If M12=1 then ( if M2 =0 then (Set timer 10 preset value to 28 Set timer 11 preset value to 4) else (Set timer 10 preset value to 47 Set timer 11 preset value to 1) end if ) end if

Koyeap - many thanks that now makes a lot more sense. However in the following example what value does the timer %TM2 have? 25 or 50 ??

The timer has 50 as value multiplied with timebase 10ms so 0,5s (If you are online you will se the right value on timer..

Many thanks again. I am just trying to understand some of the code before I go on site next week. One more question concerning the second example above - What is the advantage of programming the %TM2 parameter with the "OPERATE" command instead of directly in the Timer ?

The advatage is that it is easier to make online changes to the timer with the operatte command. Her you also could say %TM2.P:=%MWx to make the time like an variable and just change it in a animationtable.
