4.0 PMCS Overview

4.1 IntroductionThe PMCS will be formed as an autonomous monitoring and control system allowing all monitoring

and control operations to be performed locally to the tunnel.

The PMCS will be configured as a hierarchical distributed system, consisting of the following

monitoring and control layers:

Supervisory Control and Data Acquisition (SCADA) servers, incorporating the Graphical User

Interface (GUI)

Central supervisory control Programmable Logic Controllers (PLC’s)

Distributed outstation PLC’s associated with plant requiring local control functions, such asthose at local control panels

The provision of layered hierarchical monitoring and control will provide the following benefits:

Partitioning of monitoring and control capability to appropriate operating personnel

throughout the infrastructure

Reversionary monitoring and control capability in the event of incident

Ability to commission and maintain assets independently of the complete infrastructure

The SCADA Servers will be configured as a dual hot-standby pair.

The supervisory control PLC’s will be configured as a dual hot-standby pair.

Other PLC units will be configured in a dual hot-standby pair, where required, in order to provide a

highly reliable and available system, otherwise a singular unit will be employed connected to either

the A or B ring network.

SCADA Server, supervisory control PLC, PLC, and RIO units will be interconnected by a dual

redundant control network, in an A and B configuration.

The SCADA/PMCS will contain a separate logic programming emulating an interface window , named

the Tunnel Subsystem, which will interface with the TMC tunnel operator desk, for the remote

interface and control in respect to the traffic control aspect of the tunnel operation.

4.4 Supervisory Control PLC’s

The supervisory control PLC’s performing overall management of the outstation PLC’s and RIO units

of the PMCS, including functions such as the following:

Overall system control

System moding

Interfacing with the GUI

Outstation PLC and RIO unit monitoring and control

Data acquisition management

System health monitoring

System alarm monitoring

Communications with Traffic Management Centre (TMC

The supervisory control PLC’s will be configured as dual industrial-grade PLC’s operating in hot-

standby mode.

4.5 Outstation PLC’s

Outstation PLC’s will be used where control functionality is required to be distributed within the

tunnel such as, for example, for the management of Smoke Control Panels (SCP’s).

Outstation PLC’s will be configured as dual industrial-grade PLC’s operating in hot-standby mode.

4.6 Dual configuration

Master-standby arbitration and selection of the supervisory control PLC’s will be achieved through

the use of external *with respect to the PLC’s+ hardware watchdog timing circuitry. Such a hardware-based approach will provide much greater determinism of mutual exclusion of mastery.

Upon system start-up one of the supervisory control PLC pair, arbitrarily selected, shall automatically

be configured as the master, assuming control of the PMCS.

The master-standby state of the supervisory control PLC’s will be used to derive and determine the

master-standby configuration of other dual configuration units throughout the PMCS, thus removing

the need for additional master-standby arbitration hardware in each instance of dual configurations

throughout the system.

External hardware-based watchdogging will be used to monitor the supervisory control PLC’s for

failure, in which case mastery will be allocated the standby unit.

Software-based heartbeat watchdogging will be employed by the supervisory control PLC’s to

monitor the health of other dual configuration units throughout the PMCS, and allocation of mastery

performed accordingly.

The dual configuration scheme will transparently implement the following dual configuration

functions:

Replication of the processing context to the standby, including programs and data

Detection of faults and switchover

Integrity Level (SIL) 2 and a validation process shall be carried out confirming the criteria reached,

i.e. SIL2.

4.11 Control Network

The PMCS processing and I/O units will intercommunicate control and data via a dedicated dual

redundant Ethernet-based control network.

The PMCS control network will be formed of multi-mode fibre optic and copper segments, as

required.

The backbone of the PMCS control network linking central control units to outstation units will be

two fibre optic circuits, each arranged in a ring topology to form two independent ‘A’ and ‘B’ closed-

loop self-healing networks capable of continued operation in the event of a fibre-optic cable

disconnection or network switch failure.

