3 NMS FUNDAMENTALS

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

This chapter gives basic knowledge about NMS in general and SATEL NMS in particular.

3.1 General NMS concepts

NMS stands for Network Management System. Network management is typically defined as follows:

Network management is the execution of the set of functions required for controlling, planning, allocating, deploying, coordinating, and monitoring the resources of a network.

Network management can be further divided into five conceptual areas (The ISO Network

Management Model): o Performance management o Configuration management o Accounting management o Fault management o Security management

Of these areas, Security and Accounting management are used to control user accounts of the managed devices, which is irrelevant in the case of SATELLINE radio modems. The other three areas, however are relevant to radio modems, and are discussed below.

3.1.1 Performance management

The goal of performance management is to measure network performance and make available settings and controls so that performance can be maintained at an acceptable level.

Performance management involves three main steps. o Performance data is gathered. o Data is analyzed to determine baseline (normal) operation levels. o Appropriate performance thresholds are determined for each variable so that exceeding these thresholds indicates a problem worthy of attention.

SATEL NMS supports performance management by monitoring the operation variables of radio modems, such as signal strength (RSSI), voltage and temperature and allowing the user to define alarm thresholds for each variable.

3.1.2 Configuration management

The goal of configuration management is to monitor network and system configuration information so that the effects on network operation of various versions of hardware and

7

SATEL NMS PC Version 2.0.18

User Manual Version 2.5 software elements can be tracked and managed. Each network device has a variety of version information, such as hardware or software version numbers, associated with it.

Configuration management stores this information for easy access. When a problem occurs, the stored information can be searched for clues that may help solve the problem.

The above definition of configuration management has been originally created in an internetworking environment. In a radio modem network, the version numbers of hardware and software can be tracked, and SATEL NMS makes these available. However SATEL NMS also allows changes to made to the settings of the managed devices’ (ie. the radio modems’) settings, which is a task usually delegated to other protocols and methods in the IP world. This feature is called Remote Configuration in SATEL NMS.

3.1.3 Fault management

The goal of fault management is to detect, log, notify users of and (to the extent possible) automatically fix network problems to keep the network running effectively. Fault management involves first determining symptoms and isolating the problem. Then the problem is fixed and the solution is tested on all important subsystems. Finally, the detection and resolution of the problem is recorded.

SATEL NMS provides the basic tools to detect problems and make changes to the network settings from a centralized location, thus simplifying the fault management process of your organization.

3.2 SATEL NMS

SATEL NMS is a comprehensive system for managing SATEL radio modem networks. It includes many software modules and interfaces, running on several platforms.

3.2.1 Features

The main features of SATEL NMS are: o Non-intrusive operation o Remote configuration o Monitoring of network operating parameters o Network design tool

8

3.2.2 Components

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

SATEL NMS consists of a set of interfaces and features offered by certain SATEL radio modem models, including SATELLAR RU, SATELLINE-3AS(d) NMS, SATELLINE-3AS(d) Epic (C) NMS and

SATELLINE-3AS(d) VHF. Using SATEL NMS it is possible to monitor the deployed radio modem network for certain diagnostic parameters and, if necessary, make changes to the modems’ settings online.

The NMS Solution provided by SATEL consists of the radio modems, which support the NMS

Protocol, and the SATEL NMS PC software package, which provides setup and monitoring functions.

3.2.3 Software

The SATEL NMS PC software package contains four Windows applications: SATEL NMS PC,

SATEL NMS PC Monitoring, SATEL Serial Server and Packet Filter Editor.

SATEL NMS PC is used to design the modem network and upload the initial settings to the modems. After deployment, the software can be used to make changes to the settings remotely by radio connection. Also routine maintenance tasks such as replacing or adding a modem to the network, running communication tests etc. are possible using the software.

SATEL NMS PC Monitoring is used to monitor a deployed radio modem network while it is in operation. It provides logging of network parameters and events displays trend graphs and can react to events by sending alarms and running external commands.

SATEL Serial Server provides the other applications multiplexed access to the serial ports of the computer.

Packet Filter Editor is used to define packet filters needed for custom data protocol support.

3.2.4 NMS Protocol

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

The basic method of controlling the SATEL NMS features is through a modem’s diagnostics port, which is one of its serial ports set to operate in the diagnostic (NMS) mode. The NMS port accepts binary NMS commands. This is called the NMS Protocol.

Since the NMS Protocol is a binary protocol, it is not designed for human eyes. Another protocol, called the SATEL Serial Server Command Protocol (S3CP) is an ASCII protocol, and is suited for interactive command line operation as well as software controlled operations.

However, the modems currently in production do not directly support S3CP. Instead SATEL Serial

Server (part of the SATEL NMS PC installation), which can translate S3CP to the NMS Protocol and back.

The above protocols allow access to all the diagnostic parameters of the modems in the radio network. The RAM memory of the modems being scarce, the modems do not generally store large log files themselves. Instead, diagnostics are polled from the radio modems at regular intervals and stored in a central location, usually a Windows PC running SATEL NMS PC

Monitoring.

3.2.4.1 NMS ID

NMSID (or NMS ID) is the identifier of a setting, diagnostic value or command that can be sent to or received from a modem. Every possible setting etc. has its own identifier. For example, the

NMSID of transmitted power of the radio in SATELLINE 3AS(d) NMS is 1.267.

The NMSID consists of two numbers separated by a period character. The first number is the access level (level 1 settings are user settings). The second number is the actual identifier.

The NMSIDs supported by a modem are listed in the user manual of the modem. You can also retrieve the list from the modem using SATEL NMS PC.

3.2.4.2 Message sending modes (ONLINE and OFFLINE)

SATEL NMS can send messages in one of two modes.

If the mode is OFFLINE the packet will be sent immediately to the radio network. If there is already a packet, such as a user data packet in the modem network, and the modem network contains long repeater chains, the new packet may collide with the data packet. This is referred to as the Offline operation mode, because it is best used when the user system is offline and no user data is being transmitted, but NMS messages are.

