SMP Gateway User Manual 1

Welcome

Congratulations on acquiring your new SMP gateway! You now have unlimited connectivity for

all the equipment in your substation.

In this manual, we will show you how to use the SMP to integrate existing and new RTUs, IEDs,

PLCs and control centers into a single modern, homogeneous substation automation system.

You will learn how to set up your SMP as a:

Protocol Translator The SMP translates standard or proprietary device protocols to control

center protocols such as DNP3, TEJAS, IEC-60870-5-101/103/104 or IEC-61850 (UCA 2.0).

Data Concentrator The SMP collects the data from all connected devices, regardless ofprotocol, and makes it available to control centers using LAN, WAN, modem or serial

connections.

Terminal Server The SMP supports centralized maintenance, monitoring and control of alldevices by using the pass-thru communications mode.

Substation Communications Gateway The advanced capabilities of the SMP make it theideal choice for any substation automation project.

SMP models

There are currently 3 SMP models:

The SMP 4has 4 ports. It comesin a compact and economical format that allows it to be

installed directly within relay protection enclosures. There is also an optional internal modem

available, which allows the SMP 4 to communicate with a SCADA or device via a dialup

connection.

The SMP 16, which can be mounted in a 19-inch rack, comes in two versions, both of which

have the same basic characteristics:

The SMP 16/CPis a gateway that offers 16 RS-232/422/485 universal serial ports,

2 Ethernet ports and an integrated modem.

The SMP 16/SGhas, in addition, expansion slots where accessories and options can be

added to make it an ideal communications gateway for all your automation projects.


14/224

2 SMP Gateway User Manual

Both versions can also be equipped with the PM option, a new 1.1 GHz Pentium-M

processor, that improves the gateway's speed tenfold. This is ideal for high-capacity

application or complex automation schemes.

Principles of operation

Introduction

Electrical power utilities face a number of challenges when attempting to automate their

substations. They have legacy devices that they want to continue using. They want to integratenew devices. They may want to add one or more control centers. They may want to use a local

HMI in order to keep a close watch on all events that occur in the substation.

There are a number of problems to contend with: connectivity, protocol incompatibilities,

interoperability problems, security considerations, logistics for migration, downtime, and not theleast of which, total project cost.

The SMP gateway has been specifically designed to address all these issues. It is the ideal product

to ensure a smooth, safe and cost-effective approach to substation modernization. Indeed, you can

use a step-by-step approach. You decide which steps to take, in which order, and when.

Logical architecture

The SMP is designed to meet all the requirements for power substation automation. It has an openarchitecture that allows you to easily add new protocols, devices, local area networks, wide area

networks, and control centers.

In this section, we will describe the logical architecture of the SMP gateway and we will see howit implements all the functions required of a substation gateway.

Masters and slaves

A typical automation system consists of a SCADA system, located in a control center, which isconnected to devices located in the substation. The SCADA regularly polls the devices in order to

retrieve device readings and statuses. The operator uses the SCADA system to perform control

functions on selected devices.

Since it is the control system that initiates data acquisition and control, it is considered to be themastersystem. Since the substation device responds to data acquisition and control requests, it is

considered the slavesystem.

Figure 1 Master and slave systems

Introducing the SMP in the automation systemWhen an SMP is introduced in the automation system, it has to act as both a slave and a master.The SCADA system interrogates the SMP as if it were a substation device. The SMP is thus a

slave to the SCADA. However, since the SMP is connected to the substation devices, it must also

be able to perform the functions of a master, such as polling for data and sending control requests.

SMP internals

The SMP's internal architecture is based on a series of software components called protocolcomponents. Slave protocol componentsimplement all the functions necessary to process

requests received from a SCADA or control center. Master protocol componentsimplement the

functions necessary to poll devices and send control requests. Cybectec provides components for

most standard protocols, such as DNP3, MODBUS, IEC-60870-5-101/103/104 and IEC 61850, as

well as a large number of proprietary protocols such as SEL, ABB TEN BYTE, Motorola MDAC,

and more.

The master protocol component polls the device and stores the data that it retrieves in an internal

database, called the Real-Time Data Exchange (RTDX). The RTDX is much more than a simpledata store. Besides storing the current value of all the device data points, it also stores the different

types of information than can be provided by a substation device, such as the quality and

timestamp of the data. It also stores information such as device tags used for control functions.

