IP Gateway System and ToolBox Software Version Policy

The version numbers of the ToolBox and system software are updated according to additional
features and improvements.

Compatibility (at source level) between the ToolBox and the IP Gateway is assured only if the

version number of the ToolBox Software is later than the version number of the Gateway
system software.

A version number is composed of two numbers, as in the following example: V1.61. The one­digit number to the left of the decimal point describes a major modification of the software,
while the two-digit number to the right of the decimal point describes a minor modification.

In this manual, some headings of major subjects are marked by the following annotation:
≥

Va.b.

For example, ≥ V1.61 indicates that the marked subject is supported by a Gateway whose
system software version number is at least 1.61.

Introducing the IP Gateway

The IP Gateway for SCADA and NFM systems is a smart unit, based on the Motorola 68360
microprocessor and includes on-board memory, communication channels, indicator LEDs and
other circuits. It provides the SCADA and NFM software with access to the MOSCAD system,
based on the seven layers of the MDLC protocol, in order to exchange data with the RTUs. A
typical example of the IP Gateway is shown in Figure 1-1; a SCADA control center is
connected via the IP Gateway to a radio link of the MOSCAD system.

Figure 1-2: IP Gateway with Multiple Vendors SCADA Control Center
The SCADA control center, which includes workstations and a SCADA computer, exchanges

data with the MOSCAD system via the IP Gateway, which serves as a Gateway from the
TCP/IP world to the MDLC world. There are many SCADA packages which already have the
Gateway Interface driver implemented, some as direct access to the IP Gateway, and some as
OPC server.

IP Gateway Applications

The IP Gateway uses the TCP/IP LAN Protocol for exchanging data application messages with
the SCADA software. The IP Gateway API (Application Programming Interface) source
library allows SCADA developers to quickly and easily connect to the MOSCAD world. The
IP Gateway API, which is part of the IP Gateway product line, allows SCADA driver
developers to quickly and easily build the IP Gateway Interface (driver), which serves as a
communication interface with the MOSCAD world.

Data exchange between the SCADA (client) and the IP Gateway (server) is carried out using
"peer -to-peer" communication over the LAN. The IP Gateway can support multiple
connections that are initiated from multiple SCADA computers.

The implementation of the IP Gateway interface in the SCADA software allows the SCADA
to perform the following:

• Poll a MOSCAD RTU in order to get data and COS (Change-of-State) events from the

RTU tables.

1-3

Introduction

• Send commands to the MOSCAD RTU and download parameters to its local process.

• Send commands via broadcasts to any required group of RTUs.

• Download parameters (set-points) to the RTU local process.

• Receive spontaneous reports (by contention) from RTUs (both burst and event

transmission).

• Receive time-tagged events logged in the RTUs (1 msec resolution).

• Adjust the RTU clocks (1 sec resolution).

• Synchronize the RTU clocks (1 msec resolution), using an external CPU with GPS.

• Support redundant IP Gateway configuration.

• Set the Gateway mode (Primary/Secondary).

• Retrieve Gateway status.

• Retrieve RTU links status.

MOSCAD NFM Overview

The MOSCAD NFM system provides communication providers with a solution for
supervising and controlling the operation of conventional and trunked radio, analog and digital
cellular, microwave radio and wireline telecommunication systems.

The MOSCAD NFM system provides the Network Management Center (NMC) with access to
the communication and environmental devices and gives the operator and the system manager
the tools needed to identify and fix faults within the communication system.

Figure 1-3 describes the general architecture of the MOSCAD NFM, which includes control
center workstations and computers that exchange data with the IP Gateway, allowing the NMC
to monitor and control non-SNMP devices at the communication sites.

Figure 1-3: General Architecture of the MOSCAD NFM System

The MOSCAD NFM via the IP Gateway allows the system to offer SNMP (Simple Network
Management Protocol) connectivity, therefore providing a standard interface to a wide range
of NMC platforms (such as HP/OpenView, SUN/Solstice, IBM/NetView etc.).

The MOSCAD Remote Terminal Unit (RTU) represents the Element Level of the network
management model. It collects the various inputs, outputs and analog signals via a variety of
input/output (I/O) modules. In addition, the MOSCAD RTU serially interfaces to
communication devices (radio, cellular and telecommunication) and is able to emulate (speak)
their ASCII based native protocol, allowing the MOSCAD to not only monitor alarms, but to
configure and change parameters as well.

IP Gateway System Overview

SCADA System

The complete control system is comprised of the SCADA control center (or centers)
communicating with MOSCAD RTUs over various communication links, such as:

• conventional radio

• trunked radio

• data radio, dial-up lines

• leased lines,

• microwave, fiber optic links

• combined networks

The communication system is used for transmitting alarms, status and telemetry, calculated
data diagnostics and error logging information from the MOSCAD RTUs to the central facility
computer and vice versa. It is also used for downloading, monitoring and debugging the
application program at the sites.

The system may be relatively simple, comprising several RTUs and a single control center, or
a more complicated hierarchical system, where several sub-control-centers communicate with
lower, parallel and higher hierarchies. The RTUs may also communicate with each other
and/or with any other hierarchy in the system.

The MOSCAD system uses the MDLC protocol, based on the seven layers of the OSI model
published by ISO, and adapted for SCADA communications. It provides network support,
multiple logical channels per physical port, allowing each RTU to simultaneously run several
communication sessions, such as data exchange, on-line monitoring, diagnostics, etc.

