WARNING: SOME EQUIPMENT MAKES USE OF LARGE CAPACITORS. HAZARD-OUS VOLTAGES ARE STILL PRESENT INSIDE CERTAIN ENCLOSURESFOR A PERIOD OF AT LEAST 5 MINUTES AFTER THE REMOVAL OFTHE HIGH VOLTAGE. USE A PROVEN VOLTMETER TO VERIFY THATVOLTAGE IS NOT PRESENT.

WARNING: VERIFY THAT THE MANUAL DISC BRAKES ARE RESTORED TO NOR-MAL SERVICE BEFORE OPERATING THE TRAIN ON THE GUIDEWAY.THE DISC BRAKES WILL NOT FUNCTION WHEN THEY ARE MANU-ALLY RELEASED.

WARNING: BEFORE DISCONNECTING HYDRAULIC LINES OR PERFORMINGMAINTENANCE ON HYDRAULIC COMPONENTS, ENSURE THATHYDRAULIC PRESSURE IS NOT PRESENT.

WARNING: BEFORE DISCONNECTING PNEUMATIC/NITROGEN LINES OR PER-FORMING MAINTENANCE ON PNEUMATIC/NITROGEN COMPO-NENTS, ENSURE THAT PRESSURE IS NOT PRESENT. BE AWARE

THAT RELIEVING LINE PRESSURE DOES NOT NECESSARILY RELIEVETHE PRESSURE DOWNSTREAM OF SOME CONTROL COMPONENTS.

WARNING: BEFORE DISCONNECTING COOLANT LINES OR PERFORMING MAIN-TENANCE ON COOLING SYSTEM COMPONENTS, ENSURE THATPRESSURE IS NOT PRESENT. BE AWARE THAT RELIEVING LINEPRESSURE DOES NOT NECESSARILY RELIEVE THE PRESSUREDOWNSTREAM OF SOME CONTROL COMPONENTS.

WARNING: THE LIQUID COOLING SYSTEM COMPONENTS AND COOLANT AREHOT. ALLOW SUFFICIENT TIME FOR THE EQUIPMENT AND COOL-ANT TO REACH A SAFE TEMPERATURE BEFORE PERFORMING ANY

MAINTENANCE TASKS.WARNING: BE AWARE OF UNEXPECTED EQUIPMENT OPERATION. KEEP HANDS

CLEAR OF ROTATING, MOVING, OR ENERGIZED COMPONENTS.

WARNING: CONSULT THE MATERIAL SAFETY DATA SHEETS (MSDSs) BEFOREWORKING WITH LUBRICANTS, CLEANING AGENTS, OR ANY OTHERMATERIAL THAT COULD BE HARMFUL, AND STRICTLY ADHERE TOTHE GUIDELINES THEREIN.

WARNING: TO PREVENT SERIOUS INJURY, ALL PERSONNEL DIRECTLY OR INDI-RECTLY INVOLVED WITH THE INSPECTION, MAINTENANCE,

REPAIR, AND OVERHAUL OF EQUIPMENT IN THE MAINTENANCEFACILITY MUST OBSERVE THE FOLLOWING PRECAUTIONS:

(1) Observe all rules and regulations provided by the Operating Authority. If there isa conflict between the instructions in this manual and the Operating Authorityrules and regulations, the latter shall govern.

(2) Disconnect power when handling equipment electrical connections or whenchecking electrical continuity. Always ground a circuit before touching its com-ponents.

(3) Take proper precautions when handling static sensitive equipment by usingstatic mats, wrist straps, and using proper grounding techniques.

(4) Maintain a clean work environment free of grease, oil, and debris. Keep thework area neat and tidy and ensure work areas are free of trip and fire hazards.

453-SWD-RMM-0103020 xi Rev. 01MO-15.98.XX.XX/6XX-020 Rev. 01

(5) Ensure area is well ventilated when working with materials that produce dan-gerous fumes. Wear protective gear when handling materials that are injuriousto the skin or eyes.

(6) When handling heavy components, select a lifting apparatus of adequate typeand capacity for the weight and size involved.

(7) Wear protective clothing and safety glasses when cleaning with compressedair to protect against flying debris. Do not direct compressed air toward anyone,as air can be forced through the skin causing death.

