## System Design and Configuration 

Automation system will have structure which is suitable for extension. Software to be offered should use windows based datatabase of which graphical interface and logical interface software are single. Also software will create all variables, alarms, trends and control blocks (motor and pump) and faceplates automatically from relevant library and will submit report. 

## Single software environment 

Single software environment is compulsory. No package with software which are dependent with each other will be accepted. Software medium should be suitable for major and minor applications without requiring other software medium. Single medium should cover applications design, topology structure for control, operator screens, hardware configuration(controller, rack and remote I/O, network, field communication, operator screens) 

## Object Model 

System should rely on objects which are inspired from real world. Software should maintain data to be created automatically in control and operator interfaces when object is created in application. Software should allow user to create new object and make modification over objects within library. 

## System Design 

User should be able to design process as hierarchical tree. System software should allow easy way for adding object in configuration mode rather than programming. User interface should be maintained for adding object(valve motor etc..) without requiring deppd programming knowledge. 

## Operator Interface 

Operator interface to be used in system will consist of 2 servers, 2 clients and 1 client with license for 1250 object. Servers will work as redundant. When of these licensed clients shut down or has failure it will be able to retrieve data from other server. Properties regarding with operator interface also mentioned below. 

Operator interface software will write data over field control devices for easy and fast implementation of operation and maintenance of system by operators, controllers and maintenance personnel, will read data from these equipments, will archive and monitor historical data and will provide graphical screens and reports. 

All operator interface functions such as communication drivers, graphical properties, reporting, storing historical data, trend and alarm indicators, and development mediım are expected to be delivered as integrated software package or package set. If software has to be supplied from more than one vendors for meeting this specificatipn, software components and dealers should be given as separate list. 

In addition to this, Party and Solution management, material tracking, calculation of non operation period and similar management reporting and OEE and similar top level software products will be purchased from Operator interface dealer as single software package or integrated packages. 

Operator interface software will write data over field control devices for easy and fast implementation of operation and maintenance of system by operators, controllers and maintenance personnel, will write data to these equipments, will archive and monitor historical data and will provide graphical screens and reports.
