MANUAL SPECIAL NOTATIONSIn the ALSTOM manuals, there are three methods used to convey special informationalnotations to the reader. These notations are warnings, cautions, and notes. Bothwarnings and cautions are readily noticeable by boldface type two lines beneath thecaption.WarningA warning is the most important notation to heed. A warning is used to tell the readerthat special attention needs to be paid to the message because if the instructions oradvice is not followed when working on the equipment then the result could be eitherserious harm or death. The sudden, unexpected operation of a switch machine, forexample, or the technician contacting the third rail could lead to personal injury or death.An example of a typical warning notice follows:CautionWARNINGDISCONNECT THE MOTOR ENERGY WHENEVER THE GEAR COVERIS REMOVED. OTHERWISE, THE SWITCH MACHINE MAY OPERATEUNEXPECTEDLY AND POSSIBLY CAUSE PERSONAL INJURYA caution statement is used when an operating or maintenance procedure, practice,condition, or statement, which if not strictly adhered to, could result in damage to ordestruction of equipment. A caution statement is also used when personnel could besurprised if shocked by a circuit operating at a low current. A typical caution found in amanual is as follows:NoteCAUTIONTurn power off before attempting to remove or insert circuit boards into amodule. Boards can be damaged if power is not turned off.A note is normally used to provide minor additional information to the reader to explainthe reason for a given step in a test procedure or to just provide a background detail. Anexample of the use of a note follows:NOTEA capacitor may be mounted on the circuit board with a RTV adhesive.Use the same color RTV.P2511G, Rev. Jan/06ALSTOM Signaling Inc.

VPI II Organization2. SECTION 2 – VPI II ORGANIZATION2.1. GENERALThis section describes the organization of the VPI II system.2.2. VPI II SUBSYSTEMSThe VPI II system can be subdivided into five main subsections as shown below:VPI IIChassisVital SubsystemNon-VitalSubsystemApplication ToolsCommunicationsProtocolsFigure 2-1. VPI II Breakdown2.3. GENERAL CHARACTERISTICSThe VPI II module is a Vital fail-safe, microprocessor-based control system designed tomeet the needs of interlocking control for mainline railroads and mass transitapplications. Designed as a modular control system, it contains a set of plug-in PrintedCircuit Boards that are applied in varying quantities to meet the needs of a specificproject. Although one VPI II system is sufficient for many installations, additionalsystems in distributed arrangements can be added for sites that are more complex(and/or have specific availability requirements). A single VPI II system may include 1 to4 chassis depending on I/O and arrangement. Single VPI II systems controllinginterlockings with 35 point machines have been proposed. However, the largest singleVPI II system installed so far has 20 points machines, and the average number of pointmachines per system tends to be less due to specific project availability requirements.The VPI II system can be mounted in a small, wayside equipment shelter. No specialheating or cooling equipment is required for operation in AREMA-specifiedenvironments of Class C or Class D (-40 to +70 degrees C). Built-in secondary transientprotection is provided for all I/O lines to prevent disruption of service from EMI or otherlocal interference. If required, additional primary protection devices can be added to theexternal lines to protect against higher level EMI such as pulses from nearby electricalstorms. Typically, no interface devices are required between the VPI II inputs andoutputs and the standard interlocking appliances.P2511G, Rev. Jan/06 2–1 ALSTOM Signaling Inc.

