ANNEX - 2 SYSTEM ACCEPTANCE

1.0 The contractor shall arrange to conduct a System Acceptance Test. 2.0 The criteria for acceptance of the SCADA system shall

include the successful demonstration of all the functions and features of the proposed system. 2.1 The following system parameters are to be successfully demonstrated for system acceptance:

1. Availability of automation system : >99.9% 2. Network bandwidth utilization

(Average) (To be measured over continuous period of 8 hrs)

: <20%

3. Spare I/O capacity of each type : >20% (after commissioning) 4. Spare capacity of network switch

ports of each type : >20% (after commissioning)

5. UPS spare capacity : >20% (after commissioning) 6. UPS battery back-up time : 60 minutes

2.2 Availability of the SCADA system (i) For the test purpose of assessing system availability the

SCADA system will be operated continuously for a period of seven (7) days. (ii) Availability calculation

The above mentioned system availability will be calculated as follows:

System Availability = Total Test time - Total down time x 100% Total Test time

25331-00-08-ELA-001

26 of 31

The total down time shall be calculated using the following co-efficient for each device. Device Co-efficient 1. Server hardware : 100% (For redundant

servers if both the primary and secondary servers are down)

2. HMI / Engg. Station hardware

/printer : 15%

3. Networking equipment : 50% 4. Application software failure : 100%

Total down time calculation Total down time = Σ ( ti * ei) Where ti : Down time of individual device ei : Coefficient