The dual supervisory control PLC’s will each be provided with dual connections to both the ‘A’ and

‘B’ control networks, thereby providing resilience in the event of failure of one of the supervisory

control PLC’s.

Each PMCS outstation processing and I/O unit will be provided with a single connection to one of the

‘A’ or ‘B’ networks. At outstation locations where dual redundant processing and I/O units are

deployed, then each of these will be provide with a single connection to the ‘A’ and ‘B’ control

networks; one unit to the ‘A’ control network and one unit to the ‘B’ control network.

The dual SCADA Servers will each be provided with a single connection to the ‘A’ or ‘B’ control

networks; one to the ‘A’ control network and one to the ‘B’ control network.

The PMCS will use Ethernet-based Open Process Control (OPC) protocols for internal and external

communications.

4.12 Instrumentation Interface

Within 4 No. SCP’s outside each portal (Dual configuration)

Within 8 No. EDP’s within each bore (16 In total, single configuration interleaved)

In the midpoint sump plant room, (Dual Configuration)

4.15 Power Supply Redundancy

Dual configuration PMCS Server and PLC processing units will be fed through the UPS system and

parallel power supplies to ensure that failure of a single supply does not induce a common-mode

failure to redundant equipment.

4.16 Capacity Sizing

The PMCS will be capacity sized to accommodate the requirements of the outline design detailed

herein. Furthermore, allowances will be made for additional capacity, as follows:

I/O intrinsic average spare capacity: 10%

I/O spare capacity by addition of modules: 25% I/O spare capacity by addition of subsystems: 50%

PLC Processor capacity by addition of spare capacity: 100%

SCADA Server disk/processing spare capacity: 200%

5.0 General Monitoring and Control Scheme

5.1 Data Acquisition

The PMCS performs logging of all data point values acquired or derived into a historical database.

Log entries will provide the following information:


21/40


Specification


Rev. D02

Time stamp of entry

Date stamp of entry

Identity of the data point Data point value with scaling

Data point transmission through the PMCS will be optimised with respect to update rates and data

push/pull configuration in order that:

Valid and current data is always available throughout the system

Data currency is always deterministic

Throughput on the transmission infrastructure is optimal

The transmission infrastructure can accommodate worst case data-burst situations,

particularly in non-normal scenarios.

The dual supervisory control PLC’s will independently gather all data from local sources regardless of

master-standby status. This approach will provide validation that each main supervisory control PLC

has an active communication link with the outstation devices, and will maintain data currency

allowing hot-swap to the standby in the event of failure of the master unit.

5.2 Alarm Monitoring

The PMCS will monitor all controlled plant for alarm conditions, including PMCS-internal fault

conditions.

The following alarm conditions will be monitored, as follows:

Alarm indications generated as a result of detection of conditions external to the PMCS. The

nature and extent of such alarms will be determined during subsequent design stages, but

are likely to include sensing of out-of-band parameters, i.e. physical measurements outside

their expected range.

Alarm indications generated as a result of detection of conditions internal to the PMCS. The

nature and extent of such alarms will be determined at subsequent design stages, but are

likely to include sensing of failure of control system processors, and the like.

Alarm indications will be filtered and stored by the PMCS.

Filtered alarm indications will be transmitted to the TAO/TMC for remote condition monitoring.

Two forms of alarm and fault monitoring mechanisms will be provided, as follows:

Active reporting by exception, whereby the plant and PMCS elements will signal alarm and

fault conditions detected

Polled monitoring by PMCS, whereby the active control elements of the control system will

intercommunicate periodically in order to determine the ‘health’, i.e. the correct operati on,

of the control system itself.


22/40


Specification


Rev. D02

Alarm indications will be ranked by importance/severity and displayed via the SCADA Tunnel

Operator Terminal (GUI) such that conditions are displayed in different modes according to the

condition severity and the operating privileges of any user logged on to the system.

