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.

Sir please upload a 200smart encoder control and v90 with PTIor turq control

We can not use two output at one rung I think it may be wrong

[@AutomationRevolution]

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 ?

[@AutomationRevolution]

+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.
