72 of 124  Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Section 8: Electrical Works  The CMS shall be provided with all hardware and software necessary for the operation including  cables, modems, interfaces etc.  Automation system where plant can be controlled and commanded over central Operator Interface  Computer will be designed(As hardware and software)  Supply, installation and configuration or control interfaces which are close to field, local control room  interfaces, local instrumentation interfaces, works for supplying energy for these and all kind of cable  and additional hardware works for those. Control Panel for (CMS/PLC) for processing manually handled control commands and monitoring  process, Local instrumentation boards and buttons for these panels, indicator lamps and all other  necessary equipment and parts. Supply, installation and commissioning will be implemented for Ethernet and necessary cables for  maintaining communication between Controller/CMSs and Operator interface within plant.  Communication infrastructure to be installed will have Ethernet based structure with ring topology. In  case of line disconnections System will continue to work without interruption in communication due  to ring structure. CMS; Controlling and monitoring system   GENERAL  Any kind of Controller/CMS equipment, License of programs which are used in Operator  Interface/SCADA and HMI (Operator Panel) which are supplied by tenderer, software and programs  will be delivered to enterprise at the end of work. Documents regarding with each equipment,  necessary programming software which is necessary for operation of automation system will be  delivered together with system including spare parts. Plant will be controlled and commanded by Controller/CMS, Operator Interface and HMI system  within scope of project. Controller/CMS, Operator Interface and HMI system will consist of CPUs,  input/output units, communication modules and cables and industrial switches. Communication  between Controller/CMS, Operator Interface and HMI (Operator Panel) will be Ethernet  communication and will communicated with existing and to be installed control structures. Controller/CMS,I/O cards remote controllers, Operator Interface, reporting, HMI, Operator Panel and  Industrial switches will be same brand for system reliability, responding rapidly, storing spare parts  and not to have failure for long time period. Controller Technical Specification: AUTOMATION TECHNICAL SPECIFICATION   It will be controller structure which will be required for controlling, commanding and  monitoring system and it will be installed. All data exchange with CPU will be made with  minimum impact during cycle time period in each data scanning time period. TCP/IP with  minimum 100 Mbits/s will be used for communication between HMI (Operator Panel) and  Operator Interface/SCADA system.  Data which are acquired from field (Digital and Analog) or signals which are sent from CPU  for control will be received from or transferred from Remote I/O(Input/Output) cards and will  be communicated to CPU by this manner. CPUs and Remote I/O structures will have same  brand depending on system and process structure.  I/O cards which are present in system will have hot swap ( installed and removed under  energy) in all rack(backbone structure). Also system will remain in RUN mode while  8_Vol3_d4.3_Section 8 electrical works_en_GIR.rev8.doc
