1.9 Basic Program Design Examples<br />

Example 1 - Stop First latched circuit<br />

When X1 (START) = ON and X2 (STOP) = OFF, Y1 will be ON.<br />

Y1<br />

X2<br />

Y1<br />

If X2 is turned on, Y1 will be OFF. This is a Stop First circuit<br />

X1<br />

because STOP button has the control priority than START<br />
