FAST/TOOLS has been developed with over 40 years of experience by combining our expertise in Supervisory
Control And Data Acquisition (SCADA) with requirements from users and industry leaders. The FAST/TOOLS package
is a powerful, modern, exible, distributed operations information and control software package. It implements a
Web-based supervisory control human machine interface, OPC server/client functions, data acquisition from a variety
of controllers and devices, alarm management and historical data management. Furthermore it is a leading system
package for operations control and information integration with business systems and is available on a wide range of
industry standard operating platforms. Many industries and utility companies with a need for data integration and data
integrity use FAST/TOOLS from Yokogawa in their applications. FAST/TOOLS is also successful in critical applications
due to its very reliable design, support of redundant and nonstop systems and its on-line conguration capabilities.
These properties contribute to high eciency and high quality production processes. FAST/TOOLS is also highly
scalable, it can easily grow with the client’s needs, both in the short and long term, avoiding premature obsolescence.
As is hardware independent, it is widely supported by standard operating systems, standard network protocols,
standard user interfaces, and standard software development tools.
FAST/TOOLS provides solution possibilities in a wide range of control execution applications with the following
characteristics:
• Multiple Process Site environments
• PLC/RTU based control systems
• Wide area communication
• Intensive (mission critical) control performed by subsystems
• Relatively high content sequential (logic) control
These characteristics are often seen in for example Oil & Gas production and transport, infrastructure, utilities
monitoring and control and high performance manufacturing applications. It also allows the flexibility of combining
different types of systems to provide hybrid solutions, both on new and existing sites (green and brown field
development).

FAST/TOOLS is a user orientated environment. Information ows and architectures have been designed
with information availability in mind. It supports a user environment based on web technologies and can
be easily extended with new applications through the use of open interfaces. Secure login and role-based
authorization mechanism ensures that information is only available to the appropriate users.
Applications and process information can be rapidly deployed and easily maintained centrally on the
server. This so called “zero deployment” means that client applications can be start from any web-browser
and the users get the application. There is no need to manage licenses. Benets include faster application
deliveries increased IT productivity, and widely accepted technology.
Other benets of a user environment are:
• Information can be accessed anywhere an Internet connection is available.
• The information is ‘real-time’ (no waiting time for critical information).
• The information is more secure than it would be on a personal computer.
• Upgrades containing new functions and enhancements are free and automatically deployed there is no need to
manually install software or license keys.
Today Web-technologies are used more and more. Instead of specic client programs, Web browser
environments become a user interface, a HMI, to an application (see gure below).
The FAST/TOOLS Web HMI consists of a Web HMI Server and a Web HMI Client component that can either run
separate from the FAST/TOOLS Server or be installed altogether with the FAST/TOOLS Server environment on a
standalone node. Installing the Web HMI Server on a separate node has the advantage that load can be shared
between the FAST/TOOLS Server and Web HMI Server.

For 24/7 operator stations, both Web HMI Server and Client are advised to be installed and maintained on the same
machine as represented in the centre of the gure above.
Beyond traditional system software distributions, cloud computing & virtualization infrastructures are fully supported by
the FAST/TOOLS software platform.
FAST/TOOLS is comprised of function specific software modules (specified in the table below) that connect to the
communication data bus BUS/FAST. All FAST/TOOLS modules are event based and submit their events to BUS/
FAST. BUS/FAST passes these events in a highly secure and reliable manner to modules that are subscribed to these
events. The result is a very low CPU-load on any system during normal operations.