(8) When attaching hardware is replaced, care must be taken to ensure thatreplacement parts match the originals. Incorrectly attaching hardware canresult in personal injury or equipment damage.

(9) All personnel in the vicinity of the train must be warned to the danger of unex-pected equipment operation or train movement. Such warnings must be issuedin the form of prominently displayed temporary signs and placards as well asverbal instructions. Warning signs must only be removed by the employee whoinstalled them.

(10) Occupational health and safety regulations must be complied with when work-ing with ladders. Use strapping when ladders exceed the legislative height min-imum.

(11) Some equipment may have sharp edges and/or corners. Use caution when han-dling equipment and components, when opening access covers and equipmentlockers, and when working near any equipment enclosures, fan blades, cooling/heating fins and other such assemblies.

(12) Some equipment can be very hot or very cold while in operation. To avoid seri-ous burns, allow sufficient time for the equipment to reach a safe temperatureand measure the temperature of the equipment before performing any mainte-nance tasks.

(13) Follow all WARNINGS, CAUTIONS, and NOTES found throughout these manu-als. If you must use a work procedure or tool not covered in this manual, firstsatisfy yourself that the safety of all workers and equipment is not jeopardizedby the method selected.

SECTION 2 - DESCRIPTION AND OPERATION

2.1 SYSTEM OVERVIEW (Ref. Figs. 2-1 and 2-2)

The Centralized Control System (SCC) provides data from and control of the trac-tion power substation equipment, guideway equipment, trains, and passenger stationequipment from a central control location. The Communication Network is Ethernet

based, and supports a variety of communication layers (for example TransmissionControl Protocol / Internet Protocol (TCP/IP), User Datagram Protocol (UDP), andRemote Desktop Protocol (RDP)) and protocols such as Object Linking and Embed-ding (OLE) for Process Control (OPC), Simple Network Management Protocol

(SNMP), and Modbus as required by the various SCC equipment software modules.

The SCC subsystem is the operator's interface for remotely monitoring and control-ling (where applicable) equipment not related to control of the trains. It consists of equipment throughout the system such as workstations, servers, and ProgrammableLogic Controllers (PLCs). The SCC communicates with and gathers informationfrom most equipment in the overall system. The collected information is transferred

back to the Control Centre and the Control Centre Operator is alerted if required.The processing of SCC control requests by the corresponding subsystem is notdetailed in this manual, but can be found in the specific subsystem manual.

Figure 2-1 and Figure 2-2 illustrate the general configuration of the system.

SCC system consists of:

A. one or more field data interface devices, usually PLCs, that interface with fieldsensing devices and other hardware units.

B. a communications system used to transfer data between field data interfacedevices and control units and the computers in the SCC central host. Systemcommunication is based on radio, cable, and satellite.

C. a central host computer server or servers (sometimes referred to as the SCCCentre, master station, or Master Terminal Unit (MTU)).

D. a Human Machine Interface (HMI) software system used to provide the SCC

central host and operator terminal application, support the communicationssystem, and monitor and control remotely located field data interface devices.

The SCC provides centralized computer monitoring and/or control of the followingsubsystems:

Auxiliary Equipment Control System (SEA)

Energy Control System (SCE)

Passenger Flow Control System (SFP)

Vehicle On-board Radio System (VORS)

2.1.1 Architecture (Ref. Fig. 2-3)

The SCC network server uses WebHMI architecture to communicate with the oper-ator workstations without specialized software. This is possible because the SCCWorkstation is a Windows-based computer, and accessing the SCC server is doneusing an HTML (Web page) communication protocol. This permits easy replace-

ment of all workstations, and the ability to work from any network connected loca-tion. The SCC SQL database system is managed by the ICONICS Genesis 64software.

The Memory Based OPC [Object Linking and Embedding (OLE) Process Control]server is located on a two-slice server, the Dell Bade Server (M1000E) in the Con-trol Centre EER. OPC is a standard for connecting and communicating with indus-trial automation devices and is based on the specification from the OPC Foundation(OPC.org).

