The upgrade project consisted of the design & construction of a new Programmable Logic Controller (PLC) and Supervisory Control And Data Acquisition (SCADA) system to eventually replace the existing legacy Honeywell/Experion system and equipment which is nearing the end of its life cycle. The new chemical sludge handling PLC, incorporates hot standby Siemens S7400H processors utilising a Media Redundancy Protocol (MRP) remote Input/Output (RIO) network allowing simultaneous PLC and network failure without process interruption.

*SUPERSEDURE NOTICE - This Technical Manual supersedes TM 9-1010-230-23&P dated 30 November 2005, inlcuding all changes.

Control: The SCADA should allow the operator to control the devices directly from the SCADA control room.

CE 1.3.3 I studied plant system architecture and the interfaces with the distributed control system (DCS) and emergency control system (ESD) of Honeywell,as this was key aspect for interface. Since the data like signal values, alarms, trips etc. from MCMS was serially interfaced by either Modbus or OPC(OLE for Process Control) to DCS .The trip signals from MCMS system was hardwired signals to ESD, since these are very critical signals for machine shut down.

The control system of the automated warehouse include management/monitor computer, master PLC and lower PLC, which are connected by Modibus and wireless networks and can build up a complete multilevel computer monitoring system, as shown in Figure 2.2. The whole automated warehouse system integrated cargo storage, retrieval, distribution and transportation together, realizes intelligence operations in the whole system, and is an intelligent warehouse without any manual operation.

The conceptual framework for the deployed system is given bellow. The framework contains one Coordinator which is connected to the control station computer through USB cable, four routers and three sensor devices. Data packets from the sensor device are transmitted to the coordinator via multi-hop routing.

In this project work, LPC2148 ARM7TDMI microcontroller is used. The Microcontroller works according to the program written in it. The idea is that the microcontroller will be placed in the Robot to calculate the quality of water and control the movement of robot (Forward, Backward, Upward and Downward). It also has GPS and GSM module which is controlled by the microcontroller.

and monitoring and control mechanisms are covered in this section. The project 's technical process plan is covered next, reviewing such things

The project shall install wastewater treatment system. The wastewater shall be treated to meet the effluent standard, then discharging out of the power plant and shall be connected by OWNER at 1m out of boundary of the power plant.

In the aspect of the quality of program implementation, the question that must be answered is how much the suitability of competence provided by Vocational Technology group with the required

Then proposed system is been designed. Plans are prepared concerning with the physical construction, hardware, operating systems, and

Note: All the readings and calculations are performed at “outside station”. It uses the control Logix platform utilizing a GuardLogix safety PLC.

3. In case of fixed guard is not possible then use an interlocked guard which ensures that machine did not start before the guard is closed and machine stops when the guard is opened while operating the machines.

Certified that this report is prepared based on the term paper project undertaken by me in GENERAL MOTORS BANRUPTCY under the able guidance of Dr.Richa Raghuvanshi in partial fulfillment of the requirement for award of degree of B.Com(H) from Amity University, Uttar Pradesh.

The aim of this project is to construct a single phasing monitor and prevention system using 8bit microcontroller. Anti-single phasing relays or single phasing preventer are required for critical