The MOSCAD system is supplied with a Toolbox, which is a software package that runs on an
IBM PC (or compatible). All RTU functions such as configuration, database and process
definition, downloading, monitoring, hardware and software diagnostics, etc. are defined by
means of the MOSCAD Programming Toolbox.

Figure 2-1 describes a typical MOSCAD radio system. The IP Gateway includes one Ethernet
port for connection to the SCADA computer and 3 serial ports for communicating via MDLC
protocol to the MOSCAD devices. In this particular case, one MDLC port is connected to the
MOSCAD Programming Toolbox and the second MDLC port is connected to a radio for
communicating with the RTUs.

System Overview

The IP Gateway allows the SCADA center to conduct a large number of sessions via a large
number of logical channels in spite of a single physical RS-232 port. The IP Gateway also
serves as an MDLC router between the MOSCAD Programming Toolbox and RTUs.

The Toolbox may be connected either locally to an RTU or via the MDLC port of the IP
Gateway to any RTU in the system. All programming and monitoring functions can be
performed either locally or remotely.

Note: The MOSCAD Programming Toolbox that is connected locally to one of the RTUs in
the system can service any other RTU in the system via the communication network.

Figure 2-2 describes multiple SCADA control centers which are connected to the IP Gateway
via a 10 Mbps Ethernet LAN. In this case, multiple TCP/IP logical links are used for
communicating with the IP Gateway, which is connected via multiple MOSCAD CPUs to
multiple MDLC links (Radio link, Line link, Dial-up link etc.).

Multiple SCADA control centers can simultaneously perform multiple sessions with the IP
Gateway in order to send commands and polling requests to the RTUs and to receive data and
contention reports from the MOSCAD RTUs.

MDLC Over IP

MOSCAD RTUs and IP Gateways can use IP (Internet Protocol) technology to interface to
advanced radio infrastructure (e.g. digital ASTRO IP conventional systems) and to standard
private IP networks. Most benefits of the MDLC protocol are preserved. MDLC and IP
networks can be integrated in the same system, as networking properties are preserved.
MOSCAD MDLC applications need not be modified as the lower layers of the protocol
support IP.

MDLC packets to be transmitted are enveloped inside IP datagrams and sent between remote
RTUs or between an IP Gateway and an RTU.

An IP Gateway can act as a gateway between the field and the SCADA Central to extract the
enveloped frames from the IP message. A ToolBox can be connected to one of the RTUs or to
the IP Gateway, either locally or over IP network.

Each RTU/IP Gateway is assigned a Site ID. In addition, each RTU/IP Gateway with an IP
interface is assigned an IP address. An IP conversion table which maps Site IDs to IP
addresses is created in the ToolBox and downloaded to the RTUs and IP Gateway. This
enables routing over the IP network to the proper destination.

Two variations of MDLC over IP exist, MDLC via Terminal Server and MDLC via Astro IP.

System Overview

MDLC via Terminal Server

If the RTUs are on a Local Area Network (LAN), each can be connected to a Terminal Server
attached to the Ethernet. The Terminal Server converts the RS232 to the Ethernet LAN and
enables communication with an IP Gateway, or between RTUs.

In the diagram below, a typical configuration is shown, with RTUs attached via SLIP (Serial
Line IP) port to a Terminal Server, which is in turn attached to Ethernet.

MDLC Over Private DataTac

MOSCAD RTUs can communicate over Private DataTac systems (RDLAP) with SCADA
centrals and with other RTUs. All MDLC features are preserved except for clock
synchronization.

RTUs are connected to RDLAP (DataTac) radios (e.g. VRM 500, 600, 650, 660, and TRM

660) via RS232. An RTU sends a message (MDLC), through the radio to the Radio Network
Controller (RNC). The RNC encapsulates the MDLC message and send it over IP to the IP
Gateway. The IP Gateway then extracts the MDLC message from the IP envelope and
transmits it to the appropriate destination. If the destination is another RTU over Private
DataTac, the IP Gateway must support the reflector feature, which enables it to “reflect” the
message back over RDLAP (DataTac).

The picture above shows a typical system which supports MDLC communication over RDLAP

(DataTac) radios. Note that the IP Gateway is configured as RDLAP (DataTac) reflector. A
host computer attached to the Ethernet can receive TCP/IP applications from non-MOSCAD
terminals on existing RDLAP (DataTac) systems, if required. A MOSCAD Programming
ToolBox can be connected to one of the RTUs, and can access another RTU by using its Site
ID and Link ID. ToolBox can also be attached to one of the serial ports of the IP Gateway.

SCADA Interface

Client-Server environment

The SCADA application for the IP Gateway is based on a client-server approach.
The IP Gateway application acts as a server while the SCADA Interface acts as a client. In

such a relationship, the SCADA Interface must establish the connections with the IP Gateway
needed for communicating with the MOSCAD RTUs.

After the connections have been established, the SCADA Interface can send data, commands,
and polling requests to the field RTUs. It can also establish a special connection that enables

2-7

System Overview

receipt of data transmissions initiated by the field RTUs (so called burst/RTU event data,
contention data or Change-Of-State [COS] messages).

A specialized routine, API CONNECT, allows the SCADA Interface to establish the most
fitting mode of communication with the IP Gateway, based on the existing SCADA
communication mode.

