Siemens Step 7 PLC Emulator/Simulator Freeware? PLCSIM alternatives?
(OP)
Ok so I know that SIMATIC S7-PLCSIM is out there to act as an emulator if you don't have a physical PLC to write and test programs with... but it is not free and don't think my company has it nor do I think I can get it approved as an expense.
Does anyone know of a good freeware version of something like this?
If not... what are good pay-for alternatives if any?

What if you don't have a physical PLC?

You throw you weight around in this and other threads as someone well-seasoned in industrial environments specifically related to automation and then say this. You can to plenty with a PLC Simulator... you can write programs with bits representing IO... you can write an HMI for it to test it... you can have a program virtually ready before any hardware shows up. Wow... think out of-of-the box a bit eh?

You can get a small PLC for not much money, perhaps even a bottom end S7.
You can get PLC programming software for a little money (even free for Design time only)
But you want it for Simatic S7 and for nothing.

Yah this is an exercise. Why should I pay. And... oh wait a minute and I forgot all PLCs process their programs, and have block elements that are all standardized across brands. So I can use any PLC right? [Sarcasm]

Talk nicely to your local Siemens rep, they might understand.

Anyway... I am not participating in this particular thread until someone tries to help more thoroughly address my original question... the rest of you can debate here, off-topic as long as you want... I am not here to have a philosophical/business-model debate... I posed a question and so far I have only a partial answer.

Your Sarcasm is misplaced (or rude).
Yes, you can use any PLC so long as it generates the signals your PC is looking for via an OPC link for example. If all your PC has to do when it is not talking to the resto of the world is represent daa coming from the PLC you could simple get any PLC (or indeed Emulator ) and then manually set bits/values to see the effect in your HMI.
Changing the OPC to address a different (the real)PLC should be easy.
