Thanks all @IO_Rack could you prehaps so me how a ladder would look for this please?   Thank you

Thank you pturmel, I will probably go ahead and do this method better. I would still like to know how to achieve with a roadless cylinder mind.   Thanks 

Only 2 positions. It is a odd size stroke required and I have used bumpers but they are not very effective. If i had a sensor for lower pos and then 1 for upper it would enable the operator to move the sensor up for different height products.    Thank you Glenn

Thanks for the replies all. I understand that this may not be the ideal solution but the budget is low and only have a few months because the company is closing. Can anybody please help me with the logic in the ladder for the description I have given. I just cant figure out how to do the ladder.  Thank you

Hello all, I have changed our machine from mechanical chains, cams and pusher rods because they are always failing. I installed 2 cylinders which are working much better. I need to control 1 of the said cylinders a little better. Currently it has a physical stop from preventing it going all the way down but we are having to move other aspects of the machine for the upper positions all the time. I am trying to understand how I do this with 2 x reed switch's. My idea is once the upper read switch is made apply air to both sides of the cylinder to hold a position. I would also like to do the same on the lower position. I appreciate accuracy is not going to brilliant but that's not a key issue for us. Can anybody please guide me? I    At x counter Ram Up activates. (Y001) Once upper reed switch is made activate  (Y001 & Y002) to hold upper position. At x counter Ram Down Activate (Y002) Once Lower reed switch is made activate  (Y001 & Y002) to hold lower position.   I have attached a sample of the toggling of outputs but no idea how to incorporate the switch's.   Thanks in advance. https://discord.gg/ZYjpDza9nu     Test.gxw

Hello all, would anybody please be able to cast an eye over my ladder. I have re-worked this several times but still feel I am doing the alarm section wrong.   I also have to incorporate minimum steam alarm and was hoping I can just set m10 again.     Thank you  Site Monitor Test.gxw

Hi all, I have 3 values set that I want to show different lamps for 1 K2000 2 K2500 And data coming from a pressure transducer < this is the actual value to compare to. Anything above 2500 should be green light Anything between 2500 & 2000 should be amber light Anything below 2000 should be a red light.   I have attached what I have so far, but I cant get my head around the above problem. I might add I am a newbie to plc but enjoying them so far. This site has helped me greatly so far so thought I would come and ask  my 1st question MAIN.csv
