SM35-J-RA22, Count up or down timer on the HMI screen

Recommended Posts


I have a project were after intervals of 15mins, It reads a value. Is there a way to show on the HMI a count down/count up from the timer? 


I currently use a Variable: Timer Current and Variable: Timer Preset. But neither seem to display right. It could be due to the fact that I'm not sure how to display the format.
