSM ITP62

(order number 6GK1105-2AA00)is used in an extended redundant coupling, it must have at least hardware version 2.

Observer Function

The observer function provides further opportunities for error diagnostics and error protection for redundant rings. It allows malfunctions of the redundancy manager or bad configuration of a redundant ring to be monitored. The Observer is also capable of opening the connected ring when the errors are detected (portection mode). The function is optional and as default deactivated.

When creating a ring with the Observer, remember the following:

S

The second ring port of the redundancy manager (port 8 on 8-port

OSMs/ESMs, port 4 on 4-port OSMs/ESMs) must be connected with the first ring port of the Observer (port 7 on 8-port OSMs/ESMs, port 3 on 4-port

OSMs/ESMs) (see Figure 2-3).

S The OSM/ESM acting as the observer must be switched to the observer mode using the Command Line Interface (CLI), the command syntax for the observer is explained in Chapter 3.

S The firmware version of both the observer and redundancy manager must be

V2.2 or higher.

Observer Error Messages

Observer error messages are signaled using the method (path) selected for alarm events (Fault State Change - see Agent Event Configuration). These methods are

E-mail, trap and/or event log table entry. The message text is: “Observer detected error”.

The status (see Table 2-2) is entered in the event log table and can also be displayed in the CLI OSM menu with the ”Info” command. The display may be delayed by several seconds.

Automatic Download of the Configuration

If the file name and folder of a configuration file is specified on the BOOTP server or DHCP server, the BOOTP/DHCP client of the OSM/ESM can trigger an automatic download of the configuration data over TFTP.

Requirements

The BOOTP and TFTP servers must be configured and started on the same station under one IP address. BOOTP must be activated on the OSM.

The following additional settings are necessary:

S on the BOOTP server or DHCP server:

The file name of the configuration file and path to the folder

S On the OSM:

The entered name of the configuration file corresponds to the factory setting

“Not Defined Yet”.

When an OSM/ESM is started with the factory settings, a BOOTP query is started.

The OSM/ESM then receives the following information from the BOOTP server:

S

IP address, subnet mask and default gateway of the OSM/ESM

S IP address of the TFTP server (identical to the IP address of the BOOTP server)

S File name of a firmware or configuration file.

The OSM/ESM then loads the first bytes (identification data) of the file ”file name” from the TFTP server and checks whether this is a suitable configuration file based on this identification data. If the file is suitable, this OSM/ESM configuration is accepted by the OSM/ESM and the file name is saved as the “Configuration File

Name”. If the file is not suitable, the OSM/ESM assumes that the file name supplied via BOOTP/DHCP is a firmware file and enters it as the firmware file name.

When the OSM/ESM restarts, the configuration file is not automatically loaded because the name of the configuration file is stored on the OSM/ESM and does not correspond to the factory setting “Not Defined Yet”.

Note

Please note that the IP configuration received from the BOOTP server or DHCP server is retained and the IP configuration from the configuration file is not adopted. The IP configuration contained in the configuration file is only adopted when the file is loaded manually.

C79000-G8976-C137-08 3-1

Command Interpreter (CLI)

3.1

Overview

The CLI is required for the following:

S

To set the IP address and the subnet mask of the OSM/ESM. This information is necessary so that the OSM/ESM is obtainable with SNMP, Web-Based

Management or TELNET.

S

To assign new passwords for the OSM/ESM.

S

To read or modify OSM/ESM parameters as an alternative to SNMP or


The CLI can be accessed via the serial port of the OSM/ESM or using TELNET.

(The OSM/ESM must already have an IP address/subnet mask. After a new IP address has been assigned, TELNET must be restarted.)

Note

To make sure that your last configuration changes are saved, use the “Restart” command in the CLI or WBM before you turn off the power to the device. All configuration changes are entered in the flash memory after approximately one minute or following a restart.

3.2

Password Protection

Access using the CLI is password-protected. You can log in as administrator or as user (with different passwords). An administrator can read and modify

OSM/ESM parameters, a user can only read OSM/ESM settings (see Service menu in Section 3.5)

3-2


C79000-G8976-C137-08


3.3

Installing the CLI

The CLI is accessible via the serial port of the OSM/ESM or via TELNET.