Communication components

SMP protocol components process the messages exchanged among the control centers and the

devices. However, these messages can be transmitted using various communication methods. Forinstance, the MODBUS protocol can be used on a TCP/IP network or on an RS-232 serial link.

SMP communication components implement all the functions required to communicate with adevice or control center using a variety of communication technologies. Cybectec provides

communication components for asynchronous serial ports, RS-232, RS-422, RS-485, TCP/IP and

modems.

Configuring the SMP

The SMP configuration process consists of establishing the relationships among the internalcomponents, and providing the specific settings for each of these components. This task is greatly

simplified by Cybectecs SMP Toolsfamily of software programs. These Windows-based

programs help you configure your SMP and identify and correct any problems.

The configuration process consists of the following steps:

Identifying the SMP model and the installed options.

Creating a master protocol component for each device that is connected to the SMP.

Defining all the data points in the device.

Defining the communications link to be used to connect the device to the SMP.

Creating a slave protocol component for each SCADA or control center.

Defining the data points that the SMP will report to the SCADA.

Defining the communications link to be used to connect to the SCADA.

Adding a firewall and optionally a security server that supports corporate network users.

Thus, the configuration settings define the functions that the SMP performs. These settings are

stored in a file that you load onto the SMP. The flexibility of the SMP architecture is the basis of

Cybectecs step-by-step substation modernization strategy.

In the following sections, we will show you how you can configure the SMP to perform all the

functions required of a substation gateway.


24/224


Step 1 The transparent SMP

As a first step in a substation automation project, you can easily set up the SMP to act as a

transparent interface between the SCADA and a substation device. The following diagramillustrates how you can do this for a MODBUS protocol.

Figure 5 The transparent SMP

In this configuration, the master component polls the device and stores the values in the RTDX.The slave component processes the SCADA polling requests and sends the values provided by the

device.

There is not much use for a transparent SMP. However, it contains much more than thecomponents that we described previously. Simply by adding the SMP to the substation, you now

have access to the following advanced functions:

Centralized automation functions, using the built-in Automation functions or the IEC 61131-3

Soft PLC logic processor.

Real-time data display, using the built-in web server.

Transparent access to devices, using the passthru server, for local or remote IED maintenance.

SNMP support to monitor communication status.

Sophisticated HMI, interactive diagrams, data logging and reporting, using CybectecsVisual Substationsoftware.

Sophisticated Windows tools for remote or local maintenance.

A sophisticated security server to support corporate network users.

Even more important, the transparent SMP is the first step in integrating new substation devices toyour existing SCADA and automation system.

As we saw in the last section, the SMP is transparent when the master and slave protocols are the

same. When you configure different master and slave protocols, the SMP becomes a protocol

translator.

Since you can independently configure the communication links for the master and slavecomponents, you can easily use the SMP to integrate legacy serial devices in a modern network

environment. Similarly, you can connect modern IEDs to a legacy control center.

Using the SMP as a data concentrator or device multiplexer

The SMP architecture is designed to simultaneously support any number of master components.

Each component has its own communications link and its own protocol. All the data retrievedfrom the devices is stored in the RTDX, where it becomes available to the SCADA. Using the

SMP as a data concentrator is a simple matter of configuration, and it provides a highly efficientmeans of adding new devices to an existing automation system. The SCADA system has noknowledge of the new devices; it only sees new data points.

Securing the substation

Widespread data access within the SMP Substation Gateway can become an important securityrisk if it is compromised, but it can also become a security asset. This is why the gateways are

ready for NERC CIP-002-1 to CIP-009-1 Cyber Security Standards. The gateway provides a

single point of access to all substation data. The security features of the SMP gateway allow youto protect the substation devices (see Figure 11).

If you activate the security features within your substation SMP you will be able to:

Comply with authentication and authorization policies.

Set-up a firewall to protect from substation LAN security breaches.

Monitor and lock out remote connections; and have a file integrity check on the SMP files.


30/224


The access inside the firewall protection has additional layers of protection, so that only a few

users of your choice will have the possibility to modify parameters inside the substation.

Figure 11 The SMP substation gateway with a firewall

In the following chapters, we will learn how to configure the SMP to perform these functions.


31/224


The SMP Tools

To assist you with the tasks you will want to perform with the SMPs in your organization, we have

provided you with our suite of SMP Tools.

