Hello everybody. Before placing my doubt i request you to open the link given below.
http://www.plcs.net/chapters/respdetails6.htm
It is the page "effects of response time" from Learn PLC's section of this website itself. The last example given at the bottom of page shows this diagram.[FONT=Arial, Helvetica, sans-serif][SIZE=-1]
They have said [/SIZE][/FONT][FONT=Arial, Helvetica, sans-serif][SIZE=-1] (worst case because the input is not seen until scan 2). But as can be seen from the figure the input is getting on in the 'in' mode of scan 1 itself. So how is it that input is not seen until scan 2?
Please rectify me if i am wrong in understanding the example. Thank you.
