DESIGN PHILOSOPHY
Math/compare logic (or PID) for Siemens PLC.
4 x vessels liquid levels are monitored by 4-20mA level sensors (A1, A2,A3 & A4). Levels are to rise within vessels at approximately same rate.
Control of liquid entering vessels is by 4 x On/Off "fill" solenoid valves.
Upon "Fill Start" command, commence filling of vessels by energising solenoids S1, S2, S3 & S4. Maintain levels within nominal 2% of each other.
If A1 <2% deviation from A2, A3 or A4 - Pause S2, S3 &/or S4.
If A1 >2% deviation from A2, A3 or A4 - Pause S1.
S1 to re-open when A1 = Average of A2,A3 & A4 (or = A2, A3 or A4).
If A2 <2% deviation from A1, A3 or A4 - Pause S1, S3 or S4.
If A2 >2% deviation from A1, A3 or A4 - Pause S2.
S2 to re-open when A2 = Average of A1,A3 & A4.
If A3 <2% deviation from A1, A2 or A4 - Pause S1, S2 or S4.
If A3 >2% deviation from A1, A2 or A4 - Pause S3.
S3 to re-open when A3 = Average of A1,A2 & A4.
If A4 <2% deviation from A1, A2 or A3 - Pause S1, S2 or S3.
If A4 >2% deviation from A1, A2 or A3 - Pause S4.
S4 to re-open when A4 = Average of A1,A2 & A3.
When "Empty" command received, tank is to empty in same manner, ie: tanks are to empty maintaining 2% error by controlling 4 x On/Off "empty" solenoid valves.
Selectable......
Process using 2 x vessels only.
Process using 3 vessels only.
Process using all 4 x vessels.

Hi, What hardware would you like to use for this project. Is it possible that we can do this project using microcontroller.
Hi, Your bid is very similar to my profile, and i can handle the ladder logic or PID Programming Please go-through my profile, looking forward for your reply Thanks ramkumar 9703870141
I am an electronics engineer with a flair for automation. I have prior programming experience in programming Siemens S7-200 PLC and SCADA.. Hence, I possess the skills required for your project and hope to be awarded.
More than 10 years of experience in Automation industry with PID based constrols. Experience in Electrical and Hydraulic PID control.
Hello, please see my profile. If i understand it right it's controlling filling/emptiying vessels at same rate with levels not exceeding some boundaries. What platform and what lannguage ? I would go with SCL.
We are into Process automation and handled multiple logic of the same manner. With a team of 35 engineers, we will be able to deliver high quality in stipulated time.
Having 10 years of experience in PLC programming and commissioning. worked with S5, S7-200,1200,300,400 and 400 H systems.
Hi, this project seems to be right down my alley. I have years of experience in doing process automation and tank level control being one of them. I will also provide a Graphic Interface (HMI) for easier simulation pr 更多
