From the answer and the picture above...
On hardwire ....1 input (No or Nc it does'n matter depend on result)
connected to input terminal of PLC..for ex. input 1 or call In 1
In program section... that input adress(in 1) ..We can make multiple
contact either No or NC contact ..(many contacts (In 1)can make up to the memory of PLC.( concern about the condition that you want)
If In 1 at hard wire has change the condition form NO(Normally Open
to close ..means that supply to input terminal or in 1 on
The Contact (In 1) in the program will change too..
from No.( Normally Open) to close
from NC.( Normally Close)to open
The condition in this program depend on designer or programmer want
Which I/O will turn on or turn off..
My answer may be not clear may be because of my lag in English..sorry
if you could not understand my explanation.
From the pictures of Prof. Terry Wood (I learn a lot from his's answer in this plc forum)I think already clear...
