4-20, 0-10, 0-100... What are all these?

Do you know ladder language for plc or stl or gates or something else ? I know programming only with ladder or gates .
Have ever make a programm for plc? 

[spic0m]

A simple (and funny paradigm of ladder programming is below

1. ------[ ]--------------------------------[ ]-------------------------------------( )
      President button                          General button                            Nuclear holocaust

President button AND General button = Nuclear holocaust



                     chocolate flavor         
2.----[ ]--------------------|--[ ]--|-----------------------------------( )
     cone                             |         |                                    ice cream cone
                                        |         |
                                        |--[ ]--|
                                       vanilla flavor   

cone AND (chocolate flavor OR vanilla flavor) = ice cream cone


This is what it looks like and some comparisons you can make with the inputs you have. Serafino who knows the subject better will explain more i think.

Also there is a free programmer and simulator you can find here: http://www.entertron.com/software.htm

Thanks spicom for example. I think i am getting to understand.

Serafino as i tell, i have never make plc program but i wish to learn.

[serafino]

So your first step is to buy one small PLC ( it costs about 100 euros ) .
After we can help you for your first steps and you must also study and you will see that it is not so difficult.
SO FIND A PLC

Here you can download the demo software of aXL PLC - MITSUBISHI.http://www.mitsubishi-automation.com/products/microcontrollers.html
