Contactor will also consider input interposing relays for field mounted
proximity switches in the I/O chassis.
3. Preferred Makes of individual equipment i.e. PLC systems,
Workstations, Servers, Engineering stations, printers etc., will be in
line with GS-13. All the Hardware in Individual Systems will be from
the same product series.
4. All required software i.e. System software, HMI software, Application
programmes etc. for PLC, Workstations, Servers, communication
interface amongst various automation systems etc. Required number
of software licenses will also be provided.
5. All maintenance, diagnostic tools & devices required for
implementation, maintenance & trouble shooting.
6. 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.
7. All Network components like Gateways / interfacing modules, cables,
multi-port switches (if applicable) etc., as required for interfacing.
8. Optical Link Modules, Light Interface Unit, Redundant link modules,
Power supply Cards, Converters, Terminators etc. as per
requirements.
9. Other than the PLC systems specified in the configuration diagram, if
any separate PLC systems are required for operation of the auxiliary
units of the proposed CHP, CSP and Augmentation in Flux - Fuel
Preparation and Plant Return Fines Handling for SP III the same will
also be offered and suitably interfaced with the main automation
system.
10. All types of system cables, communication cables, LT power cables,
special cables, etc., as required. This will also include the required
communication interface and cable for interfacing with the PLCs of
conveying system of COB#11, Blast Furnace Stock House, Sinter
Plant, CDCP etc. (as described in ‘Interfacing’ in CTS), located at
respective control rooms.
11. Necessary co-ordination with employer / Mecon for establishing
interfacing and integration requirement by providing new PLC,
multiplying relays as required, interconnecting cabling between
employer’s MCC/ other panels and Contactor’s PLC/ Remote I/o
stations etc.