Alarm indications will be recorded in a historical database for subsequent analysis. Log entries will

provide the following information:

Time stamp of entry

Date stamp of entry

Description of the alarm condition

5.3 Control and Data Flows

The dual supervisory control PLC's will receive control commands from the SCADA Servers and will

derive their own responses to these commands. The supervisory control PLC designated as master

will be configured to issue demand outputs to the tunnel plant. The standby supervisory control PLC

will be inhibited from issuing demand outputs.

The master and standby supervisory control PLC’s will replicate commands and data between them

in order that the processing context of both units remains synchronized, allowing hot-swap to the

standby in the event of failure of the master unit.

The SCADA Servers and TSS application will request data only from the supervisory control PLC that

is designated as master.

Dual configuration outstation PLC's will both transmit data to both supervisory control PLC’s.

Inputs from plant to dual PLC units will be read from PLC units and will be combined into a common

data set. In the case of data mismatch the worst-case plant condition will be reported.

Outputs to plant from dual RIO units will be configured so that either PLC device can operate the

plant by paralleling of outputs, thereby ensuring continued / fail-safe plant operation in the event of

failure of a single PLC unit.

5.4 Control Modes

The PMCS will provide a range of control modes to suit the operational requirements of the tunnelenvironment.

The supervisory control PLC’s will accept requests for selection of control mode and will arbitrate

these requests in order to activate the highest priority control mode.

The following general control modes/sources will be provided ranked in increasing priority order:

Automatic

Automatic control mode is the default control mode and is always active, although possibly over-

ridden by a higher priority control mode. Automatic control mode demand is derived from plantsensor levels and states, set-points, and control parameters. Automatic control mode demand will


23/40


Specification


Rev. D02

always be derived and presented to Operators, regardless of the actual control mode active, thereby

providing the operator with visibility of the automatically calculated demand.

TMC Traffic Control operation through the TSS application

TOA Tunnel Operation control relates to operator control and demand selections from the

TMC Tunnel Operator interfaced via the TMC control stations and Network.

Engineering Terminal

Engineering Terminal control relates to operator control and demand selections from

engineering/maintenance terminals connected at any location on the PMCS network

infrastructure, and normally present at the TMC

SCADA GUI application

The SCADA GUI application is the primary source of system control moding', and is located

within the Tunnel Services Building (TSB).

Smoke Control Panels

These control mode selections will be requested from the SCP’s. Arbitration of control

requests will be performed in the event that both SCP's are accessed at the same time such

that only one Smoke Control Panel can issue commands at a time.

Local Plant Control

Local plant control will be affected by direct operation of individual items of plant and/or their

associated autonomous control systems via plant-local control panels. The PMCS will continue to

monitor locally controlled plant and generate control demands wile local plant control is active; in

order that seamless transition of control may be achieved once local plant control is relinquished.

Additional control modes specific to particular tunnel systems will be provides, as required, and

these are described herein within the sections detailing the control schemes for specific tunnel

systems.

5.5 Running Hours and Plant Metrics

The PMCS will acquire/derive and store data relating to the running time of plant, as well as other

metrics required to assist the effective and efficient plant maintenance. Data to be a

acquired/derived and stored includes the following:

Plant running time in hours

Plant duty cycle

Plant failure instances

Plant failure instance periods

The PMCS will provide the ability to reset metrics for individual items of plant.

5.6 Signal Conditioning

The PMCS will implement a scheme of signal conditioning and scaling that ensures that data is

transmitted, stored, and manipulated in a uniform and consistent manner.

Where required, digital inputs will be conditioned by pulse stretching in order that fast switching

signals are detected correctly

Where required, digital inputs will be conditioned by de-bouncing in order that switch selections and

the like are read correctly.

6.0 Tunnel Lighting System Control Scheme

6.1 Control Scheme Overview

The PMCS will provide a range of control modes to provide efficient and effective control of the

lighting system.

