- When you beginner in PLC programming and confused where to start PLC program and how to make Ladder logic and how to design network, i hope this video really help you a lot. We will also upload total series of PLC program step by step. Here in this video you will learn about how to use NO, NC contact in network ladder and latch contact in push button type inputs.

I'm sorry if I'm wrong because I'm not an expert in PLCs, but as I understand the memory bits of a PLC simulate physical switches and push buttons. By their nature, the bits are in state (0), which is why a MAKE command coincides with a switch that changes from an open state (0) to (1) when the switch is pressed by user, but this does not happen with a BREAK command that in order to is valid, the PLC memory bit which, as we said, is in a normal state (0) should become (1), that is why the electrical continuity of the circuit does not coincide with the logic BREAK command of the PLC, which in order to be valid, the memory bit must from (0) to (1) when the user presses the switch. I hope I didn't make the situation worse.
very interesting and good explain sir.thank you hope more tutorial.
Thanks, Pls share & subscribe this channel.
Sir please upload a 200smart encoder control and v90 with PTIor turq control
nice information and video for begineers
We can not use two output at one rung
I think it may be wrong
Hi You can use two outputs in one rung it's totally depends upon condition.
Sir,
Can you please do the question by using a NC switch to start and NO switch to stop ?
+Arjun Thomas You can use Positive and Negative trigger bit as set and reset and from that memory bit you can make NC as start and NO for stop.
