normal open and normal close contacts in the Ladder logic explained

[@gvenagas]

Good evening! Forgive me if I am wrong but I have found some things that hinder my understanding of the terms NO/NC physical contacts and MAKE/BRAKE XIO/XIC internal PLC logical contacts.
First, i tend to believe that a circuit is activated when there is some action (pressing a physical button or contact by the user or when the physical relay coil is energised and therefore magnetizes the contacts.
Second, i tend to consider the user physical switches and the logical internal contacts of the PLC program as contacts of one state, because that way the brain thinks more simply, while they are two states by definition (double throw). So even in the case of non-activation by the user or PLC program there may be an active circuit/load.
With the terms NO/NC I personally like to refer to the user physical buttons or contacts while with the terms XIC/XIO, MAKE/BREAK the logical contacts inside the PLC program that are activated by the user.
To what extent am I correct in my words? Thanks!

I want long video with encoder tia portal

hi thanks , what do you want to do with encoder ?

@@EASYPLCTRAINING how to connect an encoder to cpu. for example with a machine tool. there is for example a motor with an incremental encoder on the x-axis. how to process the signal so that hmi shows movement along the x axis. Make a button on hmi and when pressed to reach the limit switch and it was 0 on the x-axis