Serial Port

Connect a PC (or if preferred a VT100 operator terminal) to the serial port of the

OSM/ESM. Use the Hyperterminal program available under Windows on the PC.

(Please refer to the instructions in Appendix B of this manual).

PC

OSM ITP 62

Null modem

Figure 3-1 CLI Via the Serial Port

CLI via TELNET

The CLI functions are also available using TELNET, see Figure 3-2. The

OSM/ESM must already have a valid IP address and a subnet mask. If the operator PC is in a different subnet on the OSM/ESM, the default gateway must also be configured on the OSM/ESM before access is possible using TELNET.

PC

OSM ITP 62

LAN/Internet

Figure 3-2 CLI via TELNET

A TELNET link to the OSM/ESM can, for example, be started in the login window of Web-Based Management by clicking on the console icon, see Chapter 4.


C79000-G8976-C137-08 3-3


3.4

Login

Once the connection has been established via the serial port or using TELNET, the following prompt appears:

Login:

Type in admin (for administrator) or user (for user) according to your access permission and then press [Return].

Password:

Enter your administrator or user password and press [Return].

Note

If no new passwords were assigned (factory default), the valid password is admin for administrator and user for user.

If the password is lost, the OSM/ESM can be reset to the default values by pressing the button on the front panel, see Section 2.4. The passwords admin or user are then valid again.

Please note that after logging in via the serial port, commands can be entered until you log out with the exit command. Disconnecting the cable does not close the session.

The CLI then displays the start menu and the prompt

CLI>

You can now activate the commands of the CLI.

3-4


C79000-G8976-C137-08


3.5

CLI Commands

This section explains the commands of the CLI, their functions and syntax.

Commands

The commands that are available depend on the access level; in other words, whether you logged in as user or as administrator. Table 3-2 contains an overview of the commands available for the administrator and user. The command-line interface provides functions comparable with those available in Web-Based

Management. You should therefore also refer to the detailed explanations of the parameters available in Web-Based Management in Chapter 4.

Symbols

Table 3-1 explains the symbols used with the CLI commands.

Table 3-1 Symbols of the CLI Commands

Symbol

<>

[ ]

()

Meaning

Mandatory entry

Used to separate possible alternative input values in a command. The factory default is shown on the extreme left. Only one of the possible values can be selected.

Example:

aging <E|D>: You must either enter aging E (aging enabled) or

aging D (aging disabled), E is the default.

Optional parameters. These options are used, for example, to be able to address several port numbers at the same time. The individual optional extensions are separated by commas; you can address groups using dashes.

Example:

If you enter the numbers 2,5 - 8 in the [ports] field of a command, this command applies to ports 2 and 5 to 8.

Description of the commands.

Fast Input

To enter a command quickly, write the first letter or letters and then press the [Tab] key. If the required command is not shown, press the [Tab] key again.


C79000-G8976-C137-08 3-5


Example

The following example illustrates how to use CLI commands.

Example:

The command status <E | D> [ports] is used to enable or disable OSM/ESM ports. The user enters the following: status followed by a blank and then the mandatory setting either E (= enable) or D (= disable) and then the optional port numbers as described in Table 3-1. If you do not enter a port number, the command applies to all ports.

S

To enable the ports 2, 3, 4 to 6:

Enter status E 2,3,4 - 6 and confirm with [Return].

S

To disable ports 1 and 4 to 6:

Enter status D 1,4 - 6 and confirm with [Return].

Note

The example refers to the 8 - port variant of the OSM/ESM.

CLI Menus and Description

The following tables contain the commands, CLI menus and a brief description. If there are several alternatives for a command parameter, the default is always the value to the extreme left.

Web-Based Management (WBM)

4.1

General Introduction

The OSM/ESM includes integrated Web-Based Management; in other words, it can be operated using an Internet browser. The modules are operated using a

Java applet stored on the OSM/ESM that is loaded by the browser. To access the

OSM/ESM, the IP address must be entered in the address field of the browser. If there is a DNS server in your network that can interpret the address of the

OSM/ESM, you can also access the module using the logical name.

4.1.1

4.2

Requirements

To access an OSM/ESM using WBM, the following requirements must be met:

Internet Browser

You require a PC with an Internet browser. As the Internet browser, we recommend a Netscape Communicator, Version 4.7 or a Microsoft Internet

Explorer, Version 5.0 or higher.

