1 Scope and Application This document describes the interface requirements between the signalling system and the Signalling Control System.

For new interlockings this document shall be used as the interface requirements to the Signalling Control System. The interlocking design is expected to follow the naming convention and the meaning of the indications and controls as defined in this document.

For existing interlockings this document is intended to be used as the requirements for the signalling interface design if it is modified for remote control.

For some installations a separate maintenance system may be provided to capture diagnostic indications for maintainers. When this is provided, a reduced set of indications may be provided to the Signalling Control System. When this occurs, the interface is to be documented as described in Section . Mandatory indications and controls for the Signalling Control System are noted in and Appendix B respectively..

Figure 1 - Interface Overview

In this document “the interface” refers to the interface between the signalling system and Signalling Control System unless otherwise specified.

The physical interface usually takes the form of a serial communications link between field located interlocking equipment, & a remotely located control system.

This document identifies the types of signalling systems and interface equipment that the Signalling Control System connects to. It also defines the logic states of the indications and controls in terms of the electrical interface or protocol.

4 Indication and Control States This section defines the states of indications and controls that shall be used by the Signalling Control System.

4.1 Indications The signalling control system is required to be able to display each state as ON, OFF or UNKNOWN.

Where failure of the signalling equipment or components of the signalling equipment or telemetry equipment cannot be determined entirely from the communications link, equipment health indications shall be provided. For example if a Microlok field slave fails then the indications received from the Microlok master will need to be marked as unknown by the control system. A Slave_OK indication is required to achieve this, see Cardfile OK in Appendix A.

Health indications shall be associated with the indications they affect.

Health indications shall be processed before changes to their affected indication bits by the Control System.

4.2 Controls The Signalling Control System states of signalling controls shall be :

Steady OFF

Steady ON

Pulse ON – The output is set to ON then OFF

Pulse OFF – The output is set to OFF then ON

The type of control & the duration of the pulse shall depend on the hardware interface. See section 5.

5 Hardware Interface This section identifies the connection details for the signalling system and relates the physical interface to the states of the Signalling Control System indications and controls.

5.1 Equipment types The Signalling Control System interfaces shall include the capability to interface to signalling systems of the following interlocking types:

Sup

a) Relay

b) Microlok

c) SSI and Westlock

d) Westrace

The Signalling Control System interfaces to Relay interlocking shall include the following types of telemetry equipment:

a) SCADA 2000

b) Dupline

c) IMAC

d) Kingfisher Telemetry Systems

The Signalling Control System interfaces to signalling ancillary systems may also include the following types of equipment:

a) Power supply equipment – rectifiers, Switch mode supplies, Uninterruptible power supplies (UPS) including bypass on line, on battery etc, Emergency Change Over contactors (ECOs), Earth Leakage Detectors (ELDs), miscellaneous indications – voltage free relay contacts.

b) Air compressor systems – Control PLCs, pressure switches, compressor alarms and miscellaneous indications – serial data, USB or voltage free contacts.

c) Fire alarms.

d) Data Link switches, routers.

e) Trackside monitoring (e.g. dragging gear detection, etc.)

5.2 Telemetry Equipment The wiring connections from any telemetry system to the signalling system shall be included in the signalling design circuits.

5.2.1 SCADA 2000 The SCADA 2000 is a telemetry system, which can be duplicated to improve availability. The connections to the interlocking are via optoisolator boards.

5.2.1.1 Indications The input circuit may be a single contact, or a logic circuit of a number of contacts.

The Signalling Control System shall detect indications as:

ON: when the input circuit is closed and the required voltage is applied to the input terminal.

OFF: when the input circuit is open.

Vital Indication Optoisolators (VIO) may be used where an intermediate point of a vital circuit is required as an input, such as for RUZR indications. A circuit including the VIO then drives an input Optoisolator as per conventional inputs.

5.2.1.2 Indication Conditioning Indication conditioning is set by the Signalling Control System; there are no hardware interface requirements for indication conditioning.

5.2.1.3 Controls Controls shall have the following effect on outputs:

Steady ON: current is allowed to flow

Steady OFF: no current is allowed to flow.

