Twincat dynamic time setting.

[Horstoid]

Hi,
What is the best way to set dynamically time for TON timer ? Time should be in ms.

Example:
timer1: TON;
calculatedTime : UINT;

calculatedTime := x/y;

want to set that calulatedTime someway to PT:=calculatedTime ??
timer1(IN:=TRUE , PT:=t#xxxms , Q=> , ET=> );

timer1(IN:=TRUE , PT:=UINT_TO_TIME(calculatedTime) , Q=> , ET=> );