The full FAST/TOOLS functionality can be installed on one system (stand-alone configuration) or distributed over
many (dispersed) systems (distributed configuration). The minimal configuration of any FAST/TOOLS system is a
standalone system with the following modules installed:
• BUS/FAST
• ITEM/FAST
• DATABASE/FAST
• EQUIPMENT/FAST
• ALARM/FAST
• PROCESS/FAST
• USER/FAST
Additionally any of the other modules can connect to the bus in order to enhance the functionality of FAST/TOOLS.
In addition to the software modules FAST/TOOLS defines four functional components within its software & system
architecture which may be distributed across geographical dispersed locations to adapt to any specific application
requirements:
FunctionDescription
SCADA Server
Web HMI Server
Web HMI Client
Each FAST/TOOLS system comprises at least one SCADA Server, one Web HMI Server and one Web HMI Client
component. These may be configured as a stand-alone or distributed system. The following table provides an
overview of which of the specific FAST/TOOLS software modules are installed on each functional system component:
*1: The Web HMI Client only requires a standard supported OS and a Web browser (See System Requirements). Only one
time communication conguration to setup and by any new update new version of the Web HMI is available on the server.
The SCADA Server is the core processing unit of the system. Within a distributed conguration it manages sets of
data such as control objects (tags) and takes care of gathering data from the attached equipment in any distributed
or stand-alone conguration.
A Web HMI Server delivers an operation and monitoring window (HMI) of data & information gathered and
processed by SCADA servers to Web HMI Clients.
A Web HMI Client accesses a W eb HMI Server to display process mimics, trends, alarm & events and other
operating data. Furthermore each Web HMI client accommodates a full functional application engineering
environment for both database and display conguration. A Web HMI Client can run on the same computer as its
Web HMI Server or on a dierent computer across LAN/WAN networks.
The table below shows the scalability and specifies the dimensional limits of FAST/TOOLS based systems.

FAST/TOOLS has a true client/server architecture, which is not limited to stand-alone stations, and allows for
distributed functionality.
Where system availability is a prime issue FAST/TOOLS can be configured to run in a redundant configuration.
Several redundancy concepts are available as a standard, illustrating the flexibility of FAST/TOOLS. Examples are
dual or triple server configurations, redundant networks between the SCADA system servers and clients and/or
between SCADA system servers.
FAST/TOOLS supports at least any combination of the following architectures within the specified system dimension
limits (see the SYSTEM SPECIFICATION section above).
Stand-alone Concept

The ‘Stand-alone’ concept is based on running the complete SCADA data acquisition, supervisory control, engineering
and operations environment on one computer. In terms of licensing this requires only one Windows based SCADA
Server package (sized to the required number of items for its application). With reference to the ‘Models and Suffix
codes’ section in this GS document the minimal license requirement for this architecture – assuming only the
standard driver package for field I/O communications is required – is:

This type of configuration may be used for relatively small applications where it is acceptable to have only one
combined Server/HMI station for both operator supervision and engineering.
The ‘Remote Web HMI Server/Client’ concept allows for more scalability. It is based on running the SCADA data
acquisition, applications and real-time database environment on a dedicated heavy duty SCADA server while running
the engineering and operations environment on one or more dedicated operator/engineering computers. In terms of
licensing the configuration as visualized above requires one Windows, Unix or Linux based SCADA Server package
(sized to the required number of items for its application) and two Web HMI Server packages (including one client).

This type of configuration may be used for fairly large applications with many RTU/PLC stations randomly located
(possibly at long distances) around one central location.
The ‘Remote Web HMI Client’ concept allows for enhanced HMI flexibility and negligible cost for maintaining remote
clients across geographically dispersed locations. It is based on running the Web HMI Server on a dedicated computer
serving its associated remote Web HMI Clients. These Web HMI Clients can be easily deployed on any computer
device at any location over LAN, WAN and VPN networks. License registration is not required (zero deployment),
and is initiated through a standard supported Web browser. In terms of licensing the configuration as visualized
above requires one Windows or Linux based SCADA Server package (sized to the required number of items for its
application) and one Web HMI Server package (including three client). With reference to the ‘Models and Suffix codes’
section in this GS document the minimal license requirement for this architecture – assuming only the standard driver
package for field I/O communications is required – is:

This type of configuration may be used for applications when many ‘light’ and/or remote users need a real-time
window into the process and its SCADA environment.
The FAST/TOOLS Web HMI consists of a Web HMI Server and a Web HMI Client that can either run separate from
the FAST/TOOLS Server or be installed altogether with the FAST/TOOLS Server environment on a standalone
node. Installing the Web HMI Server on a separate node has the advantage that load can be shared between the
FAST/TOOLS Server and Web HMI Server.

