TECHNICAL DESCRIPTION - Finishing of the existing PLC program and system for visualization of the plant for steam production in Studen Agran Factory. - Delivery of new PC operating cell with 19’’ monitor with minimal characteristics: 2GHz dual core, 1GB RAM, HDD 100Gb, HMI Software (WiCC v7.0) and license for HMI software for OS cell. - To align working algorithm of the existing PLC program with the technological P&D diagram and control sequences. - Modify software regulators in PLC program so as to existing SIPART regulators could be scrapped. - Managing with spreader rollers (3 pieces) change in the sense that controlling is done individually instead of the current group control with all three drives at the same time. - Modify the communication with PROFIBUS with filter plant (s7-200 PLC with installed EM277 commanding processor). - Modify the communication with PROFIBUS with DCS Sugar Plant system (EMERSON Delta V). Modify the communication just by the boiler through the DP/DP caplers. - Programme the two ways of reacting in case of loss of main power supply. Distinguish normal work and repair work. - Add controlling system with three new ash carriers. - Add controlling system with machine for coal spacing in coal bunker. - Modify the connection with Diamond cabinet (new system with self-control) on the boiler. - Add the two-way working possibility for spreader plant. The plant in local mod control without holding. - Secondary ID fan will be controlled with new frequency regulator through PROFIBUS. - Do the HMI application into WinCC v7.0. - Do the HMI application on two languages (English and Bosnian). |
