K 15-16.2 Scada System.

Tenders are invited for K 15-16.2 Scada System

TECHNICAL SPECIFICATIONS

1.0.0 SCADA SERVER HARDWARE & SOFTWARE

1.1.0 HYPER SCADA SERVER

a) The Hyper SCADA Server (HSS) shall be a self-contained data collection and information server

housed in a wall-mounted enclosure. It shall use a Modular Backplane for power distribution and

modularity. The HSS shall contain dual CPUs for Hot-Standby Redundancy, network switchgear,

fiber optic converter, power supply units, backup batteries, and surge protection.

b) The HSS shall be wall mounted in a climate-controlled facility. The HSS enclosure shall feature a clear window on the front door to allow observing of status LEDs without opening the door.

c) The HSS shall connect to a Primary Workstation Computer via a direct Ethernet connection. This

direct connection permits Primary Workstation Computer access to the HSS should a separate local area network (LAN) experience a failure. The Primary Workstation Computer will be designated as a data back-up location. The owners personnel shall be able to sign onto the system from properly configured workstation computer(s) connected to the HSS via a network or phone line connection.

1.2.0 HYPER SERVER MODULE

a) The Hyper Server Module (HSM) shall be an embedded computer that includes a CPU, memory,

storage, two on-board voice-grade modems, and network interface.

b) All communications to and from the HSM shall be through the network connection and modulemounted modems.

c) A button shall be provided to direct the CPU to an orderly shutdown process. Status LEDs shall be provided to indicate CPU activity and system status. Configuration straps at the card edge shall be provided to enable system-level configuration. Replacement of an HSM shall not require the use of tools and shall be nothing more than changing the module in the card edge connector.

1.3.0 COMMUNICATION PROTOCOLS

a) The communication protocols supported by the system shall include: 1) TAC II Radio, 2) DFP Radio,

3) Net-DFP, 4) MODBUS ASCII, 5) MODBUS RTU, and 6) MODBUS TCP.

b) The HSS shall be capable of simultaneously polling multiple communications links.

c) All RTUs utilizing TAC and DFP protocols shall have the capability of being used as a digipeater for relaying messages from the HSS to any other RTU. The response messages from the destination

RTU shall be digipeated to the HSS by the same RTU that forwarded the message to the destination

RTU. Mapping of digipeating shall be user-configurable from any workstation computer. Modifications or programming at the RTUs shall not be required. Four (4) levels of digipeating shall be supported.

d) The system shall be capable of utilizing up to 505 radio addresses per communications link, and up to 15 function modules per RTU.

e) All remote interfaces directly connected to the HSS shall be fiber optic isolated for transient voltage protection. etc.