If the mode is ONLINE the packet will be placed in the master modem’s outgoing NMS message buffer and wait for a user data packet to be sent to the same address as the new NMS

packet. When such a user packet is sent, the NMS frame is attached and sent inside the same transmission, thus avoiding collisions. This is known as the Online mode, as it can only be used when the user system is Online. If there is no user data traffic, NMS frames will not be sent at all

in this mode! This mode depends on the user system to poll each modem in turn. If a modem is not contacted by the user protocol, NMS packets are not able to reach the modem either.

10

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

This mode should be used when there is much data traffic to all modems and data packet loss due to NMS versus DATA packet collisions is not acceptable.

3.2.4.3 Message addressing modes (Normal and ANYCAST)

Normally NMS Messages are sent to the recipient by setting the DADDR field of the message.

DADDR must correspond to the Modem Address Setting (NMSID 1.398) of the destination modem. For example if the destination modem’s address setting is 2, the outgoing NMS message must be sent to destination address (DADDR) 2.

In the specific case of ONLINE Monitoring this normal method of delivering messages can result in long delays. Consider a large network consisting of 100 radio modems operating under a single master. Assume the system is a SCADA system and the data protocol is a polling protocol such as IEC 60870, with one RTU per radio modem. If the SCADA master uses about 1 second to query each RTU, the whole polling sequence takes 1-2 minutes.

Now if an NMS Monitoring message is sent to a modem X in the network, it is possible the outgoing message will have to wait in the buffer for up to 2 minutes before being sent. This happens because NMS Monitoring is unable to synchronize its polling sequence with the data polling sequence. This can cause significant delays to Monitoring, with some modems seeming to drop out altogether.

The solution is to use the “Anycast” addressing mode. In this mode, outgoing NMS messages are not sent to any specific address; instead they go to whichever address the next data packet is going to. The NMS response message will have address information, so the original sender

(usually NMS PC Monitoring) will know which modem the response came from. This way a network of modems can be monitored efficiently.

Anycast is not currently available for SATELLAR RU modems.

4.3 Connecting the modems

This user guide only addresses connections needed for the NMS system. Mounting the modems physically, connecting antennas and power supplies are explained in the modem user manual.

4.3.1 Serial ports and functions

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

There are two serial ports on each SATELLINE-3AS(d) NMS, SATELLINE-3AS(d) Epic (C) NMS or

SATELLINE-3AS(d) VHF modem, Serial Port 1 and Serial Port 2. Each of these ports has three possible functions, one of which can be active at a time. o DATA, used for user data transfer o NMS, used for NMS protocol o OFF

Note that only one of the ports can be a DATA port and one can be an NMS port at the same time, so for example having both ports in NMS mode at the same time is not possible.

The NARS-1F cable allows access to serial port 1. However, to access both port 1 and 2 at the same time, a two-port serial cable (for example CRS-NMS) is needed. This cable has one 15-pin connector (connected to the modem) and two 9-pin connectors, which are labeled ‘1’ and ‘2’, corresponding to port 1 and port 2 of the modem. By default the connector labeled ‘2’ is used for NMS.

See the modem manual for information on how to change the function of the ports.

SATELLAR RU modems have one D9 connector. There are two possible hardware variants, with either RS-232 or RS-485 support. The D9 can support two serial ports if the hardware is RS-

232. The RS-485 variant cannot be used as a Master Modem if simultaneous DATA and NMS functionality is needed (this is usually the case). A two-port serial cable for SATELLAR RU RS-232

D9 is available from SATEL. SATELLAR RU can also be set to accept NMS commands on the normal D9 serial port by using the function button, as explained in the SATELLAR user manual.

This is useful for initial setup using SATEL NMS PC.

4.3.2 Connections during network setup

During initial network setup, SATEL NMS PC needs a NMS PROTOCOL connection to all modems to synchronize their settings.

There are two useful ways to connect the modems during initial network setup:

1. Full operation connection

2. Programming mode setup connection (or SATELLAR RU function button mode 2)

See Table 1: NMS Port Connection methods for details.

*) Programming mode is usually used with terminal emulation software (such as SATELLINE SaTerm) to access the Terminal Setup menu of the modem. Instead of terminal emulator software, SATEL NMS PC may be connected to the modem, as the modem will respond to NMS protocol messages while in programming mode.

In this case the modem can only be configured, radio messages cannot be sent while the modem is in programming mode.

4.3.2.1 Connection procedure

This procedure must be followed when swapping modems connected to the PC.

1. Power modem off

2. Disconnect previous modem

3. Connect new modem

4. Power modem on

4.3.3 Connections in a deployed system

One of the modems in a deployed system is the Master Modem of the system. The other modems are substations (including repeaters).

The Master Modem is special since SATEL NMS PC software connects to the rest of the modems through it, using the radio channel. This is called remote or Over-The-Air (OTA) operation.

One serial port (typically port 1) is configured as the DATA port and the other as the NMS port, which is connected to the PC. SATEL NMS PC will connect to this serial port to send and receive

NMS PROTOCOL messages from the master modem and all the substations.

A substation modem in a deployed network only needs a serial connection to the data terminal equipment, since all NMS commands are sent and received through the radio (OTA). (See

Figure 4). The NMS port is not used in these modems, only the DATA port needs to be

connected to the user equipment.

User Manual Version 2.5

Figure 4: Serial connections in a deployed NMS network

4.3.4 Other connection types

In some cases the port configuration may need to be changed so that port 1 is used for NMS and port 2 for DATA. One such case is if the data port is in RS-485 mode. RS-485 is only supported on port 2 of SATELLINE-3AS(d) NMS, therefore data must go on port 2 and NMS on port 1.

When a two-port (CRS_NMS) cable is not available, a regular cable (e.g. NARS-1F) may be used to demonstrate NMS features by setting port 1 as the NMS port on the Master Modem.

This configuration is only usable for NMS PC demonstration purposes. User data cannot be transferred in this configuration.

4.3.5 Connection checklist

To establish a connection between SATEL NMS PC and a modem, please follow the checklist

below. Also see Table 1.