Before your Internet browser will work with the OSM/ESM, you must make the correct settings in the browser. For more information, refer to Appendix A of this manual.

Address Settings

If you operate your OSM/ESM in the same subnet as your PC/Internet browser, you must first make the following settings via the CLI (serial port of the

OSM/ESM):

S The IP address of the OSM/ESM. (The IP address can be set with the CLI command ip <IP address> , see also Section 3.5). As an option, the IP address can also be assigned automatically using a BOOTP server, see also

Section 2.13.

S The subnet address of the OSM/ESM (CLI command subnet < IP address>, see also Section 3.5).

If your PC/Internet browser is in a different subnet from the OSM/ESM (subnets connected by a router), you must also set:

S

The default gateway of the OSM/ESM (CLI command gateway < IP address>

).

As an option, these parameters can also be loaded from a BOOTP/DHCP server.

4.4

Access Using Web-Based Management

You can access the OSM/ESM using WBM as follows:

1. Open the Internet browser.

2. Enter the IP address or the URL of the OSM/ESM in the address box of the

Internet Browser as follows:

http://<IP address of OSM/ESM> e.g. http://142.11.7.8

and confirm with [Return].

3. When the “Login” window appears (Figure 4-2), select admin or user in the

Login ID box (to select the access level). If you log in as administrator

(admin), you have both write and read access; in other words you can change settings on the OSM/ESM. As user, you only have read access; in other words you can read out settings, counter values etc. but cannot modify them.

Figure 4-2 “Login” Window

In the login window, you can also establish a TELNET link to the OSM/ESM by clicking the console icon. If you click the support or SIEMENS icon, you automatically open the A&D home page.

4. Now enter the password and confirm by clicking the OK button.


C79000-G8976-C137-08 4-5


Note

If no new passwords have been assigned, the valid password is the default admin

(to use WBM as an administrator, for example with write/read permissions) and

user (to use WBM as a user with read permissions only).

The admin and user passwords can only be modified via the CLI, see 3.5.

If you lose the password, you can reset the OSM/ESM to the original defaults with the button on the front panel, see Section 2.4. The admin or user passwords are then valid again.

As a reaction to the login, a web applet is loaded from the OSM/ESM. The following WBM startup window is displayed (see Figure 4-3).

Device status

User Interface of Web-Based Management

The dialogs of the OSM/ESM WBM are made up of a device status field, a menu tree, and a data window.

Menu tree

Data window

C79000-G8976-C137-08 4-7


Device Status Field

The displays in the device status field correspond to the LEDs of the OSM/ESM, see /1/. The swapping over of the meaning of the port LEDs and the power LEDs

(with the display button) is not implemented. Instead of this, the transmission rate, duplicity and the fault mask are represented by a separate row of LED symbols.

The signaling is identical to the LED signaling of the OSM/ESM, see /1/. The device status field is displayed and updated in every menu so that you have an overview of the current status of the OSM/ESM at all times.

The device status field also shows the OSM/ESM type (for example, OSM ITP53) and the system name (or the IP address if “sysName Not Set”) of the OSM/ESM.

On the OSM BC08, OSM TP22, and ESM TP40, the states of the digital inputs are also indicated on the right bedside the port LEDs.

Menu Tree

By navigating through the menu tree, you can open the individual windows of the

OSM/ESM WBM in much the same way as when working in the Windows Explorer by clicking the relevant icons.

Data Window

The data window displays the current values and allows you to enter new settings.

Settings that cannot be modified are displayed in gray.

4.8.1

OSM/ESM Fault Mask

Figure 4-12 shows the Fault Mask window.


Figure 4-12 OSM/ESM Fault Mask Window

The fault mask is used to specify which fault states are monitored by the

OSM/ESM and lead to the signaling contact being triggered and the fault LED being lit.

The fault mask can also be set using the buttons on the front panel of the

OSM/ESM, see /1/.

Enable Power Monitoring

This specifies which of the two power supply lines 1 and 2 is monitored. A fault is indicated by the signaling contact when there is no power on one of the monitored lines (line 1 or line 2) or when the voltage is too low (less than 14 V).

