Good Afternoon Community,    I will like to know your experience with the autotuning function of the PID of M580. I have used autotuning with the M221 and I got mixed results. I have test order autotuning methods for example in siemens 1200 with great results. It will be great if you people have a tutorial, guide or recommendations on how to achieve it in the M580, so I can reach it´s full potential on this PLC.   Thank you very much.   ... View more

Hello community,    I'm looking for a function that can derive in the M580. Last week a client of us had big accident in one of their machines. This failure occured because of a component that was too old, the machine did trip because of another failure signal that appeared a seconds later. I don't want to anticipate the failure because it will be impossible, I want to trip the machine when the failure occurs. For example, of all the variable of the machine we saw to critics change, the pressure of the circulating water of the machine drops 1.3 bar in 4 seconds which is dangerous, the speed of this change in such a short time is the one I want to evaluate, so I can make a new trip. Any ideas people? I thought of a derivating function. Thank you very much.    ... View more

Hello Everybody,   I will like to know why is necessary to use the NOE with a M340. I know when using the NOE it enables the IO Scanning but I know that the M340 has a modbus tcpip port and you can use the READ VAR to read register from other devices. What is the advantage of using the io scanning instead of the function block READ VAR? Does it really gives me an advantage using the NOE? Thank you very much for your time.  ... View more