The SCC Server has redundancy that is transparent to the devices interacting with it.The subsystem interfaces to and from the SCC Server do not need special redun-dancy consideration because the server redundancy is transparent to the network

devices and processes. This redundancy includes the creation of a virtual IP addressthat allows the SCC Server to be addressed using the same IP address regardlesswhich server slice is primary. Each of the two server slices are identically config-ured to provide real-time and hot-swapable redundancy of the configuration anddatabase services. Regardless of connection method, all SCC data from all sourcesis managed in the Memory-Based OPC Server. All data collection to and from theMemory Based OPC Server is done through clients that either read or write data toit.

The OPC server is responsible for:

A. managing the SCC configuration,

B. storing historical data,


36/258


Figure 2-3. SCC Server Redundancy


37/258


C. storing trend-logger data,

D. storing alarm-logger data, and

E. scheduling of the special purpose software and interfaces to all subsystems.

Some external communication protocols or third party reporting modules exchange

data between the Memory Base OPC Server and the end devices using proprietarysoftware tools called Software-Development-Kits (SDK), through Modbus, or usingSNMP compatible protocols. Subsystems such as the CCTV and PA require soft-ware interfaces that cannot be easily embedded into the Genesis 64 product suite.The server uses external, vendor provided SDK interface applications for dataexchange between the SCC and the subsystems. All SCC workstation requests for subsystem data are made to the SCC server. The SCC server then forwards theserequests to the appropriate subsystem servers by transmitting the value of predeter-mined OPC database tags. In other words, the SCC server monitors these tags for any change, then connects to the subsystem process interface server to pass-on or collect the workstation’s request. Each database tag stores one piece of informationthat is monitored and/or controlled using the SCC Graphical User Interface (GUI)

displays. These graphic displays alert the Central Control Operator (CCO) to thesubsystem or location where an alarm or incident has occurred. Control points areselectable on the GUI display with either a keyboard or mouse. Once a point has

been selected, the command to change state is entered using the keyboard or mouseand transmitted to a subsystem interface to initiate the control action. For some sub-systems, the SCC System is integrated with them through Programmable LogicControllers (PLCs) to initiate and control actions.

2.1.2 System Network

The System Network provides communication pathways for all of the subsystems of the System. The different communication subsystems that use the network are based

on Ethernet and TCP/IP technology standards and interface with the network nodesand switches using the standard protocols.

The network provides SCC access to some of the systems aboard the trains to com-municate with monitored and controlled equipment and communication equipmentsuch as Public Address and Passenger Information.

To allow these different SCC subsystems to communicate with other subsystems inan efficient manner, they have been divided into smaller sub-groups or domainsusing Vehicle Local Area Networks (VLANs). All of the communication devices inthe system and interface with the network are grouped into one of the VLANs.

2.1.3 SCC Safety

2.1.3.1 Non-Vital Consideration

The SCC subsystem is considered a non-vital system. Even though the designensures with high probability the execution of commands or the reporting of statusand alarms, the system relies on transmission of this data which cannot be guaran-teed. The possible failure within the transmission of this information makes the SCCsystem non-vital. As such, any alarms and alarm conditions that have a safetyimpact are monitored in a secondary, vital manner through the device or system.

2.1.3.2 Operation Prevention and Protection

When devices need to be prevented from operating, such as the power supply and

distribution equipment for maintenance, the prevention and protection is not donethrough the SCC Subsystem. Prevention and Protection is provided by physical


38/258


means directly on the device using lock-out and tag-out or rack-out / tag-out proce-dures. This removes all potential for safety compromises within the SCC Subsys-tem.

2.1.3.3 Redundant Architecture (Ref. Fig. 2-3)

Redundant architecture is utilized to minimize the chance of SCC subsystem failure.The SCC Subsystem Server is a dual slice server, employing lock-step technology toensure continuous, uninterrupted operation.

The Data Transmission System (STD) is the backbone of the SCC Subsystem com-munication. It uses a redundant loop network to overcome single point failures tomaintain service.

The communication between devices uses TCP/IP protocol does not guaranteetransmission, but employs error detection and repeating features to increase the

probability of correct transmission.

2.1.3.4 Command Confirmation

The GUI control pop-ups contain a secondary confirmation step when commandinputs are initiated by the CCO. The operator must first select the desired controlaction, then confirm the selection by pressing a confirmation button. This procedurereduced the risk of any accidental commands being executed by the operator.

