The S7 Simulation PLC 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 and directly on the same PC. Even for project engineering S7 for Windows® or the original STEP®7 tool can be used. The program of a S7-PLC or a Siemens Win AC® SoftPLC can be transferred to the S7 Simulation PLC.
The communication between the Simulation S7 and S7 for Windows® or STEP®7 can be done directly, via TCP IP or with a zero- modem cable.
