Sir l've followed your instructions. But this program isn't working. After stopping the PLC my programme is going to again restart (not resume). Others operations are running properly. I'm using simulator.
Hi Milan, you need to check which "S" variables can be use. For example in ISPSoft should be used: Initial step (latched*) => S0 ~ S9, 10 points Zero return (latched*) => S10 ~ S19, 10 points (used with IST instruction) Latched* =>S20 ~ S127, 108 points These viable vary between PLCs, see the manual
good video sir
Thanks a lot for this video

Sir, In my PLC, there is a loop error. How to solve..?
What kind of loop error?
@@LearnPLCinHindiSir it's solved. Same data registers were used to move same values but in different conditions...
Hi nice video ! Can I know the function of step ladder instruction? why dont we just use M auxiliary relay
Step is retentive and can easily be used to make a sequence :)
