Set and Reset of Counter in Siemens PLC

For example,

I writing a ladder logic to turn ON Q0.0(Output) using I0.0(input 1)

So whenever in am turn on input output turn on,If I turn Off input output will get off.See below image,

Now,To turn ON a output continuously,We can use Set function.

Even though You turn off I0.1,Output Q0.1 remains on,Find below image,

To turn Off Q0.1,We can use other switch with Reset bit,

So,Whenever we use Set function Reset function also is mandatory.Both set and reset should have same address.

Thanks For Request to answer,
