  1. Hello Sir, thanks for the reply. all the 4 inputs have been located and labeled as required. they are additional 4 inputs also used for flow rate. but i did not locate them on the data input file.  am doing direct verification's from the inputs and outputs once am done i will come out with documents identifying what input goes to were, and same with the output.  (nope... just need someone who has done PLC programming,. one person is plenty. you should be the one watching over the shoulder.) ( i studied electrical and control engineering, i did PLC programming as well, but am a fresher, coming across tasks like this builds me with a good experience) (remember the story of Thomas Edison and 2000 filament) once more sir thank for you constant contribution i appreciate.    
  2. Hello Sir thanks for the contribution. i need to understand the ladder logic diagrams first. looking at ladder 5 you will see real world outputs as indicated in the electrical diagrams. now looking at the inputs of the ladder diagrams they are made up of registers , in this situation how do i figure out the real time input. coz if you check the input data file, it show some inputs are ON but i cant figure their locations on the diagrams.      
  3. Hi, thanks for the reply, since  ( It sounds like you really need someone to look over your shoulder as you work through this ) you are right. as it requires collective ideas coz the task is tough !

  5. HMI Documents  HMI manual.pdf
  6. Hi, so far  i got some documents from the manufacturer, while trying to study the documents, please i will still need more elaboration from this forum thanks  electrical diagrams.pdf
  7. this is for the HMI

  8. Hi, Joe E,

    please find attached  some part of the documents

  9. Hi sir, thanks for the reply. am working hard to get the documents.
  10. Hi Joe,  i have written to the company. but no respond yet. i even called the technical support center, it seems the receptionist is not all that conversant with English language, how ever she said i should get back to her by 2 pm Italian time today.  
  11. please here is the project.  PLC1.RSS
  12. thank you very much sir' you have made enough effort to encourage me , sincerely i appreciate . thanks once more!
  13. nope, before i visited the location the HMI was not powering up. i have written to the company who did the job. requesting for some documents they are based in Italy     
  14. Sir, i think before talking of replacing the HMI, i should get some better understanding how the program functions, for example i need to create an application in the HMI that enables the operator to target the quantity of product he need, like when he inputs 1000 gallons, once its achieved the valve switches off automatically !  so please i need some guidance on how to approach this task