Enable Link Status Monitoring

This enables/disables the link monitoring for ports 1 to 4 or 1 to 8. If the monitoring is activated on one of the ports, a fault is signaled (fault LED, signaling contact) when there is no valid link at this port (for example cable not plugged in or connected device turned off).


C79000-G8976-C137-08 4-21


Set New Values

To change the settings in the fault mask, follow the steps outlined below:

1. Click the check box in the fault mask to decide which of the power supplies and ports will be monitored.

2. Then click the Set New Values button.

Note

Fault Mask and RM Mode

Activating the RM mode means that the ring ports (ports 7, 8) are entered in the fault mask. Deactivating the RM mode alone, does not mean that the ring ports are taken out of the fault mask. To do this, the fault mask must be reconfigured.

4-22


C79000-G8976-C137-08


4.8.2

OSM/ESM Standby Mask

Clicking the Standby Mask menu opens the window shown in Figure 4-13 .

Figure 4-13 OSM/ESM Standby Mask Window

With network management, you can define several standby ports when rings are coupled redundantly, see Section 2.16. With a redundant configuration, you can then interconnect several rings or networks redundantly.

In the standby mask, you specify which ports of the OSM/ESM will operate as standby ports when working in the standby mode.

If there is no fault, only the standby ports of the standby master are active and handle the data exchange. If the standby master or the link of one of the standby ports of the master fails, all standby ports of the master are disabled and the standby ports of the slave activated so that a functioning configuration is established.

Please remember that the same ports on the standby master and on the standby slave must be configured as the standby ports. If an optical port of the OSM ITP62 is used in the extended redundant configuration, it must have a hardware version of at least 2.


C79000-G8976-C137-08 4-23


To modify the assignments in the standby mask, follow the steps outlined below:

1. Select the ports to be monitored by clicking the relevant check boxes in the mask.

C79000-G8976-C137-08


4.8.3

OSM/ESM Counters

Figure 4-14 shows the OSM/ESM Counters window. Using the OSM/ESM counters, you can monitor whether and how often problems occurred during operation (for example how often the signaling contact responded). The fault counters are cleared when the power supply to the OSM/ESM is turned off or when you click the Reset Counters button in the window.

Figure 4-14 OSM/ESM Counters Window

No. of Signaled Faults

This indicates how often the signaling contact of the OSM/ESM responded.

No. of Changes to RM Active State

(Only in the redundancy manager mode) This indicates how often the OSM/ESM acting as the redundancy manager changed to the active state. This state is adopted only when the RM has detected a break on the line of OSMs/ESMs connected to the ring ports (port 7 and 8 of 8-port devices, port 3 and 4 of 4-port devices). If the RM mode is disabled (DIP switch RM “off”), no value is displayed.


C79000-G8976-C137-08 4-25


Maximum Delay of RM Test Packets (ms)

This display is only active in the redundancy manager mode (RM “on”). In the redundancy manager mode, the OSM/ESM sends test packets on the line of

OSMs/ESMs attached to ports 7 and 8 and measures the round-trip time of the test packets. The maximum delay of the test packets that occurs is displayed. This value should not exceed 50 ms.

No. of Changes to Standby Active State

This counter is only active when the standby mode was activated with the DIP switch on the OSM/ESM (”Stby on”). It indicates how often the OSM/ESM acting as the standby slave switched to the active mode in the redundant configuration.

(This can be caused by failure of the standby master or because there was no longer a valid link at a standby port of the standby master.)

Switch Features

Figure 4-22 shows the Switch window.

Figure 4-22 Switch Features Window

Mirroring

Mirroring means that the data exchange at a port (mirrored port) of this OSM/ESM can be “reflected” to another port (monitor port). If a protocol analyzer is connected to the monitor port, it can be used to record the data exchange at the mirrored port without interrupting the connection at the mirrored port. To use this function, there must be a free port on the OSM/ESM that can be used as the monitor port.

4-36


C79000-G8976-C137-08


Aging

OSMs/ESMs automatically learn the source addresses of the nodes connected to them. This information is used on the OSM/ESM to pass packets to the intended recipients. This reduces the network load for the other nodes.

If the OSM/ESM does not receive a packet with a source address that matches a learned address within the aging time, it deletes the address from the database.