VPI II OrganizationThe interlocking relay logic is reduced to either a closed set of Boolean mathematicalexpressions or expressed graphically using Relay/Ladder Logic diagrams whichrepresent standard relay contact closures energizing coils. Then, using an ALSTOMComputer-Aided Application Programming Environment (CAAPE) software package,these Boolean expressions are converted into operating instructions for the VPI IImicroprocessor. Both Vital and non-vital applications are created with the same userinterface. The CAAPE software package is also used to configure the hardware of theVPI II chassis.The tool set includes a graphical simulator that allows the signal engineer to exercisethe logic before building the hardware. The simulator provides a mechanism for thesignal engineer to demonstrate the operation of the interlocking before the design iscomplete. As such, it can offer clarifying detail to design reviews. The simulator can alsobe used in presenting the application design to non-signaling personnel, e.g., operatingpersonnel, to insure that the signal design adequately supports the operational needs.The VPI II system has separate subsystems for Vital and non-vital control. The Vitaland non-vital logic and hardware are maintained as separate subsystems to allowmodifications in one section to not affect the other. These subsystems may share achassis or may be configured in separate chassis. Refer to Figure 2–2 for a generalblock diagram of a portion of a control system with two VPI II systems.2.4.

Chassis Configurations3. SECTION –3 CHASSIS CONFIGURATIONS3.1. GENERALThis section describes the chassis configurations of the VPI II system, and is organizedas shown in Figure 3–1.ChassisPlug Coupled Direct WirePCB Interface CoversFigure 3-1. VPI II ChassisP2511G, Rev. Jan/06 3–1 ALSTOM Signaling Inc

Chassis Configurations3.2. PLUG COUPLED CHASSISThe VPI II plug coupled chassis includes internal cable harness assemblies. Theseassemblies connect the VPI II PCB I/O point(s) to a series of AMP type M-series plugcouplers, mounted on the rear panel of the chassis. The rear panel also contains a 14-pin type M-series plug coupler for the 5 VDC power connection and provisions for up tofour 60-way ribbon cable connectors for connecting to expansion chassis.Figure 3-2. Plug Coupled ChassisPlug CoupledChassisCaseCableHarnessFigure 3-3. Plug Coupled Chassis ComponentsP2511G, Rev. Jan/06 3–2 ALSTOM Signaling Inc

Chassis Configurations3.2.1. CaseThe VPI II plug coupled chassis can be provided in two basic case configurations. Oneto four chassis can be used to complete a single system. The chassis may be a mixtureof the two types. The two basic types are the split motherboard and the continuousmotherboard that busses the center connector (P2) of the printed circuit boardstogether. Each chassis contains 21 printed circuit board slots.The split motherboard version of the chassis is configured to connect the P2 connectortraces from chassis slots one through five together and slots six through twenty-onetogether. Since the VPI II system uses the P2 connector as the I/O bus, this allows Vitaland non-vital I/O to be housed in the same chassis. For example, the first five chassisslots could be used to house non-vital I/O and the non-vital processor. Slots from 6 to21 could contain Vital I/O along with the Vital I/O controller (I/O bus).NOTEOther system boards may also be required to configure a proper operatingsystem and several other arrangements could be possible.The continuous motherboard version of the plug-coupled module connects all the slots(1 –21) of the P2 connector together. This requires that all the I/O housed in the modulebe either Vital or non-vital. In addition, a CSEX board can be housed in this module withVital I/O as long as no non-vital I/O is also housed in the module.An extra deep, plug coupled chassis is offered to provide more space for internal cablessuch as the 38216-497-XX cable assemblies. For those systems with large numbers ofI/O’s this makes access to the back of the motherboard and 5 VDC power filter easier.Table 3–1.

Chassis Configurations3.2.2. Cable HarnessThe chassis require specific cable harness assemblies to be installed based on the PCBconfiguration. Ribbon cables are required for the main system bus. This is a 60-wayribbon cable, which connects the main system boards together. The number of positionsor slots required for this cable is dependant upon the number of main boards beinginstalled. The boards connected by this main bus are CSEX, VRD, CPU II, IOB andVSC. The VRD PCB takes 2 slots.Cable harnesses are also required to connect the PCB edge connectors to the plugcouplers on the rear cover of the chassis. These cables are detailed below. There are21 available plug coupler locations on the rear panel and four 60 way ribbon cablelocations. The blank plates listed below are used to cover the unused locations. Also,there are several variations of output and input cables to provide a variety ofarrangements of plug couplers and board configurations.P2511G, Rev. Jan/06 3–4 ALSTOM Signaling Inc