The PMCS will accept requests for selection of control mode and will arbitrate these requests inorder to activate the highest priority control mode.

Control modes that will be provided, ranked in increasing order of priority, are as follows:

Automatic

Manual Operator Override from TMC/TSS

Manual Operator Override from TOA/SCADA GUI

Manual Operator Override from SCP

Manual Operator Override from Lighting Control Panel (LCP)

Automatic control mode is the default control mode, and is always active, although possibly over-

ridden by a higher priority control mode

The manual operator override control modes provide an Incident Control sub-mode that allows

lighting level change demands to be actioned with reduced rate-of-change constraints, thus allowing

more rapid changes in lighting levels to be achieved.

Lighting control will be achieved via an autonomous Lighting Control System (LCS). A LCS will be

provided for each tunnel bore. Each LCS will be provided with a local LCP. The PMCS will interface

with the LCS, generating demands for lighting levels and monitoring LCS and lighting system status.

The Manual Operator Override from LCP, also known as Ancillary Local Manual Control, control

mode will be provided by the LCS

6.2 General Lighting Control Scheme

The LCS will control the tunnel lighting automatically based upon photometer sensor readings.

Two external photometers will be provided at the stopping distance from each tunnel bore entrance

portal, and the average reading of these will be used by the LCS to calculate a lighting level demand

for each tunnel bore.

The LCS will support seven stages of lighting, with stage 1 providing the lowest level of illuminationand stage 7 providing the highest level of illumination, this representing 100% of total possible


25/40


Specification


Rev. D02

lighting system output. The LCS will convert photometer sensor readings into a demand for lighting

for stages 1 through to 7.

The LCS will integrate photometer sensor readings in order to filter fast rate of change

environmental effects upon the sensors, thus avoiding rapid and spurious lighting level changes.

The LCS will sequence through lighting stages with a set-point limit period between stage transitions

in order that gradual changes in lighting levels are achieved, with an associated reduction in peak

inrush currents. An Incident Control Mode will be provided by the LCS in which the limit period

between stage transitions is reduced so that more rapid changes in lighting level may be made.

The LCS will detect lamp failures and switch in additional units to compensate and maintain lighting

levels.

Threshold zone luminance will track the L20 luminance measured by the external photometers. The

threshold zone luminance will maintain 7% of the L20 value.

Transition zone luminance will track the threshold zone luminance and will vary along the length of

the zone following the reduction curve defined in BS5489-2.

Exit zone luminance will be as defined in BS5489-2.

Emergency lighting levels will be in accordance with BS5489-2 and BS EN 1838:1999, taken to be the

greater of the required level for stage 2 lighting or 15lux.

Lighting stages 1 through to 4 will be backed up by Emergency Standby Generator, with UPS support

for stage 1 and 2 lighting to cover the period of generator start-up. Failure of the Emergency Standby

Generator to provide a supply within 5 minutes of a demand will result in reversion to emergency

lighting levels, which will be maintained for at least 2 hours via the UPS.

6.3 Automatic Control Mode

In Automatic control mode the LCS will autonomously control the lighting levels within each tunnel

bore based upon external photometer sensor readings.

The automatically calculated lighting stage demand, and the currently active lighting stage for each

tunnel bore will be monitored by the PMCS, and this will be displayed on the SCADA GUI and

recorded by the SCADA Servers. This will give the Operator visibility of how the lighting control will

change when higher priority control modes are de-activated and lower priority control modes

become active.

6.4 Manual Operator Override from TMC Control Mode

The PMCS will accept Manual Operator Override from TMC control mode demands for each tunnel

bore. These demands will be for lighting stage 7 only.

The Manual Operator Override from TMC control mode will remain active until the PMCS receives a

control mode reset command from the TMC.


26/40


Specification


Rev. D02

The SCADA GUI will provide a password-protected manual operator override control mode reset

function in case it is not possible for the TMC operator to issue a reset command due to TMC

communications link failures, and the like. The use of this function will be recorded by the SCADAServers for auditing purposes.

