Fieldbus Simulator - PC-based or otherwise

I am looking for a decent Fieldbus emulation package.

Would you guys recommend a package that can simulation multiple H1 segments ?

Much obliged.

Not quite sure what you are looking for but Wago have a very good fieldbus setup with multiple options - Prfibus, Profinet, Ethernet I/P, Device Net etc etc - just change the processor the I/O remains the same. You can download their demo software at www.wago.com.