Chassis Configurations3.3. DIRECT WIRE CHASSISThe direct wire chassis is configured to allow the I/O wiring to be economical by directlyinserting wire into the PCB edge connectors in the chassis. This chassis configurationdoes not allow for quick removal of the chassis from a wired rack. However, all thePCBs can be removed and no active electronic components are left in the chassis. Thisversion is intended for applications where the rack housing this chassis provides a plugcoupledconnection to the other interlocking equipment.Figure 3-4. Direct Wire ChassisP2511G, Rev. Jan/06 3–5 ALSTOM Signaling Inc

Chassis Configurations3.3.1. CaseThe VPI II direct wired chassis can be constructed from two basic case configurations.One to four chassis can be used to complete a system. The chassis may be a mixtureof the two types. The two basic types are the split motherboard and the continuousmotherboard that busses the center connector (P2) of the printed circuit boardstogether. All chassis contain 21 printed circuit board slots.The split motherboard version of the chassis is configured to connect the P2 connectortraces from chassis slots one through five together and slots six through 21 together.Since the VPI II system uses the P2 connector as the I/O bus, this allows Vital and nonvitalI/O to be housed in the same chassis.

Slots from 6 to 21 couldcontain Vital I/O along with the Vital I/O controller (I/O bus).NOTEOther system boards may also be required to configure a proper operatingsystem and several other arrangements could be possible.This chassis can also be supplied with an optional rear panel. This panel is used toprovide connection points for diagnostic equipment connections; chassis to chassisribbon cable connections and power supply connections.P2511G, Rev.

The boardsconnected by this main bus are CSEX, VRD, CPU II, IOB and VSC. The VRD boardtakes 2 slots.P2511G, Rev. Jan/06 3–7 ALSTOM Signaling Inc

Chassis Configurations3.4. PCB INTERFACE CHASSIS (CPIB)The PCB interface chassis uses printed circuit cards with WAGO style (spring clip) wiretermination blocks and PCB edge connectors to map the I/O termination points on theVPI II PCBs to discrete wire connectors. The chassis is designed to allow theseinterface PCBs to be inserted and removed from the rear of the chassis. This provides awire termination method that can be quickly disconnected (by removing the PCBs) andindividual I/O points may be disconnected for troubleshooting. This chassis style isintended for low density applications. See Figure 3–5 for a photo of a PCB InterfaceChassis.Figure 3-5. PCB Interface ChassisPCB InterfaceChassisCaseInterface BoardsFigure 3-6. PCB Interface Chassis ComponentsP2511G, Rev. Jan/06 3–8 ALSTOM Signaling Inc

Chassis Configurations3.4.1. CaseThe PCB Interface case is similar in arrangement and options to the plug-coupled anddirect wired cases. The difference in this case is that an additional set of card guides isinstalled on the rear of the chassis for the interface PCBs. The case descriptions inTable 3–3 include a list of the boards in each case. The individual boards are discussedunder Section 4 (Vital Subsystem) and Section 5 (Non-Vital Subsystem).This chassis uses a fixed PCB for the main system bus and therefore a main systemcable is not used.Table 3–3.

Vital Subsystem4.2. CPU II (CENTRAL PROCESSING UNIT II) BOARD 31166-374-XXThe CPU II board is designed as a system board for VPI II incorporating Vital logicprocessing, Vital I/O control and monitoring, on-board programming, and extendedcapacity for larger interlockings. The board is designed using primarily SMT (SurfaceMount Technology) parts.The CPU II contains two 80386EX33 microprocessors that separately perform the Vitalprocessing and high-speed communications functions.The CPU II board controls the System bus over which the CPU II, VRD, CSEX, VSCand IOB boards communicate.Figure 4-2.

