I just want to get a signal output in sunchronizing with real time clock of cpu. In this tutorial we ll be looking at displaying a running timer on hmi in a proper format.

To do that we ll convert ltime which is the timers current value to a number of strings hours minutes seconds etc and combine them in to a single string to be displayed on the hmi. The centerpiece is the simatic profinet stack which has been proven in use for many years. Access for clock synchronous access to real time data for profinet via irt extremely short cycle times with high precision clock rates jitter accuracy isochronous mode and. The signal state at the output q will continue to be 1.