For Pulse ON controls the output is set to ON and after 1 second set to OFF. This conversion is performed by the SCADA 2000 system. Pulse OFF controls are handled similarly.

Controls are only set ON by the master side. For the Standby side all controls are set OFF. On a change of mastership there will be an overlap where both sides are master to ensure that the signalling control outputs do not drop out.

5.2.2 DUPLINE Dupline is a telemetry system, which can be duplicated to improve availability.


Indications shall be detected as:



5.2.2.2 Indication Conditioning Dupline has no indication for input module failures

A hard-wired health indication shall be supplied per input module.

This input is wired directly to the indication bus voltage. If there is a failure of the module then all indications from the module will be set OFF, including the health indication. When this is detected all other inputs from the module are made UNKNOWN.

Dupline has two failure modes “ALL ON” and “ALL OFF” with only the “ALL OFF” failure mode being alarmed.

5.2.2.3 Controls No control shall be issued using Dupline telemetry systems.

5.2.3 IMAC IMAC is a telemetry system, which can be duplicated to improve availability.

5.2.3.1 Indications IMAC input modules use a sense current to determine if the input circuit is closed. For this reason one circuit or contact cannot be used for duplicated inputs. Two contacts, or duplicated input circuits are to be used for duplicated system. The input circuit may be a single contact, or a logic circuit of a number of contacts.


ON: when the input circuit is closed.


IMAC input modules can be configured to invert the logic sense of the inputs using DIP switches. This feature is not used.

5.2.3.2 Controls No control shall be issued using IMAC telemetry systems.

5.2.4 KINGFISHER Kingfisher is a telemetry system that which can be duplicated to improve reliability.





5.2.4.2 Controls Use of controls through Kingfisher is permissible in accordance with 5.2.1 above, however, receipt on both sides may be required for the application.

5.3 Computer Based Interlockings

5.3.1 SSI The Signalling Control System shall interface to SSI interlockings via a serial communications link using the BR1631 protocol.

The connection point shall be the RS422 ports provided by the Panel Processor Modules (PPM). Each SSI cubicle has two PPMs with one RS422 port per PPM for the interface.

5.3.1.1 Indications Indications are received via the protocol. The indication values shall be:

ON: SSI value of TRUE which is indicated by a ‘1’ in the protocol message.

OFF: SSI value of FALSE which is indicated by a ‘0’ in the protocol message.

5.3.1.2 Controls Requests shall only be sent by the master Signalling Control System side. On a change of mastership there will be an overlap where both sides are master.

Control values sent via the protocol are set to:

ON: SSI value of TRUE which is indicated by a ‘1’ in the protocol message.

OFF: SSI value of FALSE which is indicated by a ‘0’ in the protocol message.

5.3.2 Westlock The Signalling Control System shall interface to Westlock interlockings via a serial communications link using the RT/E/S/17503 protocol.

The connection point shall be the RS422 ports provided by the Control System Gateways (CSG). Each Westlock system has two CSGs. Each CSG can have multiple addresses with one RS422 port per address on each CSG.

The RT/E/S/17503 protocol is identical to the SSI BR1631 protocol. See section 5.3.1 for definitions of Indications and Controls.

5.3.3 Microlok The Signalling Control System shall interface to Microlok interlockings via serial communications links using the Genisys protocol. Two Genisys links shall be provided.

5.3.3.1 Indications The values of the indications received via the protocol shall be:

ON: Microlok value of TRUE which is indicated by a ‘1’ in the protocol message.

OFF: Microlok value of FALSE which is indicated by a ‘0’ in the protocol message.

5.3.3.2 Controls Controls values sent via the protocol are set to:

ON: Microlok value of TRUE via a ‘1’ in the protocol message.

OFF: Microlok value of FALSE via a ‘0’ in the protocol message.

Where Microlok requires controls to be pulsed ON or OFF, the duration shall be configurable in the Signalling Control System. The duration will typically be set to 1 second but shall not be greater than 2 seconds.

Controls shall be sent from both the master and the standby Signalling Control System side.

5.4 Electrical Isolation Signalling interlocking equipment shall be electrically isolated from control system equipment or communication equipment. This is to avoid lowering the electrical integrity of signalling systems & avoid the transference of electrical surge between systems.