Vital Subsystem4.3. VRD (VITAL RELAY DRIVER) BOARD 59473-740-XXThis board plays a key role in assuring the vitality of the system. It produces an outputvoltage that operates a 100-ohm ALSTOM Type B1 relay (P/N 56001-787-05) if, andonly if, the data sent to it by the main processing system is exactly correct. If any ofthese checkwords are not precisely correct, the VRD output is shut off and the externalrelay de-energizes. The field energy that is delivered to the Vital output boards is brokenthrough front contacts of this Vital relay or a repeater of it. Thus, power will be removedfrom the outputs when the Vital checkwords are incorrect.4.3.1. Physical CharacteristicsThe processing portion of the VRD board is based on an 8085 microprocessor chip with4K of EPROM program memory and 4K of RAM. The RAM is shared with the mainprocessing system and is the means by which the checkwords are transferred.Figure 4-3. VRD BoardP2511G, Rev. Jan/06 4–4 ALSTOM Signaling Inc.

Vital Subsystem4.4. VSC (VITAL SERIAL CONTROLLER) BOARD 59473-939-XXThe Vital Serial Controller board is a microprocessor-based board that provides ameans for exchanging the states of Vital interlocking functions between interlockingsystems in a Vital manner. This board family was first designed to provide Vital VPI II toVPI II Vital communications more efficiently than line wires. There are two types of datatransmission interfaces; one for private copper pairs and one for generic, EIA232, DCEconnection. A daughter board is used to provide the EIA232 connection, so the numberof chassis slots required for this interface is two (2).Two additional applications of the VSC were created to provide a means ofcommunicating to and from AF Track Circuit modules (MVSC) and programmableGenrakode modules (GVSC or GVSCE).The system software installed on the Vital Serial Controller board is associated with aparticular version of system software on the Vital processor board. Each type of board,MVSC, GVSC, GVSCE, or VSC, has its own unique Vital system software that is notinterchangeable.4.4.1. System CapacityUp to ten VSC boards or combinations of VSC, MVSC, GVSC, GVSCE, and CRGboards can be supported by a single Vital subsystem. See Table 4–5 for moreinformation on permissible combinations of these boards.Figure 4-4. VSC BoardP2511G, Rev. Jan/06 4–6 ALSTOM Signaling Inc.

Vital Subsystem4.5. CRG (CODE RATE GENERATOR) BOARD 31166-261-XXThe Code Rate Generator Board is a Vital VPI II board that receives code ratecommands from the CPU II board. The received code rate commands are decoded andused to generate 8 coded outputs. The frequency and duty-cycle of the coded outputsare vitally verified by using an absence of current detector (AOCD). During the on andoff portions of an output’s coding cycle, data is circulated through the AOCD. Datareturned from the AOCD, coupled with other Numerically Integrated Safety AssuranceLogic (NISAL) processing verifications, are used to generate a message that the CRGboard sends to the CPU II board. The message received by the CPU II board from theCRG is used as part of the generation of the VRD checkword. All outputs are generatedusing a Double Break Output (DBO) DC-DC converter and, as such, are isolated fromeach other by >2000 Vrms and protected from undetected single fault failures.Figure 4-5.

It provides a storage medium for test data obtained during Vitalinput and Vital output port checks. The board includes logic to control the continuousverification of Vital output port states. Each chassis containing Vital input or outputboards including the Field-Settable Vital Timers (FSVT) must have an IOB board.Figure 4-6. IOB BoardP2511G, Rev. Jan/06 4–11 ALSTOM Signaling Inc.