1) Make sure the modem has power

2) Make sure that the modem is in the appropriate operating mode. a. Programming mode if you wish to change the settings of the local modem only. b. Normal mode if you wish to also use the remote control features

17

SATEL NMS PC Version 2.0.18

User Manual Version 2.5 c. Note that if using the CRS-NMS-01 cable, there is no programming mode switch and the Normal mode is automatically on.

3) Identify the port which has been configured as the NMS port of the modem. If the modem is in programming mode, port 1 is used. In Normal mode, either port 1 or port 2 may be configured as the NMS port. If you are unsure, see the modem’s setup screen or you can first connect the modem in programming mode and change the port setting before going back to normal mode.

4) Connect the modem’s NMS port to any free serial COM port of the computer

5) Start SATEL NMS PC a. Click the “New Network” button

6) The PC’s serial port needs to be opened. Click the Connect button in SATEL NMS PC

Setup. The connect window appears. a. Click Detect available COM ports. SATEL Serial Server is started automatically.

A list of serial ports in the machine then appears in SATEL NMS PC.

- If you have firewall software installed you might be asked to allow outgoing connections from SATEL NMS PC, or to allow SATEL Serial

Server to work as a server. SATEL NMS PC does not usually connect to the Internet, but this needs to be allowed because Serial server and the other programs communicate with each other using the IP protocol in the local machine. b. Select the correct port from the list and click Test connection. A NMS message is sent to the port to see if a modem answers. If “No response” is received, try another port or check your cables and port settings. By default, NMS modems use

9600 bps, 8N1 as the port settings. SATELLAR RU uses 115200 bps, 8N1. c. Once the modem responds, click OK to proceed.

7) SATEL NMS PC Setup will ask what to do with the found modem. If you wish to create a new network using the modem, click Add and start following the To-do list. See 5.4 for more information. Otherwise you may just click Add and go the Modem View if you wish to examine and/or change the individual modem’s settings.

4.3.6 TCP/IP Connections

Instead of a serial port connection, SATEL NMS PC Monitoring and Setup are able to use a

TCP/IP (Internet Protocol) connection to the master radio modem. This is useful in case a serial cable cannot be used for some reason, such as the distance between the PC and the master modem.

In this case additional hardware is usually needed to act as a bridge between the internet and the master modem. Usually a serial port server is used.

Note that most port server hardware available come with virtual serial port drivers which can be installed on the PC. You may wish to use a virtual COM port instead of an IP port connection in

18

SATEL NMS PC Version 2.0.18

User Manual Version 2.5 this case. If you decide to use virtual COM ports, the connections from SATEL NMS PC programs are defined as usual with normal COM ports, see above in this chapter.

SATELLAR CU can also be used to as a TCP/IP access point for NMS messages. In this case, normal TCP/IP radio traffic is not available, the network is configured using SATEL NMS PC and only the Master modem needs a CU (SATELLAR 2DS) The role of the CU is simply to route NMS messages to the SATELLAR RU network.

5 DESIGNING RADIO SYSTEMS AND NETWORKS

You should already have a general design ready for your network when starting to use SATEL

NMS PC. SATEL NMS PC can be used to automatically calculate the routing and other settings of radio networks, but it cannot calculate link budgets or performance requirements of data traffic.

5.1 General notes about networks in SATEL NMS PC

In SATEL NMS PC a system may contain one or more networks. The distinction between systems and networks has been adopted to allow monitoring of multiple networks at the same time.

Each network is defined by having its own frequency, Network ID and master modem. Modems in different networks do not communicate with each other (Except in very rare cases).

A system is a collection of networks. SATEL NMS PC saves systems into .saxd files and SATEL

NMS PC Monitoring may be used to monitor all networks of a full system at the same time.

5.2 Routing modes

The Routing mode setting controls how data is transmitted in the radio network. Currently the

SATELLINE 3AS NMS modem family, SATELLAR RU and SATEL NMS PC support a routing mode called “NMS Routing” (aka Source Routing).

5.2.1 NMS Routing

This mode is suitable when the DATA protocol is a polling protocol and all radio traffic is originated from and controlled by the data master station. Thus substations (RTUs) are not allowed to start sending data without being asked first. This rule is not enforced by the radio modems; it is entirely up to the data system. Breaking the rule could cause collisions on the radio channel.

SATEL NMS supports this type of routing mode using a set of features including routing tables, packet filters and terminal addresses.

5.2.1.1 Routing tables

Routing tables are stored at the master modem. They are generated by SATEL NMS PC during the “Calculate Routes” operation and stored during the “Synchronize” operation.

Routing tables contain information in a row format. Each row defines the chain of modems through which a certain RTU may be reached. The modems are identified by Modem Address.

The RTU is identified by a Terminal Address. The modem address chain is sent along within the radio frame so each modem (repeater) along the way knows where to send it next. When a response is sent by the RTU, the chain is reversed and the process is repeated in inverse.

20

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

This behaviour means that routing information is only stored in the master modem. Therefore it easy to add modems to and change routes of a network even after deployment.

To generate routing tables, the terminal addresses of RTUs must be given to SATEL NMS PC.

This is done by adding “Terminal Addresses” to each substation radio modem’s settings, one address per connected RTU. SATEL NMS PC uses this information to generate routing tables, which are stored in the master modem.

Note that routing tables are needed for NMS traffic to work, too. This means that even a demo network without any data traffic needs routing tables.

5.2.1.2 Protocols, Packet filters and Terminal addresses

To successfully route a data packet to the correct substation, the master modem must determine the Terminal Address of the packet. This is accomplished using Packet Filters. A Packet Filter is a firmware routine running in the Master modem, which looks at the data packet and finds the address field in the data.

The Packet Filter routine has settings to support different data protocols. Selecting a “Protocol” in SATEL NMS PC affects the Packet Filters settings of the master modem.

Repeater modems do not need to be configured with terminal addresses, but may have them in case RTU’s are used at the repeater stations.

5.3 Essential network information checklist

The following table lists information needed while designing a network.

Item Explanation

General system topology

How many networks will your system consists of? Each Master or Base station you have will become the Master Station of one Network. Each network has exactly one Master Modem.