Channels and Channel types

The SCADA Interface must establish at least one connection toward the IP Gateway server.
These connections are called channels and are used to transfer messages from the SCADA
center toward both the Gateway and the RTUs in the field. The client application can open
different types of channels to best serve its SCADA Interface process.

The two basic channel types are:

• Regular

• Spontaneous

A Regular channel enables asynchronous sending/receiving of data and requests. It uses
amailbox mechanism for mapping the request messages to their replies.

A Spontaneous channel allows receiving burst data (Spontaneous COS messages) and RTU
events - i.e. transmissions initiated by the field RTUs. This feature almost eliminates the need
for the SCADA application to poll data since every change in one of the telemetry field
variables can immediately be transmitted to the SCADA application.

MOSCAD System - RTU definitions

To make the MOSCAD field system definition transparent to the SCADA client application
and to correctly parse the data received from the MOSCAD system, the API builds an internal
data structure defining the types and numbers of the field RTUs. To do so, it uses two external
system definition files (in ASCII format).

This automatic system definition done by the API routines hides the field system structure
from the SCADA application and eliminates the need for any application modifications when
working with different MOSCAD systems. Moreover, new RTUs can be added to the system
at run time using the appropriate API routine.

Primary/Secondary Gateway Modes

The IP Gateway supports a redundant configuration. There are two modes of operation:
Primary and Secondary. The initial mode of operation is defined by the startup process of the
IP Gateway. At any other time, the SCADA can change the mode of operation flexibly by
calling the appropriate API set mode routine. The API also supplies a routine for checking the
current mode of operation. This functionality of the IP Gateway provides redundant gateway
operation, which minimizes the risk of communication failure.

2-8

System Overview

Communicating with the IP Gateway

Once a channel has been established with the IP Gateway, the SCADA interface can issue
requests to the IP Gateway. The request categories are Send routines, Receive routines, Data
Analysis routines and Management routines.

Typical API sequence calls are the following:
Connect /* Establish Connection to Gateway. */
Poll /* Send a polling request. */
Receive /* Receive MDLC communication (answer) buffer. */
Get_next_message /* Extract one message from the MDLC communication buffer. */
Get_next_data_entity/* Get one data entity from the message buffer. */

Troubleshooting

The IP Gateway handles the communication with the SCADA in the REQMNG device.
Diagnostics on this device can help when troubleshooting the SCADA connectivity.

For more information on the REQMNG device, see the Software Diagnostics Output section.

MOSCAD NFM System

A typical network management system can be divided into three main levels:

• Network Management Level

• Element Manager Level

• Element Level

The following section provides a brief description of the MOSCAD NFM components that
allow managing and supporting these network management levels.

Figure 2-6 shows a typical MOSCAD NFM configuration including all network management
levels. It describes the MOSCAD NFM architecture that includes NMC computers and
workstations that monitor and control - via the IP Gateway and the NFM RTUs - non-SNMP
devices at the communication sites.

In this configuration, the end devices at the communication sites serve as a NE (Network
Element) and the NFM RTU serves as an Element Manager that monitors and controls multi­communication and environmental devices at the site. The IP Gateway allows monitoring and
controlling devices - via the NFM RTU - that are installed at multiple communication sites.
The NMC allows monitoring and controlling of all devices in the network via multiple IP
Gateways.

System Overview

The NMC application can use the SNMP protocol and the IP Gateway MIB to Auto-discover
the IP Gateway, the communication sites as well as the devices and their objects.

By using this MIB, the NMC application can poll the devices and their objects (NEs and their
objects) in order to refresh its database and to display unsolicited events (Traps ) in the Alarm
Manager application. By using the TELNET application in the host, the operator can access
via the IP Gateway and the NM RTU any communication devices that have an RS-232 port
with interactive interface.

The MOSCAD NFM product can be integrated either with the Motorola PRN (Private Radio
Network) architecture or with a third party communication/telecommunication system via an
IP Gateway that gives the NMC applications access to the equipment and environmental
devices at the sites.

MOSCAD RTU

The MOSCAD RTU is a smart modular unit designed to operate as a stand-alone controller or
as part of a system having any number of RTUs, control centers and sub-centers connected
through a communication network with any number of links and nodes.

The MOSCAD RTU must be configured and loaded with the appropriate application using the
MOSCAD Programming Toolbox.

The MOSCAD RTU is a microprocessor-based unit, which basically consists of a CPU
module and various I/O and communication modules. A wide range of I/O and communication
modules makes the MOSCAD system flexible to meet most application requirements.

For further details on the MOSCAD RTU, refer to the MOSCAD Owner’s Manual and the
MOSCAD Service Manual.

MOSCAD Toolbox

The MOSCAD Programming Toolbox software package allows the system engineer to define
and maintain the MOSCAD system according to user needs and requirements. The following
main functions may be performed by means of the MOSCAD Programming Toolbox:

System Overview

1. Editing the RTU user program including the following:

• Site Configuration according to hardware and port configuration

• Network Configuration according to network configuration

• Application database

• Application process

2. Preparing project documentation for the user

3. Automatically creating a central file to be used later during RTU database creation in the
SCADA control center

4. Downloading Site Configuration to the MOSCAD RTU via the RS-232 port of the unit

5. Performing the following functions on any MOSCAD RTU either via local connection or
via the communication network:

• Uploading Site Configuration and related data

• Downloading Application Program and Network Configuration

• Real-time symbolic (graphic) monitoring and debugging of the application (both

database and process)

• Updating time and date at RTU sites

2-12

System Overview

• Testing all hardware modules, including software calibration of analog inputs and

outputs

• Retrieving time-tagged events (of down to 1mSec resolution) logged in the RTUs

• Synchronizing the RTU real-time clock

• Retrieving errors logged in the RTUs (hardware or software malfunctions)

• Capturing the data packets on the communication links and analyzing the protocol

seven layer

• System software diagnostics by object entity names

The definition of the RTU application program allows the system engineer to build the RTU’s
database in a tabular form as a set of tables. The same tables used for the RTU database
definition are the basis for process programming, I/O link definition, automatic central
database definition, real-time monitoring of RTU operation, etc.

