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.

Electric power & control Engineer, have experience with PLC programming and have the ability to implement your project as you like at the time. I can start from now.
Am an expert in S7-1200 And i have done lot of project on S7-1200 PLC. Programming is my passion, i can modify/write the logic depending upon the requirement and Standard.
I am keen to work on this project as I first to know that shall I submit you a sample previous ladder logic program which I made for similar project.
As I understand your project , I can do a good job for you using my experience in SIEMENS and Industrial projects . also we can discusses some ideas to make your project better .
I have 2+ ears experience in PLC,SCADA and HMI programming. I have a post in an automation company.I am available everyday after lunch. Please study my portfolio.