Network ID A string of 8 characters. Select a unique ID for each network in the system. The modems only accept radio messages sent by modems that have a matching Network ID. This prevents data from neighbouring networks operating on the same frequency from getting mixed up with each other’s traffic. Note that usually neighbouring networks should have different frequencies. Network ID is an additional safety precaution.

Frequency You will usually need to apply for a private frequency from the local authorities. Make a note of this frequency and input it into SATEL NMS

PC.

21

Network protocol

Terminal addresses data

Substation names

Link budget

FEC on or off?

Additional radio settings

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Which data protocol is your network using? MODBUS, IEC 60870, ANSI or SATEL I-Link, for example.

SATEL NMS PC Setup needs to know the protocol, so that correct Packet

Filter settings can be loaded into the master modem. (For NMS demonstration networks without any data traffic, any protocol is fine.)

You’ll need the protocol addresses of all the terminals you plan to connect using the radio modem network and information about which radio modem substation each terminal will connect to.

If you are only using the modems to demonstrate NMS without actual user protocol traffic, terminal addresses still need to be defined so that routing tables are generated. SATEL NMS PC and the Master Station modem depend on the routing tables to send NMS messages to the substation modems.

Each radio modem should be named using a descriptive name; the location where the substation is to be deployed is normally used.

You’ll need a link budget so you can select the correct TX Power settings for the modems. For desktop testing use the lowest TX Power setting possible, and switch to the proper TX Power calculated in the link budget before deploying.

FEC stands for Forward Error Correction. Enabling FEC improves data transmission reliability, at the cost of some of the data transmission capability. Please consult the modem manual for details.

SATELLAR RU has additional radio settings which must be set. Please consult the SATELLAR manual. SATEL NMS PC can be used to set the values of the settings.

5.3.1 Creating a simple Network

6) Re-connect your master modem and click the Detect button in the toolbar to ensure it is connected.

7) Go to the Network info view by clicking the network’s name in the System tree view

8) Using another cable, ensure your other modem has power. Attach antennas to both modems.

9) Test the network by clicking NMS Radio connections under the Tests groupbox. a. Both modems should respond.

10) Now your two modem system is configured and tested! Next steps are a. Add more modems b. Configure Monitoring settings c. Run extensive desktop tests d. Deploy the network

5.3.2 Adding modems to an existing network

Modems may be added by clicking “Add Modem using defaults” in Network design view

(6.7.4). The settings of the new modem are copied from the Default Modem settings (see

below). In addition, SATEL NMS PC Setup will manage the settings so that network-wide settings such as Frequencies and FEC are the same in all modems.

24

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Using the Default Modem settings

Use the Default Modem settings view to ensure that all modems will have the same general settings. Go to the Default Modem view, by clicking on Default modem under

Settings in the system tree view.

You can change the default modem settings to values which should be common to all modems in the network.

Now whenever you create a modem using the Add Modem using defaults command, it will have these settings already selected.

After adding the modem, add a logical radio link to the Master Station, or if a direct link to the master is not possible, nearest repeater.

In the Design view: o Select the modem icon o Right click o Select add link o Click the target modem

5.3.3 Defining Terminal Addresses

For routing to work, each modem must have a terminal address, or several addresses in case there are several user terminals connected to the data port using for example an RS-485 adapter. These correspond to the actual addresses of the user’s protocol. SATEL NMS PC will use the defined terminal addresses to generate the routing tables of the master modem.

Note that, in NMS Routing mode, although the terminal addresses are defined in the Modem

View for each substation modem, the terminal addresses are only saved to the master modem in the form of the routing tables. Therefore changing a terminal address does not necessitate updating of the substation modem settings, only the master modems’ settings.

The Terminal addresses are defined in the Basic Settings tab of Modem View. Select each modem in turn on the tree view under the Modem List item and define their terminal address(es) by clicking on the “Add…” button under the Terminal Addresses heading.

The terminal addresses are defined using the Input Terminal Address window (Figure 5), which

appears when the “Add…” button is clicked.

25

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Figure 5: Input Terminal Address window

The green/yellow/red bar located on top indicates if the address you are typing is legal for the selected protocol filter.

The format of the number you are inputting; Decimal, Hexadecimal or ASCII, depends on the selected protocol. The length of the address depends on the protocol that is in use. The maximum length supported by SATEL NMS is four bytes. If a protocol has a four-byte address, then:

-

In decimal mode, values from 0 to 4294967295 are accepted.

-

In hexadecimal mode, values range from 0 to FFFFFFFF.

-

In ASCII mode from one to four characters are accepted.

In all cases the value is displayed in Hexadecimal format in the Address in packet box . Addr1,

Addr2 etc. refer to the packet filter address bytes. This information can be useful when defining custom protocol filters using Filter Editor.

You must take care to input the address of the equipment that will be actually connected to the modem in question once the network is deployed.

A terminal address may be changed by double-clicking on it in the list in Modem View.

5.3.4 Protocol example: I-LINK Protocol

The SATEL I-LINK protocol is an ASCII protocol, i.e. it uses human-readable characters in the protocol packets. To use SATEL NMS with I-LINK as the DATA protocol, remember to select the

I-LINK protocol in the Main Network View.

The slave address is input in decimal format.

26

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Figure 6: I-Link address switches

The address set using the dipswitches of the I-LINK 100 I/O Converter must be converted to a decimal number. For example if dipswitches “64”, “16” and “1” are selected, the address is

64+16+1 = 81 in decimal format. See the I-LINK manual for details about the address format.

Figure 7: Terminal address input window

For example Address 1 will appear as Addr2=0x30(‘0’) and Addr1=0x31(‘1’), because character ‘0’ equals 30H and character ‘1’ equals 31H in the ASCII character coding system.

5.3.5 Generating Routing Tables

Click the Calculate Routes button in the toolbar or in the To-do list. A message box will appear to inform you what settings were automatically changed. The Routing tables of the Master modem are generated based on the links drawn between modems and on the terminal addresses defined in the Modem View. If you change either of these, click Calculate Routes again.