Once the database is built, the RTU programming process is carried out by using the symbolic
Motorola Advanced Ladder Diagram Language.

IP Gateway for TCP/IP

The IP Gateway hardware is based on the 68360 Motorola microprocessor, which is a smart
CPU with Ethernet and an I/O controller. It includes support for TCP/IP over an Ethernet port
(10Base-T and AUI connectors) for communication with the SCADA, and three serial ports
for communication with the Toolbox and with the MOSCAD RTUs.

The IP Gateway includes 22 LEDs, located on its front panel which indicate hardware status
and communication port activity. In case of a malfunction, see the Indication LEDs section in
the Hardware Installation section of this manual.

Two Ethernet connectors give support for connection to either a Twisted-Pair Ethernet cable
(via 8-pin RJ45 connector) or a Thick-Wire Ethernet cable (via 15-pin AUI connector). To
connect a Thin-Wire coaxial cable to the IP Gateway, a Thin-Wire to AUI connector unit
which allows connecting the coaxial cable to the AUI port, should be used (not supplied).

The IP Gateway software provides MDLC services to the SCADA
The MDLC application layer is used for receiving events, status and telemetry calculated data
from the MOSCAD RTUs to the SCADA
and process parameters from the SCADA central to the MOSCAD RTUs. The IP Gateway
software includes the TCP/IP driver for communicating with the SCADA computers and the
MDLC driver for communicating with the MOSCAD RTUs as well as with the MOSCAD
Programming Toolbox.

control center applications.

central applications. It is also used to send controls

2-13

IP Gateway Toolbox

The IP Gateway Toolbox is a software package, which runs on an IBM PC (or compatible),
and allows the user to build the configuration for the MDLC and TCP/IP drivers. It also
enables the user to download it to the IP Gateway hardware.

The IP Gateway Toolbox features the following:

• Microsoft Windows Man Machine Interface (MMI).

• Graphical User Interface (GUI). Each Toolbox module is represented by an icon, enabling

friendly user access.

• Receiving errors logged in the system from the IP Gateway and the RTUs.

• Receiving communication diagnostics from the RTUs and operation diagnostics from the IP

Gateway.

• Setting IP Gateway or RTU time and date.

• Downloading of user selected definitions/configurations to the IP Gateway.

• Erase Flash and System Download – enables the user to erase and download specific

system partitions.

System Overview

• Links Configurator – enables the user to change the number of links assigned to each

medium.

The IP Gateway Toolbox allows the user to set, modify and download the following four basic
groups of parameters:

• TCP/IP driver (IP address)

• IP Gateway configuration (IP Gateway Site ID and Link ID)

• MDLC Network configuration (system-wide MDLC routers)

• MDLC Sites Table (system-wide Site ID and Link IDs)

IP Gateway Web Server

The IP Gateway, version 4.0 and higher, includes a built-in Web Server. The Web server
enables users to perform certain Toolbox operations and to convey site information to and
from the technicians, regardless of where they are located, over the World Wide Web.

The IP Gateway Toolbox utilities available through the Web Server enable the user to
remotely perform the following operations:

• Provide reports on the status of each device in the current IP Interface or Gateway, as well

as historical and statistical data on the device activities.

2-14

• Remotely define SNMP and Motorola SSC parameters.

• Erase the IP Interface/Gateway Flash memory and downloads a new system.

IP Gateway Redundancy

To minimize the risk of a SCADA control center single point of failure and to ensure high
availability for its applications, a redundant IP Gateway can be configured. When one
IP Gateway is not available, a second, redundant IP Gateway can be used. To increase the
availability of the LAN network, dual Ethernet segments can be used, and each IP Gateway
can be connected to a different segment.

In a redundant IP Gateway system configuration, one IP Gateway acts as the primary unit.
The primary IP Gateway communicates properly over MDLC communication and over the
SCADA channels. There is bi-directional transfer of both SCADA application messages and
IP Gateway management messages. The secondary IP Gateway transfers IP Gateway
management messages only. (It does not send or receive any MDLC messages, since it is
logically disconnected from the link.)

System Overview

HealthCheck Mechanism

The IP Gateway system includes a HealthCheck mechanism which manages the MDLC
connectivity to the sites. Associated with each site are two links, through which the site can be
reached. A background mechanism in both the IP Gateway and the MOSCAD units constantly
verifies which links are available.

The HealthCheck mechanism uses the site table as the basis for its operations. As the
IP Gateway identifies which links are available, it can reduce communication overhead by
routing frames destined to sites through their operational links.

Communication Ports

The IP Gateway includes support for TCP/IP over 10 Mbits/sec Ethernet LANs for
communication with the SCADA, and three serial ports for MDLC over various links (radio,
dialup and dedicated lines, multidrop wireline, serial RS-232 or RS-485) for communication
with the MOSCAD RTUs.