This prevents packets being passed on incorrectly if, for example, a DTE is connected to a different OSM/ESM port. The default for the aging time is 40 seconds. By setting aging to disabled, addresses are no longer automatically deleted.

Flow Control

Using flow control, the OSM/ESM can slow down the reception of further packets at the ports if the network is overloaded. Flow control must be activated separately for the individual ports in the port mask. If the Flow Control Enable check box is deactivated in the Switch window, the flow control mechanism is deactivated for all ports regardless of the settings made in the port masks.

Set New Value

Follow the steps outlined below to change settings in the Switch window:

1. First, enable the check box for the individual parameters by clicking them or select the mirrored port or monitor port from the list boxes.

2. Then click the Set New Values button to enter the values.

C79000-G8976-C137-08 5-1

SNMP and RMON

5.1

SNMP

With SNMP (Simple Network Management Protocol), a network management station can configure and monitor SNMP-compliant nodes such as the OSM/ESM

(from firmware Version 2.0 and higher). To make this possible, a management agent is installed in the DTE with which the management station exchanges data using SNMP Get and Set requests. The OSMs/ESMs support SNMP V1.

The data that can be managed are in a database on the OSM/ESM (DTE) known as the MIB (Management Information Base) that can be accessed by the management station (or the applet of the OSM/ESM Web-Based Management) using the agent.

There are standardized MIBs defined in RFCs and private MIBs containing product-specific extensions that are not covered in standard MIBs.

The OSMs/ESMs with network management support the following MIBs:

RFC 1213: MIB II

RFC 2233: Interface MIB

RFC 1286, RFC1493: Bridge MIB

RFC 1757: RMON MIB

OSM/ESM private MIB

The private MIB of the OSM/ESM is on the supplied CD. The private MIB file can also be downloaded from an OSM/ESM directly with a Web browser at http://<IP address of the OSM/ESM>/snOSM.mib. Please note the capitalization of snOSM.mib! In the Internet Explorer, click on View and save the MIB as source text. The description of the MIB objects of the private MIB is included in the MIB and can be read directly with a MIB compiler (for example the network management station) or with a text editor.

The read-only community string (SNMP password for read access) is set to

public, the read-write community string (SNMP password for read and write access) is set to private and can be changed using SNMP or the Agent menu in the CLI, see Section 3.5.

5-2


C79000-G8976-C137-08

SNMP and RMON

5.2

RMON

A RMON-compliant device (RMON = Remote MONitoring) allows you to collect special diagnostic data on the device, to prepare this data and to read it out via

SNMP at a network management station that supports RMON. This diagnostic data such as port-related load allows you to detect network problems early and to eliminate them. These are stored on the OSM/ESM in the RMON MIB.

RMON functionality is defined in RFC 1757 and is divided into groups. All

OSMs/ESMs with the exception of OSM TP22 and ESM TP40 support the four

RMON groups Statistics, History, Alarm and Event.

The following table summarizes the options provided by these four groups.

Table 5-1 RMON Groups and Their Functionality

RMON Group

Statistics

Description

This provides statistical information for each OSM/ESM port such as packet rate, packet distribution, number of broadcast, multicast, unicast packets, number of received bad packets sorted according to error types.

History

Alarm

This RMON group allows specific statistical information on the

OSM/ESM to be selected, queried at periodic intervals and stored.

You can read out this information at a management station later and display it in chronological order (for example the chronological order of the error rate).

The alarm group also queries certain statistical values periodically and compares them with limit values configured previously on the

OSM/ESM by the management station. If a limit value is violated, an alarm is generated and a trap is issued. The alarm group is only possible when the event group is supported.

Event The event group controls generation of traps when RMON alarms occur.

C79000-G8976-C137-08 6-1

Upgrading/Downloading Software

6.1

General Introduction

The firmware of the OSM/ESM can be loaded in two different ways:

S

Over the serial port of the OSM/ESM

S

From a TFTP server, see also Section 6.3.

You will find information on firmware updates for OSM/ESM on the Web at http://www.ad.siemens.de/csi/net .

This chapter describes the downloading of the OSM/ESM firmware in detail.