Routing tables are saved to the master modem when it is synchronized.

27

5.3.6 Transmitting Settings to the Modems

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

All changes to the network so far have only affected the settings within SATEL NMS PC. Now the settings are to be transmitted to the modems. To accomplish this, each modem in turn is connected to the PC and their settings are then uploaded from the PC into the modem.

1) Go to the modem’s Modem settings view

2) Click Synchronize

3) If SATEL NMS PC has not connected to that modem before, it shows the Unknown

modem address dialog (See 6.8.2). In this case, connect your modem and click OK.

4) Wait while the modem is synchronized.

Repeat the above sequence for each modem.

If at any time you are not sure of which modem is connected to SATEL NMS, click the Detect button.

5.3.7 Testing the network

First connect the Master modem to the PC and click Detect. This ensures the Master modem is connected.

For further testing, a Ping test is provided in the Tools menu. Enter number of messages to send and target address. SATEL NMS PC will send RSSI requests to the modem address and measure the time it takes the modem to answer.

There are also other tests in the Tools menu, and SATEL NMS PC Monitoring may also be used to test the network.

6 SATEL NMS PC SETUP

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

This chapter explains how to use SATEL NMS PC Setup. At the beginning of the chapter you will find an overview of the program features and a list of common tasks. Towards the end of the chapter all the commands, views and windows of the program are explained.

6.1 Overview

SATEL NMS PC Setup is a network administrator’s tool, and it allows the user to: o Set up a radio modem network initially o Draw the network using modem icons and link arrows o Automatically determine radio modem settings for each modem of the network o Upload settings to each radio modem individually o Run a series of tests on a radio modem network o Change radio modem settings remotely using the radio connection o Add radio modems into the network o Replace radio modem hardware o Configure monitoring settings for SATEL NMS PC Monitoring o Save and load radio modem system files o Export a device list

6.2 Common tasks

This subchapter lists some common tasks and how to perform them. Refer to later sub-chapters for explanation of the different windows, views, commands etc. of the program.

6.2.1 Creating a new network

Software required: SATEL NMS PC Setup

Setting up a network of SATEL NMS-capable modems using SATEL NMS PC Setup is relatively easy. Broadly speaking, the process consists of the following steps.

1. Acquire at least two radio modems and necessary cabling

2. Install and start SATEL NMS PC Setup

3. Create a new network in SATEL NMS PC Setup

4. Follow the To-do list in the lower left-hand-corner of the program window

29

SATEL NMS PC Version 2.0.18

User Manual Version 2.5 a. The To-do list consists of task buttons which you click in order, and the program then asks you to input certain data and settings related to each task to create your network. b. Finally the system file is saved to disk and the modem settings are synchronized one modem at a time

5. Test your network’s radio connections in your lab

6. Deploy your network

6.2.2 Adding a radio modem substation or repeater to an existing network

Software required: SATEL NMS PC Setup

Go to Design View and click New Modem. Then follow the To-do list to finalize settings. (Add necessary links to/from the new modem. Add a terminal address. Select serial port settings.

Click Calculate Routes. Synchronize the Master and the new modem)

Finally test the new modem before deploying.

6.2.3 Replacing a deployed broken radio modem with a spare

Software required: SATEL NMS PC Setup

You need to have access to the .saxd file for the system which the broken modem is part of.

Load the .saxd file. Then connect the spare modem to your PC and go to the Modem View of the broken radio modem. Click Replace Modem and follow the instructions. Once the spare modem has been synchronized, test it. Finally go to your site to remove the broken modem and install the spare modem.

6.2.4 Setting up a redundant master modem

Software required: SATEL NMS PC Setup

Purpose: Configure settings so that NMS Monitoring is able to cope with a radio modem network where the master station is redundant, i.e. there are two master radio modems, one of which is the primary device, while the other is a backup. Your own system (e.g. SCADA) is responsible for powering up the secondary modem in case the primary modem stops responding for some reason. SATEL NMS PC Monitoring has a connection to both modems and will use whichever is currently powered up to monitor the radio modem network.

What to do: First set up a network with one of the master modems. Then, when everything works, duplicate your network using the Duplicate Network command found in the Network menu and use Replace Modem on the master modem in this new duplicate network, replacing it with the backup hardware. Also go to Network settings view and in the Primary Network selection box, select the original network. Also use different COM port for each. Now

Monitoring can use the backup master if the primary master stops responding, and vice versa.

30

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Note that all the substation radio modems appear in both networks. If there are changes to the substation modems, these changes need to be duplicated in both networks.

Strictly speaking this is not a problem, unless modems are added, removed or replaced. Best course of action is to make all changes in the primary network and then remove the secondary network and duplicate it again as explained above.

Common settings

Network ID Level *

Terminal address length and maximum route count *

Substation modem return routes *

Network ID : The Network ID is a string of 8 characters. It is used by the radios as a sort of password, so only modems with the same Network ID are able to decode each other’s messages. NMS PC sets the Network ID to all modems when changed.

Click Change ID… to choose the ID.

Frequency : This is the frequency of the network. Both TX and RX Frequency settings are affected and will have the same value. Clicking Change frequency… will open a window which assists in selecting a valid frequency, given the capabilities of the modem HW.

Routing : Currently selected Routing mode. Can be changed by clicking on Select

Routing mode. Only shows routing modes supported by the modem model and

NMS PC.

Device Model: Different device models support different features. If a modem hardware has been connected, the model is detected automatically. Otherwise

(when designing a network before having hardware), use Select device model to choose the radio modem family you are planning to use. This way SATEL NMS PC can show the correct features in this and other screens for the desired model.

Network ID Level indicates the version of Network ID encoding. Level 0 is the default. In Modem SATELLINE 3AS NMS models, FW 4.0.13 or later, improved encoding level 1is available. Always use Level 1 if it is available on all modems of the network.

SATELLAR RU does not need this setting, improved mode is automatically on in all versions.

This feature is supported on SATELLINE 3AS NMS family with new Hardware and FW

V4.0.13.34 or later. Up to 200 source routes and modems per network are supported, but maximum terminal address length is limited to 2 bytes (16 bits). To enable, select “16bit (Max 200 routes)” from the selection box. 32bits is the default.