Vital Subsystem4.8. VITAL DC OUTPUT BOARDS 59473-739-XX, -747-XX, -977-XX, -749-XX,31166-340-XXThere are four types of Vital DC Output boards:• Single Break: SBO, 59473-739-XX• Double Break: DBO, 59473-747-XX• Double Break 50 V: DBO-50V, 59473-977-XX• Lamp Driver: LDO, 59473-749-XX or LDO2, 31166-340-XXAll are configured with eight Vital outputs per board. The single break output isanalogous to a single relay contact placed in the positive or feed side of the circuit. Theequivalent to the relay contact in the solid state circuit is the FET switch. The doublebreak output is analogous to a relay circuit with the contacts in both the feed and returnsides of the circuit. With the solid-state equivalent, however, each output is completelyisolated from all other outputs and/or power supplies. The lamp driver's output isequivalent to a single relay contact in the return or common side of the circuit.All outputs use a circuit (AOCD) that detects current to vitally determine the state of thecircuit. If the current is greater than the threshold value, the output is considered in the"ON" state. It is only proven to be "OFF" if the current is less than the AOCD threshold.Figure 4-8.

GENERALThis section describes the Non-Vital subsystem of the VPI II system, and is organizedas shown in Figure 5–1.Non-VitalSubsystemCSEX Non-Vital Inputs Non-Vital OutputsTrain to WaysideCommunicationsFigure 5-1. Non-Vital Subsystem5.2. NON-VITAL PROCESSOR FAMILY (NVP)The non-vital processors perform important communications, data logging and non-vitallogic operations within the VPI II system. There have been three generations ofprocessor boards with generally increasing functionality. All the non-vital processors arereferred to as CSEX which stands for Code System Emulator eXtended. The first CSEXboard family was the 59473-938 series. This board was developed to support multiple,non-vital communications links simultaneously and to permit the separation of the nonvitalapplication from the Vital to better support the non-vital application requirements.The CSEX2 board family, 31166-049 series, enhanced the flexibility of configuration ofthe non-vital communications interfaces and the first generation of data logging. Thelatest family, CSEX3, 31166-175 series, was designed to support larger, moredemanding non-vital applications and provided a greater depth of memory for datalogging. The CSEX3 was also designed to be a plug-in replacement for either the earlierCSEX or CSEX2 board assemblies.P2511G, Rev. Jan/06 5–1 ALSTOM Signaling Inc.

CSEX3 (Extended Code System Emulator 3) Board 31166-175-XXThe CSEX3 (Code System Emulator eXtended) board is an upgrade for both the CSEX(59473-938-XX) and CSEX2 (31166-049-XX) boards. It is designed as a system boardfor VPI II as well as a stand-alone non-vital logic processor. The CSEX3 board has sixserial ports for communications to external devices, such as modems, other CSEXboards, etc. A DC code line interface is available as well as EIA232, EIA422, andEIA485 interfaces. The CSEX3 board provides an interface to non-vital inputs andoutputs for local control of interlockings. Battery-backed RAM is also available for datalogging. The CSEX3 board is designed using primarily SMT (Surface MountTechnology) parts. CSEX3 supports up to 20 non-vital I/O boards.Figure 5-2. CSEX3 BoardP2511G, Rev. Jan/06 5–2 ALSTOM Signaling Inc.

Non-Vital Subsystem5.5. TRAIN TO WAYSIDE COMMUNICATIONS BOARDSThe Non-Vital Train-to-Wayside Communications Modem board is the wayside part ofthe Train to Wayside Communications (TWC) system. TWC is a two-waycommunication link consisting of a transmitter/receiver set (transceiver) aboard the trainand a similar set in wayside systems. The system provides communication between thecar-carried equipment and the wayside equipment for the transfer of routing, dispatchinformation and for monitoring by central control. This board demodulates analogfrequency information into a digital form and passes it on to the NVP board (CSEX2 orCSEX3 board). It also takes digital information from the NVP board and converts it toanalog frequency form to be transmitted to the train.As with the CSEX board series, the TWC board series has evolved over the years ofapplication to reach higher levels of integration and functionality. The present boardassemblies supporting the TWC function are the 31166-119 series.5.5.1. NVTWC-FSK (Non-Vital TWC FSK) Board 31166-119-XXThe Non-Vital TWC FSK board provides true Frequency Shift Keying TWC. Theincoming TWC messages are keyed such that the logic 1 and logic 0 frequencies arebased symmetrically around some base frequency (example: 9650 ± 150 Hz). Thisboard uses 4 Phase Lock Loops (1 per channel) to decode the incoming signals. Theoutput of the phase lock loops are then reformatted so that they can then be sent to theCSEX board. Firmware on board validates the received message before it is sent to theNVP to reduce or eliminate the effects of noise-induced errors.Figure 5-8. NVTWC-FSK BoardP2511G, Rev.

