From many PLC developper have question in PLC simulator software which I am looking for a simulator of Siemens S7 PLC. I would like to suggest developper for PLC Siemens S7 software simulator ,we are starting with

WinAce software is a combination of step 7 (programming software)between Profibus-DP and PLCSIM drivers, it is a simulator S7-300/400 processor on the PC environment.
RSlogix simulator

When it is active, it controls a block of computer memory as if it were a PLC, you can download a program, select I / O addresses that you want to check and force, internal investigations and records the data blocks for the evolution of your logic.
I found a very good tool for debugging applications. You can buy it from Siemens for about half the price specified for Doug WinAce, contact your Siemens representative. I think the big difference is that WinAce is a PLC, but a soft PLC. It is an environment of complete control, and if you hang some Profibus I / O from your PC, you have an OS running. This is not a simulator - It’s the real deal.
Although PLC software is not quite ready for most control applications, they make excellent simulators.
We have joined our program to a SCADA system and will be used for training while the machine is installed.
Price, about $ 1300 dollars.
we are continue to next PLC S7 software simulator.
PLCSIM software
PLC-Sim software is a simulation package offer from Siemens mimics the behavior of a PLC without the need for an I / O. This solution works with STEP7 (no need WinAce or other PLC), and you download the control code that you wrote to the simulator, as you would a real robot. PLC-Sim can never control I / O.

I think and hope this article may be you in selection the Siemens PLC simulator software
I would like to suggest the resource in this please read more
