PLC logic is a digital computer used to automate electromechanical processes. The Star delta diagram is a diagram for a simple circuit that has the capabilities of starting a high horse power motor. A star delta diagram can be drawn in PLC Logic.
12 lead out motor is generally with two different set of winding usually for double speed application. 6 lead connection is to enable star delta starter. With 12 lead the motor can be connected in star delta and for two speed application. It is better to explain with proper wiring diagram only so that no mistake is done.

To perform a star-delta connection using a push button, you typically use a control circuit that includes relays or contactors. First, the push button is used to start the motor in star configuration, allowing for reduced voltage and lower starting current. After a predetermined time (often using a timer), the control circuit switches from the star to the delta configuration, allowing the motor to run at full voltage. This setup requires appropriate wiring and safety measures to ensure proper operation and protection of the motor.
The Star-Delta control circuit diagram shows the delta contact and the main contact.

One must check the design of the transformer windings. STAR - Delta or Star to star or Delta - star or Delta Delta. Wiring must be done accordingly.
In motor starters, this is usually done using contactors. Explanation of this can easily be done using a circuit diagram. There are three contactors, the main, star and delta contactors-all these contactors can be the same type. There are many ways of wiring a star delta but here I will only give a generalized answer. First, the main contactor and star contactors are energised thus the motor runs in star. After about 5 seconds, the timer which gets energized at the same time as the main and star contactors, switches its CONTACTS i.e the normally open closes and the normally close opens. This dienergize the star contactor and energized the delta contactor. Thus, the motor now runs in delta.

i don't know please help
Clymer manuals have a color wiring diagram
you have to buy the book...about $80