The SMP Tools are Microsoft Windows-based programs that make it easy for you to configure

the SMP gateway and perform maintenance functions. They run on a PC, are simple to use, and

provide advanced features that allow you to rapidly configure all the devices and communicationlinks in your substation. They can be used locally or remotely through a LAN, WAN or VPN.

When security is activated, users must log in before they can use any function.

The Cybectec SMP Toolsinclude the following applications:

SMP Manager

Manages all the SMPs in your organization. It displays the state of each SMP, manages their

configuration files, allows you to group two SMPs together to achieve redundancy, and isused to invoke the configuration and maintenance tools for any SMP to which it is connected.

From SMP Manager, you can also start Internet Explorer to view the data points, logs and

traces in real time, and you can start a Telnet session in order to set-up certain advancedfeatures such as dial-up access or IRIG-B signal output type.

SMP Config

Used to configure the SMP. It has a spreadsheet-like grid that you use to specify the devicesand control centers connected to the SMP, their protocols, their communication links and their

data points. Advanced editing functions make it easy for you to enter the data points.

Template editing allows you to pre-define standard devices with standard data points, therebyreducing labor intensity and the possibility of errors.

61850 Config

Used to configure the IEC 61850 and UCA 2.0 protocols on the SMP.

SMP Log

Used to browse through and manage the log files maintained by the SMP. All significant

events are logged, including local and remote control events, system failures, special protocolevents, and so on.

SMP Stats

Used to browse through and manage a large variety of dynamically updated statistics, ranging

from full communication statistics for each link to the processor load for each protocol

component.

SMP Trace

Used to browse through the real-time traces generated by the SMP. SMP Trace can display


32/224


detailed traces of all protocol and communications link activity. Traces are displayed in both

hexadecimal and application protocol format. The tracing functions are similar to those

usually provided by protocol analyzers, with the notable exception that they can be used

remotely at any time on any SMP and that they decode information at the application level.

As such, they constitute an excellent commissioning or debugging tool.

SMP ConnectUsed to establish passthru connections with any IED connected to an SMP, for the purpose of

doing remote configuration and maintenance of IEDs using manufacturer-provided software.

SMP Loader

Used with the SMP 4-20 and SMP 8-40 to load new versions of most of the SMP firmware

components, and with the SMP 4, SMP 16/CP and SMP 16/SG, to load the secondarybootstrap program. Refer to Appendix A and to your SMP installation guide for details on

using SMP Loader.

The next chapter will discuss how to create a list of SMP gateways with SMP Manager, and willthen explain how to do a complete configuration of your SMP using SMP Config.


33/224


SMP Manager

SMP Manageris the doorway to your SMPs. It runs on your PC, as do all the tools you launch

through SMP Manager. You are already familiar with the application, since you added your new

SMP to the list of SMP gateways managed by SMP Managerwhen you installed your SMP. This

section goes over a few of the points that were covered in your SMP installation guide, and

provides additional information.

Starting SMP Manager and logging on

To start SMP Manager:

On the Windows taskbar, click Start.

Point to Programs, then Cybectec, and then SMP Tools.

In the SMP Toolsmenu, click SMP Manager.

The SMP Managermain screen appears and shortly after the Login Informationdialog box

appears.

Just click OKto close the dialog box unless security is configured.


34/224


Main window

The following figure shows a typical SMP Managerwindow.

As illustrated, the main window displays information such as:

The list of SMP gateways and the tools that are currently running for each SMP gateway in

the list.

The current status of each SMP in the list (started, failed, safe mode, max safe mode, on

standby, and various intermediate states).

The SMP model: SMP 4-20, SMP 8-40, SMP 4, SMP 16/CP or SMP 16/SG.

The IP address and redundancy status of any SMPs you have grouped together for the purpose

of redundancy. This information is available only if your license supports redundancy. This

column is not available by default.

Whether the SMP's built-in firewall is active and whether VPN is connected or disconnected.This information is available only if your version of the SMP software supports the SMPs

security features. The firewall information is not available by default

You can choose which columns you want to display and their order of appearance, with a rightclick on the column header.

Adding an SMP

Creating a list of the SMP gateways you want to monitor is easy. Proceed as follows for each SMPgateway you want to add to the list:

In the SMP ManagerGateway menu, click Addto add your SMP gateway to the list.

The Gateway Propertiesdialog box appears.


