    I am studying a book by frank petruzella called programmable logic controllers, the lab manual

    im on chapter 2, plc hardware components.
    I have this question to answer

    "write a documented program that will simulate the input, output and data table conditions for the plc circuit shown below. use the I/O simulator screen and the following addresses to simulate the program

    NC pushbutton_I:1/1
    NO limit switch_I:1/8

    observe the status of the bits stored in the input and output image tables"

    then there is a drawing of two switches, an input module, processor memory input image table, then, processor memory output image table, output module and two lamps, one for output on and the other, output off.
    im not sure how im supposed to do this. there is no ladder drawing as such.
    im supposed to read the accompanying book of the same name (minus the lab manual bit), I don't have it.
    im not sure how im supposed to do this.
    there is no other information, the second question is about data tables.

    any help would be great!!

    What is the PLC this is designed around? I don't recognize the designations, but there is not sufficient info here to see what exactly is needed?
    There is not much int the way of I/O so I assume it is a very basic question?
    It sounds like you need 'the book'?
