The S7-Simulation-PLC is specifically created to provide an improved quality output to which the software will be used. The S7 provides a program in the exact action as a hardware PLC. The PLC status can be displayed in real time with no recompile activities. The Soft PLC promotes a replication unto the original SIMATIC® PLC in which the programming tools S7 can certainly be operated. The online connections can be achieved through the aid of the Ethernet which then is directly forwarded on the same PC. The S7 can also be utilized in project engineering purposes. The program of S7-PLC can be transmitted to the S7 Simulation PLC.