Note

After you have downloaded the firmware, the new firmware is stored in non-volatile memory on the OSM/ESM and the original firmware is erased. If the power supply to the OSM/ESM is interrupted during the download, the loaded firmware may be incomplete and not executable. You can recognize this by the fault LED being lit permanently and when the display LEDs do not switch over when you press the

OSM/ESM button (after the OSM/ESM has started up). In this case, the firmware must be downloaded again via the serial port, see Section 6.2. It is then no longer possible to download the firmware from a TFTP server.

6-2


C79000-G8976-C137-08


6.2

Downloading the Firmware via the Serial Port

To download the firmware via a serial port of the OSM/ESM, follow the steps outlined below:

1. Connect a PC with the Hyperterminal program as described in Appendix B and start Hyperterminal.

2. Reset the OSM/ESM by pressing the Select/Set button during operation (if necessary several times briefly) until the display LEDs display the port status

(all display LEDs off). Then press the Select/Set button for at least 6 seconds.

After approximately 3 seconds, the display LEDs start to flash, after a further 2 seconds the reset is executed (all LEDs go on briefly and then off again).

The following message then appears in the terminal window of Hyperterminal:

Figure 6-1

3. Press the ”Select/Set” button again briefly

4. The following prompt then appears:

Do you really want to update your firmware? Y/N

Confirm with Y (Yes).


C79000-G8976-C137-08 6-3


The following message is then displayed in the terminal window:

Figure 6-2

5. Now select the function Transfer > Send File function in the Hyperterminal window.

6. In the next dialog window, enter the file to be downloaded and select ”Xmodem” or “1K Xmodem” as the protocol. Start the transfer of the firmware with the

”Send” button.

6-4

Figure 6-3


C79000-G8976-C137-08


The following dialog box then appears displaying the progress of the download.

Figure 6-4

Start the download by pressing the ”Set/Select” button again.

Downloading can take up to 10 minutes. After you have downloaded the firmware successfully, the device is automatically started with the new firmware. Please note the version of the new firmware on a label on the side labeling panel of the

OSM/ESM.

Note

During the download, do not interrupt the connection between the PC and

OSM/ESM and do not turn off the power supply to the OSM/ESM.

If the download is interrupted by a problem on a signal line, the device will start up with the old firmware the next time it restarts. The firmware download must then be repeated.

If the firmware could not be downloaded completely to the OSM due to a power failure, the message ”Firmware in flash is faulty” appears after the device starts up. This means that the firmware must be downloaded again.


C79000-G8976-C137-08 6-5


6.3

Downloading Firmware from an TFTP Server

To download firmware from a TFTP server, the server must be accessible to the

OSM/ESM, see Figure 6 - 1.

OSM ITP 62

TFTP server

Network

Figure 6-5 Downloading Firmware from a TFTP Server

Requirements

The following settings must also be made on the OSM/ESM, see Section 3.5 :

S

The IP address, subnet mask and possibly also the gateway address must be configured on the OSM/ESM using the CLI, see Section 3.5.

S A TFTP server with an installed IETF TFTP program (RFC 1350) must exist in the network and must be accessible to the OSM/ESM. (This program is not provided by SIEMENS. It is however included with various systems and

TCP/IP packages. The server can be a DOS, UNIX or Windows station.)

6-6


C79000-G8976-C137-08


Note

Copy the program file to the TFTP server so that the TFTP client (OSM/ESM) has access for the download.

Downloading

Follow the steps outlined below to download the firmware:

1. Make sure that all components (OSM/ESM, TFTP server, etc.) are started up and functioning correctly.

2. Start a WBM (or CLI) session. (For more detailed information, refer to Chapter

3 or 4).

3. Make the following entries in the System menu or the in the System Save &

Load window:

S

Enter the TFTP Server IP Address (the IP address of the TFTP server on which the new OSM/ESM firmware is located)

S Enter the Firmware File Name (name and if applicable path of the file on the TFTP server containing the new OSM/ESM firmware)

S Select the Start Download command.

Before the new firmware takes effect, you must restart the OSM/ESM.

Note

In the RM mode, the ring monitoring is deactivated during the TFTP download; in other words the redundancy manager cannot react to breaks in the ring during the download.

No.

Problem

LED L1 and L2 OFF

2 LED Fault ON

Possible Cause

No power supply

Remedy

Check the 24 V power supply.

OSM/ESM startup after turning on the power supply.

The fault mask does not match up with the current status of the power supplies or the port assignment.

