From the developer:
The SoftPLC S7-315® / S7-416® executes a program in the same manner as a hardware PLC. The advantage of executing a PLC program this way is, that the PLC status can be displayed in real time without any recompile activities. Since the Soft PLC behaves like a original SIMATIC® PLC, the programming tools S7 for Windows® and STEP®7 can be used. Online connections can be established serial, via Ethernet, via PROFIBUS DP and directly on the same PC.