5.4.1 Relay Based Systems All wiring connected to vital circuits shall conform to railway signalling standards for vital wiring. Equipment connected to such wiring is subject to Type Approval to ensure adequate isolation is provided between the vital & non-vital elements of the system.

5.4.2 Computer Based Systems All connections between vital computer systems & communication equipment, or control equipment shall be isolated.

6 Interface properties This section describes the properties of indications and controls.

6.1 Naming Convention The Signalling Control System I/O naming convention for existing interlockings shall be as per the function names used in the circuit book or data, with the addition of an interlocking abbreviation prefix to achieve unique names. The interlocking abbreviation shall be a unique two letter abbreviation of the interlocking name.

The interlocking abbreviation is not required in the interlocking data. The function names shall omit all characters that are added to identify repeats. See Standard Signalling Circuits SDG 001, sheet Z03.

Where multiple copies of the same function are provided to the Signalling Control Systems (e.g. at system interfaces), a suffix of ‘–n’ shall be added where n is the copy number starting from 1. The suffix for the first copy of the function may be omitted; subsequent copies shall be numbered starting from 2.

The naming conventions for SSI interlockings shall be as per the SSI source files. The naming convention is defined in SSI 8003-10.

For new works the naming convention shall be as defined by this document. The naming convention of this document follows that of Signalling Documentation and Drawings SPG 0703, Appendix B ; and Signalling Circuit Design Standards Standard Signalling Circuits SDG 001, sheets Z01, Z02.

In general the indication names may exclude the ‘R’ for relay at the end of the function name. The ‘R’ shall be omitted where it is commonly omitted in usage such as track circuit indications, as is done in Microlok data. The naming convention for equipment that is not included in the above documents shall follow the name used in the signalling circuits or computer based interlockings data or is a descriptive word in brackets.

For Microlok interlockings the bit names of the Microlok data are often prefixed with their communications port number, see SPG 1230, section 4.5.3. Where this is the case, the communications port prefix shall be removed from the name used by the Signalling Control System.

The IO names may contain alphanumeric characters (case sensitive) as well as the four characters “- _ ( )”. IO names shall not contain any space characters. The asterisk ‘*’ is reserved for use by intermediate terms within the Signalling Control System. The terms “TRUE” and “FALSE” are also reserved.

6.2 Combining of Inputs Inputs shall be provided for each indication separately except where combining of inputs is required to provide the single required function such as:

a) Route availability indications.

b) Certain alarm indications as may be agreed on a project basis.

7 Expected Indications and Controls This section identifies the expected indication and control connections that shall be provided by the signalling system to the Signalling Control System.

In the table the indications specified for Relay and Microlok interfaces are expressed in terms of relay contacts. For Microlok interfaces “contact” shall mean the functional equivalent.

For SSI the table lists the indications that are required as well as the latches that need to be provided.

This table represents the usual application. Some installations may vary in the logic required to provide the function.

For example, some signals may clear without train stop drive.

The Chief Engineer Signals and Control Systems may clarify specific situations upon request.

Where separate diagnostic systems are provided, those indications that are mandatory for the Signalling Control System are noted. These may also be provided to the diagnostic system.

The indication and control listings are in Appendix A and Appendix B.

8 Spare Indications or Controls Controls and indications shall be logically (numerically) arranged in order on the serial links. It is preferred that any new or altered spare indications or controls are added to the end of any listing rather than to readjust the predefined order in the bit stream. Once the bit listing is established minor modifications may have the spares at the end utilised for additional bits.

To facilitate the addition of extra bits, the listing shall include the initial allocation of an additional 15%– 20% bits nominated as spare over & above the required bit listing. Typically the additional spare bits may fill out the capacity of the addressing arrangements.

9 Allocation of Indications and Controls All indications and controls related to an item of signalling equipment shall be allocated in one telemetry system. For example all the IO for a signal including all indications and controls as well as associated A track indication for all routes from the signal shall be allocated to one telemetry system.

Indications shall be geographically contiguous in one telemetry system, i.e. If the signal and A track are indicated from System 1 and the B track is indicated from the next telemetry (2) then subsequent tracks C, D, etc. shall be indicated from system 2.
