    Siemens S7-200 edit program

    I understand what you are after now, I don't think you are able to open the files via a text editor, only with the correct software. If it will help you out, you could email me the program files and I can open them using microwin, then 'print' them to a PDF file for you. The choice is yours...

    bmsg The simple answer to your question is no, the solenoid will not operate if it requires a minimum of 22v. The length of cable run is 800m (not 1600), you qoute the resistivity of 1.5mm cable as 13.14ohms, that means the 800m run will have a total resistance of 10.51ohms. The rating of...

    ground problem

    If I have understood your problem correctly, then grounding the 0v DC line will probably cure it. This will also ensure that should a ground fault occur, the over current protection on the 24v DC will operate. Paul

    MORE INFO S7300 plc PID control for modulating burner motor

    Hi Tweed the function block you require in step 7 is FB41, I have never used this FB, so I can't help you much there. I know that this has been discussed at Phil Melore's site ( http://www.plctalk.net/qanda/ ), it might be worth your while having a visit and posting your question there. I...