6.5 Manual Operator Override from SCADA GUI Control Mode

The PMCS will accept Manual Operator Override from SCADA GUI control mode demands for each

tunnel bore. These demands will be for lighting stages 1 through 7.

The PMCS will request the LCS to activate the lighting stage demanded by the operator. The LCS will

arbitrate the PMCS lighting stage demand, only selecting for activation demanded lighting stages

greater than the lighting stage demand calculated automatically by the LCS. Lighting stage demands

rejected by the LCS will be displayed by the SCADA GUI and recorded by the SCADA Servers.

The PMCS will provide an Incident Control Mode that will allow the PMCS to request the LCS to

activate the demanded lighting stage with reduced transition times between lighting stages in order

to allow more rapid variations in lighting levels to be achieved.

The Manual Operator Override from SCADA GUI control mode will remain active until the PMCS

receives a control mode reset command from the SCADA GUI.

6.6 Manual Operator Override from SCP Control Mode

The PMCS will accept Manual Operator Override from SCP control mode demands from for each

tunnel bore. These demands will be for lighting stages 1 through 7.

Four smoke control panels will be provided, situated at the portals, one per entrance and exit to

each tunnel bore.

Lighting control via the SCP’s will be arbitrated on a ‘first -come, first-served’ basis such that once an

SCP has been granted control for a tunnel bore the other SCP’s will be locked out from control of

that tunnel bore for the duration of the control selection being active.

SCP’s will provide the following lighting-related controls and indicators for each tunnel bore:

Request/relinquish local manual control selection control : 1 input latching toggle Local manual control active indicator

Currently selected lighting stage indicator: 7 stage indication from stage 1 to stage 7

Requested lighting stage increment/decrement demand control: 2 input control with senses

of ‘increment’ and ‘decrement’

Incident control demand control: 2 input control with senses of ‘on’ and ‘off’

The PMCS will request the LCS to activate the lighting stage demanded by the Operator at the SCP.

The LCS will arbitrate the PMCS lighting stage demand, only selecting for activation demanded

lighting stages greater than the lighting stage demand calculated automatically by the LCS. Lighting

stage demands rejected by the LCS will be displayed by the SCADA GUI and recorded by the SCADAServers.


27/40


Specification


Rev. D02

The PMCS will provide an Incident Control Mode that will allow the PMCS to request the LCS to

activate the demanded lighting stage with reduced transition times between lighting stages in order

to allow more rapid variations in lighting levels to be achieved.

The Manual Operator Override from SCP control mode will remain active until the PMCS receives a

relinquish control command from the SCP.

6.7 Manual Operator Override from LCP Control Mode

The Manual Operator Override from LCP control mode will be provided by the LCS.

A local control panel will be provided, adjacent to the LCS at the TSB.

The Manual Operator Override from LCP control mode will remain active until relinquished at the

LCP.

6.8 Lamp Status Monitoring

The TPM&CS will continuously monitor the LCS for the status of the tunnel lamps, segmented into

tunnel zones. The following information will be displayed on the SCADA GUI and recorded by the

SCADA Servers for each tunnel zone:

One or more lamp/ballast failures present

One or more lamps in maintenance override

6.9 Emergency Standby Generator Load Shedding

The PMCS will inform the LCS that lighting stages in excess of stage 4 lighting cannot be exceededselected when the Emergency Standby Generator is active in the event of supply failure.

The PMCS will inform the LCS that lighting stages in excess of stage 2 lighting cannot be selected

when the Emergency Standby Generator has failed to become active on demand in the event of

supply failure, and lighting is therefore supported by UPS only.

7.0 Fire Safety Systems Control Scheme

7.1 Emergency/Electrical Distribution Panels Control Scheme

Emergency Panels (EP's) and Emergency Distribution Panels (EDP's) will be provided with limit

switches to allow the detection of the following conditions:
