Example

Equation: F8:80 = 0;

Ladder Logic Solution

Set all the bits for the float word F8:80.

Example

Equation: C5:80.PRE = 0;

Ladder Logic Solution

Set all the bits for the counter preset value C5:80.PRE.

Example

Equation: T4:80.ACC = 0;

Ladder Logic Solution

Set all the bits for the Timer accumulation value T4:80.ACC.
