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...

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...
I assume that you are after Siemens Step7 Microwin, the software for programming S7200's? You will also need the PC/PPI cable to connect to the S7200, you cannot 'roll your own' cable, they contain a converter, you will need to buy one, you will also need to buy the microwin software. Speak to...
Phil,
I am not sure if there are any 'generic' books that cover what you want. But, if you chose to work with Siemens PLC's then I can reccomend the books by Hans Berger. 'automating with step 7 in LAD and FBD' and 'automating with step 7 in STL and SLC'.

There are 10 types of people...
I haven't used any HART products, but I do know that Siemens have interface cards for their 300 range of PLC's.
The part numbers are:-
6ES7 331-7TB00-0AB0 and 6ES7 332-5TB00-0AB0
The 331 is a SM331 analogue input module, 2 channel and the 332 is a SM332 analogue output module also 2 channel...
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.

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...