The IP Gateway supports multiple logical channels running the TCP/IP protocol over
Ethernet, thus allowing multiple processes running on the SCADA computer, to
simultaneously access a number of functions in the IP Gateway.

The IP Gateway software supports four communication channels that can be configured to
support the following links:

Port 1 A - Ethernet - 8-pin RJ45 connector, twisted-pair (TP)
Port 1 B - Ethernet - 15-pin AUI connector
Port 1 C - RS-232

Port Specifications

Ethernet Port

Ethernet is a local area network (LAN) that allows the IP Gateway to communicate with
various computers and workstations at 10 Mbps. The connectivity of the IP Gateway to the
LAN infrastructure can be either twisted-pair, thick or thin-wire (coaxial) cable.

The IP Gateway includes two types of connectors for connection with the Ethernet port: AUI
and 10BaseT. Use either an RJ45 or AUI connector to connect your IP Gateway via either port
1A or port 1B, to Ethernet LAN.

3-7

Use the “Thin-Wire to AUI” unit for connecting the IP Gateway to “Thin-Wire LAN” (coaxial
media.

A unique Ethernet port address is assigned by Motorola at the factory. This address is on a
sticker, placed on the Gateway main board (but you don’t need to know it to run the Gateway).

The IP address for the IP Gateway should be assigned by the network administrator and has to
be set via the IP Gateway Toolbox. Like the Ethernet address, the IP address should be a
unique number.

IP Gateway Toolbox Port

Connect Port 2B of the IP Gateway to the IP Gateway Toolbox. Use the FLN6457 adapter to
connect the PC serial ports (COM1 or COM2) to the Gateway.

Figure 3-5: IP Gateway Toolbox Connection
If the RS-485 port (Port 2A) is required for communication with the field, use Port 3 for the

connection with the IP Gateway Toolbox. To introduce this change, connect the IP Gateway
Toolbox to Port 2B and use the Site Configuration program to change the default
configuration. Port 2A will now serve for communication over RS-485 with the field, and Port
3 will serve for communication over RS-232 with the PC.

After downloading the new configuration, you can use the IP Gateway Port 3 for connection to
the IP Gateway Toolbox (PC Port, COM1/COM2).

Always use Port 2B in order to erase and download a new Gateway software version (CODE)
or to erase and download the default configuration (CON) via your PC. Use this port also to
download a new Gateway configuration to your updated Gateway software, via your IP
Gateway Toolbox.

RS-232/RS-485 Communication Ports

For various radio or line communication configurations, first install the designated plug-in
board on Port 4 and run the Site Configuration program from your IP Gateway Toolbox in
order to configure the proper plug-in board.

Port 2B

Use an RS-232 MOSCAD cable, FLN6457A, to connect the IP Gateway (Port 2B or Ports 3
or 4) to the MOSCAD CPU.

Use an RS-485 MOSCAD Cable, FKN4400A, to connect the IP Gateway via Port 2A to the
MOSCAD CPUs for communication with the MOSCAD environment.

IP Gateway Toolbox

General Concept

The Windows-based IP Gateway Toolbox software which is delivered with the IP Gateway
unit, allows the system engineer to define and maintain the IP Gateway parameters. For
communication over the IP network, the IP Gateway requires that a unique Gateway IP address
be set, as well as other optional TCP/IP parameters. For communication with the MOSCAD
RTUs, the IP Gateway requires that the type of the communication links be selected, as well as
the routing topology and other optional MDLC configuration parameters.

When you start the IP Gateway Toolbox, the main IP Gateway Toolbox screen appears with
the following icons:

Each icon represents a program that allows you to define, modify and save the sub­configuration or to retrieve diagnostics reports from the Gateway.

5-1

Site Configuration

The IP Gateway system operates with a very wide range of communication boards which
satisfy most application requirements. To make the system operation more efficient, the
configuration of the IP Gateway unit should be defined. Site configuration involves the
following:

• The ports of the IP Gateway and their parameters.

• Site ID (logical address) and system address.

• The IP Address of the IP Gateway

Once the configuration is downloaded to the site, it is ready to communicate with the devices
connected to its ports (Computer, RTU, Terminal Server, etc.).

Note: CPU modules received from the factory are configured to the default configuration.

Site Configuration Window

The Site Configuration window allows you to define, modify, and save the IP Gateway ports
and their parameters. To start the Site Configuration tool, double-click the Site Configuration

icon

in the IP Gateway Toolbox folder. The following will appear:

5-2

ToolBar

The Toolbar displays the icons described under Icons.

SiteIDBar

The SiteIDBar is used to specify the IP Gateway to which the site configuration will be
downloaded and from which a site configuration can be uploaded. For SiteIDBar parameters,
see the Download and Upload commands.

• Make sure that you have opened the correct configuration file - the one that contains

the configuration for the IP Gateway you are communicating with. Use the Open
command to open a configuration file.

5-11

Site Configuration

• Ensure that the OutPutBar is displayed.

• Ensure that the SiteIDBar is displayed and the address is configured properly.

• Ensure that the ToolBox computer is ready to communicate.

Use the SiteIDBar to specify the IP Gateway to which the site configuration file is to be
downloaded.

