Hello, I have a siemens s7-1200 PLC wich is connected to a HMI. I would like the ask 2 questions about how to communicate between the PLC and HMI => 1 I want to change te value of some tags so i can change te way my timers/couters work. How can i do this so dat when i change te value to for exameple "10" that the next time i power up the machine the value is still 10? I currently use a "local"Tag form a FB. The tag is in the static collum and has a start value as default.(see page 1) => 2 The PLC controls a couple of valves, i added i screen were i want to be able to manuele open or close the valves manualy. In the screen i added some switches whit an event for the on and for the off position. (see page 2) But when i put the switch in the on position the output flashes on and then off again really quickly. What can i do so dat it stays on? Thanks, Marc
