Make sure u need to do the star/delta wiring as usual but to energize the relay is the output from the PLC..Ok!
 
Don't forget the mechanical interlocks -
Why bother with it anyway ?
 
Star Delta Ladder Diagram Example

Constructing a circuit for Star Delta control system with PLC ladder program is similar to wiring a physical relay controlled star delta system. The only difference when using a PLC is the absence of the physical relay control circuit which is constructed inside the PLC memory.
