Preface
S7-PLCSIM allows you to simulate the operation of an S7 programmable logic controller. You can test control programs with S7-PLCSIM without connecting to S7 hardware. S7-PLCSIM provides a graphical user interface for viewing and modifying control program variables, running the simulated PLC in single or continuous scan mode, and changing the operating mode of thesimulated controller. S7-PLCSIM also includes a COM object called S7ProSim that provides programmatic access to a simulated PLC. With S7ProSim, you can write software to perform such tasks as changing the keyswitch position of the simulated PLC, stepping through the control program a scan at a time, reading or writing controller values, and many other tasks. S7ProSim is not documented within thescope of this S7-PLCSIM online help system and manual. The S7ProSim online help system and PDF document the usage of S7ProSim. Audience This manual is intended for engineers, programmers, and maintenance personnel who have knowledge and experience with S7 programmable logic controllers and STEP 7 programming. Scope This document describes the features and the operation of S7-PLCSIM V5.4. Other...