Only the Master modem needs to support this feature for it to work. (Other limitations may also apply)

Return routes is a new feature supported in SATELLINE 3AS NMS radio modem family with FW versions 4.0.13.32 or later. A return route is normally automatically created in a Substation modem’s RAM when it receives a data message from the

47

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Protocol

Master modem. Any responses from the serial port/RTU are sent back to the Master using the return route. If the radio modem resets before the response is sent, it is lost, as the return route is erased from RAM.

The default setting is Do not generate default return routes and it works as explained above. If Generate default return routes is selected, a static return route is created and stored in the Substation modems, therefore allowing responses to be sent to the master even after the substation has reset before a radio message from the master is received. The tradeoff is that whenever network routes are adjusted, substation modems need to be synchronized. Normally only the Master needs to be synchronized when routes change.

Here you can select the protocol your system uses for data transfer. Click Select

Protocol to open a dialog which allows you to select the suitable protocol.

If your protocol does not appear in the list, you can use the Packet Filter editor (see

chapter 9) to create one. Click Launch Filter Editor to access the Packet Filter editor

This area shows the modems and links that have been defined.

You can click on a modem to select it, after which you can perform operations on the selected modem. The operations are accessed through the Menu bar, Toolbar or the Context menu

(right click).

You can create a link or links by first selecting a modem or multiple modems (by dragging a selection box around them), then right-clicking the mouse to bring up the Context-menu. Select Add

Link from the context menu: The link(s) appear and start following the mouse. Click on the modem you want to link to finish link creation. Clicking elsewhere will cancel link creation.

Links point from the Master Modem toward the substations. Any modem which has both incoming and outgoing links becomes a repeater.

Usually link direction is adjusted automatically. Sometimes a link cannot be created, in this case make sure other links point to correct directions, by Reversing them if necessary, and try again.

You can select a link by clicking on the “/” character on it.

Selected links can be reversed and deleted. Use the context menu

(right-click). See also 5.5.6

Routing tables This area can be brought up by selecting Show routing tables. The routing tables shown are the result of the latest Calculate routes operation. Routing tables are not uploaded into the master modem until it is synchronized.

The text [changed] indicates that the routing tables have not been uploaded yet.

You may make changes to the routing table by deleting and creating links. Since routing tables are only stored in the Master

Modem, substations and repeaters are completely unaffected by changes to the links. This makes it easy to try alternate routes if for example link quality is not good enough along some routes.

Explanation

By default all modems are reached by the connection defined in network settings (Connection button in toolbar or in

Network settings view). This means that when the modem is synchronized, it is either directly connected to the port defined in network connection, or the Master is connected to that port and the other modems are reached through the master by radio connection.

If you wish to connect some modems directly to the PC by using a different connection, you can define a custom connection here.

You can change the TX (transmit ) Power of the modem. All choices shown are supported by the modem if a Hardware has been connected.

Signal threshold can also be changed. See modem manual for details.

Warning! If you select a too low power setting for a deployed modem it might stop responding after being synchronized.

This area lists all addresses of user terminals connected to this modem’s data port. This information is needed so that routing tables can be generated.

Use Add to add a terminal address.

Select a terminal address in the list and click Edit or doubleclick it to edit the terminal address.

Select a terminal address and click Remove to remove it.

NOTE: Making changes to terminal addresses require

Calculate routes and synchronizing the Master modem to become effective.

66

SATEL NMS PC Version 2.0.18

User Manual Version 2.5 unreachable after the process completes!

Additional notes about the process:

ï‚· First a connection test will be made, so if a modem is unreachable the process will stop safely. The same applies during the process.

ï‚· NOTE: It is recommended to always change the whole network! If you disable a modem, it will “drop out” of the network until it is either manually changed to the new setting by visiting on-site, or the whole network is changed back to original settings.

ï‚· If you have long repeater chains and disable one repeater in the chain, you should manually disable also the modems behind it, or the process will fail. This will also cause the whole branch to “drop out” of the network.

6.8.3.1 Background

When critical radio settings are changed, radio contact will be lost to farthest modems along the repeater chain until all modems have been changed. Therefore radio settings must be changed starting from the remotest modems and working up the repeater chain towards the master, which will be changed last.

In Figure 30: Example network with repeaters there are six modems. Modems S2 and S3 are

farthest from the master (M), therefore they appear first in the list. See the table below for an example of a modem list for this network.

Modem at index 0 will be changed first, then index 1 and so forth, until the Master modem is changed last. The list is used to order all radio message operations during the process.

67

Broadly speaking, the process consists of the following steps:

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

1. Preparation step a. Generate a list of all modems, ordered from farthest to nearest (in repeater steps) b. Stop DATA traffic c. Test radio connections to all modems d. Determine the NMSIDs and values of all radio settings to be changed e. Calculate automatic radio settings restore timeout value and send it to all modems

2. Transmit settings step a. Send all new settings to all modems in order (see step 1a)

3. Activation step a. Send InitRadio command to all modems in order (see step 1a) b. Test new settings by sending GetVal to all modems in order (see step 1a)

4. Save settings step a. Save new settings to all modems by sending SaveUserSettings command to all modems in order (see step 1a)

5. Finished

6.8.3.2 Error handling

The algorithm has been carefully designed to minimize the risk of errors and the chance of modems dropping out of the network (which would necessitate a visit to the site). For example, the process automatically stops and removes any changes made if any modem suddenly stops responding.

However there is always a risk of something going wrong. Usually the rewards outweigh the risks, because instead of visiting all the sites, you are only forced to visit some of the sites IF something goes wrong, which is unlikely.

6.8.4 Encryption keys window

This window is used to set the network-wide encryption keys used in SATELLAR RU.

It can be opened by clicking Keys… in the Network settings view, Over the air data encryption

Purpose

Select which parameters you wish to monitor (typically all).