The ‘Host to Host’ concept (see gure above) allows for loosely coupling two or more autonomous FAST/TOOLS
systems to exchange or synchronize ‘real-time’ data across independent system domains.
This type of conguration may be used for applications where several systems at a central or across dispersed
process locations need to be fully independent in terms of maintainability and operations, while at the same time
exchange key data with other (high level master) FAST/TOOLS SCADA Servers.
Secure Host to Host communication.
To support high levels of data and system security within FAST/TOOLS there is the possibility to encrypted host
to host communication as a second level of defense and security besides IT based services such as the native
integration with Active Directory Services. Communication encryption between two FAST/TOOLS Systems can be set
between two FAST/TOOLS nodes or between the RGS and one FAST/TOOLS node.
FAST/TOOLS Host to Host security is based on industry standards that are also used for secure communication on
the Internet, such as SSL, DTLS, TLS and public/private keys.
This provides an enhanced level of safety encrypted communication between the dierent FAST/TOOLS systems.
Encrypted network communication (AES-256) is supported for: Host Server, Web HMI Server, Web HMI Client and
Enterprise Servers connections.
For large scale geographically dispersed projects, there may be a hierarchy of individual Process Automation
Systems, which in turn are each responsible for a specic region, and are managed by a higher level system. For
these applications FAST/TOOLS provides a exible, scalable architecture for Enterprise Automation Solutions, by
supporting multi-level/multi-node congurations. It is possible to balance server functions over multiple machines, for
example for data acquisition or for supporting many HMI clients. This architecture lends itself very well to Enterprise
wide remote operations, - monitoring and - maintenance projects for dispersed production sites and supply chain
infrastructures such as oil and gas elds, pipeline grids, water distribution, energy generation, etc.
In ISA-95, the functional levels of an Enterprise Control system are dened. Note that the levels presented in
the sample architecture on the next page relate to a physical business model in which a company consists of a
headquarters, regional oces and local oces. All these locations can contain systems which together form the
Enterprise Architecture. This should not be confused with the automation levels dened in ISA-95, in which the logical
information layers of a control system are dened. In the Enterprise Architecture, four major levels are identied (see
sample architecture on the next page). Each level has its typical characteristics and usage.
Process level
The process level contains local DCS/SCADA/PLC systems or other automation control/monitoring equipment that
directly interacts with the process. As an example a typical large gas production platform that is controlled by a DCS
system and exchanging process information with the area level.
Area level
The area level supervises all processes within a graphical area to provide control over this area. It contains a
FAST/TOOLS server node that is connected to all DCS and/or SCADA systems at the process level. A typical
application at this level is to control the total amount of production within the area, and to supply production KPI’s.
Business unit level
The business unit level is typically responsible for all areas within the business unit. The business unit contains a
FAST/TOOLS server node that exchanges KPI’s and other process data with the Area level. At the business unit
level, users are expected to have access to data that is supportive in optimizing production of individual as well as
interrelated assets.
At the corporate level, all KPI’s and other process data of all the business units are collected and aggregated
providing a holistic view of the performance of the enterprise and its operational groups down to process level in
real-time.

The above sample of a typical Enterprise Architecture provides an impression of the exibility to compose t for
purpose enterprise wide automation system integrated architecture. This functionality is oered without compromising
on the autonomous operation of the individual server nodes that can directly serve information from all levels to a
single visualization environment.
FAST/TOOLS supports the following two redundancy schemes.
- High Availability Computing (HAC)
- Dual-redundant Platform for Computer
The following table shows the features for the both system.

*2: Depending on eld update frequency and data buer protocol support.
High Availability Computing (HAC)
FAST/TOOLS supports full communication and application redundancy, independent of applied communications
media and system server hardware. There are several features available in FAST/TOOLS for building high availability
system congurations combined with advanced guidance tools for some typical set-ups.
The Hot-Standby software module will take care of handling Dual, Triple, Quad or even Six redundant servers and
redundant hard drive congurations (RAID), independent of applied communications media, geographical distance,
dierent domains, and system server hardware. Additionally, watchdog and heartbeat functionalities will manage
which server is active and which server is standby and how and when to switchover to the standby server.
For HAC conguration all the servers must have the same Package including all the Server Package options.
For Triple, Quad or higher, please contact Yokogawa Global SCADA Center for details.