SiteIDBar parameters

Local

If the ToolBox computer is locally connected to the IP Gateway, make sure that this parameter
is selected. Note: New site ID (default=1) will be used.

Remote

If you want to configure a remote site, click this parameter.

Site ID, Link ID

If you want to configure a remote site, specify its Site ID, open the Link ID drop-down list and
select the appropriate link ID.

New Site ID

To specify a new site, change the site ID and the system address of the IP Gateway. Enter the
appropriate values in the Site ID field. The default is 1.

The site ID defines the unit’s logical address, and it may range from 1 to 65,287.

System Address

To specify a new site, change the site ID and the system address of the IP Gateway. Enter the
appropriate value in the System Address field. The default is 0.

The system address is the physical base address assigned to the whole system, and may range
from 0 to 65,535. The base address is used in broadcast transmissions.

The physical address of each IP Gateway is automatically allocated by ToolBox and by the
control center in the form of <system address> + k where k is the logical address (Site ID) of
the unit. For example, if the system address is 100, then the IP Gateway addresses may be 101,
102, …, 100+n. If two systems share the same communication radio (over one frequency) and
the first system contains N sites, then the system address of the second system must be defined
as N+50 (50 addresses reserved).

After specifying the IP Gateway in the SiteIDBar, click on the Download icon or select
Download from the File menu. The ToolBox will ask you to specify the communication
password. After the correct password is entered, ToolBox will begin downloading the
configuration file. The download information and status will be displayed in the OutPutBar
Download Tab. At the end of the download operation, the IP Gateway will perform a cold
restart and build the software object entities according to the user’s definitions. Once a unit
has been reconfigured and restarted, the port used for configuration may no longer be defined
as RS232 Local Computer port. In this case, connect the ToolBox to another port, defined as
Computer port, in order to proceed with your work. For a local connection to the ToolBox,
there must be at least one port defined as RS232 Local Computer port.

5-12

Upload

Site Configuration

If none of the ports is defined as RS232 Local Computer, ToolBox access will be permitted
through any port, provided it is defined as MDLC. If there is no such port, access will be
denied. You may reset the configuration of the IP Gateway using the 'Erase Configuration'
operation in the Downloader application.

The Upload command is used to read the site configuration from the IP Gateway into the
ToolBox. You can upload from the IP Gateway directly connected to the ToolBox computer,
or from a remote IP Gateway.

Before you activating the Upload command:

• Make sure that the OutPutBar is displayed.

• Make sure that the SiteIDBar is displayed and the address is configured properly.

• Make sure that the ToolBox computer is ready to communicate.

Link Layer Parameters for DataTAC Port 1

This section reviews the parameters through which you can control the functioning of the Link
Layer.

Link type [Standard]:

Not supported yet. Select the Standard link type to establish a link that requires ACKs.
Otherwise select Fast Link (no ACK).

5-30

Site Configuration

TX queue size <2^3-2^9> [2^6]:

This is the maximum number of MDLC frames that can be placed in the transmission queue
before a transmission process starts.

Number of ACK buffers <5-50> [40]:

The reception process of the Data Link layer prepares an ACK for each received data frame,
and is capable of issuing, in a single ACK message, up to 57 ACKs for data frames that arrived
in uninterrupted sequence. This parameter determines the number of ACK buffers in which
ACKs are prepared and moved to transmission before the “Cannot get ACK buffers” message
is issued to the Error Logger. This message means that the acknowledging side is unable to
move to ACK transmission because of heavy reception traffic, or because it cannot access a
channel for transmission.

Number of TX retries <0-9> [2]:

The number of times the Data Link layer retransmits a data frame for which ACK was not
received.

Number of TX retries upon BUSY ACK <0-9> [2]:

The number of times the Data Link layer retransmits a data frame for which BUSY ACK was
received (BUSY ACK is issued when all Data Link layer boxes of the switching node on are
full).

Interval between TX retries upon BUSY ACK <10-100> *100mSec..... [40]:

The interval of time that should elapse before a data frame for which BUSY ACK was
received, is retransmitted.

Number of TX broadcast (Group call) retries <0-9> [0]:

The number of retries for broadcast frames. Since broadcast frames are not acknowledged,
specify a value greater than 0 to increase the chances of the frames reaching their destination.

A broadcast that activates a momentary operation (not latch!) is likely to reactivate the
operation if the number of TX broadcasts is greater than 0.

Interval between broadcast (Group call) retries <10-100>*100mSec [40]:

The period of time that should elapse between retries of broadcast frames (if the previous
parameter is not 0).

Force 'Local response' [Force]:

It is possible to conduct a session based on Site ID/Link ID using Local if the port is of
Computer/Rslink type. Normally the port is defined for Local Response if the medium is not
“multidrop”. In any case, “local response” can be forced on a port if it is not “multidrop”. The
default value is based on the port type. It is recommended to leave the default as is.

Clock synchronization delay <0-250> mSec [100]:

The delay (applied to the channel) between the end of a transmission and the beginning of
reception, for clock synchronization purposes. The default depends on the selected medium.
However, the user can change it.

5-31

Site Configuration

Max. number of addressable sites in a transmission <1-4> [4]:

Maximum number of units the Data Link layer is capable of addressing in a single
transmission. For “private conversation”, specify 1.

TX to failed RTU <0:DISABLE 0-30> Min [5]:

A period of time after which a failed link will be considered as being back in order, provided
the value of the next parameter (“Periodic check...”) is Disable. Or, the period of time after
which the Network layer issues a control frame to check the link, if the value of the next
parameter is Enable.

