(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) enclosed with this specification. Client-server
based architecture will be considered for automation. Contactor will
submit configuration diagram of the automation system provided by
them accordingly. Requirements of Controllers & their division, Work-
stations/Servers, Engineering stations, Printers etc. will be indicated in
the configuration drawing.
12. Automation system of proposed plants will have three level Ring
Architecture type communication buses as follows :
a) HMI-level Ethernet for HMI Stations, MIS Servers, MIS Clients,
Higher-level systems etc. Contactor to provide for CSP in line with
Automation Configuration drawing.
b) Control-level Ethernet for connecting PLCs, Servers, Emergency
Work Stations, Engineering Stations etc. Contactor to provide for
CSP in line with Automation Configuration drawing.
c) I/O level communication bus. Contactor to provide for CHP & CSP
in line with Automation Configuration drawing.
13. 1 No. field programming unit for CHP, 2 Nos. field programming units for
CSP and 2 Nos. field programming units for Augmentation in Flux - Fuel
Preparation and Plant Return Fines Handling For SP III will be in the
scope of Contactor. Apart from standard features, these field
programming units will be capable of connection from every Remote I/O
station for engineering and troubleshooting purposes.
14. 2 Nos. MIS servers each will be included in the Automation system of
CSP and Augmentation in Flux - Fuel Preparation and Plant Return
Fines Handling for SP III.
15. All printers provided with PCs will be laser jet type.
16. The design will be done in such a manner that involvement of cabling
and wiring is minimum.
17. All the automation equipment will be configurable to a user configurable
fail-safe state to avoid dangerous situations in case of any failures due
to power failure, communication failure etc.
18. Different levels of networks will be inter-connected through intelligent
devices which are capable of high speed switching at least at Layers 3 &
4 with access control. For all important systems firewall will be provided,
taking care at Layers 3 to 7.
19. Temperature monitoring of all remote I/O stations will be provided
through respective PLC.