Hot Standby
F07E.ai
Figure Hot-Standby software Redundancy
Watchdog
This feature is only applicable for redundant server congurations. In this scenario one Watchdog process runs on
each of the redundant servers. A Watchdog takes a number of inputs relating to the health the ‘active’ system as
well as the current health of the ‘hot standby’ system. It decides whether the system is suciently healthy to carry
on, or whether the redundant server should be brought online.
The Watchdog takes the following inputs as a basis for determining the health of the system:
• Current FAST/TOOLS health
• Current state of the network connection to the partner server
• Availability of network devices
• Results of custom scripts
For redundant server pairs twice the package and all the Server Package options must be ordered.
The watchdog can support the following congurations:
• Up to 4 network interfaces
• Up to 20 IP device checks
• Provision for periodic checks using custom scripts as input to the health check
Active and Hot Standby
Once a redundant server combination is up and running, one server will be running FAST/TOOLS in its entirety,
whilst the other server will be running a minimum set of FAST/TOOLS functions sucient to monitor its own system
and its associated redundant counter part. The server that is running the full real-time FAST/TOOLS environment
is said to be the ACTIVE server and all SCADA functions will be handled by this machine. The other server that is
running the minimum set is said to be the HOT STANDBY server and does not provide any SCADA functions (Note
that only one server is allowed to be ACTIVE at any time).
Island situation
The ‘active’ server does not shut itself down in a bad health situation, but will be shut down by the ‘hot standby’
server. The only exception to this is when the server is in an island state. This means that the server detects that it
has no connection to the partner, no connection to any other network devices and so is isolated from the rest of the
world. In this case it has no connection to the eld and no-one to shut it down, so the server will shut itself down in
this case after a predened timeout.
Initial status
When the redundant servers are initially started they will always start up as a HOT STANDBY server. The servers
in a redundant conguration are of equal value, when the system starts initially and both servers are STANDBY the
server that has been assigned as the PRIMARY server will become ACTIVE and the other (SECONDARY) server
will remain in STANDBY mode.
Data synchronization
This mechanism secures - when one or the other server becomes active at any time - that the conguration and
information on both servers is constantly synchronized, so that when the HOT STANDBY server takes over it does
so with the latest conguration and information (mirror function).
FAST/TOOLS supports the Dual-redundant Platform.
The dual-redundant function consists of two computers which are regarded as a unit of “logical FAST/TOOLS” to
archive a SCADA function.
Those two units of the FAST/TOOLS server share an identical Ethernet address, which provides other servers
transparent accesses to the data without considering which one of the redundant server is active or not.
In the dual-redundant conguration, one of the two server is active and the other server is on stand-by. For
redundancy, the two units of the server are connected via a dual-redundant control network.
Only the active server downloads the engineering data and equalizes them to the stand-by server via the dualredundant control network.
When the active server fails, the active side automatically switches (i.e. fails over) to the stand-by server. Manual
“switch over” is also available.
The fail/switch over takes place in less than a second, thus the components (e.g. other server and subsystem
controllers) are not inuenced.
Yokogawa has limited the models of computers to be used for the Dual-redundant Platform for Computer. Contact
Yokogawa for more details of computer.

Web HMI Server/Client————
The FAST/TOOLS HMI is fully Web based and allows the operator to easily and intuitively navigate through the
operator displays in a browser-like environment. The HMI is designed for intranet deployment and delivers the benefits
of incorporating web technology.
Some of the main benefits are:
• Minimum specication of PC hardware
• Centralized administration of software installation and management
• Load sharing through remotely deployed displays and distributed client/server architecture
CDSS (Collaboration Decision Support Solution) facilitates a holistic view over all key aspects of a producing
company’s operations and can be utilized to monitor the main production facilities.
Mobile Client HMI from mobile devices like tablet computers, smart phones and tablets support HTML5.
ASPA (Alarm System Performance Analysis) Module for improvement the processes to avoid operator overload and
reduces the risk of critical alarms being overlooked.
The benefits for the operator are ease of use provided by the intuitive browser-like HMI standard that allows the
grouping of FAST/TOOLS data into logical categories such as process mimics, alarm and event views, historical and
real-time trending, faceplates and reports (which can be step less zoomed and panned in real-time). Furthermore the
process mimics can contain multiple dynamic layers and visibility groups which become active and visible depending
on user privileges, process conditions, zoom level, etc.
Although the FAST/TOOLS HMI is freely configurable to meet specific application needs the basic elements that can
be enabled as part of the operator environment for supervision and control are:
• Layout
• Menu
• Toolbar
• Status line
The FAST/TOOLS HMI menu and toolbar accommodates for advanced display navigation through browser history,
menu’s and direct display call-ups.
