I have two pumps in WASTE WATER TANK. Each pump is protected with MOTOR PROTECTED SWITCH from thermal overload, and has contactor which will turn on the pump.
Waste water tank has hydrostatic probe for measurement level of the tank, also waste water tank has 4 level floats for controling pumps.
PLC PROGRAM: I want somone who can make PLC program like Ladder diagram (S7 300) who will control work of the pumps. As i said level floats will control work of pumps.
1st level float (LOW LOW LEVEL) will be for the turning off pumps (in case that the second level float is corrupted)
2nd level float (LOW LEVEL) will be for the turning off pumps
3rd level float (HIGH LEVEL) will be for the turning on pumps
4th level float (HIGH HIGH LEVEL) will be for the turning on pumps (in case that the third level float is corrupted)
Pump must work in FLIP/FLOP mode, each time must be turned ON different pump.
In case that one pump is corrupted then other pump must be always turned on when HIGH LEVEL will come.
Each pump must have his own count of working hours.
PLC SIMULATION: This situation must be made IN PLC SIMULATION (Digital Inputs/outputs). And when you send me a program everything must be working
For SCADA (TIA): on screen must be show process, waste water tank, pumps, hydrostatic probe and level floats. Level of waste water in tank must be seen (How is going up or down
VIDEO: Freelancer who is hired must make video explanation about PLC program, PLC simulation and SCADA how is everything made Functions, etc...
In short when I watch video that i know to make everything like YOU
Video must be in format 1280x710 HD excellent quality
Freelancer must know to work in video editing software (After Effects).
For explanation freelancer must have great ENGLISH knowledge with ENGLISH ACCENT
In short everything must be explained easy to understand, clearly explained
Example of video with good explanation: [login to view URL]
- Great PLC programing, PLC simulation and SCADA knowledge
- Great ENGLISH speaking skills
- Knowledge of VIDDEO EDITING
BUDGET: mutual agreement

hi, i am a 10 years experienced PLC programmer have done lot of programs for process and machines. i am interested in this project, kindly visit my profile. thank you
I have been a writer for up to three years and have the skills and knowledge needed.I have carefully read your job and i assure you that i can comfortably handle it .Please assign it to me Thank you
Hi, according to the plc program i think that would be easy, but i will face some problems with scada by tia i can make it by indusoft program if you do not mind. By the way u r my first client :)
I have done various projects on Waste Water Treatment Plant so i know very well what problems occur during development of program, What instruments used in that project.