None

Fault LED goes off following startup if there is no further problem.

Check the power supplies and port assignment, if necessary update the fault mask, see /1/.

In the RM mode also:

Connection to a ring port interrupted.

Check the connections to the ring ports

(port 3 and 4 on 4-port devices and port 7 and 8 on 8-port devices).

Turn off one RM.

Two RMs in ring simultaneously.

Redundant coupling, also:

Short-circuited or break on

ITP XP standard cable 9/9.

Check the connecting cable between the standby-sync ports of the two

OSMs/ESMs.

Both OSMs/ESMs of the redundant ring coupling are set as master or both as slave.

Link down on a standby port (only when standby cable plugged in).

Switch one of the devices to the master mode (Stby off), the other device to the slave mode (Stby on).

Check the connection to the standby ports.

5

Port Status LED OFF, although a DTE is connected to the port.

10/100 Mbps port performance low.

No connection via the serial port of the

OSM/ESM to the connected PC.

Possible Cause

The firmware was not downloaded completely

(power failure when saving the new firmware) or the

OSM/ESM self test detected a fault.

Problem on the port, the

DTE or the transmission line.

The partner port is not autonegotiating and is operating in the full duplex mode.

Cable function, incorrectly set

Hyperterminal program on the PC, incompatible transmission rate.

Remedy

You can recognize this state after the

OSM/ESM has started up because the fault LED is lit permanently and the display LEDs on the front panel of the

OSM/ESM do not switch over when you press the button.

Download the firmware again if this problem occurred during downloading of the firmware, see Section 6 and restart the OSM/ESM.

If you have not downloaded firmware, restart the OSM/ESM. If the problem persists, the OSM/ESM self test has detected a problem that it cannot eliminate.

Send in the module to your SIEMENS service center for repair.

Faults detected by the self test are logged if you connect a PC with the

Hyperterminal program to the serial port of the OSM/ESM, see Appendix B, and run a cold restart on the OSM/ESM (power off/power on).

Connect the station briefly to a different

OSM/ESM port and check whether the problem persists.

If yes, check the transmission line to the

DTE and check whether the DTE is turned on. If you are using optical cables, clean the connectors.

Using Web-Based Management or the

CLI set the OSM/ESM port to the full duplex mode (autonegotiation disabled).

Check the cable.

Check the settings in the Hyperterminal program.

Check the transmission rate (default 115

Kbauds).

Autocrossover

Capability of automatically crossing over the send and receive signals at twisted - pair ports (automatic switchover between MDI and MDI - X pinning at a port). When, for example, connecting network components, you no longer need crossover cables.

The autocrossover function is available only when autonegotiation is activated.

Autonegotiation

In the autonegotiation mode, an electrical OSM/ESM port sets itself automatically to the transmission rate (10/100 Mbps) of the connected partner device. If the partner device also supports autonegotiation, the devices further negotiate whether they will exchange data in the half-duplex or full-duplex mode and full-duplex flow control see Section 2.12.

FDB table

The FDB table contains node addresses (MAC addresses) and the port of the

OSM/ESM over which the node address is obtainable.

Aging

Aging means that a learned entry in the FBD table is cleared when no packet with a source address corresponding to the entry is received within the aging time. The OSM/ESM assumes that this node no longer exists.

Back pressure

Flow control for ports operating in the half duplex mode. With this type of flow control, the OSM/ESM reduces the packet rate received at a port if there is overload in the network by generating additional collisions.

BOOTP

The Bootstrap protocol is used by the OSM/ESM to download the IP address, subnet mask and address of the default gateway automatically from a BOOTP server. It is also possible to send the name of a file containing the firmware on the TFTP server.


C79000-G8976-C137-08 Glossary - 1

Glossary

Boot software

The boot software is software integrated on the OSM/ESM that is required to download the OSM/ESM firmware. The boot software cannot be reloaded.

Boot version

Version of the boot software.

Broadcast address

Packets with a broadcast address can be read by all nodes in the LAN

(destination address FF:FF:FF:FF:FF:FF).

CLI

Command line interface (see Command interpreter).

Collision

A collision occurs when two DTEs attempt to send at the same time. The collision is handled according to the procedures defined in IEEE 802.3.

Command interpreter

The command interpreter (CLI) of the OSM/ESM interprets the terminal entries and executes the corresponding commands.