ï‚· Voltage is the input voltage of the radio modem

ï‚· Temperature is the highest temperature value measured inside the RF board during transmit

ï‚· Last RSSI is the measured Signal Strength of the incoming message which contains the NMS poll message asking for the RSSI.

ï‚· RSSI is link RSSI measurement in both directions of each link. RSSI values are stored in modems and

NMS Monitoring asks for each value separately.

ï‚· Combined diagnostic values is a single NMSID which contains Last RSSI, Noise Level, Voltage,

Temperature and Transmit power measurement. It is recommended to use this combined ID together with

“RSSI” to get the most effective Monitoring setup possible. In large networks (more than 30 modems),

RSSI should be omitted.

Updates the poll list. Click this if you have added or removed modems or changed the connections settings.

When all items in the list have been polled once, the polling is paused for this many seconds.

A new poll message is sent this many seconds after a response is received to the last message.

Controls how NMS messages are sent to the network by

SATEL NMS PC Monitoring and the master modem.

ï‚· Offline: Messages are sent immediately (But the

Delay settings do apply)

ï‚· Online: Messages wait in the Master Modem’s outgoing message buffer until a DATA message going to the same address is being sent. The message is attached to the data message.

ï‚· Anycast: Requires modem firmware version 4.0.14.0 or later. Messages wait in the Master Modem’s outgoing message buffer until any DATA message going to any modem of the network is being sent.

The NMS message’s DADDR is set to the same value as the data message’s DADDR and it is attached to the data message.

73

This trigger causes an alarm when triggered

The trigger is only compared to received values with the same NMSID as in the

Trigger definition. Click the “Select” button to select the NMSID.

NOTE: A Trigger will never match if the same NMSID does not exist in the Poll

List. (Because in that case the value is never received from the network)

Which modems the trigger applies to.

It is usual to select all modems in the system, but in some cases it may be useful to match a trigger only to values received from a specific network or modem. For example, it may be permissible for some substations to reach temperatures of 40 degrees, but important repeaters and master modems must remain at 35 degrees or below. (Note: these are arbitrary numbers used as an example only.)

In these cases, specific triggers may be defined for each different case.

This setting causes an alarm in SATEL NMS PC Monitoring when the Trigger matches. The alarm is shown in the alarms view of Monitoring, a red message is displayed in the window and an alarm log is written into the directory specified in

6.9.3.

7 SATEL NMS PC MONITORING

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

This chapter describes the SATEL NMS PC Monitoring program. At the beginning of the chapter there is an overview of the features and instructions for common tasks. Towards the end of the chapter all the windows and views of the program are explained.

7.1 Overview

SATEL NMS PC Monitoring is intended to perform the following functions: o Regular polling of diagnostics variables from a radio modem network using SATEL

NMS Protocol o Writing of monitoring logs (including traffic, trigger, action and custom logs) o Displaying of trend graphs and other diagnostic information o Executing actions based on the values of and changes in the diagnostic variables.

Monitoring cannot be used to make any changes to the network settings.

Since Monitoring is a separate executable, it can be run with different user privileges than the

Setup program. In particular, it is usually a good idea to restrict access to Setup for certain key persons, while Monitoring can be installed to a wider user base.

7.2 Common tasks

7.2.1 Starting the program

Once you have a fully setup system created using SATEL NMS PC Setup and saved in a .sax file, you can start monitoring. Monitoring can be started in one of two ways: o From within SATEL NMS PC Setup, by clicking Start NMS PC Monitoring in the

Monitoring settings view. The .saxd file is loaded and monitoring started automatically. o By starting SATEL NMS PC Monitoring from the Windows start menu, command line, shortcut etc. In this case, you need to load the .sax file separately using the menu command File->Open, unless the .sax file name is given to Monitoring as a command line parameter, in which case the file is loaded and monitoring is started automatically when the program starts.

If Windows is configured to log in automatically and a shortcut to Monitoring (including the .sax filename) is added to the Windows Startup folder, the program will be started automatically if and when the PC reboots.

If your own DATA system is running and you are sending NMS messages (monitoring is on) in the OFFLINE mode, message will collide sometimes. How often, depends on the polling interval of your system and the monitoring. Switch monitoring to use ONLINE mode to remove collisions, OR make polling interval(s) longer to lessen the amount of collisions.

ONLINE mode depends on user data to reach the modems. Since the master is directly connected using a cable, it responds.

Either start the user data traffic or go to NMS

PC Setup, Monitoring settings and switch to

OFFLINE mode.

8 SATEL SERIAL SERVER

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

This utility program allows multiple SATEL NMS PC programs to access the same (or different) serial ports. It is therefore a serial port multiplexer for NMS traffic. It can also convert IP connections into serial port connections. The serial port settings can be pre-configured in SATEL

Serial Server or changed from the client NMS PC Setup using S3CP.

Most of the time Serial Server works transparently in the background but sometimes it may be useful or necessary to use it for some special configuration.

8.1 Overview

SATEL Serial Server is a separate program executable. It is meant to perform the following tasks: o Act as a multiplexer and translator between SATEL NMS PC client programs and the serial ports of the PC. o Allow installing and using the client programs from a different PC than the serial ports are located in. (Using TCP/IP) o Allow the possibility to configure default serial port settings for direct TCP/IP access

SATEL NMS PC Setup and Monitoring act as clients to Serial Server’s server. The clients access the server using TCP/IP sockets. For this reason Serial Server is configured to listen at a TCP/IP port, usually 55555, though this can be changed.

The TCP/IP traffic uses RAW sockets, and the protocol used is called S3CP (SATEL Serial Server

Command Protocol). Usually this protocol is completely invisible to the user and there is no need to be concerned over it. (Protocol documentation available separately)

S3CP includes commands to handle serial ports and send and receive NMS messages. Serial server translates the TCP/IP requests to SATEL NMS Protocol messages which are passed to the serial ports and this way to the NMS (diagnostic) port of the Radio Modem. The responses from the modem are translated back to S3CP and sent to the client.