Periodic check of failed RTU [Disable]:

The valid values are:

Enable Network will send a control frame in order to check whether the link is still in

“failed” status. The frame is issued if the link has been in “failed” status for the
period of time specified in the previous parameter.

Disable The link is considered to be back in order after the period of time specified in the

previous parameter.

Interval between FULL DUPLEX TX retries <10-100> *100mSec [80]:

The period of time that should elapse before a retry takes place in Full Duplex. New data
frames cannot be sent to the retried unit.

5-38

Advanced Parameters

This section reviews all of the ToolBox advanced configuration parameters. Throughout the
ToolBox, advanced parameters are displayed according to context. For example, when you
click the Advanced tab in the WorkSpaceBar in Site Configuration, ToolBox shows only those
parameters that are applicable to the selected configuration. For details on opening the
Advanced parameters windows, see WorkSpaceBar Advanced Tab.

Some of the parameters listed here are applicable to the new version only. If you open an older
configuration file and decide not to change the version, ToolBox grays (hides) those
parameters that cannot be used in that version.

For each parameter, ToolBox dialog boxes provide three values: the minimum, the maximum
and the default. The range is specified between < > symbols. For example, <1-200> means that
the value can be a number between 1 through 200. You can specify a value greater than the
maximum value, in which case the system only issues a warning message. Exceeding the range
may consume additional memory and may cause unexpected or incorrect behavior in the RTU.

The default is automatically entered in the parameter field and appears between square
brackets (for example: [80]). You can change this value.

Site Configuration

The default value provided in the parameter specifications below, is one of the possible values.
The default changes according to Port Type.

Physical layer

This section reviews the parameters through which you can control the functioning of the
Physical Layer.

Number of idles to announce 'End of RX' <1-200> [80]:

In UART communications without a channel access mechanism, a period of silence notifies all
layers above Physical that reception has ended. This period is calculated in terms of idles
which are converted to time as a function of the data speed. The system uses this value or the
value specified in the second field (and NOT more...), whichever is the smallest.

The value is equivalent to the time required to receive 1.5 frames (as defined in the MDLC
advanced parameter Unformatted adapter buffer size). The system uses this value or the value
specified in the second field, whichever is the greatest.

The parameter has no meaning when a channel access mechanism is used (such as RS-485 and
Darcom radio).

Interval between Link TX retries <100-6000> [500]:

The interval of time that should elapse before a data frame for which no ACK was received, is
retransmitted.

and NOT more than <10-2000> mSec [500]:

Number of bits for staggering <2-8> [4]:

This parameter is related to the slotted access mechanism used by the channel access sub-layer
of MDLC. A value of n means that an RTU will wait at most 2

n

free slots before transmitting.

5-39

Site Configuration

Max. time waiting for TX-grant <100-900000> mSec [900000]:

Max. TX-data duration <1000-60000> mSec [30000]:

The maximum time during which data can be transmitted. After this period of time
transmission stops even if it has not yet ended.

Channel-holding tail <0-1000> mSec [0]:

The period of time during which the PTT should be held pressed at the end of data
transmission or between frames. Enter 0 to ignore this feature.

Busy-channel TX-override delay <0-30000> mSec [0]:

The maximum waiting time for a channel. After this time-out, the system accesses a channel
whether or not it is free.

TX-warm-up time <10-1000> mSec [200]:

The period of time during which the PTT should be held pressed before a predetermined
preamble is transmitted and before data transmission begins.

Disconnect time <100-500> mSec [200]:

In a trunked system, the period of time that should elapse between releasing the PTT and until
the radio is ready for reception.

Channel request PTT active time <500-1000> mSec [500]:

In a trunked system, the maximum period of time during which the PTT should be held
pressed in order to access a channel.

Channel request cycle time <5000-10000> mSec [5000]:

In a trunked system, the PTT pressing time cycle until a channel is accessed.

Channel monitor time resolution <10-1000> mSec [0]:

The size of a time slot in the slotted channel access mechanism of MDLC.

TX-holdoff time <0-30000> mSec [0]:

This is the minimum period of time during which a channel must be free before transmission
can resume. If another unit transmitted during this time, the current unit does not have to hold
transmission.

Minimum time to retry Time <0-30000> mSec [0]:

The minimum period of time that should elapse between the end of a transmission and its first
retry, and between retries.

Pulse Dialing 'break' time <60-70> mSec [61]:

In pulse dialing, the ON (“make”) and OFF (“break”) times should be defined. This parameter
defines the OFF time.

61 US standard

5-40

Site Configuration

67 European standard

Hanging up an unused line by INITIATOR after <1-60> Sec [20]:

A period of quiet time at the end of which the initiator of the conversation hangs up the phone.

Hanging up an unused line by RESPONDER after <1-120> Sec [120]:

A period of quiet time at the end of which the responder hangs up the phone.

Number of dial retries <1-10> [3]:

The number of times the number will be redialed (in addition to the first time) in order to
establish communications with a unit.

Interval between retries <1-30> Sec [7]:

Interval of time between a failure to establish communications (BUSY, NO ANSWER) and
the next dialing. However, if a line is busy and another line is available, the attempt is renewed
through the other line without delay.

Number of rings for answer <1-255> [2]:

Number of rings to wait for the called party to answer.

