The Stop button is a normally closed button, meaning that the signal that normally we receive from it is True. In the Ladder program, normal contact is used to check the state of the Stop button. As far as Stop button is not pressed, the normal contact will be True. Once the Stop is pressed, the corresponding normal contact will become False, and this is what we need. On the other hand, if we use the negated contact, its normal value will be False, and when the Stop button is pressed it will become True. I hope this helps you.
Just found this on the web. Though not sure what it provides on top of what you can find on my channel! www.ebay.com/itm/PLC-Structured-Text-with-CODESYS-V3-5-Simulation-PLC-HMI-Visualization-/162602556503?hash=item25dbde1c57:g:TK8AAOSwwpdW5JLw

Can you somehow adjust voice loudness? It's much to quiet.
Sorry, I did not realize this. I will fix it and then make the video public again.
I just double checked it using another PC. The audio looks fine, so I made it public again. It would be nice to know how other viewers find it.
yea it is still very low but it s not that big of deal i can rise the volume on my pc
Shouldn't stop have been a normally closed contact?
