The scope of work and supply will include but not limited to the following:
1. Automation system as per the facilities indicated in the Automation
System Configuration diagram (Drg. No: MEC/S/9101/11/E9/55/01/
064.01/R1) for CHP & Drg. No: (MEC/S/9101/11/E9/55/01/064.02/R1)for CSP
and (Drg. No: MEC/S/9101/11/E9/55/01/064.04/R3)MEC/S/9101/ 11/E9/0/00/00/
064.04/R3 for Augmentation in Flux - Fuel Preparation and Plant
Return Fines Handling for SP III and as described in ‘General’ and
‘Salient Features of CHP, CSP and Augmentation in Flux - Fuel
Preparation and Plant Return Fines Handling for SP III’.
a. For CSP this will mainly include independent PLC systems with
redundancy in: - processors, power supply modules,
communication modules, network interface modules, MIS servers
etc. for plants/units. Number of operator’s station and engineering
work station shall be as automation configuration diagram.
Communication bus will be ring architecture type. The automation
system will be client-server based configuration. All the required
facilities & features for interfacing of PLC systems will be
considered and provided accordingly.
b. For CHP, the Contactor will provide PLC based automation
system, with redundancy in:- processors, power supply modules,
communication modules etc in line with GTS. Number of
operator’s station and engineering work station shall be as
automation configuration diagram. Remote I/O stations, I/O Level
communication Bus, necessary gateway (associated hardware
and software) for interfacing with employer Automation network,
Engineering station, HMI shall be as shown in Automation
Configuration drawing.
c. For Augmentation in Flux - Fuel Preparation and Plant Return
Fines Handling for SP III, the Contactor will mainly provide PLC
based automation system, with redundancy in :- processors,
power supply modules, communication modules, network
interface modules as per GTS. Number of operator’s station and
engineering work station shall be as automation configuration
diagram. 0perator’s and engineering workstations, Remote I/O
stations, I/O Level communication Bus, Control-level bus,
necessary gateway (associated hardware and software) for
interfacing with employer Automation network, Engineering
station, HMI shall be as shown in Automation Configuration
drawing.
2. Required nos. of local/remote I/O panels with adequate quantity of
various types of I/Os cards, i.e. Digital, Analogue, RTD,
Thermocouples, Pulse, power supply cards, communication cards,
Relays with NO contacts for outputs etc. at different locations.
