as you said, stop push button always should be normally closed for emergency but you put it in the program as a closed contact so you made it normally open. you should've put it as an open contact to avoid confusion. Electrical engineers tend to do the same what you have did because it is hard for their imagination current will drive through when the stop contact is open. It is easy to think like that, any switch whether is push button or sensor meant to stop the process, should be programmed as an open contact to be normally closed as a physical or in reality (This only work for ladder program not for SR ). Thank you
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!
#3 could be worded better wouldn’t want to bank on technicians trying to understand my grammar vs getting my valves turned on and off. But awesome video
I am definitely 'latched' to your videos
I really liked the videos 👌 , understood very easyly Ty.

How can I program the automation for refrigeration??? What are the symbol in PLC that I will be use for pressure transducer and temperature sensor?

Thank you mam...
What is the name of the software you use to create the ladder logic
Very interesting video but are u give training or not
#3 could be worded better wouldn’t want to bank on technicians trying to understand my grammar vs getting my valves turned on and off. But awesome video
Thank u
THANKS
Mam, Could I attend class?
Madam you put DCS programming videos
Is good watching video I like gratzee
Good explanation but its may be in Tamil,better for understanding for beginners
Mam software ka naam kya hai
CX programmer
Until released ..duh
