Please someone explain the wiring of DI AND DO OF PLC that how it is connected to field for getting DI (DIGITAL I/P) from switches and DO (digital output) going to field devices.

and also when DO is generated from PLC and suppose relay is provided for energizing SOV (110V) in field FOR trip contact, in that case how that combination of wiring for DO and relay is made for energizing that field device (SOV 110V)?

i am new in this topic so have a word for it.
thanks in advance.
 
You are confusing me.

Maybe you can borrow one of your classmates notes or read the assignment again.

You will not learn properly if we do your home-work for you.
