subsystems. Status reporting, information storage and retrieval, alarm processing,

trending and incident and operations reports shall be provided via overhead

displays, ROC consoles, archive media drives and hard disc storage.

As a part of initial system sizing, the SCADA system shall be provided with the

processing capability and memory required for Rail Projects, including

communication circuits, application programs, database, displays, and logs. The

system shall permit database generation and changes, as well as the compiling,

debugging, and integration of new software. Schematic, one-line, pictorial, and

alphanumeric displays shall be generated, altered, or deleted on-line by use of

interactive programs and LCD terminal keyboards. All application programs shall be

implemented with the capacity for all Rail Projects. The SCADA system shall be

designed for ease of expansion and alteration in an economical and efficient

manner, to facilitate future Rail Projects.

The maintainable system life of the SCADA system shall be at last 25 years.

9.11.2. Functional Requirements

1. The SCADA subsystem shall facilitate the transmission of indications and

alarms from the remote terminal units (RTUs) to the ROC and the

transmission of controls from ROC to the RTUs. All transmissions shall be

through the CTS. The SCADA transmissions shall include:

a. Traction power alarm indication and control signals

b. TC alarm, indication and control signals

c. Mechanical equipment, load shed control signals and auxiliary power

alarms

d. Fire detection signals

e. Tunnel ventilation alarm, indication and control signals

f. Communications alarms

g. Miscellaneous electrical/mechanical system status and alarms.

h. Any other interfaces and capabilities required for safe, efficient, and

effective remote operations.

i. All Communications systems control, status/indications and alarms;

j. Passenger station subsystem alarm, indication and control

2. Remote terminal units (RTUs) – See Appendix A - shall be provided to

interface local and remotely located devices with the SCADA subsystem.

Analog input, contact inputs, contact output and local subsystem

communications interfaces shall be provided. The RTU shall provide

isolation between the signal source and the CTS units. The preferred design

is IP based communications (See Appendix B).

3. Redundant server processors shall be provided and configured in a

primary/backup mode to support automatic fail over to the backup processor

upon failure of the primary processor.

4. Signal transmitted from the RTUs to the processors at the ROC shall be

processed to provide monitoring information to all subsystems listed above,

generate commands to be transmitted back to the RTUs, provide information

for displays and alarm processing at the control consoles and store

information and historical data for future processing.