35/224


Enter the name by which you want to identify your SMP gateway in Gateway Name. The

Configuration fileis the file that will be opened by default in SMP Config. If you change its

name afterwards through the Filemenu, you must come back to this dialog box and change

the name in the Configuration Filetext box, so it opens the right file at startup.

In the First Addressbox, type the IP address of the first Ethernet port. You can also type theaddress of the second Ethernet port in the Second Addressbox, although it is not necessary to

do so.

If the SMP gateway cannot be directly accessed through the network, but requires a dialup

connection, check the box The gateway is connected over a remote dial-upto prevent SMP

Manager from polling the gateway for its status.

Click Add.

The SMP gateway gets added to the list, and SMP Managerautomatically detects the model of

the new SMP and in the case of an SMP 4, whether an internal modem is installed.

Information provided by the SMP gateway icon

The SMP gateway icon, which is displayed beside each SMP gateway name, provides additional

information about the SMP gateway.

The following table gives the meaning of each icon:

Configuring the SMP

Introduction

As we saw under Principles of operation, you have to configure the SMP before you can use it.

For this, you use SMP Configto define the characteristics of your SMP and the functions it has toperform. The configuration is stored in a file that is then loaded onto the SMP, where it is stored in

non-volatile flash memory.

Using SMP Config, you will perform the following configuration steps:

For an SMP 4-20, SMP 8-40, or an SMP 16/SG define the hardware options installed.

Create a master protocol instance for each device to be supported.

Define each data point on each device.

Configure the communications link to be used to connect to each device.

Create a slave protocol instance for each SCADA or control center.

Configure the communications link to be used to connect to the SCADA.

Map the device data points to SCADA data points.

You will then use SMP Managerto send the configuration file to the SMP.

Note:There can only be one instance of SMP Config running at any given time.If you launch the tool for a given SMP and then launch it again for a second SMP,SMP Configwill prompt you to save any changes you have made, close theconfiguration file of the first SMP, and then open the configuration file of thesecond SMP.

To create a configuration file for your SMP gateway, proceed as follows:

Start SMP Manager.

In the SMP Managerapplication window, click your SMP gateway.

In the Toolsmenu, click SMP Configto start the application.


40/224


The SMP Config display includes 3 panes. The left pane is a tree structure of all the configurationtopics. The top right pane displays the settings for the topic you have selected in the left pane. The

bottom right pane appears when your request that the configuration be validated; it displays error

and warning messages.

The gateway name is the name you assigned when you added the SMP gateway in SMPManager. The configuration file name on the title bar was also assigned when you added the SMP

gateway in SMP Manager.

If you open the Master Protocolsand Slave Protocolsbranches, you will see that the treestructure offers you a fixed set of protocols. These are the protocols currently supported by your

product license.


41/224


Creating master protocol instances

You need to add a master protocol instance for each device you want to access with your SMP

(see Figure 2). Even if a number of devices share a multidrop link, each of them requires its own

master protocol instance. Each device is a slave, so the SMP acts as a master when communicatingwith the device, which is why it requires a master protocol instance.

There are two ways to add the master protocol instance:

You can use a template, which eases the task of configuring the master protocol instance, by

automatically entering the points list for the device. SMP Configprovides templates for anumber of common substation devices.

If no template is available, you will need to enter the points list. If you are configuring a

number of devices of the same type, you can save the first device configuration as a template

that you will then use to enter the other devices.

Once you have added a master protocol instance and entered its data points (manually or via a

template), you can click a particular data point type in the left pane and see the list of data points

and their settings in the right pane, as shown next.

Creating a master protocol instance from a template

To add a master protocol instance from a template:

In the left pane, open the Master Protocolsbranch, to display the list of master protocols

provided under your product license.

In the left pane, click the protocol for which you want to add an instance.The list of all defined master protocol instances appears in the right pane.

In the Tools menu, click New Instance From Template.


42/224


Choose the appropriate template, and click Open.

In the dialog box, enter:

The name of the new instance.

The device prefix.

The device prefix is a string that identifies the device and is used as a prefix for all of itsdata point names. The prefix ensures that every name in the system is unique. An

explanation of the usage of prefixes is provided under Configuring the master protocol

general settings, in the next sections.

The new instance appears in the left pane. If you open its tree structure and click the various

physical data point types, all the data points supported by the device will be displayed in the rightpane.

Creating a master protocol instance manually

To add a master protocol instance manually:

In the left pane, open the Master Protocolsbranch, to display the list of master protocolsprovided under your product license.

In the left pane, click the protocol for which you want to add an instance.

The list of all defined master protocol instances appears in the right pane.

In the right pane, enter the name of the new instance at the end of the list of names, and press

the Tabkey on your keyboard.

The new protocol instance is added in the left pane, under the protocol type you had selected. If

you expand its tree branch and click an item, the corresponding protocol settings will be displayedin the right pane. Note that if you click a physical data point type in the left pane, the right pane

will display an empty row since you will have to add the physical data points manually.

Configuring the master protocol general settings

All master protocol components share common settings that define how they interact with a

device. The following procedure describes how to enter these settings. If you created the protocol

instance from a template, the general settings have been defined for you. However, you shouldverify the settings to make sure they match your device configuration, and you should familiarize

yourself with the naming conventions discussed in this section.

In the left pane, click Generalto display the list of general settings for the selected protocol.

In the right pane, enter a Device Prefix.

The string you enter will be used as a prefix for all the I/O point names of the device. It ismandatory for each instance of a protocol. It is used to distinguish data point names that are

on the same device type, but on multiple physical devices. The device prefix ensures thatevery data point name in the system is unique. Device prefixes are described in the following

section,Adding data points from a protocol template.

Device prefix and naming conventions


43/224


A typical substation automation project requires the configuration of thousands of data points.

You can significantly reduce the effort by carefully planning how to name devices and data points.

Cybectec tools provide additional functionality if the names of data points are based on some type

of convention. For our engineering projects, we use a naming convention such as the following:

A data source name, such as the substation name: MAPLE, CEDAR.

A voltage level: 220or 25.

A device name: L1to indicate a line, T1to indicate a transformer, F1to indicate a feeder,BUSfor a bus bar.

A signal name: V_phsA_magto indicate the phase A voltage magnitude, A_phsA_magtoindicate the phase A current magnitude, Pos_stto indicate the status of a breaker or a lineswitch.

With such a convention, a data point called CEDAR_220_BUS_V_phsA_magclearlyindicates the voltage magnitude of phase A on the 220 kV bus of the CEDAR substation. A data

point called MAPLE_025_F1_Pos_stindicates the status of the breaker switch of feeder 1 atthe MAPLE substation.

Still in the Generalsettings, enter the scanning settings.

For instance, to configure a MODBUS master protocol, you would provide settings such as

the following:

A Device Address, typically 1.

A MODBUS Type, typically RTU Serial.

A Scan Interval, typically 1000 ms.

A complete description of all settings is provided in the document entitledMaster Protocol

Common Concepts. Protocol-specific settings are described in individual documents, such asDNP3 Master Protocol.

Accessing protocol-specific documentation

There are Cybectec documents available, to which you can refer for details on the settings of the

currently supported protocols.

To access the documents, proceed as follows:

Click Start, on the Windows taskbar.

Point to All Programs, then Cybectec, then SMP Tools, and then Documentation.

In the Documentationmenu, click Protocols.

The list of available documents is displayed in an explorer window.

Click the document you want to read.

In the Filemenu of the explorer window, click Open with Acrobat.

Your Adobe Acrobat program starts up and displays the document in a window.


44/224


Configuring the data points

Once you have provided the general settings of the protocol component, you then enter all the datapoints on the device. If you created the protocol instance from a template, all the data points have

already been added; however, we suggest you read this section for your information.

Protocol components typically support physical and logical data points of the following types:

Analog inputs

Binary inputs

Analog outputs

Binary outputs

A physical data pointrepresents a real-life value, implemented on an external device. You need

to identify all the device data points, either manually or using a device template.

A logical data pointis a value managed by the SMP. These data points are built-in and cannot be

modified, but they can be disabled.

Analog inputsare measured values. The system keeps 2 values for each analog measurement

obtained: a raw value, which is usually the value retrieved from the device, and a calculated value

expressed in engineering units, obtained using the following standard formula:

Engineering value = Raw Value X Scaling Factor + Offset

Binary inputs represent the state of a data point. The state is either ON or OFF.

Analog and binary outputs are typically initiated by a slave component, which sends a control

request originating from a control center, to the master component involved.

When you create a data point, you specify the type of data and you indicate how the SMP will

retrieve it. General properties such as name, type and units, are independent of the type of device

or protocol used. Protocol-specific properties indicate how the SMP will retrieve the data from thedevice. Each protocol uses its particular form of addressing, such as index values or data offsets.

For example, to add a data point for a MODBUS device:

Click the appropriate branch under the protocol instance.

In the right pane, enter the name of the data point and fill in all the appropriate settings.

For instance, to define an analog input you would provide the following settings:

The name of the data point, such as BUS_VA. SMP Configwill automatically add the

device prefix to this name, thereby generating the full name of the data point.

The input source, such as Input Registers.

The input format, such as Unsigned Integer.

The input size, such as 16or 32bits.

The word offset in the MODBUS device memory.

The scaling information required to convert the raw value to engineering units.

The Unitsand Descriptionstrings used to provide meaningful data displays.


45/224


A complete description of all settings is provided in the document entitledMaster Protocol

Common Concepts. Protocol-specific settings are described in individual documents, such as

Modicon Modbus Master Protocol. A complete description of system data points can be found in

System data pointson page 196of this manual.

To access the various protocol documents:

Click Start, on the Windows taskbar.

Point to Programs, then Cybectec, then SMP Tools, and then Documentation.

In the Documentationmenu, click Protocols.

Adding data points from a protocol template

Protocol templates can also be used to add points to a protocol component. For instance, you could

use a template to add the data points provided by an optional device feature. You can do this by

retrieving the data points from a protocol template.

To do this:

In the left pane, click the protocol instance to which you want to add the data points.

In the Tools menu, click New Points from Template.

A standard Windows Open dialog box appears.

In the Templatesfolder for the protocol type you selected, choose the .tpl file you want to

use, and click Open.

A dialog box appears, prompting you for the optional prefix and suffix to be added to every new

data point name. The upper portion of the dialog box provides information about the open

template file, while the lower portion shows warning and error messages.

Specify a prefix and a suffix, if applicable.

The new data points now appear in their respective categories under the selected protocol instance,

and their names contain the specified prefix and suffix.

Note that the prefix and suffix are not applied to logical data points, and that the logical data

points are reset every time you add data points from a protocol template. You should, therefore,

configure these data points once you have completed the list of physical data points.


46/224


Creating a template from a master protocol instance

You can create a template of a master protocol instance, which you can retrieve later in order to

quickly generate new protocol instances.

To create the template:

In the Filemenu, click Save As Template.

Choose the Templatesfolder in which you want to store the template, and click Save.

Note that a template file can contain only one protocol instance. So if you want to create templates

for several protocol instances, create a new configuration for each one and save individualtemplates.

Duplicating a master protocol instanceOnce you have created a master protocol instance and configured its data points, you may want to

generate one or more additional instances with the same general and data point settings. A quick

way to accomplish this is by duplicating the master protocol instance.

To do this:

In the left pane, click the protocol instance you want to duplicate.

In the Toolsmenu, click Duplicate.

A dialog box appears, prompting you for the instance name and device prefix, as shown in the

following.

Enter the name and prefix of the protocol instance, and click OK.


47/224


The new protocol instance now appears in the left pane.

Configuring the communication links

A protocol component communicates with a device or control center using one of the following: a

serial link, a modem or a TCP/IP network. The configuration of a communications component iscompletely independent of the protocol used. Before you connect a device to the SMP, you have

to choose and configure the communications link.

Configuring the serial port interfaces

Depending on the options you choose in the hardware configuration, you can configure the SMP

serial ports to support RS-232, RS-422 or RS-485 communication.

Click Serial Portsin the left pane, to display all the available ports.

For each port, choose the type of interface to be used. Most substation devices typically use

either Asynchronous RS-232or Asynchronous RS-422/485. If you are using a serial port fora touch screen, select ELO Touchscreen.

Serial port naming conventions

The SMP 16 provides 16 serial ports, identified as A01through A16. It also has a modem port

labeled Modem, which has a Modem Asynchronous interface. The SMP 16/SG can also

house up to 2 additional serial ports boards, that will be identified as B01 to B16 and D01 toD16.

The SMP 4 and SMP 4-20 both provide 4 built-in serial ports. These ports are identified as

COM1 Board Athrough COM4 Board A.

The SMP 4 also provides a built-in console serial port. This port is identified as Built-inConsole 1 Board A. This feature allows you to use the Console port as a standard serial port.

If the SMP 4 has an internal modem, then it provides 3 built-in serial ports and 1 built-in

modem port. These ports are also identified as COM1 Board Athrough COM4 Board A;however, the Interfacecolumn in the right pane indicates that the interface for COM4 Board

Ais Modem Asynchronous.

The SMP 8-40 provides 4 additional ports named COM1 Board Bthrough COM4 Board B.

The SMP 4-20 and SMP 8-40 SIOM use IPack modules to provide additional ports in groupsof 8. The ports in the first group are called IPack_A1 Board Athrough IPack_A8 Board A.

The ports in the second group are called IPack_B1 Board Athrough IPack_B8 Board A.

The SMP 8-40 supports two additional groups of ports called IPack_A1 Board BthroughIPack_A8 Board B and IPack_B1 Board Bto IPack_B8 Board B.

The purpose of each interface is given in the following table:

Interface Description

Asynchronous RS-232 Use this value to indicate that the serial port is dedicated to establishinga standard asynchronous RS-232 connection.


48/224


Interface Description

Asynchronous RS-422/485 Use this value to indicate that the serial port is dedicated to establishingan asynchronous RS-422 or RS-485 connection.

Modem Asynchronous This value indicates that the port is used for modem asynchronouscommunication. The value is automatically assigned to the Modemport

of an SMP 16 and to the COM4 Board Aport of an SMP 4 equippedwith an internal modem.

RAS (remote access server) Use this value to indicate that the serial port is configured to acceptincoming direct serial connections. This type of connection allows you

to use the SMP Toolsas if you were connected to the SMP via a normalnetwork connection. By default, the console port is always configuredfor RAS.

Refer to the SMP 4 Installation Guide, GUI-00316-00026 T, or to theSMP 16 Installation Guide, GUI-00316-00032 T, for instructions on

setting up a RAS IP address pool. Then refer to Remote access to theSMP gateway, page 171, in the present manual, for the step-by-stepinstallation procedure.

Constraint for the SMP 4-20 and the SMP 8-40:

An SMP CPU board can support up to 4 different bit rates for the serialports located on the front panel. This means that if you specify that the

console serial port is configured for RAS, only 3 other bit rates will beavailable for the remaining 4 serial ports on Board A and that if all theother Board A serial ports are used, 2 of the 5 serial ports must have thesame bit rate. Note that if you set the console serial port toReserved and

you do, in fact, accept incoming direct serial connections on the consoleserial port as well as on the 4 remaining serial ports, the SMP gatewayapplication will disable the console port connection. This constraintobviously does not apply to Board B, since it has 4 serial ports and there

are 4 bit rates available.

Redundancy Use this value to indicate that the serial port is reserved for connecting2 SMPs together as a redundancy group. See Error! Not a valid result

for table., page 149.

Reserved Use this value to indicate that the serial port is reserved for purposes

other than those stated previously.

Configuring the operation of the serial ports

Each serial port needs to be configured with the appropriate settings for the connected device.

In the left pane, open the Connectionsbranch to display all the supported connection types.

Click Asynchronous Serial Portsto display the list of available ports.Note that if you choose Redundancy as the interface for a serial port, that port will not

appear in the list of Asynchronous Serial Ports, as it will be reserved for connecting the

2 SMPs that will be grouped together.

In the right pane, enter the settings for the selected serial ports.The required settings are usually provided in the device manufacturers reference manual:


49/224


If you are using RS-485 2-wire communication, choose RS-485. If you are using RS-485

4-wire communication, choose RS-422.

Choose the device communication settings: baud rate, byte size, parity and number of

stop bits, such as 9600 baud, 8 bits, no parity, and 1 stop bit.

Choose the device hardware handshaking mode:

If the link type is RS-232, most devices do not use handshaking, so you should keepthe default values: RTSto Always On, DTRto Always On, and CTSto Ignore.

If the link type is RS-422, set RTSto Always On. You shouldnt have any problem

if you keep the other default values: DTRto Always On, and CTSto Ignore.

If the link type is RS-485, set RTS to TX Request. You shouldnt have any problem

if you keep the other default values: DTRto Always On, and CTSto Ignore.

If you are using RS-422 or RS-485 communication, specify whether or not you will be

using line terminators. Refer to your SMP installation guide for a discussion of

termination resistors.

Configuring TCP/IP connections

TCP/IP connections are most often used by slave components to connect to control centers.

However, an increasing number of modern IEDs can be connected to a substation LAN using a