NOTES: 1. This feature does not apply to commands issued through the Scheduler andthus the operator should take care when scheduling any command opera-tions.

2. It is not practical to implement commands having the Command Confirma-tion feature for Scheduled commands. This is due to the potential large vol-ume of confirmation pop-ups presented to the CCO as the Scheduler

automatically manages devices. For example, a schedule for the Air Condi-tioning system using an ambient temperature sensor. The Air Conditionerstarts and stops several times each day, and the operator would need to con-firm each of these actions.

2.1.3.5 User Privileges

WARNING: THE SCC SYSTEM CAN BE OPERATED USING A SIMPLE OPC CLIENTSUCH AS THE COMMAND LINE OPC SUPPORT APPLICATION WITH-OUT USER PRIVILEGES ASSOCIATED WITH THE SCC GUI. THIS FEA-TURE, HOWEVER, PERMITS THE SCHEDULER TO INTERACT WITHTHE SYSTEM.

The SCC Subsystem controls access to certain SCC functions with user privileges.The privileges are assigned directly to users or assigned to user groups. The privi-leges that a user has determines the GUI functionality the user is permitted to access.A level of safety is achieved by not allowing users to access equipment for whichthey have not been trained. For example, a user that was only trained on passenger information calls can be prevented from operating the Power Supply and Distribu-tion system equipment.

NOTE: Access to the Scheduler for editing commands using the GUI is protected by theprivileges but do not prevent commands that are initiated through the Scheduler.


39/258


2.1.3.6 Network Security

The Data Transmission System (STD) is a contained network that normally has noaccess to the outside world. A temporary connection can be established to performupdates, however.

The Wi-Fi system (Voice and Data Mobile Communications System (SCMVD)),which extends the STD, uses WPA2 or better encryption to limit access to the STDusing mobile devices.

2.1.3.7 Input Verification

Incorrect Operator Input (intentionally or unintentionally) is the largest source of input errors. Inputs from the operator therefore have the greatest degree of verifica-tion / error-checking. Functions that pass input to other interfaces, such as the PA-

play-requests to the PA Interface, require less verification due to previous stage proofing.

Whenever an input error occurs, the system continues using default values or the

request is dropped and an error is generated. If this is not possible, the state returnsto a state that supports re-processing. For example, if a PA request is made for con-tent that does not exist, the PA Interface returns a warning through an OPC tag,drops the request, and returns to its normal state to wait for the next request.

2.1.4 Programmable Logic Controllers (PLCs)

All subsystems that are connected directly to the network and are running a TCP/IPstack require an IP address. The connections between all other subsystems con-nected to the SCC server are locally hard-wired through network-connected Pro-grammable Logic Controllers.

Programmable Logic Controllers are located in the passenger stations, the traction

power substations, and in the Depot EER. They provide real-time control and mon-itoring of remotely-located points through a modular, expandable architecture. TheModicon M340 automated platform processor manages the entire PLC station, com-

prised of discrete I/O modules, analogue I/O modules, and a communication mod-ule. These are distributed across one or more racks connected on a local bus. Eachrack must include a power supply module. The main rack supports the CPU.

2.1.5 Performance

The performance of the SCC is measured by its response time. There is no specificway to measure response time in the SCC system. The time between initiating thecommand and the corresponding status change should not be included in the per-

formance metrics because the device can take an extended period of time to changestate and the status for the state change may change at the end of the state change.For example, a track switch can take some time to move. If the status for the switchchanges after the move is complete, the performance metrics would incorrectly indi-cate that the operation took a long time.

The performance metrics used to evaluate the SCC should be:

A. One-Way Trip Time for a Modbus PLC Status / Alarm

A status or alarm generated on a device hardwired to a PLC and the time before it isdisplayed in the SCC Alarm Banner is recorded.


40/258


B. One-Way Trip Time for a Modbus Device Status / Alarm

A status or alarm generated on a Modbus device and the time before it is displayedin the SCC Alarm Banner is recorded.

C. One-Way Trip Time for an SNMP Device Status / Alarm

A status or alarm generated on an SNMP device and the time before it is displayedin the SCC Alarm Banner is recorded.

