    PLC Based Control System. 1 day left

    See the attached file for more details Motivation: This project is motivated by the need for an automated safety system for the steam generating unit of a company. This system is required in the company following an accident that occurred in the company due to a miss communication between the maintenance and operation teams that resulted in collapse of a tank. A safety relief valve used to maintain pressure inside the tank was removed during maintenance and the operation team resumed operation before the valve was restored leading to a vacuum in the tank that leads to the collapse of the tank. By having a system to automatically monitor pressure inside the tank and alert the operation team in case of pressure imbalance, such accidents can be minimized considerably. In all industries, equipment such as motors, pumps, belts, gear trains and couplers are subject to wear and tear during use that would eventually result in an unscheduled shutdown. Cavitation one of the areas of interest of this research results in deterioration of the performance of pumps that may lead to failure of the pump. These unscheduled shutdowns lead to idle personnel and equipment that are usually expensive to maintain. By early detection of cavitation, these maintenance costs can be avoided. The motivation for this project, therefore, is to design a cost-effective, efficient system that automatically diagnoses pumps for degradation and cavitation to be able to predict pump failure thus decrease the large costs associated with idle equipment and personnel due to unscheduled shutdowns. Objectives: The main objective of this project is to develop a simulation of a system that would improve safety in a steam production unit by use of sensors interfaced to a controller which controls actuators such as valves and an alarm. This main objective would be based on an accident that happened in a steam production unit of the company. Another major objective is to design a system for automatically monitoring cavitation in a water pump. To achieve these objectives, research must be done on the safety measures that are currently used in a steam production plant of a chemical products company, possible areas and areas disposed to accidents should be identified, causes, effects and ways of detecting cavitation have to be investigated then systems designed to improve safety of the steam production unit and to monitor cavitation.

Deliver the server first. • A test application that will work with some Historian that supports OPC. Allow us to test the finished solution with it also. Must specify the Historian intended to be used. • The DLLs must not just be the examples downloaded off the some web site which don’t have the source code. • Need full source code for the internal part of the server & client. We need this source code in case we have errors or need to do optimization later. • It can have dependencies on PUBLIC and FREELY, UNENCUMBERED AVAILABLE libraries if necessary. • Works with latest .NET framework & Builds in latest MS Visual Studio as a .net standard library (preferred). We already have the UA data access version built. More info on OPC may be obtained from OPC Foundation website. You have to provide training to us for at least 8 hours to explain the coding topology-structure made in the project & also help encapsulate it into our code project successfully. The budget is flexible. Complete source code in current form, with detailed documentation for this project, need to be submitted before any payment will be released. The code & all deliverable will become our property. Please specify your team's hours (in GMT) when they will be readily available via phone etc. We expect a week time of delivery from you after the award or specify the time of delivery. Provide us with rough milestones (if any) tied to payments. no upfront. Delays will cause problems for our project. DO NOT PROVIDE ANY IRRELEVANT INFO IN YOUR RESPONSE.

    pump control pool Ended

    I am using an s7-1200 PLC. I need someone to write the ladder logic for it please. it has a master 3 position switch. Pump off.. Pump On.. Pump Auto There are 3 valves to control and there are 2 water level sensors. One sensor is full and one is empty. They are float type switches. Pump will turn on manual if selected, only if the low level switch is not activated. if the low level switch is activated while the pump is running it will stop the pump until the low level switch is normal. then the pump will restart. it will output a light buzzer. Pump will turn on to the auto mode, signal provided by a timer relay, if selected, only if the low level switch is not activated. if the low level switch is activated while the pump is running it will stop the pump until the low level switch is normal. then the pump will restart. it will output a light buzzer. If the low level switch is activated (closed) (NO), it will activate the light buzzer output signal as above. if the low level switch is activated it will open a valve. (refill) (refill valve open command is maintained for 35 seconds) . the refill valve will remain open until the high level switch is activated (CLOSED) (NO) AND the low level switch is (OPEN) - the REFILL valve is then sent a closed signal for 50 seconds. The second valve (surge Valve) will open when the motor is on in auto or manual mode only. If there is no motor on command the surge valve will be sent a closed signal for 60 seconds. when the motor start command is received the SURGE valve will be sent an open signal for 60 seconds. If the motor is stopped because of low level, the SURGE valve will receive a closed command for 60 seconds. The last valve is called VACUUM. It has an On OFF toggle switch. when switched on it will close the SURGE VALVE (60 seconds command) and open the VACUUM Valve for 60 seconds. it will start the pump (provided no low level signal exists). after 4 hours elapsed time it will revert the control back to the auto command or manual command depends on the switch. If manual is on, then it will CLOSE the VACUUM for 60 seconds and OPEN the SURGE FOR 60 SECONDS and the motor will remain on due to the MANUAL ON SELECTION. IF AUTO is on, CLOSE the VACUUM for 60 seconds and OPEN the SURGE FOR 60 SECONDS and the pump is on or off depending on the manual timer. LIGHTS has a pushbutton momentary switch. ON leaves the output on for 4 hours - OFF is off immediately. Push on push off. relay outputs from the S7-1200 Q0.0 PUMP RUN Q0.1 LIGHTS ON Q0.2 FAULT BUZZER Q0.3 PUMP ON LED Q0.4 SURGE OPEN Q0.5 SURGE CLOSE Q0.6 REFILL OPEN Q0.7 REFILL CLOSE Q1.0 VACUUM OPEN Q1.1 VACUUM CLOSE Inputs A0.0 Pump off A0.1 Pump MAN on A0.2 Pump AUTO on A0.3 VAC momentary push button A0.4 High Float switch A0.5 Low float switch

    This project (hopefully the first of many), will be based on making an alternative designed 'check weigher' for my very small factory. I need to take a minimum of 50 bottles per day off of my conveyor belt, weight them on a load cell, then have that weight automatically recorded and alert me if it is out of tolerance. The bottle must then be put back on to the conveyor belt. For the initial prototype I would need a simple Bill Of Materials to be created using [url removed, login to view], and assistance with the PLC programme. I will be using a Siemens Logo 8 most likely, but Arduino or other alternative systems would be OK too. We are looking to strike the best compromise between price and functionality. I would ask you to look at my initial ideas, make them better where possible, and then help me to design the hardware set up that is needed to operate it. If you think that there is a better way of doing what I'm aiming for then we can start from scratch! It is quite simple stuff (in my opinion). My initial (untested) thoughts were that I could set up a couple of pneumatic pistons to act as gates on the conveyor, (running 1,000 to 2,000 bottles per hour) then push a bottle on to a load cell adjacent to the conveyor (while releasing the gates to allow the other bottles down the line), have the load cell record the weight and alert me if it is outside of tolerances, then push it back on to the conveyor. As we would only be needing to weigh 50 bottles per day the requirements of the hardware should be quite low. Some parts will undoubtedly have to be hand fabricated here in-house. Alternative ideas are most welcome.