An alternative way to form a connection from NMS client programs to the NMS Port of a modem is to define a direct TCP/IP port mapping. In this way, Serial Server can be configured to listen at another (or more) TCP/IP port number(s), for example 55556, which is then directly mapped to a serial port, for example COM1. This kind of mapping also requires pre-defining

serial port settings, such as baud rate, parity etc. See 8.3.3 for more information. If this kind of

connection is used, the client SW must be configured to use a Direct TCP/IP connection, see

6.8.1.1

96

8.2 Common tasks

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

8.2.1 Accessing the Serial Server User Interface

Serial server is started by other SATEL NMS PC Programs as they need it. If you need to use the user interface (views) of Serial Server, the window can be accessed by clicking the icon in

Windows Task Bar.

Figure 47: Serial Server icon

When the Task bar item is clicked, the window opens.

Figure 48: Serial server log tab

Note that usually serial server does not need to be configured or accessed in any way. The NMS

Client programs automatically start Serial Server in the same PC and communicate with it. Only if you wish to define default serial port settings and/or change the serial server preferences do you need to open serial server.

8.2.2 Using serial ports of another computer

If the serial ports and the NMS programs are located in different PC’s, the Serial Server must be installed into the PC having the ports, and the programs in the other PC can communicate with it over TCP/IP and use the serial ports. In this case the serial server must be started manually or from the Startup folder of Windows, for example.

See 8.3.3 for more information.

97

8.2.3 Troubleshooting serial port problems

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Some problems with serial port hardware can cause the serial ports to get stuck, unable to be opened or become unresponsive. Some serial port hardware or drivers cannot tolerate the port being opened or closed quickly. For this reason Serial Server by default keeps the ports open for

15 seconds, rather than open and close them in quick succession. See 8.3.4 for hardware

compatibility settings if you are having problems.

8.2.4 Command line use

Serial server can be used directly by opening a terminal connection to its command port (default

55555).

We recommend using putty.exe. Configure the connection as a RAW connection (no telnet control codes or SSH!) By writing “help” and pressing enter you can get a list of commands and instructions.

8.3 Server views

8.3.1 Server Log

This view (Figure 45: Serial server log tab) shows information about the server. It shows incoming TCP/IP commands from NMS Client SW (NMS PC Setup and Monitoring), NMS

Messages sent to and received from the Serial ports, and miscellaneous server messages.

8.3.2 Serial port list

Description

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

Explanation

Serial port name/number

Open: A client has opened the port and is using it

Open_x0: No client is using the port, but Serial server is keeping it open because the KeepOpen feature is in use ( See 7.3.3 )

Open_x2 (or more): Several NMS PC client programs are sharing the port

InUse: The port is in use by a program (or serial server itself if update has not been clicked)

Available: Port is not in use by any program unknown: Automatic port status detection (See7.3.3) is off and Update has not been clicked, the port’s status is unknown.

If status begins with Open, shows the port speed which Serial Server is using for that port. If Status is anything else, shows the default port speed that will be used if the port is opened without the opening software specifying a speed. This can happen for example if a direct TCP/IP connection is opened

(See 7.3.3)

Anything said about the BPS column and status also applies to this column.

Shows the other settings of the serial port.

The first number is the number of data bits: 7 or 8

The second character is the parity settings: N(o parity), E(ven parity), O(dd parity), M(ark) or S(pace).

The third character is the number of stop bits:0, 1 or 2

Usually 0. This means no direct IP port has been mapped to this serial port.

Other numbers indicate that a direct IP port HAS been mapped (See 7.3.3)

If a description has been given for the port, it is shown here (See 7.3.3)

User Manual Version 2.5

This tool program is used to define packet filters settings used by Master Modems in NMS

Routing mode networks to extract addresses from outgoing data packets for use in routing.

There are several protocols already supported as well as some general-purpose and example packet filters included with SATEL NMS PC. In case these are insufficient to your needs, you may define your own packet filters to use with your program.

SATEL technical support also can help in defining filters for your needs.

10 LOG FILES

SATEL NMS PC Version 2.0.18

User Manual Version 2.5

SATEL NMS PC programs will write some log files. Some of the programs also contain logs which are not written to disk, but can be viewed in the program window and copied to the clipboard. The user can also cause SATEL NMS PC Monitoring to write custom log files during

monitoring by defining certain triggers and actions. (see 6.9.3.1 Adding or editing an Action)

Whenever a program adds a new log line to the log file on disk, the program will do so according to the following procedure:

1. open the file

2. write into it

3. close it

This makes it possible to import data into other programs in almost real time from the log file, because the log file is not reserved for exclusive use by the program. Any reading program must also take care to open the file for shared read-only access so as not to prevent the writing.

10.1 Log types

SATEL NMS PC Monitoring will write a log file to the location defined in monitoring settings of

SATEL NMS PC Setup. The log file is a Tab-separated file. There is one log entry per line.

One log file per day will be generated. The log files are named in the following format: satelnms yyyymmdd.log where yyyy is the year, mm is the month and dd is the current day.

Monitoring and the network was allowed to run for a few minutes. At first, modem 2 was without power, which caused the No response entries in the log. The Voltage was kept below 12 Volts for both modems, which caused the Voltage Low entries. The radio connection was poor (No antennas & low TX power), which caused the “RSSI Low” entries in the log.

NOTE: The email sending functionality is not included in SATEL NMS PC. An external email sending application must be used. In this example, a program called sendemail.exe is used.

SATEL is not affiliated with the maker of this program in any way, and does not offer user support for the program beyond this document.

11.2.1 Preparation

Define the network and polling and trigger settings similarly to the previous chapter.

11.2.2 Action setting to send email

Install an email sending program, such as the sendemail program

( http://caspian.dotconf.net/menu/Software/SendEmail/ ) or Blat (http://www.blat.net/)

Test the program using the windows shell (Start->Run->cmd.exe) first. When you know which command line options are needed to send email in your environment, you are ready to define the Action.

Go to Monitoring->Action settings tab (see 6.9.3). Click Add. Select the Execute a command

Tab, and fill in the fields.

Command is the full name including path to the sendemail.exe

Parameter list is the command line including all the options necessary.

You may use the SATEL $variables$ to include information about the alarm in the email message.