D. One-Way Trip Time for an OPC Device Status / Alarm

A status or alarm generated on an OPC device and the time before it is displayed inthe SCC Alarm Banner is recorded.

E. Command Time for a Modbus PLC Status / Alarm

A command requested to operate a device hardwired to a PLC and the time for thedevice to start the request is recorded.

F. Command Time for a Modbus Device Status / AlarmA command requested to operate a Modbus device and the time for the device tostart the request is recorded.

G. Command Time for an OPC Device Status / Alarm

A command requested to operate an OPC device and the time for the device to startthe request is recorded.

H. Other Performance Metrics

Other performance metrics include the time from the initiation of a communicationsinterface (such as PA) to the activation of the subsystem. However, such metrics are

not as critical as the above metrics because a slight delay in initiating PA is not ascritical as obtaining data in a timely manner.

2.1.6 Reliability

The reliability features of the design and architecture of the SCC system is discussedin the following paragraphs.

2.1.6.1 Redundant Server Architecture

A redundant architecture is used to minimize the chance of a SCC failure affectingoperation of the system. The SCC Server is a dual slice server employing VM tech-nology that ensures that operation continues if either slice of the server fails.

Multiple servers with the same virtual state image of the server are continuouslyupdated. If the primary server fails, the virtual state image is continued by another virtual server.

The SCC Server has a network card that allows the network card in each server sliceto be grouped together into one virtual network card. This allows either server sliceto communicate on the virtual network card. The SCC Server redundancy is com-

pletely transparent to these devices and adds to the reliability because they do notneed additional complex code to support the redundancy functionality.


41/258


2.1.6.2 Redundant Network Architecture

The Data Transmission System (STD) is the backbone of the SCC communicationnetwork. The Data Transmission System is a redundant loop network with the abil-ity to overcome single points of failure while maintaining service.

2.1.6.3 Redundant Protocol ArchitectureMost of the communication between devices uses TCP/IP technology. TCP/IP doesnot guarantee transmission, but has an error detection and retransmission features toincrease the probability of correct transmission.

2.1.6.4 Minimal Workstation Installation

The workstation uses the WebHMI technology to minimize the amount of softwarethat needs to be installed on the workstation. Minimal software is installed on theworkstation to allow a workstation to be replaced quickly. The GUI does not haveany hardware specific requirements besides the minimum requirements.

2.1.7 Maintainability

The SCC Server modules are designed to use common interfaces such as OPC,SQL, and TCP/IP to allow the modules to interact without being specificallydependent on each other.

In most cases, a module can be swapped out and replaced by a similar module aslong as that module uses the same interface. For example, the Poller module can bereplaced with an off-the-shelf Modbus poller module provided by others. Since bothof these modules perform Modbus to OPC conversion they can be swapped withoutsignificant modification. Modules use configuration files to determine many of the

parameters of the module allowing them to be re-configured easily.

SCC Modules are monitored by a Watchdog process that tracks the importantactions of the modules. This Watchdog is purely a monitoring aid, but allows theuser to get a quick summary to see the latest actions of the various modules. Thishelps identify and isolate faulty modules.

2.2 ARCHITECTURE OVERVIEW

The SCC software architecture is based on the Windows 7 Microsoft 64-bit Operat-ing System (OS). Other software such as the Iconics Genesis 64, SQL Database,vendor proprietary SDKs, and communication modules are layered onto the server.

NOTE: This document does explain the processing of any SCC requests carried out byother subsystem servers. For example, this document includes the architecture

and design of the SCC interface to PA but it does not include architecture anddesign of how the PA server carries out the SCC request.

2.3 SCC SUBSYSTEM CORE COMPONENTS ARCHITECTURE (Ref. Fig. 2-4)

At the core of the SCC is a Memory Based OPC Server for runtime, SQL database,and historical data. All real-time data, monitoring, or control eventually begins or ends in the Memory Based OPC Server. This runtime OPC Server is referred to as aMemory Base because it does not initiate any data collection. All data collection toand from the Memory Based OPC Server is done through OPC clients connecting tothe Memory Based OPC Server for reading or writing data.

Data in the Memory Based OPC Server is logged through different processes.

