Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Section 8: Electrical Works  77 of 124   Monitoring, reporting, distributing and acknowledging alarms   Collecting, storing and distributing historical trends   Processing, storing and distributing reports   Internet services for internet browser based clients. Subsystems should be designed as separate series where one subsystem will not effect operations of  other subsystem adversely and subsystem which generates error should be able to be reset and  recovered without closing computer or application. This will maintain to store all historical records in  central pool for preventing process doubling, reducing network bandwidth and field device operations  and maintenance and repair operations. Operator interface which is recommended for managing different stations where test, development,  operation, local monitoring, remote monitoring and maintenance operations should support following  Microsoft ® operation systems   Windows$^{®}$ 8.1 Pro or 10   Windows Server® 2008   Windows Server® 2012   32 and 64 Bit  Operator interface was designed for supporting all development and operation applications at same  time. Operator interface should support application of all combinations for operation systems which  are mentioned above. For example Operator interface should be able to be implemented in Windows  Server 2012 platform, clients in Windows 10 pro or Windows 8.1 Pro Platform and development  should be able to be applied in Windows platform. Also system should support ordinary Internet browser based clients for providing personnel who is  present in WAN with proper security configuration to access to system. Internet browser clients  should support view and control properties which are controlled by both login security and license  types. Internet browser client should provide including but not limited to graphical screens, trend  pages, alarm pages and system security for standard client software. Internet browser clients should  support view and control features which are controlled by both login security and license types.  Internet browser client should not require additional design or customized software for exporting  configuration. Operator interface should be able to be configured as single global database notwithstanding with  number of stations within system. User should be able to make configuration modifications over  global database in station within system provided that all operations are transparent. Each operator  interface should have option for remote accessing to database in file service medium in networks  which have local storage or high bandwidth capacity. Operator interface should be able to be configured as series of project for facilitating maintenance and  commissioning and it should be interconnected (or intranet) for providing to work as single global  database. All server based software tasks will be present in primary and standby computers for each task. Also  software will support smart full redundancy property. Thereby there should be not only reproduction  but also uninterrupted back up property for providing uninterrupted and trouble free operation in any  hardware or software failure in subsystem and for copying operator processes from one server to other  without requiring any additional configuration or code. 8_Vol3_d4.3_Section 8 electrical works_en_GIR.rev8.doc