CRC

Cyclic Redundancy Check - This is used in data transfer protocols to be able to detect transmission errors (CRC errors) in received packets.

Default

Factory default settings on the OSM/ESM.

Default gateway

The default gateway passes on all packets that are not addressed to stations in the same LAN (subnet).

DNS server

Every computer attached to the Internet has its own unique IP address. So that

LAN/Internet users do not need to learn the numbers to be able to access a particular computer in the network, many IP addresses are assigned alphanumeric names that are managed by DNS servers.

ESM

SIMATIC NET Industrial Ethernet Electrical Switch Module (has only electrical ports).

Event log table

A table in which certain events detected by the OSM/ESM are stored in non-volatile memory for diagnostic purposes. The log table of the RMON MIB is stored under events and is therefore a dynamic part of the MIB.

Fault mask

The fault mask is used with the OSM/ESM to mask out certain fault events.

Events that are not masked cause the signaling contact to respond and are displayed by the fault LED.

Filtering database (FDB)

See FDB table

Firmware

Module software, in this case software running on the OSM/ESM.

Firmware version

Version of the OSM/ESM firmware

Flow control

A function on the OSM/ESM with which the number of packets received at the

OSM/ESM can be reduced in case of overload to reduce the risk of packet loss.

Full duplex mode

An OSM/ESM port operating in the full duplex mode can receive and send data at the same time.

Full duplex flow control

The full duplex flow control of the OSM/ESM operates in compliance with the

IEEE 802.3x standard. If there is overload, the OSM/ESM generates pause packets that stop or re-enable the sending of new packets by the connected partner device. The partner device must support full duplex flow control.

Half duplex

An OSM/ESM port operating in the half duplex mode cannot receive and send data at the same time. Data can only be received and sent alternately.

Glossary - 3

Glossary

Half duplex flow control see Back pressure

HTML

HTML is the abbreviation for Hypertext Markup Language. Using this language it is possible to publish documents in a uniform language on the Web. The main feature of this language is the ability to specify connections to other HTML documents known as URLs.

IP address

An IP address consists of a numeric code made up of four numbers from 0 to

255 (for example 192.168.0.55). This is the numeric address of a specific computer in the network/Internet.

Jabbers

Packets with an invalid CRC and a length greater than 1536 bytes.

Java

Programming language developed by Sun.

Java applet

The name for a Java subroutine. On the OSM/ESM, there is a Java applet in the

Web site of the OSM/ESM that updates the device status shown on the Web site after startup.

Learning

The OSM/ESM automatically learns the MAC addresses and port numbers of the nodes connected to it and stores the information in the FDB table.

Link status

The valid link from an OSM/ESM port to the port of a partner device is monitored by link test pulses. A valid link is indicated on the OSM/ESM, for example by the port status LED being lit (permanent green light).

MAC address

6-byte node address of an Ethernet node.

MIB

Management Information Base. In network management, the database (tree structure) in which all objects and variables that can be managed are entered.

1536 bytes.

Packet size

Length of a packet from the destination address to the CRC field inclusive.

Partition mode

If more than 60 collisions occur during transmission, the OSM/ESM changes to the Partition mode. It waits for the first valid package before it returns to the normal transmission mode. In the Partition mode, it continues to send but no longer receives (partitioned).

Power line 1/2

Power supply line 1/2 of the OSM/ESM.

Redundancy manager (RM)

The OSM/ESM operating as the redundancy manager monitors the line of

OSMs/ESMs attached to it. If there is a break on the line, it switches through and therefore recreates a functioning bus configuration.

Restart

The OSM/ESM can be restarted by the management system (Web Based, CLI,

SNMP).

RM mode

This indicates whether or not an OSM/ESM is operating in the redundancy manager mode (RM on).

RM status

Indicates whether an OSM/ESM operating as the redundancy manager has switched the bus connection through (RM active) or not (RM passive).

Remote MONitoring (RMON)

The RMON agent of the OSM/ESM collects data, for example, on network load that can be queried by a network management station. The OSM/ESM supports the RMON groups: Statistics, History, Alarm, Event.

RFC

Request for Comment - Standardization document of the Research and

Development group of the Internet, for example for defining protocols, procedures and services.
