Hello. I have a m221 and use basic somaks to programe it. The problem is the following. I use %mw0:x0 to allocate a button on off HMI, If on the HMI press the button to set him "ON",and pull the voltage from HMI and M221, when power supply, the button is still "ON", it does not return to an initial state "OFF". HMI i use a Weintek 8070 programmed with easybuilder pro. How can I do that when I power the HMI and M221, the button to be OFF, even if the voltage was off when the button was ON. Thank you.
