75 of 124  Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Section 8: Electrical Works  System Design and Configuration  Single software environment  Object Model  System Design  Operator Interface  8_Vol3_d4.3_Section 8 electrical works_en_GIR.rev8.doc  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. 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. 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. 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. 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. 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. 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. 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) 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.