Depending on the data type, it is logged to the SQL historical database and retrievedas a trend, unlike the Memory Based OPC Server for current (latest) data value.


42/258


453-SCC-02-012

Figure 2-4. SCC Server Software Architecture


43/258


2.4 SCC CORE SUPPORT COMPONENTS ARCHITECTURE (Ref. Fig. 2-4)

The Unified Data Manager (Alarm Process), Alarm Server, Alarm Logger, andTrend Logger are all support components of the SCC Subsystem Core.

2.4.1 Unified Data Manager

The Unified Data Manager (Alarm Process) does most of the data processing todetermine if signals are in alarm state or not. Most of the equipment data in theMemory Based OPC Server is packed in 16 bit registers. The Unified Data Manager (Alarm Process) extracts the individual signals where applicable. This is done toevaluate the signals against predefined criteria to determine if the signal is in alarmstate or not. The results of this computation are passed on to the actual Alarm Server.By utilizing the Unified Data Manager (Alarm Process), most of the alarm process-ing is delegated from the Alarm Server to provide higher performance.

2.4.2 Alarm Server

The Alarm Server adds standard Alarm Server functionality to the signals extracted

from the Memory Based OPC Server. This enables features such as storing the alarmstate, the acknowledged state, and summary functions such as the number of activeor unacknowledged alarms in a group of related signals. The Alarm Server displaysthis information in the real-time Alarm Banner in the SCC GUI.

2.4.3 Alarm Logger and Trend Logger

The Alarm Logger and Trend Logger store data from the Alarm Server or the Mem-ory Based OPC Server in the historical SQL database. The Trend Logger, on theother hand, stores analogue data based on an interval or when it changes from thelast logged value by more than the dead band value.

2.5 SCC DATA COLLECTION ARCHITECTURE (Ref. Fig. 2-4)

The SCC supports four methods of data exchange: OPC, SNMP, Modbus, and TextFile Exchange. The first three methods (OPC, SNMP and Modbus) are illustrated inthe bottom left corner of Figure 2-4.

2.5.1 Modbus Over TCP/IP and Poller Control Devices

There are three different sources of Modbus over TCP/IP protocols and the SCC uti-lizes two different processes (Poller and Conditional Poller) to read these source

protocols.

2.5.1.1 Source 1

PLCs are hardwired to devices and communicate with the SCC using Modbus over TCP/IP. The PLCs are Polled by the SCC Modbus Poller; the SCC communicateswith the Poller module and not the actual PLCs. The SCC Poller module is astraightforward Modbus polling application with support for dual IP address devices(for example, redundant devices). The Poller module performs any scaling or offsetneeded to convert the raw analogue data into final values. The Poller module uses astatic configuration file to determine which registers are read and converts the PLCdata to its corresponding OPC tags on the Memory Based OPC Server.

2.5.1.2 Source 2

The SCC Poller communicates directly with the Modbus over TCP/IP devices actualend device and not through an intermediate PLC.


44/258


2.5.1.3 Source 3

The third type of devices support the Conditional Modbus Poller module, such asused in the train TMS touchscreens. The Conditional Poller module is the same asmentioned above but it also reads a set of Change Bit Registers indicating whichgroups of data have changed since the last poll. This permits polling of a much

smaller set of data for only the blocks of data that have changed.

Similarly to the Poller module, the Conditional Poller module performs any scalingor offset needed to convert the raw analogue data into final values. The ConditionalPoller module uses a dynamic configuration file controlled by the change bit regis-ters to indicate which blocks of data to read.

2.5.2 SNMP Data

The baseline OPC uses an SNMP GET command (as opposed to SNMP TRAP com-mand) to obtain SNMP data. Since the SNMP Manager does not provide functional-ity for scaling raw data, the results of the SNMP Manger are passed through theUnified Data Manager (Raw Data Bridge) to the memory-based OPC Server.

2.5.3 OPC Data

The GenBroker module is used to facilitate OPC communication between servers ondifferent machines. This module takes care of the DCOM and other handshaking toallow the two different servers to communicate using OPC. Since GenBroker onlyenables communication, the data is passed through the Unified Data Manager (RawData Bridge) in order to provide scaling and
