Transfer function into AC700F

Yes, of course. Thats what control systems are for

OK, so given that this is a teaching exercise, I'm not sure its appropriate to just give you a finished answer. ( There isnt a one-button magic answer anyway ) What, Specifically, are you needing a hint with ?
>"Start with programming a simulation of the transfer function"
Personally, I'd "cheat" and use the pre made function blocks that come with the PLC rather than program everything from scratch.
You will probably find this task easier to program in FBD ( Function Block Diagram )
The PLC has number of premade function blocks that can be combined to produce the same effect as your transfer function. These function blocks include things like, first order filters, second order filters, integrators and deadtime delays. You will need to check the documentation of your chosen PLC to find which pre-programmed functions are already available.
If you want to code a transfer function that is a first order response ( ie 1/(Ts+1) ) then this is a first order filter block where the time constant is Ts
By adding together the various components that make up your transfer function using the matching PLC Function Blocks you can construct reasonably complicated transfer functions with a minimum of programming.
And at the end of the process, your program looks exactly like the Block Diagram of your transfer function.