Design, Test and Validation Tools6.5. TRACKER REMOTE DIAGNOSTIC ANALYZERTracker is a software package with a number of features intended to make problemdetection and diagnosis easier for the user. A PC based Windows product, Tracker isused to automatically identify VPI system failures and produce alarms at a central site.Tracker also serves as a centralized server for the collection of VPI Datalogger eventrecords from field sites. Basic features are fault detection, logging, data retrieval andreport creation.6.5.1. Fault DetectionIn the convenience of an office setting, the Tracker Diagnostic Analyzer Software canprovide full-time and part-time monitoring of multiple field device sites simultaneously,and can be configured to sound an alarm when a malfunction occurs. When a fault isdetected, the Tracker software can be configured to diagnose the problem to indicatethe fault or field condition. This helps ensure that proper spares are taken to the site thefirst time, thus minimizing system down time.6.5.2. LoggingThe Tracker software provides an historical log of errors detected so that the eventsleading up to a particular failure can be later analyzed for possible trends. Based onanalysis of the log, preventive action may be possible to protect against futureproblems.6.5.3. Data Retrieval And Report CreationTracker can retrieve historical event data from field devices for archival and analysis.Reports are available.P2511G, Rev. Jan/06 6–10 ALSTOM Signaling Inc.

Design, Test and Validation Tools6.6. TESTWRITETestWrite is a software package generally used by a quality assurance engineer orcircuit check design personnel to separately validate that the logic being implementedby the interlocking logic design engineer meets the safety critical needs of the railroad.The user easily generates a track layout from a set of graphical tools. TestWrite canthen automatically determine all routes in the system. The user then builds test steps foreach route, by assigning states (inputs/outputs) to each graphical element. Steps canbe grouped to form individual test scenarios. TestWrite then develops a test descriptiondocument for the assigned test scripts. The final document is available in Word or textformat.For interlocking configurations, the tool is used to create a set of rules that reveal howthe interlocking functions, route, time, indication, locking are to operate and be tested;independent of the actual signal design executable. Sample output for the TestWritetool are included below. The features this tool provides are indicated here:• Quick Track Layout Builder – simple graphical tool to draw track layout. Symbols fortracks, switch machines, signals, etc are available. This graphical view of theinterlocking is later used by the VPI MMS as an active display to provide actual localcontrol panel displays or used as the visual display of test results.• Route Wizard – Analyzes the final track layout and generates a listing of routesthrough the interlocking. This list along with the physical elements assigned form thefoundation for defining test strategies.• Test scenario reports – for each route, a test scenario is defined that provides asequence of test to be performed. When test scenarios are initiated through the VPIMMS, the test scenarios are provided to a graphical display for assisting the testengineer through the test.TestWrite has four intended uses:• circuit check of electronic or relay based interlocking logic• generation of test sheets for reducing factory and field test time• secondary use for training signaling employees on interlocking rules specific to theoperating authority and, in the future• a framework to be used for performing automatic interlocking tests mandated byFRA or other regulatory bodiesP2511G, Rev. Jan/06 6–11 ALSTOM Signaling Inc.

Design, Test and Validation ToolsThe benefits of using TestWrite are:• consistent rules for design• standardization of test sheet generation• electronic reports of actual factory or field test sequences executed by test engineerFigure 6-8 is an example TestWrite screen, Figure 6-9 is and example TestWrite report.Figure 6-8.
