Hello All,

I am using an S7 300 series PLC and WinCC flex 2008. I have been trying to create a process timer whichneeds to be displayed on the HMIand triggered by an event (start atomization). The timer will also need to be stopped by an event and then reset post datalogging.I would like to know how to best approach the PLC logic portion (timer or counter).I have used an I/O field for the HMI timer display and a button for the reset. Your collective knowledge would be greatly appreciated. Thank you!