Wait for data carrier <1-255> *100mSec [250]:

A waiting period between the end of dialing and the reception of the connection signal from
the answering modem. After this period, the attempt is considered to be a failure.

Lost carrier to hang-up delay <1-255> *100mSec [20]:

The period of time during which disconnection is delayed after the carrier is lost.

Wait for dial tone <1-255> *100mSec [50]:

The amount of time the calling device should wait until it gets the dial tone.

Wait time after hang-up <1-255> *100mSec [35]:

The minimum time that should elapse between two attempts to obtain a line.

Number of dial tone retry <1-20> [3]:

Number of retries to obtain a line.

Blind dialing [NO]:

The valid values are:
NO Wait for the dial tone

YES Dial after a pre-defined period of time (blind dialing).

HDLC 'RTS' control [AUTO]:

The valid values are:
AUTO RTS runs automatically before the transmission and terminates after the

transmission

5-41

Site Configuration

ON RTS is always ON.
This parameter is for old boards that do not react fast enough to RTS.

Minimum number of flags between HDLC frames <0-15> [0]:

Number of HDLC flags between frame transmissions. For old OEM equipment, specify a large
value.

Minimum TX time <0-2000> mSec [1000)]:

Minimum transmission time. If the actual data transmission takes less than the specified value,
the unit will continue to transmit until this time elapses. Smartzone trunked systems work
more efficiently with a minimum TX time of 1000 mSec. Specify 0 to ignore this parameter.

Time before long warm-up <0-3000> mSec [1600]:

In Smartzone trunked systems, this parameter specifies on channel/free channel condition
which, if exceeded, requires a longer warm-up. Specify 0 to ignore this parameter.

Long warm-up <0-2500> mSec [1000)]:

If a positive value was specified in the previous parameter, specify here the long warm-up
time. 1000 is advisable in Smartzone.

Time resolution in control channel <50-1000> mSec [50]:

In a trunked system, this parameter specifies the size of a time slot when the radio is on the
control channel.

First warm-up delay <10-2500> [350]:

This field defines the delay (in msec) from the moment that PTT has been pressed until data
transmission starts on the first time in a session.

Tx Hold off time <0-10000> [0]:

The minimum interv al between two consecutiv e transmissions of data (not relevant for
acknowledgment messages).

Consequent warm-up delay <10-2500> mSec [350]:

This field defines the delay (in msec) from the moment that PTT has been pressed until data
transmission starts, on subsequent sessions (after the first; see previous parameter). The value
should be greater than the First Warm-up Delay, because the first time the Trunking system
perfoms part of the warm-up by itself.

Channel monitor time resolution <10-2500> mSec [200]:

Defines the interval from the moment PTT has been pressed in an RTU until the other RTUs
sense it. This interval depends on the type of the radio used – the quicker the channel monitor's
response, the shorter this interval. The RTU uses this parameter to prevent collisions on the
channel when several RTUs have messages to transmit by contention.

This interval is used (automatically) as follows: each RTU is assigned a priority level as a
function of the data message it wants to transmit (new data, acknowledgment, retry, etc.) and
in some cases, as a function of its address. When the RTU wants to transmit that message, it
first checks whether the communications channel is free or not. If the channel is free, the RTU

5-42

Site Configuration

will start transmitting only after a delay that is equal to this parameter multiplied by the RTU's
priority level. If in the meantime the channel has been taken by a higher-priority RTU, the
whole process is repeated when the channel is free again.

For example, let's assign the time resolution T. When the RTU accesses the channel, it starts
transmitting only after a delay that is a factor of T. When the RTU accesses the channel for the
first time, the delay is (n+4)×T, where n represents the 4 less sig nificant bits in the address. When
an RTU sends an acknowledgment to another R TU, it w ill start transmitting only after a delay of
0 to 3T. If a collision occurs because two RTUs have been addressed with the same 4 less
significant bits, then the address bits are shifted automatically, and the RTU starts transmitting
after a different delay.

Channel monitor override delay: <0-3200> 100 mSec [0]:

Defines the delay after which the RTU will transmit its message even if the communications
channel is busy. The default value of 0 means that this feature is disabled (i.e., the RTU will
not transmit if the channel is busy).

Data repeat mode: <Yes / No> [No]:

Not used.
For future use. To implement the store and forward feature by hardware. It is applicable in

case the piggyback modem is DFM, FSK, or COS.

Minimum time to retry: <0-2500> mSec [0]:

The minimum time (in msec) that the RTU will wait before retransmitting an unacknowledged
message.

Link Layer

This section reviews the parameters through which you can control the functioning of the Link
Layer.

Link type [Standard]:

Not supported yet. Select the Standard link type to establish a link that requires ACKs.
Otherwise select Fast Link (no ACK).

TX queue size <2^3-2^9> [2^6]:

This is the maximum number of MDLC frames that can be placed in the transmission queue
before a transmission process starts.

Number of ACK buffers <5-50> [8]:

The reception process of the Data Link layer prepares an ACK for each received data frame,
and is capable of issuing, in a single ACK message, up to 57 ACKs for data frames that arrived
in uninterrupted sequence. This parameter determines the number of ACK buffers in which
ACKs are prepared and moved to transmission before the “Cannot get ACK buffers” message
is issued to the Error Logger. This message means that the acknowledging side is unable to
move to ACK transmission because of heavy reception traffic, or because it cannot access a
channel for transmission.
